Fluid viscosity, operating temperature, pressure requirements and speed of rotation can influence the performance of any rotary gear pump head.
To optimise its performance, maintain proper fluid viscosity within the recommended range. Also, monitor and control operating temperature & pressure regularly.
Common issues include leaks around seals, excessive wear on gears & bearings, or cavitation due to improper fluid conditions or operating parameters.
