Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil recovery buyer, enabling them to extend production. The pump – a Mather & Platt BB5 – was more than forty years previous and had been subject to quite a few post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of excessive strain, high temperature steam to enhance fluidity and permit the oil to be pumped to the surface. In order to spice up extraction on this venture, the client wanted to increase water temperatures from 90° C to 140° C. However, there have been concerns that the present pump may not have the ability to ship this requirement. ไดอะแฟรม ซีล were a selected concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most well-liked supplier of some 20 years, for assistance.
Mather & Platt is considered one of several heritage pump brands for which Celeros Flow Technology offers full lifecycle support1. Their aftermarket engineering group undertook a thorough examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used within the heavy oil extraction process. The investigation revealed that the pump had suffered numerous seal failures over time that had broken the stuffing field and affected operational efficiency. There had also been no maintenance interventions for decades – however the pump had never really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testomony to the standard of the unique pump that it had continued to operate in such harsh conditions and with no regular maintenance over such a long time period. More importantly, it gave us confidence that a thorough overhaul might obtain the specified improvement in performance, saving the client the cost and lost production time that can be related to sourcing and installing a new unit.”

Celeros Flow Technology overhauled the SAGD pump and carried out a mechanical seal upgrade and Plan 23 seal flush to optimize pump performance. In addition, finite component analysis was undertaken to confirm that the nozzle masses would withstand the specified temperature enhance. As a outcome, the pump is now capable of delivering steam on the larger temperatures required. The seal upgrades ensure it meets the newest specifications.
Concludes Mike Golds: “We are really happy with the end result of the SAGD pump upgrade. It has not solely achieved the specified production improve for the customer, but also provided a more sustainable and cost-effective answer than total pump alternative. Using trendy engineering and analysis, we’ve been in a position to give the present pump a model new lease of life and ensure it’ll proceed to perform well for so much of extra years.”
