National Pump Company to Showcase Vertical Turbines at WEFTEC

National Pump Company (NPC) will highlight its latest advancements in vertical turbine pump technology at the WEFTEC 2026 (September 28–30, 2026) exhibition in New Orleans. Showcasing its capabilities for the municipal water and wastewater industry, NPC will introduce its new 28-inch high-performance pump models, the H28MC and H28LC. Designed to bridge the gap between the company's existing H24 and H30 series, these high-volume pumps operate at 1,180 RPM and deliver efficiencies of up to 87 percent at their Best Efficiency Points. The H28MC can achieve 14,750 gallons per minute at 143 feet per stage, while the H28LC delivers 13,250 gallons per minute at 131 feet per stage.

NPC's broader municipal product portfolio includes 6-inch to 30-inch hydraulics capable of handling flows up to 20,000 gallons per minute, heads up to 2,000 feet, and power ratings reaching 2,000 horsepower. The pumps can be configured for a variety of tasks, from short-set water treatment applications to deep-well rural water supply. To accommodate diverse operating conditions and harsh environments, the company offers multiple material options, including cast and ductile iron; silicon, aluminum, and tin bronzes; as well as 304, 316, and duplex stainless steels. NPC's Glendale manufacturing facility is ISO 9001:2015 certified, and its pumps are available with NSF 61 and NSF 372 certifications to meet stringent municipal safety standards.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

Vertical turbine pumps (VTPs) are specialized multi-stage centrifugal pumps widely utilized in municipal water distribution and deep-well extraction due to their ability to generate massive flow rates and extreme pressure heads from a compact vertical footprint. To achieve capacities of up to 14,750 gallons per minute at 143 feet of head per stage, the hydraulic design of the pump bowl and impellers must be precisely engineered. For the new H28 series, engineers utilized computational fluid dynamics (CFD) flow simulation to maximize hydraulic efficiency up to 87%, and finite element analysis (FEA) to optimize the strength-to-weight ratio of the cast components. This ensures the massive drive motors can operate at peak efficiency without causing destructive vibrational harmonics or cavitation during continuous, high-volume municipal water transport.
