Safeguarding Pump Minimum Flow

The Model 730 relieves over pressure caused by excessive pump discharge during low demand. To keep a constant discharge pressure, the difference between pumped flow and consumer demand can be circulated back to pump suction.

Circulation valves are often exposed to severe cavitation because valve P and velocity are usually high while downstream pressure is very low. On the other hand, the valves operate under these conditions for relatively short periods. Increased valve durability for applications requiring long operating periods will be achieved by using cavitation resistant materials, adding a downstream orifice, installing an upstream pressure reducing valve, increasing valve size, or any combination of these choices.

The Pressure Flow Control Metering Device (PFCMD) from Bermad, integrates a vertical turbine Woltman-Type water meter with a diaphragm actuated hydraulic control valve equipped with one, two or more pilots. The PFCMD automatically performs one, two or more independent functions, such as sustaining a preset minimal upstream pressure, maintaining the level in elevated reservoirs or sustaining maximum set flow. All functions are performed irrespective of change in upstream pressure and / or demand. Functions can easily be added or removed in a modular way. The meter accuracy is independent and not affected by the action of the valve. An adjusting screw on each pilot allows setting of the desired set-point for Pressure, Level & Flow. The valve is compatible with SCADA.

Total command area is of 6978 hectares and it is divided into 57 zones of approximately 100 to 150 hectares and each zone is further divided into 16 sub-sections.After detailed designing Saisanket was able to optimize the cost of Distribution Network with the use of Air Management System, Outlet Management System, Electric Energy less and Wireless Automation etc and enable client to use these system for better efficiency, Project can operate as per the variable schedule depends on varying crop water requirement , rainfall, Maintenance, No Water Requirement.Remote Metering, Controlling, monitoring & synchronization of 912 nos Outlets Chaks (Discharge at every outlet is from 50 lps to 110 lps) with zonal pumping stations , intake & 2nd stage pumping station.
