Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil restoration customer, enabling them to increase manufacturing. The pump – a Mather & Platt BB5 – was more 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 boost extraction on this challenge, the customer wanted to extend water temperatures from 90° C to 140° C. However, there have been considerations that the prevailing pump could not be ready to ship this requirement. Nozzle masses were a particular concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most popular supplier of some 20 years, for help.
Mather & Platt is one of a quantity of 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 in the heavy oil extraction course of.

Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal upgrade and Plan 23 seal flush to optimize pump efficiency. In addition, finite factor analysis was undertaken to verify that the nozzle loads would face up to the desired temperature improve. As a result, the pump is now able to delivering steam on the higher temperatures required. The seal upgrades ensure it meets the newest specifications.
Concludes Mike Golds: “We are actually happy with the finish result of the SAGD pump upgrade. It has not solely achieved the desired production enhance for the customer, but additionally offered a extra sustainable and cost-effective resolution than total pump substitute. Using ร้านซ่อมเครื่องวัดความดันโลหิต and analysis, we’ve been in a position to give the existing pump a new lease of life and ensure it will continue to carry out well for a lot of extra years.”
