RA20/45 Electric Drive Pumps (Copy)

For multi-line lubrication systems

The RA 20/45 radial piston pump features a modular design that allows for the use of up to three composite pump elements, as well as the ability to reduce or increase the number of outputs. The output of all pump element outputs is adjustable via a single control unit, ranging from 33 to 100 %. The grease reservoir is equipped with a mixing device and a screw conveyor for pressurized grease delivery into the suction chamber. This feature, combined with a wide range of gear ratios, ensures a low, continuous flow of lubricant without the need for additional on/off timers.

Technical characteristics and advantages
