DARLING PUMPS SUBMERSIBLE PUMPS
Darling Pumps is a leading Indian manufacturer of submersible pumps, ISO 9001:2015 certified, with over 42 years of experience designing SMART pumping solutions for construction, mining, municipal, industrial and agricultural applications. Pankaj Enterprises supplies the full Darling Pumps submersible range — dewatering, waste water & non-clog, slurry, and clear & raw water pumps — backed by genuine spares and after-sales support.
Clear and Raw Water Pumps
Darling's pioneering open-well clear-water submersible range, backed by an Indian patent, consists of the S (single stage) and M (multi stage) series — compact enough to be installed vertically or inclined, with a head of up to 140 m in a maximum of four stages.
Product Description
The S and M series were among the first of their kind in India and remain popular for both agricultural and industrial applications thanks to their compact size and ability to be installed at an angle where vertical installation is not practical. Darling's raw water range, built around the SVT platform, extends this reliability to river and sea water pumping and offers a strong, sturdy, user-friendly alternative to conventional vertical turbine pumps.
Both ranges use a highly efficient impeller that delivers more output in fewer stages, paired with a dry motor rated to withstand wide voltage fluctuations and an extra heavy-duty SS shaft for tough site conditions.
Applications
- Pumping from underground tank to overhead tank in housing & commercial complexes
- Hotels & hospitals
- Fountains, waterfalls & landscaping
- Agriculture & irrigation projects
- Village & municipal water supply
- River water pumping
- Fire fighting
- Sea water pumping (raw water range)
