Obsolete Pump Replacement

Regular pump maintenance is important to ensure the longevity of any pump system, however there may come a time when repair is simply not possible. Replacing a pump can be a challenge, especially when a direct replacement is no longer available. So, how can you replace an obsolete pump?

At North Ridge we not only stock pumps, we can also design and manufacture a bespoke solution to meet your exact requirements, or use our expertise to try to get your existing pump up and running again.

Some models of pumps may have been changed over time meaning once you try to replace it from the existing manufacturer you may find that the existing bell housing, coupling and motor are no longer suitable meaning a complete replacement unit is required leading you to question whether this is the right way forward.

As we are not tied to a particular pump technology or manufacturer, we are able provide you with a solution that will meet your requirements. Our team is available to provide you with aftercare support to ensure the life span of your pump is maximised to its best potential.

Having supported many industries across the globe for over 20 years, our team of process specialists will be able to advise you of alternative solutions for your obsolete pump, and provide training and support to your teams.

Some pump brands where models may have become obsolete over time include:

Q. Our pump is obsolete, are you able to repair it?

A. Pump repair depends on what issue you are having with your pump. Some items we may be able to replace but often, for very old pumps we would recommend a replacement as a new pump may run more efficiently and spare parts be more cost effective.

Q. Can you get spare parts for an obsolete pump?

A. This will depend on the make and model and how long it has been out of production. Contact us to discuss and we will advise you on the best course of action. Some spare parts can become prohibitively expensive over time meaning a replacement pump is the most sensible way forward.

Q. Our pump is obsolete but still working – should we replace it?

A. This depends of your particular application. A new pump may be able to provide greater efficiency and improve your overall profitability, and there may come a time when spares are not available for your pump. Having a plan for replacing your pump will mean you aren’t caught short. Contact us to discuss and we will advise you on the best course of action.

Q. How long do you guarantee to supply spare parts for any pump you manufacture?

A. North Ridge is committed to supplying spare parts for a minimum of 10 years from when a model of pump is discontinued.
