These high pressure, high performance pumps have been developed to meet space-saving requirements. These pumps are
a very compact version of the PV2R4, a vane pump series that has proven to exhibit outstanding low noise characteristics.
Specifications：

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.)
