Dowty Ultra no longer exist. They were taken over by Parker Hannifin. Their series of gear pumps have now been replaced by Parker product which we can supply. Fortunately they are interchangeable units!

It wasn’t until the beginning of the industrial revolution when a British mechanic named Joseph Bramah applied the principle of Pascal’s law in the development of the first hydraulic press. In 1795, he patented his hydraulic press, known as the Bramah press. Bramah figured that if a small force on a small area would create a proportionally larger force on a larger area, the only limit to the force that a machine can exert is the area to which the pressure is applied.

Hydraulic systems can be found today in a wide variety of applications, from small assembly processes to integrated steel and paper mill applications. Hydraulics enable the operator to accomplish significant work (lifting heavy loads, turning a shaft, drilling precision holes, etc.) with a minimum investment in mechanical linkage through the application of Pascal’s law, which states:

The principle of Pascal’s law is realized in a hydraulic system by the hydraulic fluidthat is used to transmit the energy from one point to another. Because hydraulic fluid is nearly incompressible, it is able to transmit power instantaneously.

The purpose of the hydraulic reservoir is to hold a volume of fluid, transfer heat from the system, allow solid contaminants to settle and facilitate the release of air and moisture from the fluid.

The hydraulic pump transmits mechanical energy into hydraulic energy. This is done by the movement of fluid which is the transmission medium. There are several types of hydraulic pumps including gear, vane and piston. All of these pumps have different subtypes intended for specific applications such as a bent-axis piston pump or a variable displacement vane pump. All hydraulic pumps work on the same principle, which is to displace fluid volume against a resistant load or pressure.

Hydraulic valves are used in a system to start, stop and direct fluid flow. Hydraulic valves are made up of poppets or spools and can be actuated by means of pneumatic, hydraulic, electrical, manual or mechanical means.

Hydraulic actuators are the end result of Pascal’s law. This is where the hydraulic energy is converted back to mechanical energy. This can be done through use of a hydraulic cylinder which converts hydraulic energy into linear motion and work, or a hydraulic motor which converts hydraulic energy into rotary motion and work. As with hydraulic pumps, hydraulic cylinders and hydraulic motors have several different subtypes, each intended for specific design applications.

There are several components in a hydraulic system that are considered vital components due to cost of repair or criticality of mission, including pumps and valves. Several different configurations for pumps must be treated individually from a lubrication perspective. However, regardless of pump configuration, the selected lubricant should inhibit corrosion, meet viscosity requirements, exhibit thermal stability, and be easily identifiable (in case of a leak).

There are many variations of vane pumps available between manufacturers. They all work on similar design principles. A slotted rotor is coupled to the drive shaft and turns inside of a cam ring that is offset or eccentric to the drive shaft. Vanes are inserted into the rotor slots and follow the inner surface of the cam ring as the rotor turns.

The vanes and the inner surface of the cam rings are always in contact and are subject to high amounts of wear. As the two surfaces wear, the vanes come further out of their slot. Vane pumps deliver a steady flow at a high cost. Vane pumps operate at a normal viscosity range between 14 and 160 cSt at operating temperature. Vane pumps may not be suitable in critical high-pressure hydraulic systems where contamination and fluid quality are difficult to control. The performance of the fluid’s antiwear additive is generally very important with vane pumps.

As with all hydraulic pumps, piston pumps are available in fixed and variable displacement designs. Piston pumps are generally the most versatile and rugged pump type and offer a range of options for any type of system. Piston pumps can operate at pressures beyond 6000 psi, are highly efficient and produce comparatively little noise. Many designs of piston pumps also tend to resist wear better than other pump types. Piston pumps operate at a normal fluid viscosity range of 10 to 160 cSt.

There are two common types of gear pumps, internal and external. Each type has a variety of subtypes, but all of them develop flow by carrying fluid between the teeth of a meshing gear set. While generally less efficient than vane and piston pumps, gear pumps are often more tolerant of fluid contamination.

Internal gear pumps produce pressures up to 3000 to 3500 psi. These types of pumps offer a wide viscosity range up to 2200 cSt, depending on flow rate and are generally quiet. Internal gear pumps also have a high efficiency even at low fluid viscosity.

External gear pumps are common and can handle pressures up to 3000 to 3500 psi. These gear pumps offer an inexpensive, mid-pressure, mid-volume, fixed isplacement delivery to a system. Viscosity ranges for these types of pumps are limited to less than 300 cSt.

