G Series Ship Single Screw Pump | Versatile & Efficient Fluid Transfer Solutions

Product Overview
The G Series Ship Single Screw Pump is an internally-meshing, hermetic rotary pump specifically engineered for challenging marine applications. Renowned for its exceptional media adaptability, smooth pulsation-free flow, and superior self-priming capabilities, this progressive cavity pump outperforms conventional pumping technologies. Its unique working mechanism involves an eccentric rotor and resilient stator that create sequential sealed chambers, ensuring consistent volumetric displacement without turbulence or agitation. Crafted with specialized elastomeric materials, the G Series effortlessly handles high-viscosity fluids, abrasive slurries, and fibrous media where other pumps fail.
