Non Clog and Wastewater Pumps

Today, water treatment, its conservation, recycling & its reuse have assumed greater significance. Thus, the demand for pumping / treating waste water is going up steadily. The present methods are also more versatile & thus demand greater reliability as far as pumping needs are concerned. Darling Pumps, having worked effectively in this sector, can offer a reliable & effective wastewater pump manufacturer solution.

As we have been working in this sector for over 4 decades, we have made our pump designs more adaptable to challenges in this sector… not only in terms of capacities but also in terms of MOC’s & many significant add-on features.

Non Clog and Wastewater Pumps

Non-clog submersible pumps are ones which have an open or semi-open impeller that allows clogs, rags or suspended particles to be pumped along with the fluid. A cutter is required before the impeller vane to shred the clogs, rags or other suspended particles.

Non-clog Pumps are used for a variety of applications such as Raw & unscreened Sewage, Industrial wastes & effluents, Municipal Sewer Lines, Tailing ponds, Sewage treatment plants, Effluent Treatment Plants, Pharmaceutical & textile units & many more similar applications.

Your submersible pump may not be working owing to various reasons. Please check the manufacturers troubleshooting guide, consult a trained mechanic or a customer service representative. The troubleshooting guide is available in Operation & Maintenance Manual.

The minimum level of submergence for a submersible pump depends on the type of service and the load the motor is subjected to. For continuous service, the pump must be completely submerged in the pumped fluid; for intermittent service, the pump also works when partially submerged (up to its minimum submergence level) but it must be allowed to rest for reasonable periods to prevent the motor from overheating.
Some of our models are fitted with a special cooling casing so they can operate continuously even when partially immersed.

During operation, a pump motor can face overload. Knowing the most frequent causes of overload can help prevent malfunctions. The main reasons for overload can be: the impeller is blocked by foreign particles, the mechanical parts block due to excessive stopping times, the density of the liquid is greater than the maximum permitted density etc.. If you have any doubts, contact your dealer or specialized Darling Pump maintenance technician.
