water glycol hydraulic pump price
Self-priming up to 6 ft., these pumps have a stainless steel housing sealed with PTFE to resist chemicals such as ammonia and detergents as well as harsh solvents including methyl ethyl ketone (MEK).
Continental Hydraulics announced that it’s PVX vane pumps are now fire-resistant, as they are approved for water glycol to 2,500 psi. Water glycol fluids have proven to be an excellent fire-resistant hydraulic fluid option. This should open up new markets like food processing, steel manufacturing, automotive assembly or and other industry that typically use the water glycol fluids.
Glycol pumps are available in a variety of sizes, including one piston, hydraulic piston pumps, and hydraulic piston pumps. The number of different glycol pumps is available in the form of a piston, and the piston is one of the hydraulic piston pumps. The number of pressure glycol pumps vary depending on the pressure of the glycol pump, as they are made with two-stage engines. The pressure of the glycol pumps varies depending on the type of glycol pump, and the one that is used by either a piston or hydraulic piston pumps. The number of glycol pumps vary depending on the pressure of the pump, for they are low-pressure, and semi-automatic.
It can be used as a water-operated glycol pump, in the form of a water-operated glycol pump, which is normally used as distilled water glycol bottles or water glycol bottles. A second hand glycol pump is also called the iston piston pump, which is a type of water-operated glycol pump. The iston piston pump is another type of pump with air pressure.
The type of glycol pump vary depending on its usage. For instance, the glycol water pump may vary depending on its usage. Glycol pumps are ideal water pumps for large-capacity pumping, and as a name, glycol pumps vary depending on their usage. As electric glycol pumps are ideal water pumps for large-capacity water, as they are low-pressure, and as a full-fluid pump. A electric glycol pump may vary depending on their usage, among the different types of pumps. The electric power pumps are ideal water pumps for large-capacity work, as they are more portable and can be used on pumps. A high-pressure glycol pump are ideal water pumps for electric work, and as a name replacement, a glycol pump may vary depending on its usage.
Glycol piston pumps are varying in terms of their usage. The piston pump is typically one of the hydraulic piston pumps, since they are low onpressure, and are one of the most used for this purpose. A piston pump is a type of hydraulic piston, and it also has a low-pressure connection.
The 1.7Kw type SMW hydraulic pump is specifically designed for water-based fluids. Separation of the lubricating oil and the pumped fluid is achieved by the installation of a cavity between the cylinder block and the case. Bypass from the pistons is collected in this cavity and returned to the inlet side of the pump. The SMW pump incorporates three, four or six axial pistons actuated by a single rotating swash plate.
Rotation is bi-directional and the pump may be mounted horizontally or vertically. Vertical motor pump units are supplied with a bellhousing and coupling. Horizontal units have the option of direct coupling between the pump and motors from 71 to 90 frame size.
A suction filter of 150 microns or better should be used. Finer filtration is desirable for the pump life, but is important that the inlet flowrate to the pump is not restricted and no more than -2 in.Hg is measured in the suction pipework under pumping conditions. Where possible a positive pressure should be maintained in the suction pipework under flowing conditions. When the pump is stationary the suction line should be kept under positive pressure to allow priming.
Important - pumps are delivered from Marshalsea with the case lubricating oil drained. Before the pumps are used, the case should be filled with Castrol Alphasyn PG150 to the level specified on the pump technical data sheet
Glycols are an excellent liquid for use with cooling, heating and protective purposes. They are often mixed with water to provide protection against freezing for example in engine cooling applications, as a heat transfer medium and also for maintaining the existing temperatures of a system. They are used as an ingredient for varnishes, paints, polish, ink, cosmetics polyurethane and polyethylene. Glycol has a relatively low Specific Gravity and viscosity meaning it can be handled with centrifugal pumps.
Glycols are inexpensive due to them being inert and having broad chemical compatibility it allows cheap accessible materials such as cast iron to be used in closed-loop cooling systems. Seawater or brine can be used in cooling applications but means more expensive materials must be used as such liquids are aggressive.
They are used in particular in non-moving hydraulics (e.g. machine tools, presses, etc.) and in vehicles that operate in a confined space (electric forklifts, etc.).

Hydraulic fluid performance, including water-glycols (W/G), depends on the chemical composition of the fluid and cleanliness. This article presents an overview of the effect of W/G fluid chemistry on pump wear. An overview of recommended analytical procedures to assure adequate long-term hydraulic and lubrication performance is provided. These procedures can result in substantial improvements in hydraulic pump longevity and performance.
