PRODUCT OVERVIEW
Designed around the operating conditions.
Shanghai Shangcheng Pump & Valve Manufacturing Co., Ltd. supplies G Series progressive cavity pumps for viscous liquids, sludge and process-media transfer, with model selection based on the actual fluid and operating duty.
Confirm the medium, viscosity, solids and particle condition, required flow, discharge pressure or total head, temperature, suction condition, operating speed, stator compatibility and installation / motor requirements.
G series progressive cavity pumps move liquid through sealed cavities formed by the rotor and stator. Their steady, low-pulsation delivery makes them suitable for viscous and consistency-sensitive media when rotor, stator and speed are correctly matched.
For viscosity, solids and operating-speed review, read our screw pump selection guide.Screw pump selection guide
AVAILABLE PRODUCT TYPES

Hopper-Fed Progressive Cavity Pump
Hopper inlet configuration for reviewed viscous and poor-flowing media. Review hopper-assisted feeding where the medium cannot reliably enter a standard inlet.
View model details ↗TYPICAL APPLICATIONS
- Sludge transfer
- Food and beverage processes
- Oil and emulsion handling
- Chemical and polymer transfer
SERIES ADVANTAGES
- Low-pulsation flow
- Suitable for viscous media
- Flow can be adjusted through speed selection where the configuration allows.
- Multiple drive and speed options
INFORMATION FOR SELECTION
- 01Viscosity and solids
- 02Required flow and pressure
- 03Temperature
- 04Chemical compatibility with stator
APPLICATION FIT
Where this series fits—and what to confirm first.
Steady transfer of viscous, shear-sensitive or consistency-changing liquids and sludge.
For clean water and higher pressure in a small footprint, review a CDLF multistage pump.
- Do not run the pump dry unless a special arrangement is supplied.
- Speed should be reduced as viscosity or abrasiveness increases.
- Stator material and liquid compatibility are decisive for service life.
