Self-controlling vane pumps type PSV
Special features: Long service life due to hydrodynamic, spherically located friction bearings
Low tolerance between adjustment and spacer ring = minimal oil leakage
Almost constant oil leakage over the compete pressure range due to hydraulic play compensation
 
Technical specifications:
Installation position: Unrestricted. The pump drive shaft must not be subjected to radial loads.
Operating temperature: To prevent corrosion, the oil temperature in the tank should not exceed 55°C.
Suction: 152 mm HG
76 mm with aqueous fluids
Operating pressure: Max. 140 bar
Pressure limits: A pressure control valve should b e used with pressures in excess of 100 bar, as this would guarantee higher service life of the pump with high pressure peaks.
Direction of rotation: The SV pumps are available with clockwise and counter-clockwise rotation. The respective direction of rotation is marked by arrows located on the side of the pump housing. The direction of rotation is seen from the end of the shaft.
Pressure fluids: HLP - Mineral oil i.a.w. DIN 51525
Filtering: to ensure long service life of the pump, a return line filter with a mesh of at least 1 my is recommended. Suction filters should not be used.
