Description

The DAB K 11/500 T 2.2kW Three-Phase Single-Impeller Centrifugal Pump is a heavy-duty centrifugal pump designed for reliable water movement in domestic, civil, agricultural and industrial installations.

Part of the DAB K Single-Impeller range, the K 11/500 T combines a robust cast-iron construction with a three-phase asynchronous motor and single centrifugal impeller. The pump is designed for applications including water supply, irrigation, water transfer, decanting, mixing and general industrial fluid-handling duties where the pumped liquid has characteristics similar to clean water.

The pump body, motor support and impeller are manufactured from cast iron, while the shaft with rotor is stainless steel AISI 303. A carbon/ceramic mechanical seal and EPDM O-ring provide sealing at the hydraulic section.

The K 11/500 T is fitted with a 2.2 kW (3 HP) IE2 three-phase motor, operating at approximately 2,950 rpm. The motor is rated for 3 × 230–400 V at 50 Hz, with a nominal current of approximately 9.3 A at 230 V / 5.4 A at 400 V.

With 2½″ suction and 2″ discharge connections, the pump is suitable for higher-volume water-transfer installations. The K 11/500 T has a maximum operating pressure of 8 bar (800 kPa).

The pump may be installed horizontally or vertically, provided that the motor remains above the pump. The pumped liquid should be clean, free from solids and abrasive substances, non-viscous, non-aggressive and chemically neutral, with characteristics similar to water.