Today’s hydraulic fluids serve multiple purposes. The major function of a hydraulic fluid is to provide energy transmission through the system which enables work and motion to be accomplished. Hydraulic fluids are also responsible for lubrication, heat transfer and contamination control. When selecting a lubricant, consider the viscosity, seal compatibility, basestock and the additive package. Three common varieties of hydraulic fluids found on the market today are petroleum-based, water-based and synthetics.

Petroleum-based or mineral-based fluids are the most widely used fluids today. These fluids offer a low-cost, high quality, readily available selection. The properties of a mineral-based fluid depend on the additives used, the quality of the original crude oil and the refining process. Additives in a mineral-based fluid offer a range of specific performance characteristic. Common hydraulic fluid additives include rust and oxidation inhibitors (R&O), anticorrosion agents, demulsifiers, antiwear (AW) and extreme pressure (EP) agents, VI improvers and defoamants. Additionally, some of these lubricants contain colorful dyes, allowing you to easily identify leaks. Because hydraulic leaks are so costly (and common), this minor characteristic plays a huge role in extending the life of your equipment and saving your plant money and resources.

Elevated temperatures cause the water in the fluids to evaporate, which causes the viscosity to rise. Occasionally, distilled water will have to be added to the system to correct the balance of the fluid. Whenever these fluids are used, several system components must be checked for compatibility, including pumps, filters, plumbing, fittings and seal materials.

When choosing a hydraulic fluid, consider the following characteristics: viscosity, viscosity index, oxidation stability and wear resistance. These characteristics will determine how your fluid operates within your system. Fluid property testing is done in accordance with either American Society of Testing and Materials (ASTM) or other recognized standards organizations.

Viscosity (ASTM D445-97) is the measure of a fluid’s resistance to flow and shear. A fluid of higher viscosity will flow with higher resistance compared to a fluid with a low viscosity. Excessively high viscosity can contribute to high fluid temperature and greater energy consumption. Viscosity that is too high or too low can damage a system, and consequently, is the key factor when considering a hydraulic fluid.

Viscosity Index (ASTM D2270) is how the viscosity of a fluid changes with a change in temperature. A high VI fluid will maintain its viscosity over a broader temperature range than a low VI fluid of the same weight. High VI fluids are used where temperature extremes are expected. This is particularly important for hydraulic systems that operate outdoors.

Aside from these fundamental characteristics, another property to consider is visibiilty. If there is ever a hydraulic leak, you want to catch it early on so you don"t damage your equipment. Opting for adyed lubricant can help you spot leaks quickly, effectively saving your plant from machine failure.

When selecting lubricants, ensure that the lubricant performs efficiently at the operating parameters of the system pump or motor. It is useful to have a defined procedure to follow through the process. Consider a simple system with a fixed-displacement gear pump that drives a cylinder (Figure 2).

Collect all relevant data for the pump. This includes collecting all the design limitations and optimum operating characteristics from the manufacturer. What you are looking for is the optimum operating viscosity range for the pump in question. Minimum viscosity is 13 cSt, maximum viscosity is 54 cSt, and optimum viscosity is 23 cSt.

Check the actual operating temperature conditions of the pump during normal operation. This step is extremely important because it gives a reference point for comparing different fluids during operation. Pump normally operates at 92ºC.

Using the manufacturer’s data for the pump’s optimum operating viscosity, find the value on the vertical viscosity axis of the chart. Draw a horizontal line across the page until it hits the yellow viscosity vs. temperature line of the lubricant. Now draw a vertical line (green line, Figure 5) to the bottom of the chart from the yellow viscosity vs. temperature line where it is intersected by the horizontal optimum viscosity line. Where this line crosses, the temperature axis is the optimum operating temperature of the pump for this specific lubricant (69ºC).

Repeat Step 8 for maximum continuous and minimum continuous viscosities of the pump (brown lines, Figure 5). The area between the minimum and maximum temperatures is the minimum and maximum allowable operating temperature of the pump for the selected lubricant product.

Find the normal operating temperature of the pump on the chart using the heat gun scan done in Step 2. If the value is within the minimum and maximum temperatures as outlined on the chart, the fluid is suitable for use in the system. If it is not, you must change the fluid to a higher or lower viscosity grade accordingly. As shown in the chart, the normal operating conditions of the pump are out of the suitable range (brown area, Figure 5) for our particular lubricant and will have to be changed.

