Self-priming centrifugal pumps are unique. As the name suggests, they have the ability to prime themselves under suction lift conditions. They draw fluid up from tanks or pits below, making them easier and safer to work on than those that work below ground. Under the right conditions, they’ll free themselves of entrained gas and function normally on their own, but sometimes, they can’t.

A BRIEF NOTE OF CAUTION:Just because self-priming pumps able to pull fluid into them, doesn’t mean that they should start up dry. Self-priming, centrifugal pumps need fluid in the casing to get started. Running dry, even for a short while, will cause damage to the mechanical seal, and pump failure.

Once the pump is turned on, the impeller begins to turn in a counter clockwise rotation. The fluid inside, or the “initial prime”, flows through the volute into the discharge cavity. Here, the air and fluid separate, the air evacuates through an open ended line, or air release line, while the fluid returns to the impeller through a recirculation port.

As fluid moves up the suction line, the air ahead of the fluid is pushed into the casing and handled as the initial prime was handled through the recirculation process. Once the fluid arrives in the pump, it operates as normal.

As fluid recirculates in the pump and forces air out of the discharge chamber, it’s trying to create an area of low pressure. However, if there’s a leak in the suction line, air continues to be drawn into the pump, never allowing it to release enough to create that area of low pressure.

If a valve on the air release line is closed, and the valve on the discharge line is closed, again, it"s giving no place for the air to go and get out of the pump.

If there is excessive clearance between the impeller and the wear plate, the pump has a difficult time creating a low-pressure area. This is typically caused by wear, but could also be due to improper reassembly.

If you’ve undersized the pump for the suction line, it will not be able to create the low-pressure area it needs to prime. It’s important to understand the suction lift requirements before selecting a pump for the application. Use Gorman-Rupp’s Pump Selection Guide for the calculations you’ll need.

The ability for self-priming pumps to prime hinges on all the right conditions. The pump must be able to evacuate air from inside the pump, create a low-pressure area at the eye of the impeller, and also be properly sized for the right NPSHconditions.

When you begin working with hydraulic pump drives, they can be a bit overwhelming. But, it doesn"t have to be that way. Below we will dive into some pump drive basic info and review the key manufacturers.

A hydraulic pump drive(also referred to as a pump drive) is a device that connects a prime mover to a hydraulic pump. There are several different sizes & configurations available. There are also several different input options, which we will go into more detail about later.

The multi-pad pump drives have a gear train in them to drive the pumps and can be a 1:1 ratio or an increasing or decreasing ratio to drive the hydraulic pumps at the optimal RPM while running the engine at its optimal RPM.

There are various terms used in the field for pump drives. If you hear any of the below nicknames, they are likely referring to a hydraulic pump drive.

Hydraulic pump drives are found in various applications, with the most common being marine, cranes, drilling rigs, construction equipment, and agricultural applications. They can power hoists, boom cylinders, outriggers, drill heads, and power the machine through hydraulic motors.

As machines have gotten more complex in recent years, they now need power for multiple actions during use. Therefore, it is much easier to design a system that drives these loads hydraulically than drive the loads mechanically.

That is where the hydraulic pump drive comes into play in various applications. Additionally, pump drives are pretty simple, comprised of a gearbox with an input, bearings, gears, and outputs to mount with the hydraulic pumps.

The simplest pump drive available is a single pump direct drive, consisting of a flex plate and bell housing plate coupled to one hydraulic pump. Pump drives come in a variety of output sizes, going up to five outputs.

There are remote inputs, with the most common being keyed input shafts or flanged input shafts. Lastly, there are clutch inputs, with the most common being a mechanically engaged clutch. Palmer Johnson has the resources to also offer pneumatic or hydraulic engaged clutch inputs for pump drives.

The most common pump drive manufacturers are Funk, Durst, and Twin Disc. All three manufacturers offer a full array of pump drive sizes, ranging from one pad all the way up to a five pad option.

In addition, they all offer an expansive list of input and output options as well as several ratio options that vary depending on the particular pump drive model.

Palmer Johnson is an authorized distributor for Funk, Durst, and Twin Disc with decades of experience supporting these product lines. So whether you need a pump drive for a brand new application or need to replace an existing pump drive that is in use, Palmer Johnson has you covered!

A hydraulic pump converts mechanical energy into fluid power. It"s used in hydraulic systems to perform work, such as lifting heavy loads in excavators or jacks to being used in hydraulic splitters. This article focuses on how hydraulic pumps operate, different types of hydraulic pumps, and their applications.

A hydraulic pump operates on positive displacement, where a confined fluid is subjected to pressure using a reciprocating or rotary action. The pump"s driving force is supplied by a prime mover, such as an electric motor, internal combustion engine, human labor (Figure 1), or compressed air (Figure 2), which drives the impeller, gear (Figure 3), or vane to create a flow of fluid within the pump"s housing.

