Tormac centrifugal openwell pump’s volute chamber and impellers are carefully designed to give the best possible hydraulic efficiency and suction lift characteristic. State of the art machinery, technology and expertise gained over the years are employed in the manufacture of these pumps using quality raw material, journal bushes and dynamically balanced rotating components to ensure long life. Tormac openwell submersible prime movers are squirrel cage water filled and water-cooled rewindable type made of a special waterproof pure electrolytic copper insulated with synthetic film material. A uniquely designed thrust bearings with high thrust capacity and good quality shaft seals are used to enhance the strength and durability. All single-phase motors are incorporated with thermal overload protector. All Tormac openwell submersible pumps are produced in accordance with ISO 9001 standards.
Tormac’s swimming pool pumps are developed with the combination of immense experience, cutting edge technology and integrated quality control system complying with internationally accepted standards. Tormac’s “ TSW” series swimming pool pumps are self-priming type inbuilt with pre filter basket for cleaning the pool water. The mechanical seals are made of graphite and alumina with close tolerance for perfect sealing systems and the dynamically balanced rotary parts ensure vibration and noise free operation. All the parts of both pumps and motors are made of high quality materials to enhance the life span and efficiency. All single phase pumps are equipped with thermal protector to protect the motor from adverse operating conditions.
“Tormac Water Circulatory pumps are used to circulate hot / cold water with adequate pressure in HVAC systems. All parts & components have been uncompromisingly tested to ensure trouble free performance and safety operation. The motor is of 2 pole asynchronous and squirrel cage type and consists of canned rotor portion. All the rotating parts are in touch with pumped liquid and thus it acts as lubricant to rotor, shaft & thrust bearings. An air vent plug is provided in the rear-end. The centrifugal impeller is of radial & closed type with corrosion resistant curved blades. Impeller, shaft with rotor, thrust bearing pad and the intermediate rings are assembled as a single unit to avoid the misalignment of the bearings. The thrust bearing is designed to withstand high axial thrust load. The particular model of pumps are equipped with a rotary switch in the terminal box that can be used to control the speed in 3 different levels based on the requirement. For trouble free operation the temperature of the pumped liquid should not exceed the specified level, the minimum inlet pressure should be maintained (to avoid cavitations) and dry run must totally be avoided. As the motor is impedance protected and consequently short-circuit proof, no additional motor protection is required. The pump is provided with standard length of cable lead out with plug. These circulatory pumps are generally used in tandem with heating systems. “
