1 "PVR" SERIES Fixed Displacement- Single PVR/PVR Up to MPa ( ),. cm /rev (. CU.IN./rev) Pub. EC- These pumps are of completely unique design for extra high pressure applications. The excessive wear to the vanes and camring which usually occurs in shch high pressure vane pumps has been solved by means of adopting the special methods in both mechanical construction aspects and lubrication systems.

Use phosphate ester type fluids. When phosphate ester type fluid is used, prefix " F-" to the model number because the special seals (fluororubber) are required to be used. pumps can be used without conditions.

Control of contamination Contamination of hydraulic fluids results in pump failures and reduced pump lives. Carry out sufficient contamination control for hydraulic fluids and keep contamination level within NS class. lso, use a µm (-mesh) tank filter on the suction side, more than mm ( in.) away from the tank bottom. Instructions. lignment of shaft Employ a flexible coupling whenever possible, and avoid any stress from bending or thrust. Maximum permissible misalignment is less than. mm (. inches) TIR and maximum permissible misangular is less than.?. Suction pressures Set the suction pressure at pump inlet port at the value given in the table below. Furthermore, use the pipes in the suction side having the diameter as indicated on the installation drawings. In case where the pump is installed on the tank or at the position higher than the tank top cover, the height of the suction port of the pump should be less than metre (. ft.) from the oil level {less than. metre (. ft.) in case of using phosphate ester fluids or water containing fluids}.

Precautions at starting t an initial operation or at an operation after a long rest, the pump may have difficulty in sucking up fluid. In such cases, an air bleed valve should be installed beforehand on the discharge side (model No. ST- -, Catalogue No. Pub. EC-.), or discharge air by slightly slackening the connection on the discharge side. t starting, operate the pump intermittently as far as possible with no load. For fluid viscosity at starting, see the item of "Hydraulic Fluids".. Other precautions If a PVR series single pump is used at speed below r/min, install the pump with the suction port upside so that the pump can suck up fluid easily at starting. No.
