Description

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

Powered by a 5.5 kW / 7.5 HP three-phase motor, the K70/300 T is well suited to domestic, commercial, civil, industrial and agricultural water systems where reliable pressure and high-head pumping performance are required.

The double-impeller configuration provides excellent pressure performance while maintaining a compact and robust pump design. The pump incorporates a cast-iron pump body and motor support, technopolymer impellers, stainless-steel shaft and carbon/ceramic mechanical seal.

The motor is an enclosed asynchronous three-phase motor with external ventilation cooling. The design incorporates oversized ball bearings to provide reliable operation, durability and reduced operating noise.

The K70/300 T is suitable for fixed horizontal or vertical installation, provided the motor remains above the pump. It is designed for pumping clean water and liquids with characteristics similar to water.
