Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration customer, enabling them to extend production. The pump – a Mather & Platt BB5 – was more than forty years old and had been topic to quite a few post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of excessive strain, excessive temperature steam to enhance fluidity and permit the oil to be pumped to the surface. In pressure gauge octa to spice up extraction on this challenge, the client wanted to extend water temperatures from 90° C to 140° C. However, there have been considerations that the present pump might not be ready to ship this requirement. Nozzle masses were a specific concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most popular provider of some 20 years, for assistance.
Mather & Platt is certainly one of a number of heritage pump manufacturers for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering team undertook a thorough examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used in the heavy oil extraction process. The investigation revealed that the pump had suffered a variety of seal failures over time that had damaged the stuffing field and affected operational effectivity. There had additionally been no maintenance interventions for many years – but the pump had never really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testament to the quality of the original pump that it had continued to operate in such harsh situations and with no common upkeep over such an extended time period. More importantly, it gave us confidence that a thorough overhaul may obtain the desired improvement in performance, saving the client the cost and misplaced production time that can be related to sourcing and installing a new unit.”

Celeros Flow Technology overhauled the SAGD pump and performed 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 face up to the specified temperature increase. As a end result, the pump is now capable of delivering steam at the larger temperatures required. The seal upgrades ensure it meets the most recent specs.
Concludes Mike Golds: “We are actually pleased with the finish result of the SAGD pump improve. It has not solely achieved the specified production improve for the shopper, but in addition provided a more sustainable and cost-effective solution than total pump replacement. Using modern engineering and evaluation, we have been in a place to give the existing pump a new lease of life and guarantee it’ll continue to carry out nicely for a lot of extra years.”
