Pumps for Use with Special Fluids: Water Glycol, Calibration Fluids, Skydrol

Hydraulic pumps for applications using water based and fire resistant fluids

Hydraulic Pumps for Water-Based,
Fire-Resistant and Other Special Fluids

Dynex provides pumps for use with special fluids including a variety of water-based, fire resistant and others. The properties of these special fluids include a combination of high or low viscosity with either high or low lubricity.

Various pump models are available for use with water glycol, Viscor and other diesel calibration fluids, Skydrol and other phosphate ester fluids, machining coolant, brake fluid, and various military fluids.

Dynex high-pressure pumps are used in the production process for biodiesel fuel, including various transesterification refinery processes. These pumps can operate at pressures to 8000 psi (560 bar) with various vegetable oils.

Dynex hydraulic pumps operate within a wide range of recommended viscosities from 31.6 to 3,142 SUS (1,5 to 680 cSt).

Special fluid applications include:

Wellhead Safety Control Systems
Blowout Preventer (BOP) Systems
Diesel Calibration Testing
Biodiesel Fuel Production
Hydrostatic Roll Balance Systems
Lubrication Systems
Hydraulic Test-Stands
Ground Support Equipment
Industrial Coolant Supply Systems
Hydroform Presses

Pumps for water glycol, diesel calibration fluid and skydrol

Dynex pump models are available for use with water glycol, Skydrol and other phosphate ester fluids, Viscor and other diesel calibration fluids, and various military fluids.

Pumps designed for low lubricity and low viscosity fluids

Checkball pumps feature a single fluid design, with internal bearing lubrication provided by the pumped fluid. This design eliminates the potential for cross contamination, which may occur in other pump designs requiring a secondary fluid for lubrication.

Fluid Compatibility List

Various pump models are compatible with a variety of special fluids. Because many conditions affect successful operation, contact the Dynex sales department for a review of your application using any of these special fluids.
