CRI In-line Pumps

In-line Pumps

C.R.I.’s vertical In-line centrifugal pumps (VS Series) are non self priming axial suction and delivery type with Standard motor and Shaft seals. All components like impeller, diffuser & shaft of these pumps are carefully designed to deliver the best possible hydraulic efficiency. The pumps are of the close-coupled type wherein the pump and motor are of separate units in bigger power ratings which ensure easy dismantling and service.

These pumps are powered by a totally enclosed fan cooled. A.C. induction motor, suitable for continuous Duty. Motor stator is made of low watt loss steel lamination assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration and noise free operation. Shaft of Ample size made of quality steel and precisely ground is used for transmitting rated Horse Power.

Technological competence and immense experience of C.R.I. pumps always inspire its Engineers in an optimistic manner to come out with successful and innovative products. These single head circulatory pumps are yet another quality products from the house of C.R.I. which can meet the demanding technological challenges, and stand as testimony to C.R.I.’s quality & consistent performance for years.

C.R.I. Circulatory pumps are used to circulate hot / cold water will 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.
