Low NPSH vertical turbine pumps for efficient heat rejection
National Pump Company, a recognized market leader in vertical turbine pumps, offers quick-ship and engineered product solutions for HVAC systems and large cooling applications serving data centers. Backed by more than fifty years of experience in the industrial and commercial market, the company provides pumps designed to meet the performance, efficiency, and reliability demands of critical cooling infrastructure.
National Pump Company’s vertical turbine pumps support effective water circulation, heat transfer, and system cooling in cooling tower and chiller plant applications. Designed around specific flow, total dynamic head, and material requirements, these solutions help improve reliability, reduce maintenance needs, and support long-term energy savings.
The company continues to expand its low NPSH impeller offerings for cooling tower pump applications. Using a low NPSH first-stage impeller can help minimize sump depth and reduce installation costs while allowing customers to pair that first stage with standard hydraulic or high-efficiency impellers in the remaining stages to meet NPSHA requirements and overall performance goals. Current options include the L8HC-S, M14XXHC-S, K20HC-S, and H24MC-S, with additional designs such as the M12HC-S and H14XHC-S broadening engineering flexibility.
The National Pump HVAC, cooling, and data center product portfolio includes 6- to 30-inch hydraulics, flows up to 20,000 GPM, heads to 1,200 PSIG, and motor sizes up to 2,500 HP, along with standard and thrust-balanced hydraulic designs. Material options include cast iron, ductile iron, silicon bronze, aluminum bronze, and 304, 316, and duplex stainless steels to support a wide range of operating conditions and water qualities.
Products from National’s Glendale facility are engineered and manufactured under an ISO 9001 certified quality management system and tested in accordance with Hydraulic Institute compliance standards. National Pump also has additional facilities to meet regional market needs.
