The WEDA 04S self priming portable pump has a maximum flow of 270l/min. This small electric pump weighs 10kg and can handle up 25mm of solids. The WEDA 04S is:
• Tough against sand, mud and trash;
• Designed with a vortex cast iron impeller and triple seal system;
• Particles and debris up to 25 mm can go through the pump housing with minimal wear;
• Same motor protection as for WEDA 04/08.
The new Atlas Copco WEDA Small Range pumps are portable, light weight and easily maintained. They provide fast and efficient dewatering for a wide variety of applications, including:
Atlas Copco have a global reputation for the build quality of their products. That level of excellence is evident in all the components
of the WEDA range of submersible pumps, such as its unique sealing system, nitrile rubber linings for all wetted parts, Class F insulated stators with thermo switches in all windings and hardened chrome clog-free impellers.
These individual parts add up to a lot, but what also contributes to the Pump’s superior performance are value-added features. These include rotation and phase failure protection, which prevents the risk of the impeller rotating in the wrong direction and stops
the pump in the event of phase failure. They also come equipped with reinforced cable entry points and lightweight, high efficiency motors that are available in a wide-range of voltages. For added peace of the mind, the motors are protected from overheating by
an overload/over-current auto stop function.
WEDA pumps are easy-to-install, offer long intervals between services and are designed with ease of maintenance in mind. Their modular construction simplifies separation of the principal components and all stainless steel fastenings are the same size. This allows one tool to complete the operation. Seals, impellers and other parts can be changed in minutes. For larger pumps in the WEDA range an Instant Service Pack represents the optimum service solution by providing mechanical seals, bearing oil and housing oil for easy change at the work site.
The pumps feature an external plug for grease filling and offer a variety of connection options, with the flexibility of changing the flow direction from 90-180 degrees.
Positioning a pump into water in a safe and efficient manner is critical to achieving a straightforward dewatering operation.
An example of this portability is the fact that you can even achieve a flow of around 1300 litres per minute with a pump that only weighs 20 kg. Some models are up to 15 percent lighter than comparable products in their class; which makes a world of difference when you’re on the water’s edge and need to start pumping quickly.
The improved aluminum alloy construction provides higher corrosion resistance over a wide range of applications. Within the product range, units are capable of handling suspended solids of up to 2” (50 mm) dimension through the pump, dependent upon
the model and specification.
Pump operation is not about pumping water at any cost, so energy efficiency has not been ignored. Overall, the WEDA submersible pump range can consume up to 20 percent less energy than comparable models.
