Heavy oil deposits are extremely viscous and require the injection of high pressure, excessive temperature steam to enhance fluidity and allow the oil to be pumped to the floor. In order to boost extraction on this venture, the shopper needed to extend 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 were a specific concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred supplier of some 20 years, for help.

As a end result, the pump is now able to delivering steam at the larger temperatures required. The seal upgrades ensure it meets the latest specs.
Concludes Mike Golds: “We are actually happy with the result of the SAGD pump improve. It has not only achieved the specified manufacturing increase for the customer, but also provided a extra sustainable and cost-effective solution than complete pump replacement. Using fashionable engineering and evaluation, we now have been able to give the prevailing pump a new lease of life and ensure it’ll proceed to carry out properly for many extra years.”
