Pumps for Special Fluids

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

The checkball pump’s ability to operate with a combination of high or low viscosity and with either high or low lubricity fluids offers remarkable flexibility. Dynex hydraulic pumps operate within a wide range of recommended viscosities from 31.6 to 3,142 SUS (1,5 to 680 cSt). Dynex water glycol pumps are widely used in the offshore oil & gas industry.

Pumps for Aerospace Testing

Dynex checkball pumps provide exceptional performance in the harsh conditions required for testing aerospace components. Pumps operate at pressures to 20,000 psi, using a wide range of phosphate ester fluids, and various MIL-SPEC fluids.

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. This is a partial list which is updated regularly. Not all compatible fluids are shown here.
