Hot Water Pumps

Hot water pumping is very common across various industries& it’s pumping is still a big challenge for many organizations. As there were major challenges in providing cooling for motor traditionally submersible pumps were not used nor recommended for pumping hot water. Worry no more, Darling pumps over the years has been pioneers in providing submersible pumps for Hot temperatures liquids. Our pumps are running successfully in variety of application in arena of Hot water pumping, catering to liquid temperatures up to 90°C.

Hot Water Pumps
Features
Impeller – Special corrossion / errossion resistant impellers to suit specifc applications. Impeller to suit Solids passage up to 100mm.
Motor – Highly efficient dry motor with built -in protection against temperature rise. Motor capable to withstand wide voltage fluctuations.
Shaft – Extra heavy duty SS Shaft.
Mechanical Seals – Specially designed Dual Mechanical seals with unique rubber material are fitted in independent seal chambers. Design is such that Seals are not exposed to pumpage liquid and are also independent of discharge pressure.
Bearing– Heavy duty ball bearing used at top and bottom ends to balance adverse load.
Cable Sealing – Special leak proof cable sealing arrangement,to avoid ingress of water through cable.no need to open motor for changing cable.

Hot Water Pumps

Yes, Submersible pump option can save space, offer portability & can be safer than the conventional pumps. These days, Submersible pumps are used very often for pumping hot water.

Not always, apart from change in MOC, there are few other critical factors which need to be considered while selecting a hot water pump.

At 100°C temperature water starts evaporating. It’s more like a steam, so generally pumps are recommended for water temperature up to 90°C temperature.

Normal pump cable or rubber parts may not stand good in hot water. There are specialized cable & rubber parts which are recommended for hot temperature liquids.

Yes, Hot water pumps are successfully being offered for Clear water, Dirty water, Slurries, Sludge & Effluents.
