Description

The DAB K 40/200 T is a 3 kW three-phase, single-impeller centrifugal pump designed for reliable water transfer and circulation in domestic, commercial, agricultural and industrial installations.

The K Single-Impeller range is designed for applications including water supply, irrigation, decanting, mixing and general water-transfer duties. The K 40/200 T combines a durable cast-iron pump body and motor support with a technopolymer impeller, AISI 303 stainless-steel shaft and carbon/ceramic mechanical seal.

The pump is equipped with a closed asynchronous three-phase motor with external ventilation cooling and ball bearings designed for durability and low-noise operation. The exact 60146050 version has a nominal motor output of 3 kW (4 HP), with a maximum input power of approximately 3.5 kW. It operates from a 3 × 230–400 V, 50 Hz supply.

The hydraulic performance of the K 40/200 reaches approximately 41.3 metres of head at zero flow, with the published performance curve showing approximately 41 m at 4.8 m³/h, 40.5 m at 6 m³/h, 40 m at 7.2 m³/h, 39 m at 9 m³/h, 38.8 m at 9.6 m³/h, 38 m at 10.8 m³/h, 37 m at 12 m³/h, 33.5 m at 15 m³/h and 29 m at 18 m³/h. The actual duty point depends on the complete installation and system resistance.

The pump can be installed horizontally or vertically, provided that the motor remains above the pump. It is intended for clean liquids that are free from solids and abrasive substances, non-viscous, non-aggressive, non-crystallised and chemically neutral, with characteristics similar to water.
