Pressure Tanks

[tabs slidertype="left tabs"] [tabcontainer] [tabtext]Description[/tabtext] [tabtext]Specifications[/tabtext] [tabtext]Features[/tabtext] [tabtext]MOC[/tabtext] [tabtext]Applications[/tabtext]  [/tabcontainer] [tabcontent]

[tab]The C.R.I. pressure tank is another reliable product from the house of CRI. Having 5 decades of expertise in the pump industry, these pressure tanks are ingeniously designed with perfection to deliver optimal performance. The butyl/natural rubber membrane provided in all the models ensures finer and trouble free performance. These tanks are used for pressure boosting applications to fetch self-sustained supply of pressurized water in the pipeline evermore especially in houses, apartments & hotels.
Pressure tanks eliminate the need of overhead tanks and float switches. The electro-mechanical switch automatically switches the pump ON and OFF whenever pressure reaches the minimum and maximum level of preset pressure. The smaller capacity tanks are vertical in shape, which can be fixed directly to the outlet of the pump, whereas bigger capacity tanks are horizontal/vertical in shape with legs and the pumps can be fitted over the platform provided on the top. A 5-way connector, electro-mechanical switch, hose connector and pressure gauge are the common accessories used along with the pressure tanks. The pressure can be preset. The pressure will be developed in the membrane based on the maximum operating head (in bars) of the pump.[/tab]

Electronic Pressure Control

[tabs slidertype="left tabs"] [tabcontainer] [tabtext]Description[/tabtext] [tabtext]Specifications[/tabtext] [tabtext]Features[/tabtext]  [tabtext]Applications[/tabtext]  [/tabcontainer] [tabcontent]

[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]
