Common Failures

How to protect your pump from common failures

14 November 2013 by David Critchley


In our last blog we introduced you to the most common causes of pump failures - many of which can be prevented! In this latest blog we will guide you through some failure prevention methods so you can protect your pump through the winter months; the time of year when failures are more prone to occur.

Frost Damage

One of the most preventable failures is Frost Damage, this accounted for 8% of pump failures over the last year* (this is huge considering we’ve had one of the hottest summers of the century!). One of the first signs your pump has frozen is by looking at your pressure gauge; if the needle has over extended past its usual position your pump may have frozen. Steps to protect your pump from frost damage are simple:

Dry Running

Dry running accounted for a huge 18% of pump failures last year and once again is simple to prevent:

Float Switches

Ingress of a foreign object

The ingress of foreign objects can block your pump and cause failures. Once there, some foreign objects are difficult to remove and substances such as sand over a period of time can erode and wear away at your pump causing severe damage.  We advise to install a suction filter. At a starting price of £3.36 (click here) this prevention method is affordable and could save your pump in the long run.

Power Supply

Accounting for a massive 19% of pump failures in the last year power supply issues are certainly one to keep your eyes on! We supply control equipment to prevent damage from power surges, phase failure, current overload and under voltage.

We hope you have found some of these handy prevention hints and tips helpful! In the long run these methods could save your pump from failing.

Should the worst happen, we offer a super fast, Fixed price Collect-Repair-Return service for all makes of pump.

Common Causes of Pump Failures

21 October 2013 by David Critchley


A question we are often asked is: How long will a pump last? This is of course difficult to answer because there are so many factors to consider: Running time, operating conditions, different fluids etc.

However, it is very rare for a pump to fail because it is just ‘worn out’, usually an external factor is the cause of failure - most of which can be prevented. To explain this we have compiled a chart to show the root causes of pump failures we have repaired over the last year.

Common Causes for Pump Failures 2012/13

It must be stressed that these are the root causes of failure, for example a foreign object entering the pump may damage the shaft seal, which may allow water to damage the bearings and eventually short circuit the motor.

The good news is apart from bearing failure, almost all of the above factors can be prevented by correct installation and use of suitable control equipment. In our November blog, we will guide you through some failure prevention methods so you can protect your pump through the winter months. The time of year when these failures are more prone to occur!