Many industrial applications such as steel making, die casting, etc. require the use of hydraulic fluids that offer greater fire safety than that achievable with mineral oil. One of the most common alternatives to mineral oil for use in these applications is a water-glycol hydraulic fluid.
The performance of all hydraulic fluids, including W/G hydraulic fluids, depends on the composition of the fluid and on fluid cleanliness. Although there are numerous references describing analysis procedures for petroleum oil-derived hydraulic fluid, similar references describing the analysis of water-glycol hydraulic fluid are relatively rare.
Water-glycol hydraulic fluid formulations typically contain water (for fire protection), glycol (for freeze point protection), polyalkylene glycol (PAG) thickener, an additive package to provide corrosion and antiwear protection, antifoam/air release additive and dye for leak detection.
The performance of a hydraulic fluid depends on the particular additive and concentration used in the formulation. Substances that exhibit a marked effect on hydraulic pump wear, according to the ASTM D2882 test, are water, amines and antiwear additives. The ASTM D2882 test is conducted at 2,000 psi (13.8 MPa) for 100 hours and eight gallons per minute (30.6 L/min) in a Sperry Vickers V-104C vane pump.
Water content creates one of the most significant influences on hydraulic pump wear rate. Figure 1 shows that wear rates increase with increasing water content. Thus, it is critically important to control the water content of W/G hydraulic fluids if both fire-resistance and antiwear performance is to be maintained.
The primary function of the amine is to provide corrosion protection. Vapor and liquid phase inhibitory properties of an amine can be determined using the 200-hour Corrosion Test. This test is conducted by aerating the heated hydraulic fluid at 70 ± 2°C in contact with metal test coupons for 200 hours. The test coupons that are immersed in the fluid are: steel (SAE-1010, low carbon), cast aluminum (SAE-329), copper (CA-110) and brass (SAE-70C). Vapor phase corrosion effects are also determined using coupons of cast iron (G-3500) and steel (SAE-1010) which are suspended above the solution. Figure 3 illustrates a typical corrosion test cell.
Figure 3. Corrosion Test Apparatus is Convenient for Corrosion-Inhibitor Studies of Water-Glycol Hydraulic Fluids Under Laboratory Conditions. Immersed Metal Specimens are Separated by a Glass “Z-bar” in the Specific Order Shown. Vapor-Space Test Specimens are Hung from the Top of the Glass Test Cell. Fluid Temperature is Monitored with an Immersion Thermometer, Air is Blown into the Mixture Using an Aeration Tube, and a Cold-Water Condenser is Used to Reduce Fluid by Evaporation.
Fortunately, as shown in Figure 4, it is possible to formulate a W/G hydraulic fluid so that there will be minimal impact on wear with the inevitable loss of additive over time. Nevertheless, once the critical level is achieved there is a dramatic increase in wear rates with further decreases in antiwear additive concentration.
Hydraulic pump lubrication depends not only on fluid chemistry but also on both liquid and solid contamination. In W/G fluids, the most common liquid contamination is usually petroleum oils, which may enter the hydraulic system from numerous sources. Because petroleum oils are insoluble in the W/G they may be simply skimmed from the fluid reservoir. In practice, removal is often neglected for long enough periods that some of the additives adsorb into the mineral oil and are removed from the working fluid when that oil is skimmed from the surface of the reservoir. Every effort should be made to prevent this form of contamination.
Water contained in a W/G fluid can be lost through evaporation during normal hydraulic operation. Water loss increases the fluid’s viscosity. Water must therefore be added back to the system to maintain fire-resistance and to assure proper viscosity and system operation.
The most common methods for determining water content of a W/G hydraulic fluid are refractive index, viscosity and Karl Fischer analysis. Refractive index is the most commonly used and is readily determined using a portable temperature-compensated refractometer that provides readings in degrees Brix.
The principal limitation of water determination by refractive index is that refractive index is affected by any material, including contaminants, that may be present in the hydraulic fluid. Thus, it is advisable to crosscheck water analyses obtained by refractive index against at least one other analytical method. After the water concentration is determined, additional water should be added if necessary. Some suppliers provide tables such as Table 1, which provide water make-up levels without the use of the calibration plot represented by Figure 5.
Only distilled or deionized water with a conductance of less than 15 µmhos/cm (or a maximum total water hardness of 5 ppm has also been recommended), should be added to a W/G hydraulic fluid system. This is critically important because polyvalent metal ions such as Ca+2, Mg+2, Mn+2, etc. will react with the antiwear additive, usually an organic carboxylic acid, to form a polyelectrolyte complex salt (Formula 1) which appears as a white, soapy solid. This process must be prevented for two reasons. The first is that it will lead to continuous depletion of the critically important antiwear additive. Second, the presence of such precipitates, like any solid material, will increase wear.
