A new line of pump tanks for central chillers and cooling towers has pump suction legs that are angled to prevent vortexing and pump cavitation, allowing for operation at lower fill levels, thereby economizing water and chemical usage.

A new line of pump tanks for central chillers and cooling towers has pump suction legs that are angled to prevent vortexing and pump cavitation, allowing for operation at lower fill levels, thereby economizing water and chemical usage. In addition, these stainless-steel or epoxy-coated carbon-steel tanks from Mokon, Buffalo, N.Y., have close-coupled, non-overloading, centrifugal pumps; low-pressure and low-level shutoff switches; and a NEMA 12 electrical junction box that protects against dust. A suction butterfly valve streamlines maintenance by enabling pump replacement without draining the tank.
