The new range has undergone a top-to-toe design overhaul, resulting in new pumps that can offer up to 20% overall reduction in power consumption compared to previous models; combined with greater efficiency, simplified maintenance and increased capacity.
The WEDA+ range comprises five models: the WEDA 50, with normal and high head variants, and the WEDA 60+, available in normal head, high head and super high head configuration. Delivering enhanced performance and extreme portability, the Super High Head WEDA 60+ is 15% smaller and 20% lighter than other pumps in its class. The latest pumps offer flow rate capabilities of 1,020 to 2,425L/min (61 to 146m3/h) and a maximum head of up to 69m.
Atlas Copco has introduced rotation control and phase failure protection across all WEDA+ models to prevent the risk of the impeller rotating in the wrong direction; which stops the pump in the event of phase failure. In addition, the entry system can accommodate a wider range of cable configurations, with an advanced motor design offering higher efficiency and reduced start current. Meanwhile, the drive train features double row bearings for improved lifetime service. For added durability, all models are constructed with an improved aluminium alloy that provides high corrosion resistance in even the toughest applications.
Wim Moors, vice-president pumps at Atlas Copco Portable Energy, said: “The new WEDA+ pumps are easy-to-move and install in a wide range of dewatering applications. We have taken our portable and powerful electric submersible offering to the next level by focussing on efficiency and new features that will simplify the customer experience and enhance their productivity.”
Simple service is another feature of the new range. The modular construction simplifies separation of principal components and all stainless-steel fastenings are the same size. This effectively means that one tool can be used to change all seals, impellers and other parts; in just a matter of minutes.
All the new WEDA+ models incorporate the features associated with the long-established WEDA range of medium and large pumps, including an advanced sealing system, optional automatic level control, adjustable wear-resistant nitrile rubber diffusers and hardened high chrome clog-free impellers.