The purpose of hydraulic fluid consolidation is to reduce complexity and inventory. Caution must be observed to consider all of the critical fluid characteristics required for each system. Therefore, fluid consolidation needs to start at the system level. Consider the following when consolidating fluids:

Hydraulic systems are complicated fluid-based systems for transferring energy and converting that energy into useful work. Successful hydraulic operations require the careful selection of hydraulic fluids that meet the system demands. Viscosity selection is central to a correct fluid selection.

Pistons with O-ring seals operate in, fiberglass wrapped cylinders. The cylinder diameter is constant for a particular pump series. The driving medium pushes the piston down on the compression stroke and lifts it on the suction stroke (the M series has a spring return). No drive air lubricant is required as the piston is pre-lubricated during assembly.

In the hydraulic section, the drive piston connects to the hydraulic plunger/piston. Hydraulic pistons have different sizes depending on their nominal ratio. The higher ratio pumps can achieve higher pressures, but have smaller displacements, which translates to less flow per stroke.

During the down stroke, the inlet check valve keeps the liquid in the pump from flowing back into the suction line while it is compressed by the plunger. On the return or suction stroke, fresh liquid is drawn in through the inlet check valve, while the outlet check valve closes.

These check valves control the flow of liquid through the hydraulic section. They are spring-loaded and have a very low cracking pressure, which allows maximum flow during suction. Inlet check valves are closed by the hydraulic fluid pressure on downstrokes. At the same time, the outlet check valves open when the hydraulic pressure in the pump exceeds the pressure in the system after the pump.

A hydraulic seal is one of the few parts that wear out. Basically, it prevents fluid from flowing into the actuator while the hydraulic piston is moving back and forth. Seal specifications are determined by the fluid, its pressure and temperature. Most Haskel pumps can be operated without contamination by use of a vent or distance piece between the pump section and the air drive.

A gear pump is a type of positive displacement (PD) pump. Gear pumps use the actions of rotating cogs or gears to transfer fluids. The rotating gears develop a liquid seal with the pump casing and create suction at the pump inlet. Fluid, drawn into the pump, is enclosed within the teeth of the rotating gears and transferred to the discharge. A gear pump delivers a smooth pulse-free flow proportional to the rotational speed of its gears.

There are two basic designs of gear pump: external and internal (Figure 1). An external gear pump consists of two identical, interlocking gears supported by separate shafts. An internal gear pump operates on the same principle but the two interlocking gears are of different sizes with one rotating inside the other. The larger gear (the rotor) is an internal gear i.e. it has the teeth projecting on the inside. Within this is a smaller external gear (the idler – only the rotor is driven) mounted off-centre. This is designed to interlock with the rotor such that the gear teeth engage at one point. A pinion and bushing attached to the pump casing holds the idler in position. A fixed crescent-shaped partition or spacer fills the void created by the off-centre mounting position of the idler and acts as a seal between the inlet and outlet ports.

As the gears come out of mesh on the inlet side of the pump, they create an expanded volume. Liquid flows into the cavities and is trapped by the gear teeth as the gears continue to rotate against the pump casing and partition.

Close tolerances between the gears and the casing allow the pump to develop suction at the inlet and prevent fluid from leaking back from the discharge side (although leakage is more likely with low viscosity liquids).

Gear pumps are compact and simple with a limited number of moving parts. Gear pumps are unable to match the pressure generated by reciprocating pumps or the flow rates of centrifugal pumps but offer higher pressures and throughputs than vane or lobe pumps. Internal gear pumps have better suction capabilities than external gear designs and are more suited to high viscosity fluids, although they have a useful operating range from 1cP to over 1,000,000cP.

Since output is directly proportional to rotational speed, internal gear pumps are commonly used for metering and blending operations. The low internal volume provides for a reliable measure of liquid passing through a pump and hence accurate flow control.

Internal gear pumps can be engineered to handle aggressive liquids. While they are commonly made from cast iron or stainless steel, new alloys and composites allow the pumps to handle corrosive liquids such as sulphuric acid, sodium hypochlorite, ferric chloride and sodium hydroxide.

