Borehole Pumps (6 ines DPU)
Groundbreaking efficiency and durability
 |
|
DP-Pumps, introduces the 6” borehole pump: DPU. By using our experience in hydraulics and the latest developments in laser welding technology, the hydraulic assembly of the DPU assures very high efficiency rates.
When life-cycle costs are important to you, the DPU is the right choice. The use of stainless steel results in a light, wear resistant pump. The application of NBR / Buna N for the sealing of the pump makes the pump suitable for a wide range of applications.
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
- Pipe adapter for easy adaptation to other pipe dimensions (threaded or flanged)
- Easy maintenance; limited number of parts
- Suction strainer can be cleaned and / or replaced without disassembling the hydraulic package
- Exchangeable spring-loaded non-return valve for easy maintenance
- NBR / Buna N elastomers: suitable for a large range of applications
- Heavy sheet metal for a longer life-cycle
- Hydraulics are laser welded for efficiency; more hygiene and a longer life-cycle
- Stainless steel investment cast 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

- Suction casing: motor connections 4” or 6” (NEMA standard)
|
| Material |
- All wetted parts: stainless steel AISI 304 (DPU) or 316 (DPUS)
- Elastomers: NBR (Buna N)
|
| Pumped medium |
- Clean, low viscous, non-aggressive liquids without solid particles or fibres
- The DPUS is made of high grade stainless steel AISI 316 and therefore can handle more aggressive liquids
|
| Maximum temperature medium |
- 60° C. (140° F.)
- Please consult technical documentation of motor supplier for the maximum allowable medium temperature
|
| Maximum sand content |
|
Options
- DPUS-series (SS AISI 316) for more aggressive fluids
