C.R.I. The pressure Booster system has a complete combo package for water pressure boosting and it is precisely designed for hassle-free performance. The booster pumps are designed in such a way that whenever pressure drops/attains to the desired level, the pump will start/stop automatically.

A booster pump is designed to operate at high pressure. It has an impeller insider that improves the water flow and pressure. The movement of water, entering through the inlet and passing out of the outlet is brought about by an impeller. A tank present helps to build the water pressure. The impeller is spun by an electric motor. A water booster pump provides the pressure required to move water from a storage tank.

• Ensures even pressure at all the water outlets
• Automatic ON & OFF of pump while opening & closing of taps
• In-Built thermal overload protector, protects motor from overload fault
• Lesser running cost than the conventional systems
• Factory tested system and supplied as a package

• Stainless steel impellers,shaft and stage casings (SS / 304/ SS 316)
• All single phase motors are fitted with thermal motors protector
• Strengthened cartridge seals
• Enhanced hydraulic efficiency
• Good compatibility and environment friendly
• Low noise level and low vibration level

• C.R.I. Vertical multistage pump maximize performance, demonstrates high degree of consistency and is economical
• Pumps with VFD lasts longer as they can adjust the work load to meet the system requirement
• Extremely quiet and low vibration when in operation. The smooth, automated start and stop, reduces water hammer
• It avoids water pollution caused by roof tanks
• It also serves as the best replacement for the traditional roof tank water supply way, which is a source of water pollution

End Suction Pumps are centrifugal pumps that are typically designed horizontally and as single-stage pumps. End Suction Pumps are cost-effective and reliable. They are widely used in applications such as HVAC, irrigation, and in applications including industries such as food, sugar, paper, chemical, cement, and construction.

ECW Back Pull-out End Suction Pumps are of the single-stage with back pull out type. The impellers are of enclosed sort and are balanced statically and dynamically. The casing has axial suction and top centerline delivery and smooth hydraulic passages ensure high efficiency. These pumps are easy-to-maintain, reliable, and long-lasting.

• High operating efficiency
• Motor is designed with higher cooling effect to ensure the life
• Easy to dismantle and repair
• Available in SS304, Cl and Noryl impellers
• Available with 3 metre and 10 metre cable length

• Good suction lifting characteristics
• Silent operation
• Specially designed for wide voltage operation

CRI’s Mini Pumps are designed to be reliable and long-lasting. CRI’s mini water pump comes with a wide range of features.

A mixture of water air is used to reach a state of the fully primed pump. A low-pressure zone at the center is created, when the impeller located inside the casing rotates. The pressure difference inside the casing and the outside air causes a suction effect that results in water moving up the suction pipe. The self-priming pump mixes the air with recirculating water, all the air in the suction pipe is displaced and the water is discharged.

C.R.I. Openwell Submersible Pumpset – Ryker Series:

Pumpsets are ideally suitable for open wells or tanks where a wide fluctuation of water level occur. This works under water and rest at the bottom of the well. Prime mover is rewindable, water-cooled motor.

Specially designed water lubricated bearings are used to withstand the axial thrust loads with minimum wear and tear. The stator is wound the special waterproof synthetic film insulated copper winding wires and made up of low watt loss silicon steel lamination assembled under pressure and rigidly locker.

Motor sealing is made by polymers, ‘O’ rings, oil seals and sand guard to avoid ingress of well water/salt into the motor. Pressure equalizing rubber diaphragm is provided to guard the motor from pressure and volume variation of water as detailed in our operator’s manual.

C.R.I. has introduced highly efficient and reliable sewage & drainage pumps in a comprehensive range. Besides expanding its product portfolio, C.R.I. is firmly committed to contributing a vital role in creating a more pleasant and affluent living condition worldwide, which is one among its ambitious goal. These pumps are available with different materials of construction and feature a multitude of applications in wastewater handling and treatment.

A submersible sewage pump from CRI offers features that support efficient waste handling. A sewage pump is a single-phase pump since power requirements are lower. Sewage pumps from CRI have impellers that are non-clog type and they allow solids up to 40mm diameter. They help in the free flow of solids. A cutter range is used in the design that handles fibrous solids effectively.

