Trim & Balance

Precision Machining

Having properly sized and balanced impellers makes an impactful difference in the accuracy and efficiency of your pump. We have a lathe for trimming impellers, and a balancing machine to balance impellers and rotors.

Operational Benefits


Adjusting the impeller size can optimize the pump's efficiency by reducing the pump head and lowering the flow rate; therefore, allowing the system to become customizable to the needs of the application. When a pump operates close to its best efficiency point (BEP), it consumes less energy, reduces operating costs, and prolongs the lifespan of the pump. Trimming the impeller can influence the Net Positive Suction Head (NPSH) required for the pump to operate without cavitation. Trimming allows for control of the NPSH characteristics to ensure the pump doesn't suffer from cavitation.


Tighter balance tolerances significantly reduce vibration levels and prevent premature bearing and ring wear. Balancing your rotating equipment is a must to ensure correct operation of your machine at a high level of efficiency and to extend the longevity of your pump. To reach our high standard of quality control, we balance every impeller that comes through our door. Our Asaki precision balance machine, operating with our EasyBalance computer software, work together to ensure precise measurements and accurate data reports.
