What is an impeller?

An impeller is commonly used in underground well water systems to provide potable water.

An impeller is a blade operating inside a piece of pipe that causes water to be propelled through it at high speed. The impeller acts like a jet engine and forces fluid through a tube at high pressure. In manufacturing, impeller pumps are used to push fluids to and from workstations and machines at great pressure and speed. The impeller pump pushes water off the rotating blade and against the pipe wall to create pressure.

An impeller has blades that drive water.

Many objects in common use today use an impeller pump. Personal watercraft such as jet skis use an impeller to push water out of the back of the machine. The turbocharger in automobiles and trucks uses an impeller to compress the incoming air and force it into the induction system. Many underground well water systems use one to pump potable water up and out of the well and into the house.

Jet skis employ impellers to force water out the back.

By utilizing the high pressure characteristics of an impeller pump, a smaller pump motor and pipeline can be used to transport a large amount of water or fluid. By pushing fluid through a pipe line at high pressure, high velocity fluid displacement can be achieved.

This process also allows a manufacturing site to maintain high pressures and volumes across a large number of outlets. A manufacturing facility needs to compensate for the pressure loss that occurs when multiple outlets are drawing fluid from the system at the same time. Many machines are designed to operate at a predetermined pressure to function properly. Using the proper system, several or all job sites can be operated simultaneously without a drop in supply line fluid pressure.

These pumping systems are typically quiet and trouble-free and require little maintenance. The drive unit is easily removed from the pump unit in the event of replacement, allowing for limited interruption maintenance. Many advances in composite design are enabling pump components that can operate in extreme conditions for extended periods of time without failure. In addition, sealed bearings allow extended operation without the need for greasing or lubrication.

Modern manufacturing lubrication and fluid drive requirements have led to advantages in many facets of life. Pumping stations around the world are benefiting from the design of higher flow pump styles. Consumers are using this technology to relax and play, in many cases, without a second thought.
