C.R.I. Regenerative monoset pump's volute chamber and impellers are designed to give the best possible hydraulic efficiency and suction lift characteristics. Sealing is by means of a bellows mechanical seal made of carbon and ceramic is fitted over the shaft, which is ground to close tolerance. These pumps are power-driven by a totally enclosed fan cooled A.C. induction two-Pole motor, suitable for continuous duty. Motor stator is made of low watt loss silicon steel laminations assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration free and noise free operations and increase the life of the bearings and seal.

Features

• Built-in with imported motor protector
• Intended for wide voltage fluctuations
• Powder coated stator body
• Sturdy and compact
• Double sealed ball bearing

These pumps are power-driven by a totally enclosed fan cooled A.C. induction two-pole and four pole motor, suitable for continuous duty. Motor stator is made of low watt loss silicon steel laminations assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration free and noise free operations and increase the life of the bearings and seal.

Features

• Fitted with imported motor protector in two pole motors
• Intended for wide voltage fluctuations
• Sturdy and compact
• Back pull out type in specific models.

C.R.I. 250 mm (10") Borewell Submersible pumpset is made with different materials of construction together with extremely tough hardwearing bushes which make this pumpset highly durable. This pumpset is supplied with stainless steel & LTB-2 impellers to give better performance and longer life. The optimal design of impellers and diffusers offers best possible hydraulic efficiency. This pumpset is powered by a water filled, rewindable submersible motor, which is suitable for continuous duty. The stator is wound with special waterproof synthetic film insulated copper winding wires and made up of low watt loss silicon steel laminations assembled under pressure and rigidly locked in stainless steel stator shell. Specially designed thrust bearings (SS AISI 420 with Graphite Carbon) are used to withstand axial and down thrust loads with minimum wear and tear. Dynamically balanced rotor gives vibration free and noise free operation, thereby increases efficiency and life cycle of the motor.

Features

• Pumps are designed to give more discharge
• Extremely hard wearing water lubricated bearings
• Designed for extensive voltage fluctuations
• Silver brazed rotor
• 6 motor and 8 pump combination on request

C.R.I. three core flat cables conform to IS: 694. High conductivity annealed and bunched flexible copper conductors are made from electrolytic bright copper twisted together and insulated with colour coded special grade waterproof flexible PVC compound.
The final protection of outer sheath is made from high grade flexible PVC / Rubber compound impervious to water, grease, oil etc, thereby it ensures long life and has good withstanding capacity to high voltage and current.
These cables are sequentially marked at one metre intervals for convenience. Available nominal size in square milli meters are - 1.5, 2.5, 4, 6, 10 & 16 (Packing 300, 500 & 1000 metres in wooden drums).

C.R.I. energy efficient frictionless Foot Valves and Reflux Valves are basically swing type Non Return Valves. Foot Valves are available in screwed type construction and Reflux Valves have threaded portions at both the ends. They are specially designed to give an unrestricted smooth flow of water and thus to reduce the frictional losses to a minimum. The C.R.I. frictionless Foot Valve has 'K' value less than 0.8 and 'K' value for Reflux Valves are less than 0.5. Thereby it reduces additional load on prime mover and also gives more discharge.Foot Valve is placed at the lower end of the suction pipe of a centrifugal end suction pumpset to retain water in the pumpset casing and suction pipe to keep the pumpsets always in priming condition. Reflux and Non Return Valves are fitted generally in the delivery pipeline to avoid water hammer, up thrust and backspin effects in the pumping system. These can also be used anywhere in the suction line of which the bottom end is entered into a bore pipe or tube well. The pressure withstanding capacity of Reflux Valve and Non Return Valve are 1 bar and 15 bar respectively

Features

• Suction path is almost straight to the pipe and hence frictional loss is very less.
• Natural rubber flap totally prevents water leakage
• Ruggedly built with graded cast Iron
• Compact design and easy to install
• Metal parts of Foot Valves are coated with bituminous paint to avoid rust formation
• It increases water discharge upto 20% and reduces energy consumption upto 10%
