MODEL / G VARIABLE SPEED G Variable-Speed Screw Pump

PRODUCT OVERVIEW

Match the pump configuration to the actual medium.

This G-series configuration combines progressive-cavity pumping with adjustable drive speed. It is intended for applications where the delivery rate must be tuned to changing process conditions, while maintaining steady, low-pulsation transfer.

PRODUCT VIEWS

Six views of the G Variable-Speed Screw Pump.

TYPICAL APPLICATIONS

Sludge and wastewater transfer
Oil, emulsion and viscous-liquid handling
Chemical, polymer and additive transfer
Food and general process applications after compatibility review

INFORMATION REQUIRED

Liquid name, viscosity and operating temperature
Solids content, particle size and abrasiveness
Required minimum, normal and maximum capacity
Normal and maximum discharge pressure
Suction arrangement, pipework and installation conditions

OPERATING NOTES

Do not operate dry unless a special dry-running arrangement is supplied.
Reduce speed as viscosity, solids content or abrasiveness increases.
Confirm stator elastomer and all wetted materials against the exact liquid.
Provide safe pressure protection where the discharge can be blocked.

KEY DESIGN POINTS

Built around the medium, duty and installation.

Steady delivery

Progressive-cavity geometry supports low-pulsation transfer when the pump is correctly selected.

Viscous-media capability

Speed and pump size can be matched to viscosity and consistency after the liquid data is reviewed.

Material selection

Rotor, stator and sealing materials are selected together for chemical and temperature compatibility.

Drive options

Motor and speed-control arrangements can be coordinated with the required capacity range and site supply.

BEFORE ORDERING
