Design No. 30 is applied on PVS-0B to make the pump more compact and lighter, and reduce noise.
Production of PVS-3B has been discontinued. Use PZS-3B.
Pressure adjustment 3 type has been added to PVS-1B-22 and PVS-2B-45. (Design No. 20 is applied only on PVS-2B-45*3.)
Proprietary low-noise mechanisms are incorporated on the shoe, swash plate, valve plate, and other locations to en-sure silent operation. In particular, a semi-circular barrel swash plate stabi-lizes operation characteristics to ensure silent operation.
Set the length of insertion between coupling and hydraulic pump shafts so that it is within at least 2/3 or more of the coupling width.
