Why Choose Darling Pumps? Critical areas in any submersible motor pump design are unquestionably its Winding, Sealing and Bearings. These three parts are like a heart for any submersible pumps & are very much interdependent on each other. So it is utmost important that the Special attention is given to these aspects while designing a submersible pump set. •
Darling Engineers don't think so! We don't keep our motors empty or so called “Air filled” under water. We fill them with oil even at the cost of inserting extra iron and copper for the pump motor. The use of the oil filled concept for DARLING motors together with PVC Insulated wire not only gives tremendous advantage in terms of quality but also has loads of beneficial side effects like the ones mentioned here.
•
Better Sealing Darling pump not only use the better seals, but the design is such that the importance of mechanical seal is negated to certain extent & makes sure that even if seal fails, the motor winding is not harmed, as compared to other makes, wherein the pump gets completely burnt but out and it has to be rewound.
•
PVC insulated winding Darling pumps are wound with Special PVC coated (WATER PROOF) Submersible Winding wire instead of Copper Enameled winding wires which are NOT WATER PROOF.
•
Better heat transfer Oil filled motor designs ensures better heat transfer & helps pump run cooler even when operated continuously, thereby offering long and reliable service in return.
