Hot Water Circulatory Pumps


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.
