After the successful introduction of the 6” DPU 17 and 30, DP-Pumps now adds two high capacity borehole pumps to their DPU series; the DPU 48 and 60. The extension of the product range adds capacity as well as higher efficiency to the DPU series. The new pumps achieve a 5% extra efficiency making the pump work at a maximum efficiency rate of 80%. By adding two high capacity pumps to the DPU series, the company now offers a complete range of durable and efficient stainless steel borehole pumps.
Stainless steel for durability
Equal to the other pumps in the DP-Pumps product range, all wetted parts of the DPU-series are made of stainless steel for a long life span. Heavy sheet metal is used for the hydraulic parts to make them resistant to the wear caused by sand. The DPU can handle clean, low viscous, non-aggressive liquids. The DPUS is made of high grade stainless steel AISI 316 and can handle more aggressive liquids, like brackish water.
Innovation
The Dutch company extended their machine park with the latest laser welding technology, which enabled the manufacturing of an innovative impeller and stage casing. The hydraulically favourable design enables the pumps to achieve efficiencies of 80%, resulting in low energy costs over the entire life span of the pump. The DPU 48 and 60 realize, depending on the number of stages, a maximum pressure of 730 m / 2395 feet and a maximum capacity of 93 m3/h/ 410 GPM. The pump is available in both 50 and 60 Hz versions.
Applications
The DPU is designed for well diameters of 150 mm (6”) or more. The DPU can be used for irrigation systems, general and domestic water supplies, fire protection, groundwater lowering, pressure boosting, cooling water cycles and industrial applications. However, the DPU is also applicable in horizontal installations, as for example in fountains and water reservoirs. An exchangeable adapter provides a variety of pipe connection options, offering customers three threaded and three flanged connection types, each without having to undo the tie bolts. As a result, customers only have to stock a single pump variant, which allows them to reduce their pump and spares inventories.
