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)

- 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
