Openwell Submersible Pumps - Css, Cvs, Csm, Cv & Cvh Series
Openwell Submersible Pumps - CSS, CVS, CSM, CV & CVH Series centrifugal pumps are ideally suitable for open wells or tanks where there is a wide fluctuation in water level. This works under water and it rests at the bottom of the well. Hence, suction and priming problems do not arise. There are two types of pumps, namely horizontal and vertical. Pump portion is of a single stage or multistage and are fitted with cast iron casing. The pump's volute chamber is designed to give the best possible hydraulic efficiency. Dynamically balanced impeller offers vibration-free operation with long life. Prime mover is a rewindable, watercooled motor. Specially designed water lubricated bearings are used to withstand axial thrust loads with minimum wear and tear. The stator is wound with special water-proof synthetic film insulated copper winding wires and made up of low watt loss steel laminations, assembled under pressure and rigidly locked in a stainless steel stator shell. Dynamically balanced rotor gives vibration free and noise free operation, thereby increasing the efficiency and life cycle of the motor. Motor sealing is made by means of grommets, O rings, oil seals and sand guard to avoid ingress of well water/sand into the motor. Pressure equalising rubber diaphragm is provided to guard the pressure and volume variation of water inside the motor. Motor must be filled with clear, cold, drinking water as detailed in the operator's manual. Three-phase motor requires an adequate motor protection control panel. It is used in applications such as agricultural, irrigation, domestic, farms, civil water supply, fountains, industrial & rural water supply, fire fighting, pressure boosting, ponds, gardens, and mining. The specifications include SS and carbon thrust bearings used in vertical, open well sub, and bronze impeller in specific models.
