Plunger pumps
OBL R series pump
Plunger pumps are used for precise dosing and transfer of liquids in industrial processes. They can be used, for example, for dosing chemicals, emulsions, coating materials, oils and other industrial liquids. Our range of plunger pumps also includes models suitable for high-viscosity liquids and liquids handled at elevated temperatures.

R series
The R series is designed primarily for chemical dosing. The flow rate is adjusted by changing the stroke length, and an electric actuator is also available. R series pumps can handle high-viscosity liquids with viscosities of up to 55,000 cP. The maximum liquid temperature is 90 °C. OBL specifies a dosing accuracy of 2% over a 100:1 turndown ratio.
All R series models comply with ATEX requirements. A configuration compliant with EC 1935/2004 is also available for food-contact applications.
L series
L series plunger pumps are designed for high-pressure and high-flow dosing applications. The series covers flow rates from 0.2 to 5,500 l/h, with a maximum operating pressure of 500 bar according to the manufacturer. The modular design allows several pump heads to be combined in one configuration. The L series can also be used with liquids at temperatures of up to 280 °C.
The series meets the requirements of API 675, and ATEX-compliant models are available.
