Electric pump motors
An electric pump doesn’t achieve much without a properly working motor. Did you know that the motor as we know it was patented by a Serbian called Nikola Tesla on 1 May 1888? The picture above shows some of his drawings, of a 6-pole motor, that accompanied the patent application, and the motors of today are essentially built according to this pattern (and yes, the Tesla motor car was named after him too).
The seals and bearings are important on motor-driven pumps, but the other important part is the insulation on the motor windings. Over time this will usually eventually fail, and can be rewound if it’s economically sensible to do that.
We check the motor when we carry out a pump service. If a pump motor has gone down we’ll respond quickly to get the pump up and running again as soon as possible.
