● This pump is designed for transporting media with a temperature of up to 150 ℃, viscosity ranging from 3 to 760 cSt, free of solid particles, non-corrosive, and possessing lubricity. It operates within a pressure range of 0.6 to 2.5 MPa and a flow rate of 0.6 to 123 m³/h. It is widely used in industries such as fuel delivery, hydraulic systems, marine engineering, and petrochemicals.

● Key applications include: 1. Continuous and linear fluid transmission without stirring or pulsation; 2. Low vibration and minimal noise during operation; 3. High-pressure capability and high efficiency; 4. Simple structure that allows for easy disassembly and maintenance; 5. Compact size and lightweight design; 6. Minimal wear and extended service life.

● The pump typically features a mechanical seal and is driven by a motor through a claw coupling. The shaft rotates clockwise, ensuring smooth and stable operation.

● The main materials used are: - For the screw: 16MnCrS5, 40Cr, 45, 38CrMoALA - For the pump body: HT200, QT450-10, ZCuSn10Pb, ZG270-500

● The 3G-type universal screw pump is divided into five different series based on its application, each with specific performance ranges: - 3G Series: Suitable for transporting lubricants with a viscosity of 3–20oE, temperature ≤ 80 ℃, operating pressure 0.6–570 MPa, and flow rate 2.5 m³/h. - 3GR Series: Designed for heavy fuel oil with a viscosity of 3–50oE, temperature ≤ 120 ℃, pressure range 0.6–570 MPa, and flow rate 2.5 m³/h. - 3GL Series: Ideal for light fuel oil with a viscosity of 1.2–5oE, temperature ≤ 120 ℃, pressure 0.6–570 MPa, and flow rate 1.6 m³/h. - 3GW Series: Used for high-temperature heating oil with a viscosity of 3–50oE, temperature ≤ 150 ℃, pressure 0.6–363 MPa, and flow rate 1.6 m³/h. - 3GN Series: Designed for high-viscosity oil with a viscosity of 100oE, temperature ≤ 80 ℃, pressure 0.6–636 MPa, and flow rate 2.5 m³/h.

This pump is an ideal solution for various industrial applications due to its reliability, efficiency, and versatility. Whether you're dealing with lubricants, fuels, or viscous oils, the 3G-type screw pump provides a durable and efficient pumping solution. Its advanced design ensures long-term performance and minimal maintenance, making it a popular choice in demanding environments.
