Gerotor, Gear and Cam Pumps

The gerotor, gear and cam pumps in this brochure are lubricant pumps that can be used for a large number of tasks.

The drives of gear and gerotor pumps must not be subjected to radial or axial loads.

The indicated delivery rates apply to an operating viscosity of 140 mm2/s and a back pressure of 5 bars. If the operating viscosities or back pressures deviate from these values, the delivery rate and power requirements will change.

Permissible operating viscosity: 20 to 1000 mm2/s.

FilteringThe pumps require filtration of the lubricant for a maximum particle size of 100 µm.

If the metering elements, valves, flow moni-tors, etc. as well as the friction points to be supplied require finer filtration, that must be provided for in the delivery line (recom-mended value 25 µm).

Gerotor pumpsfor clockwise or counterclockwise rotation, but with constant direction of rotation and delivery

Gerotor pumps are distinguished by quiet running and little pulsation. They have an internally geared delivery elemen t (trochoid gearing).

Gerotor pump for clockwise and counterclockwise rotation,but for constant direction of delivery with changing direction of drive shaft rotation to DIN 69001, Part 17 A

This pump is especially suitable for direct gear drive.

When the pump is used in systems that do not have an open delivery line, e.g. which have a check valve, safety valve or closed bearings, it is necessary to provide for a venting aid.

Cam pumps for clockwise or counterclockwise rotation,but for constant direction of delivery with changching direction of rotation

With these valveless piston pumps the piston is driven directly via a cam so that only three constantly moving elements are involved.

This configuration results in dependable operation and a long service life.

The fluids to be pumped must have enough lubricity for the pump to lubricate itself.
