●Size Calculation
|
●Operating
Pressure Range ____Outlet
Variable Pump
Port A Or B Rated Pressure ____40MPa
(Max.)Pressure Pmax____________45MPa
Auxiliary Pump
Rated Pressure Pb_____________2.5MPa
Peak Pressure Prmax__________4.0MPa
●Mounting Position
Optional:Pump housing must be filled with fluid.
●Flow Direction
Rotation,please refer to the below sheet of each control
detail for the relation between control and the direction
of flow.
●Filtration
Boost pump in suction line filtration (Equipped Auxiliary
Pump)
Would better use standard type filter.
Resistance to flow at the filter element：
V=30mm2/s, ｎ=ｎmax___ΔP≤0.01MPa
V=103mm2/s,ｎ=103r/min,ΔP≤0.03MPa
●Pressure for auxiliary
pump suction S
V=30mm2/s____________ΔP≥0.08MPa
When cold start______ΔP≥0.05MPa
Filter don't apply with side path valve,better with
resistance indicator filtration.

●Boost pump in pressure
line filtration (Equipped Auxiliary Pump)
Mounting Of Filter：
The rated size of the hole in the filter is 10um
regardless of the filter fitting separate in the pressureLine
or fitting direct in the variable pump.
Resistance to flow at the filter element：
V=30mm2/s ____________
ΔP≤0.1MPa
When cold start ________ΔPmax≤0.3MPa
(Valid ｎmin～ｎmax entire speed range)
It is better for filter to apply with side-path valve,if
so,please also apply with a resistance indicator.
When ordering,please note the details of the resistance
indicator clearly.If a fiter is required to fit in
the Variable pump.
Example：Voltage 12V or 24V
Direct or direct/ Voltage (12V or 24V)
