Horizontal, multi-level, highly-efficient and non self-priming high-pressure multistage centrifugal pump with offline connections.
This non self-priming high-pressure multistage centrifugal pump has a compact design and is particularly efficient and user friendly. The standard-mounted IEC standard motor equipped with a PTC sensor, and our proprietary hydraulics ensure extremely high efficiency. It can be equipped with a stuffing box packing upon request, which can be swapped out without dismantling the pump thanks to its exclusive Twinner System packing construction.
Applications
The pump is suitable for use in professional irrigation/agriculture, water supply, pressure boosting, fire fighting and in the area of heating, air conditioning, cooling.
