HAWE Radial Piston Pump Element MPE 4/5/6/7/8/9

The suction valve inlet of the pump element must be entirely below the oil level to prevent any air being drawn in.

The piston and roller bearings must be fully immersed under the oil level during continuous operation 

to ensure continuous lubrication.

Material: Steel; hardened, ground functional inner parts

Temperatures Ambient: approx. -40 - +80°C, Fluid: -25 - +80°C, Note the viscosity range!

Start temperature: down to -40°C is permissible (observe start viscosities!),

as long as the steady-state temperature is at least 20K higher during subsequent operation.

Biologically degradable pressure fluids: Observe manufacturer's specifications. 

By consideration of the compatibility with seal material not over +70°C.

efficiency : + 0.95

stroke frequency: min. 200 rpm, max. 2850 rpm

Below min. stroke frequency: volumetric efficiency will drop swiftly.

Above max. stroke frequency: suction problems may occur (with small cylinder diameters)

Weight:

MPE 4 - 9: 90 g

Drive type: motor via rotating shaft

Shaft rotation direction: any (direction of delivery remains unchanged)

A roller bearing is mounted eccentrically on the shaft. The outer race of the bearing acts on the back of the pump element.

This generates the lifting movement in conjunction with the return spring.

The flow rate is controlled by automatic suction and pressure control valves in the housing of the pump piston plunger.
