Tormac cast iron submersible pumps are ingeniously designed and developed employing latest engineering softwares, high-tech machinery, tools and cutting edge of pumping technology to deliver the best possible hydraulic efficiency. The integrated and most modern quality assurance systems used at every stage of the production and flawless workmanship ensure sustained and consistent operation. All these submersible pumps are multistage single suction centrifugal type and provided with integral check-valve and NEMA standard coupling. These pumps are available with impellers made of bronze, diffusers made up of cast iron and the shaft is made of AISI 410/431. The integral check valve prevents back flow, up thrust and reduces the risk of water hammer which paves the way for trouble free performance. The suction screen is designed with utmost care so as not to reduce the inflow of water and at the same time to prevent damage to the pump and clogging due to the entry of sand and other foreign particles.
Tormac TH Horizontal Multistage Centrifugal pumps are specially designed to facilitate pressure boosting and are best suited for a wide range of applications. The vital components viz. impellers, diffusers, and shaft used in these pumps are made of corrosion resistance high quality Stainless Steel which ensure a smooth and trouble free performance helps to pump safe and hygienic drinking water system. The prime mover of this product is robust in construction and built with thermal overload protection (only in single phase motors). High quality mechanical seals are used to ensure less friction / power loss.
“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. “
Tormac End suction pumps with volute casing DIN 16 DIN 2532/2533 single stage end suction with bearing housing, Dimension in accordance with DIN 24255. End suction pumps are single stage centrifugal, non-self-priming, volute pumps. These pumps feature horizontal shaft components with axial suction and impellers and radial discharge ports. Pumps volute chamber and impellers are carefully designed to give the best possible and suction lift characteristics. Most modern and highly sophisticated machinery and technology are employed in the manufacture of these pumps using quality raw material, dynamically balanced impellers, seal and bearings to ensure long life.
