Zhejiang RenXiang Pump Industry Co., Ltd. stands as a premier specialized progressive cavity pump manufacturer in China, delivering heavy-duty fluid transfer machinery for global municipal, environmental, chemical, and food processing industries. Operating from advanced production facilities, RenXiang integrates precision engineering, custom design capabilities, and rigorous quality verification to produce feeding type single screw pumps capable of conveying extremely thick media with low fluidity.

Equipped with large feed hoppers, force-feeding augers, and durable rotor-stator assemblies, RenXiang's feed pumps ensure smooth, pulse-free material transport under continuous duty cycles. As a direct factory supplier offering standard and tailored OEM/ODM configurations, the company serves wholesale buyers, engineering contractors, and equipment distributors looking for high-torque performance, wear resistance, and reliable structural durability.

 

SEEPEX is a recognized technology developer specializing in progressive cavity pumps, open-hopper feed systems, and digital control integration. Their feed pump models feature custom ribbon augers and rectangular feed hoppers designed to crush and continuously transfer dewatered sludge, high-viscosity pastes, and bulk organic matter in wastewater treatment plants and biogas facilities globally.

NETZSCH manufactures versatile NEMO® hopper pumps with integrated feeding screw rods, serving heavy chemical processing, mining, and food manufacturing units. The company focuses on custom elastomer formulations, high-torque coupling shafts, and specialized feed chamber dimensions to ensure uniform fluid movement even when handling non-homogeneous, abrasive slurries with high solid concentrations.

PCM provides industrial transfer solutions engineered specifically for challenging fluid handling applications. Their hopper feed single screw pumps incorporate force-feeding screws and bridge-breaker mechanisms designed to manage sticky, cake-like products and fibrous materials without clogging, making them a frequent choice for OEMs and plant installations requiring continuous mass displacement.

Allweiler, part of the CIRCOR family, supplies heavy-duty progressive cavity pumps engineered with open feed hoppers and internal screw conveyors. Designed for severe industrial services, their feeding single screw pump lines support high-discharge pressures and precise volumetric metering across pulp and paper, marine, power generation, and chemical process engineering industries.
