Repair or complete maintenance of your Bornemann E4H 1900 progressing cavity pump / mono pump

Is your pump no longer working at full capacity? Has it been left for a long time, or is it rattling, getting too hot or not turning? Would you like to have the pump serviced as a precaution against damage? – Then book our repair and maintenance service!

In the case of a repair, the first thing that matters is a quick diagnosis. Some things you can do, others our trained staff will be happy to check with you. Is there any unusual noise? Is the pump warmer than usual in the area of the stator? Is there any loss of performance or leaks? We recommend suitable measures for this and provide the necessary spare parts and tools. We repair a pump on your premises or in our workshops.

First we dismantle your pump. We then clean and check all parts. Defective or worn parts are replaced or repaired. In most cases, we replace the usual wear parts such as the stator, rotor, joints and seals. If necessary – or at your request – we also replace the drive shaft and coupling rod. Finally, we reassemble the pump and test it according to our strict maintenance guidelines. If you wish, we can give the pump a new coat of paint at the end. Then it will look like new again! We also recommend a new coat of paint to preserve your pump and to be able to quickly recognise any defects or soiling.
Your pump will then have good performance and a long service life again.

Almost like a new pump!