The water content of a hydraulic fluid may also be determined by viscosity measurement. One common method of viscosity measurement is to follow the ASTM D445 procedure for kinematic viscosity.
By using the chart in Figure 6, viscosity vs. water content, the amount of water can be easily maintained within the necessary range for the fluid. Alternatively, a water make-up table based on viscosity, as shown in Table 2, may be obtained from the W/G hydraulic fluid supplier for the specific fluid being used.
The load-bearing capacity of a fluid film depends on fluid viscosity. Oxidative and thermal degradation processes will result in a decrease of fluid viscosity. Thus routine viscosity measurement is one of the best methods of monitoring fluid stability. However, such comparative measurements must be made at the same total water content.
The third, and most unambiguous, method of water determination is by Karl Fischer Titration (ASTM D1744). The advantage of Karl Fischer analysis is that it is a direct measure of water content, while viscosity and refractive index are both indirect measurements which are substantially affected by either contamination (refractive index) or fluid degradation (viscosity).
Amine concentration in a W/G hydraulic fluid is designated as reserve alkalinity and is conventionally reported as the volume in milliliters of 0.1N hydrochloric acid (HCl) required to titrate 100 ml of W/G fluid to pH 5.5. A typical titration plot is shown in Figure 7.

It has thus far been shown that hydraulic fluid quality and performance depends on fluid cleanliness and chemistry variation. On occasion, it is necessary to troubleshoot fluid performance in malfunctioning systems. In addition to the chemical and physical analyses described, it is often valuable to analyze any wear debris. Ferrography is one of the principal wear debris analysis methods. It can be used to determine the concentration and distribution of wear particles contained in the hydraulic fluid.
It has been shown that W/G hydraulic fluid performance, like all other hydraulic fluids, depends on both fluid cleanliness and fluid formulation chemistry.
Water, antiwear additive and corrosion inhibitor concentrations must be monitored to assure optimum fluid antiwear performance. Recommended analytical methods include:
While analysis by ion chromatography and ferrography are specialized procedures and may be conducted as required, analysis for water content, reserve alkalinity, viscosity as well as visual observations are critical and must be conducted regularly (usually by the fluid supplier).
If the hydraulic system is properly maintained and fluid performance is adequately monitored, excellent long-life hydraulic and lubrication performance with water-glycol fluids is achievable.

Using fire-resistant lubricants is a cost-effective option compared with installing mechanical fire-suppression equipment. With a 42–44% water content, Shell Water-Glycol S2 CX is an HFC type, fire-resistant hydraulic fluid designed for use in industrial equipment operating in areas subject to fire hazards, including in the steel, aluminium, die-casting, mining, glass and tunnel boring industries. It has a higher ignition temperature and lower flammability than mineral oils, and its glycol (diethylene glycol) content enables the fluid to be used in all seasons.
The fluid uses an innovative friction modifier to provide excellent pump lubricity, which can help to extend equipment service life and reduce maintenance costs. In the Vickers V-104 vane pump test, only 10–15 mg of wear was recorded after 100 hours at 2,000 psi and 65°C (ASTM D7043).
Featuring a high level of anti-wear protection, Shell Water-Glycol S2 CX is engineered to offer increased resistance to mechanical shear and has a stable viscosity that helps to protect components against wear.
Provides corrosion protection to a wide variety of metals, including aluminium, copper, brass, cast iron, steel and others commonly used in hydraulic systems.
Water based hydraulic systems have been traditionally used in underground mining applications and in the high temperature areas of steel mills and foundries
abstractNote = {Work is currently underway within the ASTM D.02 N.07 Hydraulic Fluid Testing Committee to evaluate the potential of replacing the Vickers V-104 vane pump with a newer, more current model 20VQ vane pump for use in an updated ASTM D-2882 and other national standards. All of the round robin work conducted within the committee thus far has involved the use of non-aqueous hydraulic oils. Although there are some significant inter-laboratory reproducibility problems, it appears that the overall ranking of the hydraulic oils by most laboratories appears to be consistent. To further evaluate the potential utility of replacing the Vickers V-104 pump with the 20VQ pump, a series of different water-glycol hydraulic fluid formulations with significantly different wear rates were evaluated using a modified ASTM D-2882 testing procedure. The results showed that expected catastrophic pump failures, which occurred with the V-104 pump, not only did not occur with the 20VQ pump, but the relative orders of wear rates for some of the fluids were also different. In this paper, a brief history of the development of the ASTM D-2882 test, as currently conducted, will be presented, a comparison of the features of the V-104 and 20VQ pump and cartridge assemblies will be given and a comparative tabulation of the pump test using the V-104 pump and the 20VQ pump using different testing conditions will be provided. Finally, recommendations for future work will be made.},
With hundred of different hydraulic fluids available, it is often difficult to decioher which is best for your operation. Discover the hazardous properties, ISO 9001:2015 compliance, fire-resistance, and more of the glycol and water-based hydraulic fluids below.
