Cam pump 206-100 for use in SKF CircOil centralized lubrication systems

These cam pumps are lubricant pumps that can be used for a large number of tasks. 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.

Filtering

The pumps require filtration of the lubricant for a maximum particle size of 100 μm. If the metering elements, valves, flow monitors, etc. as well as the friction points to be supplied require finer filtration, that must be provided for in the delivery line (recommended value 25 μm).

Cam Pumps

For clock- or counterclockwise rotation, but for constant direction of delivery with changing 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.
