"PV2R" Series Double Pumps
These double pumps consist of two PV2R seires single pumps combined in tandem within a single housing and driven by a common shaft.
A single suction port and two discharge ports are provided so that the output flow can be supplied to separate circuits.

designation shown on the right side.
2. In case of using socket welding flanges, there is a case where the operatingpressure 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.
3. When phosphate esters are used, prefix "F-" to the model number.
