C.R.I. Pumps (Pvt) Limited products

ECW series are single stage, end suction, back pull out, top centreline discharge type. These are offered with different material of construction to handle clear and slight raw water. Dynamically balanced impeller ensures vibration and noise free operation for long life. Mounting and duties are in accordance with EN 733 with DIN flanges suitable for continuous operation.

Single stage chemical process pumps are mainly used to handle different type of chemicals with slight impurities. These pumps are offered with different material of construction according to the liquid type. Dynamically balanced impeller ensures vibration and noise free operation for long life. Mounting and duties are in accordance with ANSI B73.1 suitable for continuous operation. To maintain impeller clearance external adjustment provision is provided to maintain required efficiency.

Hot water circulatory pumps are generally used to handle hot water with adequate pressure in domestic and other industrial applications. The motor is of two pole asynchronous type with canned rotor portion. All the rotating parts are in contact with pumped liquid and thus it acts as lubricant to motor, shaft and thrust bearings. And air vent plug is provided in the rear end for venting. Compact and rigid design provides reliable service for continuous operation and composite impeller provided for longer life. The rotary switch provided in the terminal can be turned to three different position to adjust the speed based on requirement.

Close coupled single stage, end suction centrifugal pumps in which the pump shaft will be directly coupled with standard induction motor by means of stub or split coupling. Close coupled design provides space savings and compact construction. It requires less space. A permanent rigid alignment in these pumps are done to eliminate the need for all other alignments. This in turn, prolongs seal and bearing life. Close coupled pumps are offered with standard and premium efficiency motors.

Close coupled, Single stage, top pull out vertical inline pumps are compact and rigid design. Top pull out design facilitates dismantling of motor, motor bracket and impeller without disturbing the casing and pipe work. The inline construction simplifies the piping work and major saving on floor space compare to the other type of pumps. Close coupled pumps are offered with standard and premium efficiency motors.

Medium consistency pulp and process pumps are used to handle different type of syrup, molasses, pulp, paper stock, raw water etc and it can be used maximum consistencies upto 8%. Dynamically balanced semi open impeller ensures vibration and noice free operation for long life and replaceable wear plate used to maintain optimum clearance between impeller and wear plate. To maintain impeller clearance external adjustment provision is provided to maintain required efficiency.

Horizontal Split Case single stage double suction centrifugal pumps are designed to deliver higher rate of flow at designed operating head. Double suction impeller with between bearing design provides hydraulic balance, hence eliminating axial thrust. The casing is split axially with opposing suction and discharge flanges greatly simplifying maintenance. The inline suction and discharge nozzles are cast in the lower half casing. This design makes it easy to remove the upper casing and rotary components without disturbing the motor and pipe work.

C.R.I “MV series” vertical inline pumps are multistage type supplied with radial and mixed flow impellers for higher head and flow requirement. These pumps are available in different materials of construction and all wetted parts are made up of corrosive resistant stainless steel material. The inline design simplifies the piping work and results in space saving compared to horizontal pumps. These pumps are ideally suitable for high and constant pressure applications. Inline pumps are offered with standard and high efficiency IEC / NEMA motors and DIN / ANSI flanges.

C.R.I “MH series” horizontal multistage pumps are end suction and top discharge type supplied with radial flow impeller for higher head requirement. These pumps are centrifugal monoblock type available in both single phase and three phase supply. Most of the wetted parts in the pumps are made up of corrosive resistant stainless steel material for durability. All single phase pumps are thermally protected.

Vertical turbine pumps are single stage or multistage in construction and submerged impellers allow the pump to be started without need of priming. VT pumps are designed to operate without being affected by large fluctuations of the water level. These pumps are supplied with mixed flow or axial flow impeller for higher flow requirement. The transmission shaft in the column pipes are supported with line shaft bearing with self or external cooling arrangement. These pumps can be either installed in wet or dry pit application. Ratchet arrangement provided on coupling to avoid reverse rotation.
