Double-welded pump tanks are available in either stainless steel or epoxy-coated carbon steel construction for long-life, corrosion-resistant performance. The tanks feature high-efficiency, close-coupled, non-overloading centrifugal pumps designed to meet process and refrigeration requirements for optimal flow and pressure. Pump suction and discharge piping trim are sized appropriately, thus eliminating excessive pressure drop while maximizing flow to the process. Low-pressure and low-level shut-off switches provide overall protection to the tanks' pumps and motors. All pump tanks include a NEMA 12 electrical junction box that facilitates a single-point electrical connection and protects electronics against dust and other harmful debris. Pump suction legs are angled to prevent vortexing and pump cavitation, allowing for lower-level operation that economizes water and chemical usage. Fill, overflow and dual-drain connections are provided on the complete pump tank line.
