Pumps H40
eccentric piston, are intended for forcing of pure mineral oil in hydraulic systems of machines, press, elevators and other cars where the unregulated productivity and a high pressure is required. These pumps work at the pure mineral oils "Turbine 22" and "22-P" of GOST 32-74, "VNIINP-412" and other oils having similar qualities at a temperature from 0 to 50 °C. The technical characteristic of the pump is given during the work on pure mineral oil "Industrial 20" at a temperature of 50 °C. Technical characteristics of the radial and piston pumps H40
