Submersible Dewatering Pump
Heavy-duty submersible dewatering pumps built to handle open, unmanned sites prone to mud, debris and erratic power supply. The DS, DJ, DJC, TH, TL & JL series offer portable, rugged designs with built-in protection to reduce breakdowns from dry running, single phasing and mechanical jamming.
Product Description
Dewatering sites are usually open to the sky and unmanned, so pumps face large amounts of mud and debris, frequent relocation, rough handling and connections made by unskilled labour. Darling Pumps has built its DS, DJ, DJC, TH, TL & JL range specifically to survive these conditions while continuing to deliver dependable dewatering performance.
The compact DJC models up to 10 HP come with an in-built controller that guards against dry running, overload and mechanical jamming, while the larger DJ and TH models are engineered for high-head pumping of contaminated liquids at ratings up to 100 HP. The lighter TL & JL series adds a modular, run-through-cooled design that is easy to move between flood relief and emergency pumping sites.
