A Double Helical Rotary Gear Pump is a positive displacement pump designed to transfer liquids using specially shaped helical gears. Its design helps provide smooth pumping performance and reduce axial thrust under suitable operating conditions.
These pumps can handle compatible industrial liquids such as lubricating oil, diesel, fuel oil, and other viscous fluids. The liquid's viscosity, temperature, chemical compatibility, and operating conditions should be checked before selecting a pump.
The double helical gear design helps balance axial forces, supporting smoother operation and potentially reducing bearing loads compared with suitable conventional gear designs. Actual performance depends on the pump's engineering and operating conditions.
Some configurations support reversible operation, but bidirectional capability depends on the pump design, bearing arrangement, seals, and drive system. Confirm this requirement with the manufacturer before installation.
Routine maintenance may include checking for leaks, monitoring noise and vibration, inspecting bearings and seals, verifying lubrication requirements, and ensuring that the suction line remains unobstructed. Follow the manufacturer's maintenance instructions.
