Selecting a gear pump for heavy oil, asphalt, or bitumen is not just a matter of naming the liquid and asking for a flow rate. These media can be highly viscous, strongly temperature-dependent, and difficult to move during startup if the system is not heated or if the suction side is restrictive.

Choosing the right high viscosity gear pump is not only a matter of matching flow rate and pressure. Viscous fluids behave differently from water-like liquids: they may resist suction, require heating, create high starting torque, or become difficult to seal when temperature rises. For buyers and engineers, a good pump selection should start with the actual working conditions of the fluid and the process.

Gear oil pumps are rotary pumps that transport or pressurize liquids through the variation and movement of the working volume formed between the pump casing and meshing gears. The quality of the installation directly affects the pump’s performance and service life. This article provides a comprehensive guide on how to install a gear oil pump and important precautions to ensure optimal operation and longevity.