• Impellers are non-clog type which allows solids up to 40mm diameter
• Non clogging impellers ensures free flow of solids
• Cutter designs yields fine solids for non clogging operation

Smart Pumps can be used for household water applications, small gardens, civil applications and pressure boosting systems.

C.R.I. proudly introduces the new Intelligence Smart Mini Pump with complete solution of water pumping. i-SMART pumps are specially designed for efficient and trouble-free performance. The integrated system protects the pump from a dry run operation, overload fault, and sudden voltage variation. The pump controller unit is equipped with an inbuilt timer that helps run the pump in real-time and at scheduled times. This feature enhances the effective running of the pump and lowers power consumption. The digital LED display embedded in the Smart pump supports to set the time and helps to monitor the voltage and current values. Float switch senses the over head tank water level and runs the pump automatically.

As‌ ‌the‌ ‌name‌ ‌indicates,‌ ‌a‌ ‌submersible‌ ‌pump‌ ‌is‌ ‌designed‌ ‌to‌ ‌be‌ ‌submerged‌ ‌within‌ ‌the‌ ‌fluid‌ ‌being‌ ‌pumped.‌ ‌They‌ ‌are‌ ‌also‌ ‌known‌ ‌as‌ ‌Submersible‌ ‌water‌ ‌pumps‌ ‌or‌ ‌open‌ ‌well‌ ‌submersible‌ ‌pumps.‌ ‌They‌ ‌measure‌ ‌up‌ ‌against‌ ‌jet‌ ‌pumps‌ ‌as‌ ‌they‌ ‌are‌ ‌not‌ ‌subject‌ ‌to‌ ‌variations‌ ‌in‌ ‌elevation.‌ ‌They‌ ‌work‌ ‌underwater‌ ‌and‌ ‌rest‌ ‌at‌ ‌the‌ ‌bottom‌ ‌of‌ ‌the‌ ‌well.‌ ‌Submersible‌ ‌pumps‌ ‌use‌ ‌significantly‌ ‌less‌ ‌power,‌ ‌as‌ ‌the‌ ‌fluid‌ ‌they‌ ‌pump‌ ‌is‌ ‌pushed‌ ‌and‌ ‌not‌ ‌pulled.‌ ‌

The‌ ‌prime‌ ‌part‌ ‌of‌ ‌the‌ ‌pump,‌ ‌the‌ ‌motor‌ ‌is‌ ‌sealed‌ ‌with‌ ‌polymers,‌ ‌‘O’rings,‌ ‌oil‌ ‌seals,‌ ‌and‌ ‌sand‌ ‌to‌ ‌prevent‌ ‌ingress‌ ‌of‌ ‌well‌ ‌water‌ ‌or‌ ‌salt‌ ‌into‌ ‌the‌ ‌motor.‌ ‌This‌ ‌feature‌ ‌helps‌ ‌in‌ ‌extending‌ ‌the‌ ‌durability‌ ‌of‌ ‌the‌ ‌submersible‌ ‌pump.‌ ‌The‌ ‌motor‌ ‌is‌ ‌prefilled‌ ‌with‌ ‌a‌ ‌cooler‌ ‌which‌ ‌regulates‌ ‌the‌ ‌temperature‌ ‌of‌ ‌the‌ ‌pump.‌ ‌A‌ ‌rubber‌ ‌diaphragm‌ ‌acts‌ ‌as‌ ‌a‌ ‌pressure‌ ‌equalizer‌ ‌and‌ ‌guards‌ ‌the‌ ‌motor‌ ‌against‌ ‌pressure‌ ‌and‌ ‌volume‌ ‌variation.‌ ‌The‌ ‌three-phase‌ ‌motor‌ ‌gives‌ ‌additional‌ ‌protection‌ ‌to‌ ‌all‌ ‌the‌ ‌electrical‌ ‌components.‌ ‌

C.R.I‌ ‌Submersible‌ ‌pumps‌ ‌offer‌ ‌higher‌ ‌water‌ ‌pulling‌ ‌capacity,‌ function ‌at‌ ‌wide‌ ‌voltage‌ ‌fluctuations‌ ‌as‌ ‌well,‌ ‌and‌ ‌are‌ ‌easy‌ ‌to‌ ‌install‌ ‌and‌ ‌operate.‌ ‌
