Products / GEAR-PUMPS / Design Version «N»
Gear Pumps of this type are developed for dimension-type groups 2, 2.5 and 3. The pump housings are manufactured of high-strength aluminum extruded profiles and equipped by PTFE-bearings. These pumps are developed for dimension-type 20…50 ccm/rev of the fifth version for hydraulic systems with the pressure up to 270 kg/c/cm². Gear Pump GP25-4 is developed with port dimensions, which refer to the gear pump PZ2-25KS produced by Hydrotor plant,