Internal gear pumps are self-priming and can dry-lift although their priming characteristics improve if the gears are wetted. The gears need to be lubricated by the pumped fluid and should not be run dry for prolonged periods. Some gear pump designs can be run in either direction so the same pump can be used to load and unload a vessel, for example.

The close tolerances between the gears and casing mean that these types of pump are susceptible to wear particularly when used with abrasive fluids or feeds containing entrained solids. External gear pumps have four bearings in the pumped medium, and tight tolerances, so are less suited than internal gear designs to handling abrasive fluids. For these applications, internal gear pumps are more robust having only one bearing (sometimes two) running in the fluid. A gear pump should always have a strainer installed on the suction side to protect it from large, potentially damaging, solids.

Generally, if the pump is expected to handle abrasive solids it is advisable to select a pump with a higher capacity so it can be operated at lower speeds to reduce wear. However, it should be borne in mind that the volumetric efficiency of a gear pump is reduced at lower speeds and flow rates. A gear pump should not be operated too far from its recommended speed.

For high temperature applications, it is important to ensure that the operating temperature range is compatible with the pump specification. Thermal expansion of the casing and gears reduces clearances within a pump and this can also lead to increased wear, and in extreme cases, pump failure.

Despite the best precautions, gear pumps generally succumb to wear of the gears, casing and bearings over time. As clearances increase, there is a gradual reduction in efficiency and increase in flow slip: leakage of the pumped fluid from the discharge back to the suction side. Flow slip is proportional to the cube of the clearances between the cog teeth and casing so, in practice, wear has a small effect until a critical point is reached, from which performance degrades rapidly.

Gear pumps continue to pump against a back pressure and, if subjected to a downstream blockage will continue to pressurise the system until the pump, pipework or other equipment fails. Although most gear pumps are equipped with relief valves for this reason, it is always advisable to fit relief valves elsewhere in the system to protect downstream equipment.

The lower speeds, greater clearances and higher internal volumes of internal gear pumps make them more suitable for shear-sensitive liquids such as foodstuffs, paint and soaps than external gear designs. Internal gear pumps are also preferred when hygiene is important because of their mechanical simplicity and the fact that they are easy to strip down, clean and reassemble.

Internal gear pumps are versatile with an effective operating viscosity range of 1cP to 1,000,000cP. They are often used on thin liquids such as water, solvents and fuel oil but excel at pumping thick liquids such as asphalt, chocolate, and adhesives. Internal gear pumps also have a wide operating temperature range (up to 400°C) making them suitable for pumping difficult fluids such as tar and molten sulphur.

An internal gear pump moves a fluid by repeatedly enclosing a fixed volume within interlocking gears, transferring it mechanically to deliver a smooth pulse-free flow proportional to the rotational speed of its gears.

Internal gear pumps are versatile, being capable of operating across a wide range of fluid viscosities and temperatures. They are preferred to external gear designs in applications involving higher viscosity fluids, at high temperatures and with fluids containing solids. Typically, internal gear designs operate at lower rotational speeds than external gear designs, have greater clearances and are therefore less susceptible to wear in these applications. For the same reasons, internal gear pumps are also better suited to pumping shear-sensitive fluids.

Last week I wrote up a review for Axe & Sledge’s latest product, “Home Made.” Today I present “Hydraulic,” which is Axe & Sledge’s non-stim and supreme pump pre-workout.

HYDRAULIC is the first non-stimulant pre-workout of its kind. BLOOD FLOW = NUTRIENT FLOW = GROWTH HYDRAULIC is the first stimulant free pre-workout of its kind. A pre-workout formula free of any stimulants that you can actually FEEL! Get the blood...

Formerly known as “Fuel Pump,” Seth and Pat decided to change the name of their premier pump product to “Hydraulic.” It contains 5 patented ingredients: (1) AgmaMax, (2) Creatine MagnaPower, (3) GlycerPump, (4) NitroSigine, and (5) CarnoSyn. Hydraulic doubles as a nootropic, to give it more than just a “pump” benefit.

Hydraulic is a two scooper product, with twenty servings.It is important to remember that the recommended serving size is two scoops, so it could be doubled to forty servings, if only using a signle scoop serving. If someone is utilizing some other pump products (nitrates for example), perhaps a single scoop would be sufficient, to offer a wide range of pump enhancing ingredients, as Hydraulic does not contain nitrates.

