The Prominent ORLITA DR Plunger Metering Pump is a high-performance pump that is designed for the precise metering of high-viscosity and extremely high-viscosity media, even containing solid fractions. The pump can be operated within a broad stroke rate range due to its operation without valves. 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.

 

Your benefits

1. Low-wear and precise operation even at high pressures thanks to the rotary piston with abrasion-resistant / wear-resistant surface coating
2. Pumping direction can be selected depending on the fitting position of the piston
3. A reverse suction effect can be set in a continuously variable manner by rotating the pump head around its longitudinal axis
4. Drive configuration ideal for installation in any position (vertical or horizontal)
5. The weight of the ORLITA DR Plunger Metering Pump can range from 150 to 1500 kg, and power can range from 0.75 to 7.5 kw.

 

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
