PG330
DEFINITION OF PRESSURES
P3 = Peak pressure
P2 = Intermittent operating pressure (1/3 of working time)
P1 = Continuous operating pressure
max. 20 s
GENERAL
Superior performance and reliability in
heavy-duty hydraulic application.
Construction with large area, low-friction
bushings provide strength, high efficiency, and long life in severe operating environments.
The design includes an advanced thrust plate and seal configuration,which optimizes performance even
in high temperature and low viscosity conditions.
Double pump with common suction reduces mounting costs, allow for a small package size.
WORKING CONDITIONS
- Pump inlet pressure (absolute pressure)
0,7 to 2,5 bar
10 to 36 psi
- Minimum operating fluid viscosity 1
12 mm 2 / sec
- Max starting viscosity
800 mm 2 / sec
- Suggested fluid viscosity range
17 - 65 mm 2 / sec
- Fluid operating temperature range
- 15 to 85 °C
- Fluid operating temperature range with FPM seals(Viton)
- 20 to 110°C
- Hydraulic fluid
mineral oil
Important:
in case of assembling of pumps without shaft seals, you have to keep the value of
min. suction pressure ( 0.7 bar (abs)) in the vane between pump and coupling too.
Lower pressure can lead to suction of oil through the front flange (seat of the shaft without seal);
this can damage seriously the pump.
1 - With reduction 80% of working pressure and at minimun speed.
Suggestion:
to have the best behaviour and duty life of the pump/motor, use a cooling system in order to keep the uid temperature at
60°C and viscosity at 20 cSt.In addition to the recommended ltration index of page 3.
