Atlas Copco develops new dewatering pumps

Atlas Copco has unveiled new diesel powered portable dewatering pumps.

The move is a major expansion of its existing dewatering pump range, and include new four, six, and eight inch dry-prime units.

This PAS diesel driven range is designed for harsh working environments where ready access to power is not available.

According to Atlas Copco, the PAS dry-prime pumps "are best suited for transporting or lifting water with abrasive solids in suspension" such as those found in the mining industry.

Applications include dewatering at mine sites, floodwater or stream diversions and sewage bypass for industries. 

"The PAS combines high performance with minimum operating expense. For rental companies and dewatering contractors, this is extremely important as it enables them to get a faster return on equipment acquisition costs, which is exactly what they require to stay competitive," Atlas Copco's product marketing manager pumps, Abet Cantuba, said.

The PAS 4, PAS 6, and PAS 8 pumps have an operating flow range of between 50 to 600 cubic metres per hour, with a maximum head of up to 37 metres.

Their solids handling capacity reaches up to 76 millimetres.

"An environmentally friendly, oil-free vacuum pump priming system, which automatically removes air from the water, ensures uninterrupted, unsupervised operation," Atlas Copco added.

They are driven by a Kubota engine, while a large cooler capacity allows for continuous operation even at high ambient conditions.

The PAS pumps come with a skid fuel tank that allows the pump to run for days without refuelling.

A straight-forward design and basic controller interface ensure easy operation whilst large panels provide easier maintenance.
