Flowserve GR Series Double Helical Rotary Gear Pump

The Flowserve GR Series Double Helical Rotary Gear Pump is a heavy duty positive displacement rotary gear pump designed for smooth handling of viscous liquids in industrial process applications. Built with a between bearing design and double helical herringbone gears, the GR Series supports stable, pulse free flow for oil circulation, petrochemical transfer, filtration systems, asphalt, grease and other viscous fluid applications.

This pump is suitable for users who require reliable viscous liquid transfer, circulation and process pumping performance. For technical selection or quotation, contact us with your required flow rate, pressure, temperature, viscosity and application details.

Key Features and Benefits

Double helical herringbone gear design: Supports smooth and pulse free flow for viscous liquid handling.
Between bearing construction: Helps reduce shaft deflection and supports stable pump operation.
Positive displacement operation: Provides consistent flow for transfer and circulation duties.
Self priming capability: Suitable for selected process transfer applications where priming support is required.
Low NPSHR design: Helps improve suction performance when correctly selected.
Packing or mechanical seal options: Allows configuration based on process and sealing requirements.
Back pullout design: Supports easier maintenance access without major piping disturbance.
