Yuken PV2R Vane Pumps
These pumps have been developed especially for low noise operation. To comply with a wide range of applications for instance the injection molding machine. PV2R Series Single Pumps provide a wide range of delivery volume [5.8-237.0 cm3 /rev.] for the pumps. The main internal spare parts of the pumps are built in as cartridge kit. Therefore, the replacement can be easily done by simply changing the cartridges.
- If PV2R3 - 116 is used at speed above 1700 r/min. the suction pressure is limited to 0 Kgf/cm2
- If PV2R4 - 237 is used at speed above 1700 r/min. the suction pressure is limited to 0.13 Kgf/cm2
- If phosphate ester or water containing fluids are used, the maximum speed is limited to 1200 r/min.
- For starting at low speed, the maximum viscosity is limited.
- For pressure above 160 Kgf/cm2 raise the speed over 1450 r/min.
- For the brands of ‘Antiwear type water glycol’ and ‘Specially specified’ petroleum based oils see the ‘Hydraulic Fluids” in EIC-N-1001.
