Atlas Copco has introduced a range of smaller WEDA portable pumps for dewatering. The new WEDA04 and WEDA08 models provide drainage pumping, the WEDA08S is designed for sludge pumping and the WEDA04B for low-suction pumping. The WEDA04 is equipped with a 400-watt electric motor and the WEDA08 features a 750-watt motor.
A polyurethane semi-vortex impeller on these models reduces the risk of clogging, and both models are fitted with built-in motor protection, high-torque capacitor and a three-terminal automatic cutoff to prevent motor overload and dry burning. The WEDA08S sludge pump is specifically designed for difficult sand and mud applications. Equipped with a 750-watt motor and a vortex cast-iron impeller, particles and debris up to 25 millimeters can go through the pump housing with minimal wear. All of the new models were designed with an outer jacket for cooling; thermo protection keeps the pumps running safely under a variety of conditions. If the pump has stopped automatically due to overheating or overload/over-current, it will automatically restart after cooling down. A triple shaft seal assures long life, and the semi-vortex wet end minimizes maintenance. All feature dry running capability.
