DAB Vertical Multistage Pumps

DAB vertical multistage pumps are designed for high-efficiency water transfer in applications where consistent pressure, reliability, and compact installation are essential. Featuring multiple impellers arranged in a vertical configuration, they are capable of generating high pressures while maintaining smooth, energy-efficient operation and low noise levels. Many models incorporate close-coupled designs, precision-engineered hydraulic components, and high-quality mechanical seals to ensure dependable performance under continuous duty conditions and extended service life.

Their vertical design significantly reduces installation footprint, making them ideal for space-restricted environments. Constructed from corrosion-resistant materials such as stainless steel for enhanced durability, they are widely used in pressure boosting, water supply, HVAC systems, irrigation, and a range of industrial processes, providing a robust and space-saving solution for demanding applications.

DAB Vertical Multistage Pump Ranges

NKV
Series

The NKV vertical multistage centrifugal pump series is crafted for medium to high-demand water systems. Ideal for pressurisation, boiler feed, fire‑fighting, sprinkler systems, and water purification, it delivers flows from 4 to 118 m³/h and head pressures up to 231 m. Internal liquid-contacting components are made from micro-cast AISI 304 stainless steel or high-strength cast iron, with maintenance‑free cartridge mechanical seals accessible without removing the motor (on ≥5.5 kW models).

KVC
Series

DAB’s KVC vertical multistage line targets smaller to mid‑sized water supply units. Typical applications include boosting systems, tank filling, fire‑fighting, irrigation, condensate transfer, and cooling circuits. It handles flows of 50–200 L/min with heads up to 113 m and withstands operating pressures up to 12 bar (1.2 MPa). Compliance with EN safety standards allows liquid temperatures from 0 °C to +35 °C for domestic and up to +40 °C for other uses.

KVCX
Series

The KVCX variant complements the KVC line with enhanced construction and corrosion resistance. It shares the same operating envelope 50–200 L/min and up to 113 m head but builds in a stainless-steel delivery port and liner, plus technopolymer suction body with metallic threaded inserts. Carbon/ceramic mechanical seals fitted on stainless-steel drive shafts, combined with an IP rating conducive to demanding installations, make the KVCX configuration particularly resilient.

NKV-E Hydro-boost Series

DAB also offers the NKV-E extension to the standard NKV line, optimised for boiler feed and high-pressure applications. While detailed info is less accessible, these models mirror the standard NKV hydraulics and performance (flows up to ~118 m³/h and heads above 200 m), but are designed for use in heating and cooling systems and sprinkler installations, with emphasis on energy efficiency and high operating.
