Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil recovery customer, enabling them to extend production. The pump – a Mather & Platt BB5 – was greater than 40 years old and had been topic to numerous post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of high stress, high temperature steam to improve fluidity and permit the oil to be pumped to the surface. In order to boost extraction on this venture, the client wanted to increase water temperatures from 90° C to 140° C. However, there have been issues that the existing pump might not be in a position to ship this requirement. Nozzle hundreds were a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred supplier of some 20 years, for help.
Mather & Platt is considered one of a number of heritage pump manufacturers for which Celeros Flow Technology offers full lifecycle support1. Their aftermarket engineering group undertook a radical 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 selection of seal failures over time that had damaged the stuffing field and affected operational efficiency. There had additionally been no maintenance interventions for decades – but the pump had never actually failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testament to the standard of the original pump that it had continued to operate in such harsh conditions and with no regular maintenance over such a protracted time frame. More importantly, it gave us confidence that a thorough overhaul may obtain the specified enchancment in performance, saving the client the fee and lost production time that could be associated with sourcing and installing a brand new unit.”

Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal improve and Plan 23 seal flush to optimize pump efficiency. In addition, finite factor analysis was undertaken to substantiate that the nozzle masses would face up to the desired temperature improve. As pressure gauge octa , the pump is now capable of delivering steam at the greater temperatures required. The seal upgrades guarantee it meets the newest specs.
Concludes Mike Golds: “We are actually pleased with the end result of the SAGD pump improve. ไดอะแฟรม ซีล has not only achieved the desired production improve for the customer, but additionally supplied a extra sustainable and cost-effective answer than whole pump replacement. Using fashionable engineering and analysis, we’ve been in a position to give the present pump a model new lease of life and guarantee it’ll continue to perform nicely for lots of extra years.”
