Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration customer, enabling them to increase manufacturing. The pump – a Mather & Platt BB5 – was greater than forty years old and had been topic to quite a few post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of high strain, excessive temperature steam to enhance fluidity and allow the oil to be pumped to the surface. In order to boost extraction on this project, the client wanted to extend water temperatures from 90° C to 140° C. However, there were concerns that the existing pump might not be capable of ship this requirement. Nozzle loads had been a specific concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most well-liked provider of some 20 years, for help.
Mather & Platt is considered one of a number of heritage pump manufacturers for which Celeros Flow Technology provides full lifecycle support1.

In addition, finite element analysis was undertaken to confirm that the nozzle masses would face up to the specified temperature enhance. As a result, the pump is now capable of delivering steam on the higher temperatures required. The seal upgrades ensure it meets the newest specs.
Concludes Mike Golds: “We are actually happy with the result of the SAGD pump upgrade. It has not solely achieved the desired production improve for the shopper, but additionally offered a more sustainable and cost-effective resolution than total pump substitute. Using เกจวัดแรงดันน้ำดิจิตอล and evaluation, we now have been in a position to give the prevailing pump a brand new lease of life and ensure it’s going to proceed to carry out well for lots of extra years.”
