Reciprocating Pump Model DP-DE

Oilgear Model DP-DE Pumps are capable of delivering discharge pressure up to 135,000 PSI. The discharge pressure is in direct proportion to input air pressure and is controlled accurately by a regulator in the input air line. When a selected discharge pressure is achieved the pump maintains the pressure and volume unattended. Standard pumps are designed for continuous operating discharge pressures. Model 'DP-DE' Pumps are double powered and have a 4' stroke. Power pistons are furnished in 8" or 10" diameters. A wide range of plunger diameters is available. Refer to operating data chart for plunger diameters. Air is used as the powering medium at pressures from 100 to 125 PSI.
