Product Description

Application:
This series three screw pump applies to deliver clean and non-corrosive medium which has lubricating property at

temperature below 150 centigrade with the viscosity of 3-760cst, The pump's working pressure range form 0.4Mpa to

6.0Mpa and flow capacity range from 0.4m3/h to 200m3/h.

Feature
(1)Medium is delivered in axial direction continuously without agitation and pulsation.
(2)Small vibration and low noise
(3)High pressure and high efficiency
(4)Simple structure, easy disassembly and assembly
(5)Small volume and lighe weight
(6)Slight wear and long life of the pump

Structure:
The pumps are sealed generally by mechanical seal and driven by the motor through the claw coupling.

Material:
The driving and driven screw 16MnCrS5, 40Cr, 45, 38CrMoALA
Pump casing: HT200, QT450-10, ZCuSn10Pl, ZG270-500
