G Series Marine Single Screw Pump

Product Name: G Series Marine Single Screw Pump

Product Overview:The G Series Marine Single Screw Pump is a heavy-duty positive displacement pump specifically engineered to meet the rigorous demands of the marine and offshore industries. Built with robust materials and a highly adaptable design, this pump excels at handling the most challenging fluids found on vessels, including high-viscosity fuels, sludge, and oily water mixtures. Its exceptional self-priming capability and smooth, non-pulsating operation make it an indispensable piece of equipment for ship engine rooms, ensuring reliable fluid transfer in even the harshest maritime environments.

Key Features & Structural Advantages:

• Exceptional Media Versatility: This pump is designed to handle a wide spectrum of marine fluids with ease. It efficiently transfers highly viscous media (such as heavy fuel oil and sludge) and liquids containing solid particles, short fibers, or abrasive impurities without clogging or causing structural damage to the medium.

• Powerful Self-Priming Performance: A critical feature for marine applications, the G Series boasts an impressive self-priming lift of up to 6 to 8.5 meters. This allows the pump to quickly draw in fluids from bilges or deep tanks, ensuring rapid and reliable startup without the need for complex pre-filling systems.

• Smooth & Low-Shear Operation: Utilizing the progressing cavity principle, the pump creates sealed chambers that move axially to push the fluid forward. This results in a continuous, steady flow with absolutely no pulsation, vibration, or turbulence. Its low-shear action is perfect for sensitive media like oily water emulsions, ensuring the fluid's original structure remains intact.

• Robust Marine-Grade Construction: Built to withstand the demanding conditions of life at sea, the pump features a compact and durable structure. The core components, including a rigid rotor and an elastic stator, are crafted from high-quality materials (such as stainless steel and wear-resistant rubber) to ensure excellent corrosion resistance and a prolonged service life.

• Easy Maintenance & Flexible Drive: The G Series has a simple design with minimal parts, making on-board maintenance and repairs straightforward. It offers flexible installation options and can be directly coupled to an electric motor or driven via a gearbox, allowing for easy integration into existing shipboard systems.

Technical Specifications:

• Flow Rate: Highly customizable based on specific model and speed (typically ranging from 0.8 to 150 m³/h)

• Pressure Rating: Single-stage up to 0.6 MPa; Multi-stage configurations available up to 2.4 MPa or higher

• Viscosity Range: Capable of handling viscosities up to 1,000,000 cP (centipoise)

• Solid Handling: Excellent at passing solid particles and fibrous materials commonly found in bilge water and sludge

• Temperature Limit: Standard models up to 120℃; high-temperature variants available up to 150℃

• Material Options: Rotor (Stainless Steel 304, 316, 316L); Stator (Various high-quality rubber compounds like NBR, EPDM to suit different marine fluid compatibilities)

Typical Marine Applications:

• Bilge & Ballast Systems: Highly effective as a bilge pump for removing oily water, sludge, and wastewater from the bottom of the ship's hull.

• Fuel Oil Transfer: Ideal for the reliable transfer, boosting, and circulation of heavy fuel oil, diesel, and crude oil in marine fuel supply systems.

• Sludge & Waste Handling: Perfect for pumping thick sludge, oil residues, and sewage to shore reception facilities or onboard treatment plants.

• Deck & Hull Cleaning: Used for supplying seawater or cleaning agents for deck washing, hull cleaning, and fire-fighting support systems.

• Lube Oil Transfer: Serves as a dependable pump for transferring various grades of lubricating oils across the vessel.
