Plunger Metering Pump ORLITA DR

Capacity range of single-head pump: 0 – 2000 l/h, 400 – 5 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 -40 °C to 400 °C.

Product description

For the precise metering of high-viscosity and extremely high-viscosity media even containing solid fractions

ORLITA DR plunger metering pumps (DR 15 to DR 150) are special pumps for high-viscosity and extremely high-viscosity media, which can also contain solids. The pump can be operated within a broad stroke rate range due to its operation without valves.

Your benefits

Optimum adaptation to processes with high-viscosity and extremely high-viscosity media, even 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 - 40 °C to + 400 °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
  • Drive configuration ideal for installation in any position (vertical or horizontal)

Field of application

  • Metering of high-viscosity and extremely high-viscosity media containing solid fractions.

    Technical Details

    • DR 15 - stroke length: 0-15 mm, Rod force: 1,800 N
    • DR 150 - stroke length: 0-32 mm, Rod force: 15,000 N
    • Stroke length adjustment range: 0 – 100% in operation and idle
    • Stroke length adjustment: manually by means of a manual adjustment wheel and scaled display (optionally with electric actuator or control drive)
    • Metering reproducibility is better than ± 0.5% within the stroke length adjustment range of 10 to 100% under defined conditions and with proper installation
    • Wetted materials: Stainless steel, special designs are available on request
    • A wide range of drive versions is available: Three-phase AC standard motors, motors for use in areas at risk from explosion and different flange designs for use in customer-specific motors
    • Degree of protection: IP 55
    • Temperature range - 40 °C to + 400 °C
    • The play between the piston and cylinder responsible for the sealing effect is selected depending on the viscosity
    • Turret on the rear head end, either designed as a circular collecting vessel for leaks or exposed to a sealing medium
    • The turret is sealed by elastomer lip sealing rings
