Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil restoration buyer, enabling them to increase manufacturing. The pump – a Mather & Platt BB5 – was greater than forty years previous and had been subject to numerous post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of high stress, high temperature steam to enhance fluidity and permit the oil to be pumped to the floor. In order to spice up extraction on this venture, the client wanted to increase water temperatures from 90° C to 140° C. However, there were issues that the prevailing pump could not be ready to deliver this requirement. Nozzle loads were a specific concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most popular 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 team undertook an intensive examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used within the heavy oil extraction course of. The investigation revealed that the pump had suffered a number of seal failures over time that had damaged the stuffing box and affected operational efficiency. There had additionally been no maintenance interventions for decades – but the pump had by no means really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testomony to the standard of the original pump that it had continued to function in such harsh circumstances and with no common upkeep over such a protracted time frame. More importantly, it gave us confidence that a thorough overhaul might obtain the desired improvement in efficiency, saving the client the price and lost manufacturing time that can be related to sourcing and putting in a brand 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 element analysis was undertaken to confirm that the nozzle loads would stand up to the specified temperature increase. As เกจวัดแรงดันแบบแห้ง , the pump is now capable of delivering steam at the greater temperatures required. The seal upgrades ensure it meets the newest specs.
Concludes Mike Golds: “We are actually pleased with the finish result of the SAGD pump upgrade. It has not only achieved the desired manufacturing improve for the client, but in addition supplied a extra sustainable and cost-effective resolution than whole pump replacement. Using trendy engineering and analysis, we have been capable of give the present pump a brand new lease of life and ensure it’ll continue to carry out properly for many more years.”
