G Single screw pump

Robust single‑screw positive‑displacement pump engineered for reliable transfer of viscous, corrosive and solid‑laden liquids. Designed for continuous, low‑pulsation discharge with stable pressure and straightforward maintenance, this pump is suitable for food processing, metallurgy, construction, pharmaceutical and chemical applications.

Key features

• Construction: single‑screw rotor (eccentric helicoid) and double‑helix stator form a series of sealed cavities that convey fluid smoothly and continuously.
• Materials in contact with product: top‑grade acid‑resistant stainless steel for metal wetted parts; shaft made from 2Cr13 stainless steel; non‑toxic rubber stator bush with no peculiar odor.
• Performance: handles viscous media (up to 10,000 Pa·s as specified), slurries and suspensions containing solid grains or rubber particles; suitable for corrosive liquids and foodstuffs.
• Temperature rating: reliable operation up to 100 °C.
• Operation: electric motor drives the rotor which both rotates and rolls inside the stator; fluid advances one screw pitch per rotation, producing a steady, metered flow.

Commercial benefits for B2B purchasers

• Low pulsation, consistent flow rate — useful for dosing, filling and continuous transfer lines.
• Simple mechanical design reduces downtime and simplifies maintenance and spare‑parts stocking.
• Food‑compatible options (non‑toxic rubber stator) and acid‑resistant metal wetted parts expand applicability across sanitary and aggressive environments.
• Capable of handling solids and high viscosity fluids that would challenge centrifugal pumps.

Typical applications

• Food industry: transfer of food slurries, pulps and viscous sauces.
• Chemical and pharmaceutical plants: transfer of corrosive solutions and viscous formulations.
• Metallurgy and construction: handling slurries, adhesives, sealants and similar materials.

Notes for specification and procurement

• Confirm required flow rate, discharge pressure and maximum particle size when specifying pump size and rotor/stator combination.
• Verify compatibility of stator rubber compound with your product (temperature, chemical resistance) for long service life.
• Provide motor specification (power, speed) and desired connection/flange options when requesting quotations.

This pump is offered as a rugged, easy‑to‑service solution where consistent metering and the ability to convey viscous or solid‑bearing fluids are required.
