ENGIE - AVF-X RANGE

Please detail the purpose and precise technical application for this project.

"A bank of stainless-steel mag-drive pumps for 96% Sulphuric Acid transfer from Bulk Storage Tank to Process were constantly being repaired and not performing as originally intended. We carried out a pipework survey taking elevation and pressure readings to determine why the pumps weren’t performing. After accounting for density adjustment, the pumps were running very close to closed valve pressure due to the fact the pumps were originally selected severely left of curve to accommodate a specific gravity of 1.84 and ensure the magnets were not over-loaded! This meant the pump was grossly oversized for the application."

Please detail the benefits to the customer, including energy efficiency, cost, ease of use, future maintainability.

"Our recommendations were implemented by the customer saving him many thousands of pounds repairing the original inefficient and poorly selected pumps, though the biggest cost saving is his increased production due to the plant not suffering from unscheduled down-time due to pump failure. But not only will the customer save on costly repair bills and down-time, but they will also benefit from a very significant reduction in energy consumption of 20%, as efficient pumps operating near their B.E.P (best efficiency point) have now been installed. The main benefit for the client is the long-term reliability this solution will provide."

Client Testimonial

Steve A, Engie

"I really can’t praise Crest enough. your understanding of our requirements was excellent. The recommendations made have now been implemented on two of our systems, we have seen a marked improvement to both. The improvement to one of our systems (acid transfer) made such a difference that we have purchased another 3 pump units on the back of it. I would have no doubt in recommending your services, so I give you a 10/10."
