  • Maintain Pump’s Operation with Impeller Balancing

Successful pump performance needs to be cared for with regular maintenance to continue a healthy lifespan. Just like a car, the pump needs a tune up every so often. Pumping devices are the backbone of many commercial industries. They are active in neutralization of biofuel processing and water treatment industries constantly process chlorine and sodium hypochlorite and pumping these chemicals out to provide clean water is a must. To maintain power and proper use, impeller balancing can ensure the pump’s flow of passage at a high rate.

Impeller balancing is fundamental for prime function and pump preservation. With advanced technology equipment, Pumpman Inc. has the ability to service and repair all industrial and commercial pump systems. For affordability and quick service, Pumpman provides technical services including precision pump shaft laser alignment, pump repair and dynamic impeller trim and balance.

Balancing involves adjusting the impeller that zeros out unbalance and eccentricity. To balance a single plane imbalance, weight needs to be evenly distributed. In a two plane unbalance, sometimes called couple unbalance, it is corrected by adding two correction weights equidistant from each other.

For both single plane and two plane unbalance, this is called dynamic unbalance and corrected by repairing both eccentricity from the static unbalance and the wobbly movement.

The balancing instrument customizes the level of automation with an easy to use touch screen to guide the precision tool for short and long impellers.

Why do industries need impeller balancing?

Balancing is the process of minimizing vibration, noise and bearing wear of rotating bodies. Pumps and impellers require proper balancing to prevent cavitation. The impeller in a centrifugal pump must rotate in the correct direction. To determine the pump’s direction, pumps with a single electrical source do not have a problem achieving proper direction, but a three phase electrical source must have the proper sequences of the three wires that supply power. Balancing will always be one of the most cost effective means of providing quality products to consumers.

According to the International Standards Organization, their guidelines regarding pump impellers suggest a balance grade of G-6.3. Meaning that the grade is balanced on a rotor to run at 3600 rpms. The ISO standards are specific methods of configuring static and couple unbalance tolerances, dependent on ratio of the part’s diameter to length.

What is the importance of trimming?

Impeller trimming refers to reducing the diameter of an impeller. As the impeller diameter is reduced, clearance between the impeller and the fixed pump casing increases recirculation. It is often an alternative to replacing the entire pump assembly, which allows for longer lasting lifespan.

Oversized throttle pumps produce excess pressure, which makes it a perfect candidate for replacement or trimming, this helps reduce costs and saves energy. In addition, impeller trimming reduces wear and tear on system piping, valves and other components.

What happens if the pump is not serviced for impeller balancing?

Balancing can prevent vibration and increase efficiency. Without providing balance to pumps noise will not be reduced, higher operating speeds will not be achievable and bearing life will not last compared to other pumps. By being slightly off, the level of efficiency reduces the pump input power, putting an end to energy wastage. This can also lead to accidents to servicemen and employees.

For well-trained, qualified service you can trust Pumpman Inc. to keep your pumps in factory condition. Impeller balancing ensures that the speed and efficiency meets company standards, while protecting against cavitation.
