3GR Series Double Jacket Three Screw Oil Pump
3GR Series Double Jacket Three Screw Oil Pump Application
3GR Series Double Jacket Three Screw Oil Pump applies to deliver clean and non-corrosive medium which has lubricating property at the temperature below 150°C, 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.
3GR Series Double Jacket Three Screw Oil Pump is widely used in the fields of machinery, petroleum & chemical industry, metallurgy, iron & steel, electric power, marine, Centralized lubrication unit, Lube circulation system, etc.
The pump is with double jacket casing which can be heated by hot steam, thermal oil, etc to reduce the viscosity of fluids with easy solidification. The pump can be made of special material, such as bronze, for liquid with low flashing-point like gasoline.
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 to disassemble and assembly
(5)Small volume and lighter weight
(6)Slight wear and long life of the pump
Structure: The pumps are sealed generally by a 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
