I. Product Overview:
The 3G triple screw pump is designed and manufactured in accordance with the national standard GB10887-89. A triple screw pump is a type of positive displacement rotor pump, primarily utilizing the principle of screw meshing. It relies on the rotating screws intermeshing within the pump casing to encapsulate the medium being conveyed within the meshing chamber, continuously and uniformly pushing it along the screw shaft to the discharge outlet, thereby providing the system with stable pressure.
The 3G three-screw pump is suitable for conveying various non-corrosive oils and similar oils as well as lubricating liquids. The viscosity range of the conveyed fluids is generally 3.0~760 mm²/S (1.2~100°E), and high-viscosity media can be transported after being heated to reduce viscosity. The temperature does not usually exceed 350°C.
Section II: Product Features:
Wide range of pressure and flow rates, flow range 0.2~600 m3/h, with a maximum working pressure of up to 6.3 MPa.
(2) Wide range of liquid types and viscosity.
(3) Due to the lower inertia force of the rotating components within the triple-screw pump, it can operate at a high rotational speed.
(4) Excellent inhalation performance with self-priming capability;
(5) Even and continuous flow, low vibration, and low noise.
(6) Less sensitive to incoming gases and debris compared to other centrifugal pumps.
(7) The three-screw pump has a sturdy structure and is easy to install and maintain.
(8) Strong self-priming capability.
(9) The general-purpose component series offers various structures, suitable for horizontal, flanged, and vertical installations.
(10) Heating or cooling structures can be provided as required by the medium being transported.
Section 3: Application Scope:
The 3G triple screw pump can be used as a then pump and transfer pump in heating equipment. In oil transportation systems, it serves as a transfer and fueling pump. In the mechanical industry, it can be used as a hydraulic pump, lubrication pump, and remote control motor pump. In the chemical, petrochemical, and food industries, it can be used as a supply pump. On ships, it is used as a transfer pump, booster pump, fuel injection pump, lubrication pump, and ship pump.
The 3G triple screw pump is widely used in various industries such as oil, power, chemical fiber, shipping, metallurgy, glass, machinery, machine tools, and highways. It is suitable for transporting fuel oil, hydraulic oil, lubricating oil, asphalt, and other similar lubricating liquids.
