Brand: Worthington
Description:

The Flowserve Gearex is a double helical rotary gear pump with a timed non-contacting gear design, built for smooth flow transfer of viscous and clean fluids. Ideal for chemical processing, lube oil systems, and specialty industrial services, the Gearex pump delivers low pulsation output, high volumetric efficiency, and minimal wear.

The Flowserve Gearex double-helical, rotary gear pump is extremely rugged and unusually compact for its high capacity and range. Timing-gear-driven herringbone rotors are precision machined for vibrationless, pulseless discharge of viscous fluids.

Gearex Double Helical, Timed Rotary Gear Pump Applications

Chemical Processing, General Purpose, Greases and Fats, High Viscosity Polymers, Utility, Pulp and Paper, Petroleum Production and Refining, Syrups, Marine

  • Industries:
    OEM, Auxiliary, Chemical and Liquor, Food Processing, Miscellaneous Services, Pharmaceuticals

Double Helical Herringbone Gears provide quiet, pulse-free flow with better load carrying ability, greater strength and minimum hydraulic shock.

Timing Gears drive and transmit power, eliminating metallic contact of the pumping rotors and promoting long pump life.

Between Bearing Design virtually eliminates shaft deflection, even while accommodating heavy, highly viscous loads.

Heavy-Duty, Double Row Roller Bearings capable of carrying high radial loads, a short bearing span, and a husky shaft minimize rotor deflection.
