Reliable pump solution
Most borehole pumps form the elementary basis of a process. It is therefore very important that you can rely on the quality of the pump. The 4" DPU has a solid stainless steel basis which preserves the water quality and stands for a long life cycle. It also makes the pump suitable for operating in a wide range of applications:
- Domestic and general water supply
- Irrigation systems
- Groundwater lowering
- Pressure boosting
- Fountains
- Air-conditioning systems
- Cooling water circulation
- Fire protection / Sprinklers
- Industrial applications
Advantages
- Easy maintenance; limited number of parts
- NBR / Buna N elastomers: suitable for a large range of applications
- Heavy sheet metal for a longer life-cycle
- Stainless steel suction casing for longer life-cycle, adaptable to motor flange size (4”or 6”)
- Axial bearing mounted for less wear; less service and a longer life-cycle
