Description

The DAB K70/300 T is a robust, high-performance double-impeller centrifugal pump designed for water supply, pressure boosting, irrigation and general water-transfer applications.

With its twin-impeller configuration, the pump is capable of producing high delivery pressures and is particularly suitable for pressurisation units, pressure-vessel filling, sprinkler irrigation and general water-supply systems.

The pump is suitable for domestic, civil, commercial, industrial and agricultural water installations, making it a versatile solution for applications where dependable water pressure and reliable pumping performance are required.

The K70/300 T features a cast-iron pump body and motor support, technopolymer impellers, stainless-steel shaft and carbon/ceramic mechanical seal. Its enclosed asynchronous three-phase motor is externally ventilated and fitted with oversized ball bearings to provide reliable operation, durability and reduced operating noise.
