ORLITA DR Rotating Plunger Pump

Capacity range of single-head pump: 0 – 273 l/h, 400 – 76 bar

The plunger metering pump ORLITA DR does not need valves and can therefore be operated within a broad stroke rate range. It is therefore suitable for use with high-viscosity and extremely high-viscosity media of up to 106 mPas within a wide temperature range of -30 °C to +200 °C.

Product description

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 oscillating 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.

Your benefits

Optimum adaptation to processes with high-viscosity and extremely high-viscosity media, even those containing solid fractions:

  • Low-wear and precise operation even at high pressures thanks to the rotary piston with abrasion-resistant / wear-resistant surface coating
  • Valve-free operation guarantees a broad stroke rate range
  • Wide range of uses: Operating pressure of up to 400 bar, temperature range of -30°C to +200°C
  • Pumping direction can be selected depending on the fitting position of the piston
  • A reverse suction effect can be set in a continuously variable manner by rotating the pump head around its longitudinal axis
  • Power end configuration ideal for installation in any position (vertical or horizontal)
  • Excellent hydraulic efficiency
  • 2 different gear ratios are available
  • Customised designs are available on request
