DESIGN

Twin-screw pump can transfer liquids that are not solid or
high viscosity like paste, used in many different fields.
• The twin screw pumps with a very wide range of applications
provide to transfer fluids containing gas, and various liquids as
reliable without the risk of corrosion or lubrication.
• The pump casing has enough medium without working,
because the inlet and outlet casing of the pump adopt special
design. This allows having a good self-priming performance of
the pump and water in the inlet line is discharged quickly.
• In case of high pressure, fluid is directed from the discharge
side to the suction side in order to reduce driving torque of the
pump thanks to the special design the by-pass valve on the
pump.

• Synchronous gear with individually lubrication transfer torque
form power screw to idler screw, for assuring without constant
and without kinetic deliver between transfer elements. So that
transfer element has high reliability when it transfers various
mediums, at the same time the pump doesn’t damage when it
works without oil in a short time.
• Specially designed hydraulic structure provides non-impact
fluid transfer by driving the shaft from suction side to the
discharge side.
• The pump casings of twin screw pump can choice different
constructions, so that it can transfer different medium under
different temperature.
