The KP…/434 high-pressure gear pumps are suitable for non-abrasive fluids. Examples of such fluids are, e.g., silicates (sodium silicate), isocyanates and polyols without fillers such as are used in PUR technology. The gear is supported in multicomponent plain bearings, is case hardened and is super-finished. The sliding plates are made of high-strength material with special surface hardness. Depending on the pumping medium, at drive speeds of 1500 1/min working pressures of up to 150 bar are feasible.
