Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration customer, enabling them to increase production. The pump – a Mather & Platt BB5 – was greater than forty years old and had been topic to numerous post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of high strain, high temperature steam to enhance fluidity and permit the oil to be pumped to the floor. In order to boost extraction on this venture, the shopper wanted to increase water temperatures from 90° C to 140° C. However, there have been considerations that the prevailing pump may not be succesful of deliver this requirement. Nozzle loads have been a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most popular provider 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 an intensive 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 quantity of seal failures over time that had damaged the stuffing field and affected operational effectivity. There had also been no upkeep interventions for decades – however the pump had by no means really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testament to the quality of the unique pump that it had continued to operate in such harsh circumstances and with no regular upkeep over such a protracted time period. digital pressure gauge , it gave us confidence that a thorough overhaul could obtain the desired improvement in performance, saving the customer the price and lost production time that can be related to sourcing and installing a model new unit.”

Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal improve and Plan 23 seal flush to optimize pump performance. In addition, finite element analysis was undertaken to verify that the nozzle loads would face up to the desired temperature enhance. As a outcome, the pump is now able to delivering steam on the larger temperatures required. The seal upgrades guarantee it meets the most recent specs.
Concludes Mike Golds: “We are actually happy with the outcome of the SAGD pump improve. It has not only achieved the specified production increase for the shopper, but in addition offered a more sustainable and cost-effective solution than whole pump substitute. Using trendy engineering and evaluation, we have been able to give the existing pump a new lease of life and guarantee it’ll proceed to perform properly for so much of extra years.”
