What does it take to make a centrifugal pump more dependable and fail-safe?
How can the centrifugal pumps that help run your operation be protected from damage caused by breakdowns?
Wouldn't you like the security of knowing that pumps won't get damaged because they run at no-flow condition?

Centrifugal pumps need the benefit of the all-new Opti-Valve Casing Relief System. It’s a pre-engineered package of components designed to protect centrifugal pumps from damage caused by operating at no-flow condition.
Centrifugal pumps are truly interesting machines. Simple, reliable and easy to build, they have only one rotating part and one or two bearings. One can do things to a centrifugal pump that would stall other types of pumps, such as blocking the discharge flow. But, like the old philosopher said, “There ain’t no free lunch.” Some trade-offs must be made.
Centrifugal pumps must be purged of air and they are non-self priming, to name a couple of trade-offs. Also when centrifugal pumps are operated at no-flow conditions, fluid becomes “trapped” within the pump cavities and the mechanical agitation of the rotating impeller begins heating the fluid and then the pump itself.
The fluid’s temperature rises until the trapped fluid may boil and drive up system pressures. Enough heat is transferred to the metal that paint blisters and seals fail. Damage can get expensive quickly. The solution is to prevent the pump from operating at a no-flow condition.

That's the job of the Opti-Valve Casing Relief System!
