Brief Introduction
2W Twin Screw Pump
The twin screw pump is designed to handle a wide range of non-solid and high-viscosity fluid media. Known for its reliability and versatility, it can operate effectively whether the medium is lubricated or not, and whether it is corrosive or contains gas and liquid mixtures.

**Key Parameters:** 1. Capacity: 0.5 - 2000 m³/h 2. Pressure: 0.1 - 3.0 MPa 3. Viscosity: 0 - 100,000 cSt 4. Temperature: -30°C to 250°C **Main Features:** 1. Smooth and pulsation-free delivery of various fluids, thanks to the sealed working elements and the casing design. The pump has excellent self-priming capability and can handle liquid mixtures containing gas or oil. 2. High suction performance with very low NPSHR, ensured by the unique pump design. 3. Equipped with externally lubricated bearings, allowing the pump to handle non-lubricating media. 4. Uses synchronized gears, eliminating metal-to-metal contact between rotating parts, ensuring safe operation even during short dry runs. 5. Available in multiple configurations such as horizontal, vertical, and with liners. It can manage clean liquids without solid particles, low or high viscosity media, and even some corrosive media when appropriate materials are selected. 6. The suction port is located on the side, and the discharge is at the top, making it compact and ideal for use in confined spaces like ships.
