Atlas Copco adds WEDA 04S to its line-up of small rental and construction pumps

The WEDA 04S is a 0.4 kW on-site sludge / trash pump with a maximum flow of 270 lpm and a maximum head of 10.5m. It complements the WEDA line of under 1 kW single-phase drainage, sludge and residual pumps released last year.

The WEDA 04S has a cast iron vortex impeller that is able to pump dirty water and handle solids up to 25mm in size. This makes the pump a practical choice for dewatering sewage in flooded building basements or on construction sites, removing rainwater from sandy or muddy ditches and excavation sites, or getting rid of unwanted water during maintenance of utility manholes.

The pump is robust and easy to maintain thanks to its triple seal system (double mechanical shaft seals constructed from silicon carbide with an additional lip seal). Thermal protection gives the motor additional reliability and run-dry capabilities. And its low weight (10kg) and compact dimensions
(372.5mm H x 241mm diameter) ensure the pump is easily portable from one dewatering task to the next.

“Our product range already included the WEDA 04, a 0.4 kW drainage pump, but we received requests for a small pump that could also handle solids. Our answer is the WEDA 04S,” explains Abet Cantuba, Product Marketing Manager Pumps for Atlas Copco Portable Energy. “In the future, we plan to expand our sludge / trash pump range to include larger kW power nodes which will be able to pump higher flows and handle larger sizes of solids. This will be important for applications in mines and municipal sewers.”
