Submersible Motor Eco Series
Description
Tormac Esteem series submersible motors are ingeniously designed and developed employing latest engineering softwares, high-tech machinery & tools with the complement of cutting edge technology for hardwearing and maintenance free operations and to ensure relentless performance.
The electrical conditions such as voltage, frequency and the operating conditions are taken into account in designing the winding and cooling system. Tried and trusted indigenously improved design, combined with the most optimized efficiency in electromagnetic design exceptionally ensures trouble free performance. The integrated and most modern quality assurance systems used at every stage of production and flawless workmanship lead to sustained and consistent operation.
Tormac Esteem series motors are non rewindable type. The stator is wound with high quality enameled copper wire and the stator shell is filled diligently with epoxy resin. Allowing faster and greater dissipation the resin ensures longer motor life. The stator shell, housings shell & motor base are made of fabricated S.S 304/316 which prevents the motor from corrosion.
These motors are pre-filled with environmentally safe deionised water mixed with propylene glycol which acts as a lubricant & coolant. A uniquely designed thrust bearing with high thrust capacity and good quality shaft seals are used to enhance the strength & durability. All single phase motors are supplied with suitable control boxes. All Tormac motors are produced in accordance with ISO 9001 standards and mounting dimensions with NEMA standard.
