G Series Single Screw Slurry Pump



>>>Pump Description

The G series single screw pumps are designed based on positive displacement technology. The core components include a single screw (rotor) and a fixed bushing (stator). Due to the unique geometry of the rotor and stator, two independent sealing chambers are formed. This ensures stable pressure and smooth flow, even at low speeds. These pumps are ideal for handling a wide range of fluids, including those with temperatures between 80°C and 150°C.

These pumps can be driven directly by a coupling or via an adjustable speed motor, belt drive, gear box, or other accessories. Their versatility makes them suitable for various industrial applications.

>>>Pump Features
1. Wide range of applications – suitable for all types of flowing media and non-runny liquids.
2. Steady flow and pressure with no pulsation.
3. Adjustable speed allows for precise control of flow rate, making it ideal for metering systems.
4. Strong suction power, low noise, no leakage, and minimal temperature rise.

>>>Pump Application
A. Petro Industry: Thick oil delivery, oil-gas mixture transport, waste oil recovery, sewage treatment, polymer delivery.

B. Chemical & Pharmaceutical: Pastes, emulsions, suspensions, liquids containing gas and solids, non-mixable or sensitive media.

C. Environmental Engineering: Sewage, sludge dewatering, flocculant measurement, oil-water separation, desulfurization.

D. Mining & Minerals: Water gas equipment, titanium white production, kaolin and calcium carbonate processing, feed systems, electrolyte treatment.

E. Food Industry: Dairy products, juices, purees, condiments, beer, and brewing.

F. Paper Industry: Raw material handling, coating, tinting, chemical dosing, sludge and wastewater treatment.

>>>Transportation Medium:
Liquids with varying viscosities, especially thick materials that are hard to pump.
Liquids with different concentrations and dry particles after dehydration.
Liquids containing solid particles, fibers, or suspended matter.
Mixtures of liquid, gas, and solid.
Sensitive liquids that cannot be mixed, cut, or damaged.
Corrosive liquids.
