Critical pump failures solved with minimum downtime

, ,

One of the pump producer’s global customers was experiencing pump failures at their facility in China. The situation was critical and the end user demanded a solution ASAP.

Roplan Ltd worked with the pump producers design engineering team in England while Roplan Ningbo worked with their sales and application engineering team in China. Due to different process media and the critical need for solution Roplan Ltd designed and provided 3 sets of samples.

The applications at the end user’s facility were demanding and unique, it was vital to gather information from the failures via analysing the failed pumps and seals before they were disassembled. Of course, the end user could not let this facility sit idle waiting for the pumps to be serviced. To address this, spare pumps were supplied with the trial seals installed along with seals to service existing pumps.

Roplan Ningbo met with the customer at the end-user’s facility to witness the installation of the new pumps, evaluate the failed pumps, collect application data train the pump builders team to install the new design seals and oversee the installation.

The initial trials showed improvement but did not reach the end users expectation. When there was an incident Roplan engineers were in the end-user’s facility within a matter of hours of analyse the failures, gather additional information, discuss potential application problems and install replacement seals to keep the plant running. They then communicated with Roplan Ltd. Based on this design modifications were made and additional samples were installed. The 2nd trial did reach the end users expectation and they plan to standardize one solution throughout their facility.

By utilizing Roplan’s expertise and global support the pump builder was able increase the capabilities of its team in China while satisfying and strengthen the relationship with a key customer.
