ORLITA® DR Rotating Plunger Pump


High Accuracy Metering

The ProMinent® Orlita® DR is a valveless rotary piston metering pump capable of reaching pressures up to 5,800 psi (400 bar) and flows up to 1,090 gph (4,125 l/h). Fluid is pumped by the combined oscilating and rotating movement of the piston. The valveless design allows accurate metering of highly viscous media up to 1,000,000 cPs.

The DR can also handle fluids containing solids as the slotted piston and the valveless technology allow for solids to move through the pump unobstructed.
