series gear pumps are mainly composed
of gears, axles pump body, pump, cap
safety valve and axle-end seals etc.
The heattreated gears have the advantage
of higher hardness and intensity,
and rotate with the axles inside the
replaceable bearing sleeves. All of
pump's parts can be lubricated by
delivered medium when working.
The pump is properly designed with
leakage and return chute, which lets
the gears bear the least torque force
and reduces load and wear on bearings
bear the least torque force and reduces
load and wear on bearings in order
to raise pump's efficiency.
It is also designed with safety valve
for protection against overload. The
full return flow pressure of the safety
valve is 1.5times higher than the
rated exhaust pressure of the pump.
It can be also adjusted within the
allowance of exhaust pressure range
according to circumstances . But please
note the safety valve can't be applied
as pressure-reducing valve for long
time .You may install pressure-reducing
valve separately on pipe-line if needed.
