I. Product Overview:

The 3G tri-screw pump is designed and manufactured according to the national standard GB10887-89. A tri-screw pump is a type of rotary vane positive displacement pump, primarily utilizing the principle of screw meshing. It relies on the rotating screws meshing within the pump housing to enclose the medium being conveyed in the meshing chamber and continuously and uniformly propel it along the screw's axial direction to the discharge outlet, providing a stable pressure for the system.

The 3G triple screw pump is suitable for conveying various non-corrosive oils and similar oils, as well as lubricating liquids. The viscosity range of the fluid conveyed is generally 3.0～760 mm2/S (1.2～100°E), and high-viscosity media can be transported after heating to reduce viscosity. The temperature is usually not more than 350°C.

II. Product Features:

Wide range of pressure and flow rates, with flow rates from 0.2 to 600 m3/h and a maximum working pressure of up to 6.3 MPa.

(2) Wide range of liquid types and viscosity options available.

(3) Due to the lower inertial force of the rotating components within the triple screw pump, it can operate at a high speed.

(4) Excellent inhalation performance with self-suction capability.

(5) Uniform and continuous flow; low vibration and noise.

(6) Less sensitive to incoming gases and debris compared to other centrifugal pumps.

(7) The triple screw pump features a sturdy structure and is easy to install and maintain.

(8) Strong self-priming ability.

(9) The general combination series of components features various structures, suitable for horizontal, flanged, and vertical installations.

(10) Additional heating or cooling structures can be provided as required for the medium being conveyed.

III. Application Scope:

The 3G tri-screw pump can be used as both a feeding pump and a conveying pump in heating equipment. It serves as a conveying and fuel-injection pump in oil transportation systems, and can be employed as a hydraulic pump, lubrication pump, and remote-controlled motor pump in the mechanical industry. In the chemical, petrochemical, and food industries, it can be used as a supply pump. On ships, it is used as a conveying pump, pressure boost pump, fuel injection pump, lubrication pump, and marine pump.

3G triple-screw pumps are widely used in various industries such as petrochemical, electric power, chemical fiber, shipbuilding, metallurgy, glass, machinery, machine tools, and highways. They are suitable for transporting fuel oil, hydraulic oil, lubricating oil, asphalt, and other similar lubricating liquids.