A hydraulic pump’s mechanical action creates a vacuum at the pump’s inlet, which allows atmospheric pressure to force fluid into the pump. The drawn in fluid creates a vacuum at the inlet chamber, which allows the fluid to then be forced towards the outlet at a high pressure.

Vane pump:Vanes are pushed outwards by centrifugal force and pushed back into the rotor as they move past the pump inlet and outlet, generating fluid flow and pressure.

Piston pump:A piston is moved back and forth within a cylinder, creating chambers of varying size that draw in and compress fluid, generating fluid flow and pressure.

A hydraulic pump"s performance is determined by the size and shape of the pump"s internal chambers, the speed at which the pump operates, and the power supplied to the pump. Hydraulic pumps use an incompressible fluid, usually petroleum oil or a food-safe alternative, as the working fluid. The fluid must have lubrication properties and be able to operate at high temperatures. The type of fluid used may depend on safety requirements, such as fire resistance or food preparation.

Air hydraulic pump:These pumps have a compact design and do not require an external power source. However, a reliable source of compressed air is necessary and is limited by the supply pressure of compressed air.

Electric hydraulic pump:They have a reliable and efficient power source and can be easily integrated into existing systems. However, these pumps require a constant power source, may be affected by power outages, and require additional electrical safety measures. Also, they have a higher upfront cost than other pump types.

Gas-powered hydraulic pump:Gas-powered pumps are portable hydraulic pumps which are easy to use in outdoor and remote environments. However, they are limited by fuel supply, have higher emissions compared to other hydraulic pumps, and the fuel systems require regular maintenance.

Manual hydraulic pump:They are easy to transport and do not require a power source. However, they are limited by the operator’s physical ability, have a lower flow rate than other hydraulic pump types, and may require extra time to complete tasks.

Hydraulic hand pump:Hydraulic hand pumps are suitable for small-scale, and low-pressure applications and typically cost less than hydraulic foot pumps.

Hydraulic foot pump:Hydraulic foot pumps are suitable for heavy-duty and high-pressure applications and require less effort than hydraulic hand pumps.

Hydraulic pumps can be single-acting or double-acting. Single-acting pumps have a single port that hydraulic fluid enters to extend the pump’s cylinder. Double-acting pumps have two ports, one for extending the cylinder and one for retracting the cylinder.

Single-acting:With single-acting hydraulic pumps, the cylinder extends when hydraulic fluid enters it. The cylinder will retract with a spring, with gravity, or from the load.

Double-acting:With double-acting hydraulic pumps, the cylinder retracts when hydraulic fluid enters the top port. The cylinder goes back to its starting position.

Single-acting:Single-acting hydraulic pumps are suitable for simple applications that only need linear movement in one direction. For example, such as lifting an object or pressing a load.

Double-acting:Double-acting hydraulic pumps are for applications that need precise linear movement in two directions, such as elevators and forklifts.

Pressure:Hydraulic gear pumps and hydraulic vane pumps are suitable for low-pressure applications, and hydraulic piston pumps are suitable for high-pressure applications.

Cost:Gear pumps are the least expensive to purchase and maintain, whereas piston pumps are the most expensive. Vane pumps land somewhere between the other two in cost.

Efficiency:Gear pumps are the least efficient. They typically have 80% efficiency, meaning 10 mechanical horsepower turns into 8 hydraulic horsepower. Vane pumps are more efficient than gear pumps, and piston pumps are the most efficient with up to 95% efficiency.

Automotive industry:In the automotive industry, hydraulic pumps are combined with jacks and engine hoists for lifting vehicles, platforms, heavy loads, and pulling engines.

Process and manufacturing:Heavy-duty hydraulic pumps are used for driving and tapping applications, turning heavy valves, tightening, and expanding applications.

Despite the different pump mechanism types in hydraulic pumps, they are categorized based on size (pressure output) and driving force (manual, air, electric, and fuel-powered). There are several parameters to consider while selecting the right hydraulic pump for an application. The most important parameters are described below:

Source of driving force: Is it to be manually operated (by hand or foot), air from a compressor, electrical power, or a fuel engine as a prime mover? Other factors that may affect the driving force type are whether it will be remotely operated or not, speed of operation, and load requirement.

Speed of operation: If it is a manual hydraulic pump, should it be a single-speed or double-speed? How much volume of fluid per handle stroke? When using a powered hydraulic pump, how much volume per minute? Air, gas, and electric-powered hydraulic pumps are useful for high-volume flows.

Portability: Manual hand hydraulic pumps are usually portable but with lower output, while fuel power has high-output pressure but stationary for remote operations in places without electricity. Electric hydraulic pumps can be both mobile and stationary, as well as air hydraulic pumps. Air hydraulic pumps require compressed air at the operation site.

