● Applacation：
It applies to deliver clean and non-corrosive
medium which has lubricating property at temperature
below ≤150℃、with the viscosity of 5-760cSt,The
pump's working pressure range from 0.6MPa to
2.5MPa and flow capacity range from 0.6-123m3/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 light 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
Example of pump model
Eg：3G25×4-46
3G：three screw pump
25：out-side diameter of the driving screw 25mm
4：pitch number of the screw
46：46° pitch angle of the screw
R：heavy fuel oil
r：light fuel oil
W：high temperature heated oil
N：high visc oil
A：code of design improvement
S：double suction
● According to the application modes three screw
pump is divided into five series