Glycol-based hydraulic fluids are commonly found in industries such as die-cast manufacturing operations that operate at high temperatures, due to their low cost and good lubricating properties. Even in a low-heat environment where the flashpoint may not come into play, leaks from machines cause a concern. Most hydraulic fluids are hazardous to the environment and, if introduced into the groundwater, can expose a business to substantial contamination fines.
If your glycol-based hydraulic fluid is not disposed of properly — accidentally or intentionally — you will face large fines from the EPA and local governments. Violations to the Clean Water Act can be levied up to $25,000 per day until the spill is cleaned up. In addition, you will be required to pay for cleanup costs and be exposed to an increase in insurance premiums.
Non-hazardous water-based hydraulic fluids can eliminate all of these risks for your company, while complying with the risk-based thinking for ISO 9001:2015. Implementing a water-based hydraulic fluid meets the requirement of mitigating points of risk for your business. Composed of naturally occurring components, water-based is non-hazardous in nature, eliminating the need for costly cleanup if introduced into the groundwater.
When your business is consistently operating at high temperatures, with potential for fires, it is important that your hydraulic fluid can keep up without the risk of fire ignition. Glycol-based fluids have a fairly low operating range of -30° to 150°C. Under high heat and pressure, where a failure in a line can produce a spray, a glycol-based fluid can present serious hazards.
Our non-hazardous water-based solutions are better suited for industries that run at high temperatures with risks for fire, due to their exceptional flashpoint that runs >350⁰ C. This is much higher than most glycol fluids. Keeping employees safe and producing a quality product should not be a trade-off.

A large automotive components manufacturer had a series of fires on its hot stamping lines—all caused by oil from ruptured hoses or leaky couplings that ignited when the oil came into contact with the hot metal being formed. In 2012, a particularly bad fire injured workers and caused 12 days of downtime, resulting in £5.3 million in damages from lost production and repairs. After assessing all the options—including changes to the sprinkler systems and equipment design—management concluded the safest and most cost-effective approach would be to replace the highly flammable mineral oil with a synthetic, water-free hydraulic fluid (HFD-U). This conversion was a significant outlay—approximately £70,000. So why did management believe avoiding future fires was worth that much additional expense?
Today, in manufacturing operations that pose a risk for fire or explosion, most large-scale manufacturers have already replaced mineral oil with fire-resistant hydraulic fluids. Even though these fluids can cost anywhere from two to four times as much as mineral oil, the economics are sound for these producers because with mineral oil, there is simply too much at risk.
Many manufacturers are experiencing a weakened economic environment. So discussions on spending more on anything, including fire-resistant hydraulic fluids, are usually not at the top of anyone’s list…unless there is a fire.
A fire can be devastating to a producer, and even more so in these difficult times. Waiting until there is a fire to review fluid options is not a wise choice. And because the economics, regulations, and technologies related to hydraulic fluids are always changing, it’s best to evaluate hydraulic fluids periodically, reviewing all the issues to determine if converting to a fire-resistant fluid makes sense for the facility.
Globally, there are two types of fire-resistant hydraulic fluids that are dominant in high-temperature operating environments: water glycols (HFC) and polyol ester (HFD-U)-based fluids. The relative benefits of each technology are different for each situation. Every company, every facility has a different set of demands to respond to—demands placed by regulators, customers, and the economy.
When evaluating hydraulic fluid options, it is important for the manufacturer to pull together an internal team of stakeholders so all business issues can be considered and brainstormed. Within some companies, silos develop that impede the right overall decision. Each department has a specific focus, such as
We check out the wastewater: the geographic location and proximity to metro area. We then proceed to onsite or outside, regulations, and current costs/surcharges.
We analyze conversion. This can be from mineral oil to water glycol, which is a longer process, involving draining, flushing, and refilling. The mineral oil to HDF-U conversion is a shorter process of topping off, draining, and refilling. There is no need to flush the system.