We already know that Citrulline is the body’s precursor to arginine, the amino acid molecule responsible for stimulating increases in nitric oxide production. This is important for most pres, as vasodialtion of blood vessels is critical for superior pumps and vascularity due to increased blood flow.

This is where Hydraulic shines. GlycerPump is a high-yield version of standard glycerol (65%) For the record, standard glycerol sucks and yields closer to 30% and as low as 15%, in addition to having horrendous water-solubility. A high-yield amount of Glycerol will super-swell the muscle cells, assuming the body is sufficiently hydrated. GlycerPump focuses less on vasodialtion and blood flow and more so with saturating the muscle tissue with fluid - and it does so incredibly fast. Add in some carbs and a good GDA, and GlycerPump super-compensates the muscle swelling effect.

*Personal note - I ran an experiment for my last show, where although I was dehydrated on show day, I added a scoop of Hydraulic to my gatorade 20min before walking on stage. This filled my muscle tissue out incredibly well and left no subcutaneous water. It truly drives liquid where you want it - into the muscle cells and not BETWEEN the muscle tissue and the skin.

I won’t delve too deep here. We all know Taurine acts as a hydration booster and endurance boosting ingredient. 2000mg is the clinciall proven dose and Hydraulic delivers just that. This is a great compliment to GlycerPump.

I am a fan of this addition, but not necessarily for the creatine… Creatine MagnaPower is a chelated magnesium creatine (from Albion Human Nutrition). When creatine and magnesium are chelated, the end result is higher bioavailability. So why doesn’t every company chelate ingredients or minerals? Honestly, because it is too expensive. I am a proponent of this addition of MagnaPower, because it yields 30% of one’s recommended daily dose of magnesium. For numerous reasons, this is an extremely important mineral that not many people are getting their sufficient daily amount. Don’t take Hydraulic if you think it will supplement your cretine needs. Although chelated, you still would need another two grams minimum of creatine to hit your daily requirement.

AgmaMax is a patented form of Agmatine Sulfate. Essentially, once Arginine levels are high in the body, the body begins to produce an enzyme known Arginase, to buffer and reduce the amount of Agamatine in the body. If we want prolonged pumps, we want to hinder this enzyme as long as possible. AgmaMax does just that, by acting as an inhibitor of Arginase, plain and simple. AgmaMax gives you longer pumps, so you can workout longer or go hit the poolside whilst still maintaining your pump.

This is my second favorite pump ingredient. Nitrosigine is inositol arginine silicate, and is far superior than simple arginine at boosting nitric oxide within the body.*1 I’ll cite to my source below, but Nitrosigine has been shown to produce and maintain nitric oxcide levels in the body for as long as two weeks after supplementing with the ingredient And maintaining a minimum 500mg dose during that time. Nitrosigine is a skin ripping pump ingredient and I love it.

I love every single ingredient here (not even mentioned the B vitamins). If there is anything I could change, I might opt to add some nitrates. The synergy between Nitrosigine and some NO3-T is incredible. I have added some vasoblitz to this for training and it results in the most full muscle pumps/contractions I have ever had. Seriously, the skin gets too tight on leg day or arm day. The Tyrosine is enough to give me mental acuity and focus and the CarnoSyn gives me the endurance to handle some triple drop sets.

Rocket Pop gives you what you would expect: Raspberry, Cherry, and Lime. Hydraulic is not overly sweet.You can really taste each flavor without being tricked by the high levels of sucralose.

The soluability is superb. If standard Glycerol was used in lieu of GlycerPump, this product would be clumpy and have little chunks floating at the top. As the picture shows, this is minimal fizz and foam.

Hydraulic crashed my top five preworkout ranking. I am a huge fan of the Nitrosigine and GlycerPump combo. The pumps are insane and the product stacks well with any other preworkout you could want. The effects are staggering and prolonged, thanks to AgmaMax. The multi-functional uses for this product (can be standalone product or stacked with stims) are perfect, and gives you options for any type of training you do, or the time of day you train.

Hydraulic is my go-to for arm day and shoulder day as a standalone, and stacked alongside some stims for the heavy and larger muscle groups. Fair warning - the pumps are real. If you are someone like me, who can’t handle crazy pumps on leg day, be warned, and maybe consider using a single scoop versus two on that day.

If you like pumps, try this product. Message for discount code! I will send out a two samples of Hydraulic. Just comment and let me know your current favorite pump pre-workout product!
