These pumps are of high pressure and high performance, which have been developed especially for low noise operation.To comply with a variety of applications including injection moulding machines, PV2R series single pumps provide the output flow of such a wide range as from 5.8 to 237 cm3/rev (.354 to 14.46 cu.in./rev).
The intergral driving parts of the pumps are combined into a kit form and available for supply as a cartridge kit.
Therefore, the replacement of the driving parts can be done easily.

Pipe Flange Kits
Pipe flange kits are available. When ordering, specify the kit number from the table below.
★1.In case of using socket welding flanges, there is a case where the operating pressure should be set lower than the normal because of strength of the flanges. Therefore, please pay cautious attention to the operating pressure when the socket welding flanges are used.
★2.As dimensions of the pipe flange mounting surface are conformed to SAE 4 Bolt Split Flange (Standard Pressure Series), pipe flanges conforming to the SAE Standards can be used.
Notes: Special seals (Viton seals) are required when phosphate ester type fluids are used. (Prefix “F-” to the pipe flange kit number when ordering.)
