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.
