[tab]C.R.I.’s Electronic Pressure Controller is yet another quality and reliable product from the house of CRI. It is carefully designed to regulate the water pressure in the domestic water supply system.  It switches ON the pump automatically whenever there is a pressure drop in the pipeline and maintains preset level of pressure in the pipe line.  The preset pressure level drops as and when the water is drawn. It also switches OFF the pump automatically once the pipeline is closed completely and, thereby, makes the entire pumping system effective and efficient. The built-in check valve and logic circuit system protects the pump from water back flow and dry running, which enhances the life-span of the pump.
Certain models of vertical type pressure controls have built-in adjustable pressure gauges wherein the pressure can be set manually based on the requirement[/tab]

[tab]CRI pipes are specially designed for submersible pumps, capable of handling both internal hydrostatic pressure as well as high tensile load caused by the pump weight and column water pressure and weight. In general, the first pipe fitted with the pump will be subjected to high hydrostatic pressure and the top-most one has to withstand the entire weight of the column water and pump.
The unique formulation used to in the manufacture of these pipes ensures that threads do not turn brittle , break or chip during the entire life cycle. the threading & dimension standards maintained make these pipes ideally suoitable for using as column pipes for submersible pumps worldwide.These pipes are produced in different types, which can be selected according to the installation requirements.[/tab]
