Atlas Copco expand small submersible pumps range

Company adds WEDA 04S to its small rental and construction pumps portfolio

ATLAS Copco Portable Energy have strengthened their line-up of small submersible pumps for the light construction and general equipment rental sectors with the launch of WEDA 04S – a 0.4kW on-site sludge/trash pump with a maximum flow of 270 litres/min and maximum head of 10.5m.

Complementing the WEDA range of under 1kW single-phase drainage, sludge and residual pumps, the WEDA 04S pump has a cast iron vortex impeller that is able to pump dirty water and handle solids up to 25mm in size.

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 more reliability and run-dry capabilities. Its low weight (10kg) and compact dimensions – 372.5mm (height) and 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,’ explained 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.’

The Atlas Copco WEDA small pumps range includes: WEDA 04 and WEDA 08 drainage pumps; WEDA 04B residual pump that draws water down to 1mm; and sand- and mud-resistant WEDA 08S sludge pump. The company also offers a range of kits, hoses and coupling accessories for the WEDA pumps.

The CE-compliant 50Hz variant of the WEDA 04S is now available, while a CSA-UL approved 60Hz version will be available in early 2014.
