1 P SRS P PUP P Series P Pump 3.6 to 1.9cm 3 /rev 3Pa This is a new design series in which all pump types are installation compatible with previous designs. ote, however, that there is no longer compatibility for some of the seal components between the P-3 and P-4 sizes and design numbers 1 and 12. eatures q A patented axial and radial pressure loading system provides high efficiency and generates pressures up to 3Pa {36kgf/cm 2 }. Specifications w utstanding durability and very long life. e A modified involute short-tooth gear enables internal gearing for greatly reduced pulsation and noise, and exceptionally quiet operation. r A simple structure makes maintenance and inspection easier. apacity cm 3 /rev Rated Voltage Pa aximum perating Pressure Pa{kgf/cm 2 } inimum Revolution Speed min 1 aximum Revolution Speed min 1 Type A Weight kg P-2A() {} 3 {36} P-3A() {} 3 {36} P-4A() {} 3 {36} P-A()- 4-21(11) {} 3 {36} P-6A()- 8-21(11) {} 3 {36} ote) 1. apacity: ogical discharge rate per rotation. 2.

P 4 2 T 2 andling z or the hydraulic operating fluid, use an R& type and wear-resistant type of S V32 to 68 or equivalent (viscosity index of at least 9). Use hydraulic operating fluid that provides kinematic viscosity during operation in the range of 2 to 1mm 2 /s. x The operating temperature range is to 6. When the oil temperature at startup is or less, perform a warmup operation at low pressure until the oil temperature reaches.

Provide a suction strainer with a filtering grade of about 1μm (1 mesh). or the return line to the tank, use a μm line filter. n anage hydraulic operating fluid so contamination is maintained at class AS1 or lower. Take care to avoid contamination with water and other foreign matter, and watch out for discoloration. Whitish fluid indicates that air has contaminated the fluid, and brownish fluid indicates the fluid is dirty. m perate within the RP range in the catalog for the minimum RP of the pump. Unload the pump's load pressure to operate at variable speeds. ondition of inflow piping must produces as little inflow load pressure as possible to minimize effect of cavitation.

2 , When using water- or glycol-based hydraulic operating fluid, refer to page -3 for details on applicable models of hydraulic pumps.. At startup, repeat the inching operation (start-stop) to bleed air from the pump and pipes. quip an air bleed valve in circuits where it is difficult to bleed air before startup.
