DAB K Series Twin Impeller Centrifugal Cast Iron Pumps Manual

The DAB K Series Twin Impeller centrifugal pumps are engineered for high head applications, offering reliable and consistent pressure for domestic, commercial, and agricultural systems. Built with a durable cast iron body and motor support, these pumps are ideal for installations requiring powerful water transfer from rivers, tanks, or dams, particularly where pressure must be maintained across long pipe runs or height elevations.

This manual model is designed for integration with external pressure switches, controllers, or pressurisation systems. The twin impeller design provides greater pressure output than single impeller models, making it ideal for irrigation, lawn watering, and tank-to-building pressure boosting.

With carbon/ceramic mechanical seals, stainless steel shaft, and either technopolymer or cast iron impellers (model dependent), the pump is built for long service life with minimal maintenance. Its asynchronous, air-cooled motor ensures silent and efficient operation, and includes thermal overload protection on single-phase units.