Operating temperature: The application operating temperature can affect the size of the oil reservoir needed, the type of fluid, and the materials used for the pump components. The oil is the operating fluid but also serves as a cooling liquid in heavy-duty hydraulic pumps.

Operating noise: Consider if the environment has a noise requirement. A hydraulic pump with a fuel engine will generate a higher noise than an electric hydraulic pump of the same size.

Spark-free: Should the hydraulic pump be spark-free due to a possible explosive environment? Remember, most operating fluids are derivatives of petroleum oil, but there are spark-free options.

A hydraulic pump transforms mechanical energy into fluid energy. A relatively low amount of input power can turn into a large amount of output power for lifting heavy loads.

A hydraulic pump works by using mechanical energy to pressurize fluid in a closed system. This pressurized fluid is then used to drive machinery such as excavators, presses, and lifts.

A hydraulic ram pump leverages the energy of falling water to move water to a higher height without the usage of external power. It is made up of a valve, a pressure chamber, and inlet and exit pipes.

A water pump moves water from one area to another, whereas a hydraulic pump"s purpose is to overcome a pressure that is dependent on a load, like a heavy car.

Gear pumps are used in a wide range of hydraulic systems; in fact, they are easily among the most common types of pumps seen in this type of equipment. Hydraulic gear pumps are of a fixed displacement design and operate by pumping fluid through a system by means of a prime mover such as an engine or motor.

Gear pumps are used in a wide range of hydraulic systems; in fact, they are easily among the most common types of pumps seen in this type of equipment. Hydraulic gear pumps are of a fixed displacement design and operate by pumping fluid through a system by means of a prime mover such as an engine or motor.

Although there are several uses for gear pumps and significant variations in gear pump components, their basic design and theory of operation is as follows. Every gear pump includes two (sometimes more) rotating gears whose teeth interlock. The rotation of the drive shaft turns the drive gear, which, due to the intermeshing design, also puts the other gear into motion. Hydraulic gear pumps do not create a strong suction so operate best with a flooded inlet.

Internal gear pumps – This types of pump utilises a “gear inside a gear” design. As the gears rotate in the same direction, the space between them varies in a controlled manner, resulting in displacement of the fluid. Internal gear pumps are noted for their relatively quiet operation and ability to manage thick fluid.

External gear pumps – These pumps have two intermeshed gears arranged side by side, one of which is connected to the drive shaft. Rotating the drive shaft creates motion in the gears and creates a flow path on the outside of each gear. An external gear pump can operate effectively at a variety of speeds and with a range of fluid viscosities. The main advantage is simplicity, size to power ratio, price to power ratio.

What can a hydraulic gear pump do that other pumps cannot? For the most part, hydraulic gear pumps offer precise output control that isn’t possible with centrifugal pumps, for example. Increasing or decreasing the speed of the prime mover will increase or decrease the output flow rate. Hydraulic gear pumps are normally made to only run in one rotation however this can normally be changed if required.

Hydraulic internal gear pumps are often more expensive than centrifugal pumps, whilst Hydraulic external gear pumps tend to be less expensive.. They tend to be noisier as well—which can be a problem in environments where extraneous noises cannot be tolerated—and cannot be used to handle abrasive materials.

Engine-driven hydraulic systems have become a staple among truck upfitters. One of the things that most upfitters don"t think about is having to bleed the clutch pump system. Without priming, the risk of cavitation increases, reducing the longevity of your pump.

pumps to perform correctly. There are two types of hydraulic systems: flooded and non-flooded. A flooded hydraulic system is one in which oil flows directly into the pump by gravity, filling the system with oil. A non-flooded system starts with the pump empty of hydraulic oil, requiring suction to pull hydraulic oil through the pump. Below we will discuss a non-flooded hydraulic system.

pump"s lifespan. Deweze has two recommended ways to prime your clutch pump system to prevent pump damage and cavitation. One method involves using pressurized air and a bleeder valve; the other requires filling the suction hose with hydraulic oil.

With the bleeder valve open, wait for the excess air in the system to flow out until there is only hydraulic fluid flowing out of the valve and no air.

goal is to bleed the clutch pump system, not to drain the system. Priming the system with pressurized air and a bleeder valve should be completed; anytime there is air introduced into the clutch pump system. Examples would be the initial installation, reservoir or pump is replaced, or changing the hydraulic fluid. Pumps may need to be reprimed if they make loud noises or you experience delayed movement of hydraulic components.

Fill the suction hose with hydraulic oil until filled. Carefully, without spilling the oil, reinstall the suction hose on the barb fitting and tighten the clamp. At this point, you have primed the pump.
