For use with water well pumps and booster pumps, the Cycle Stop Valve (CSV) turns any pump into a variable flow, constant pressure system. Working in conjunction with a small pressure tank, the CSV is usually adjusted to the middle of the pressure switch range. IE; 40/60 PSI switch, 50 PSI CSV. The size of the pressure tank determines how much water can be used by the house, before the pressure drops to 40 PSI, and the pressure switch starts the pump. As long as flow rates in and around the house vary from 1 GPM to as much as the pump can produce, the CSV maintains a constant 50 PSI on the system. When there is no more flow required for the house, the CSV allows the little pressure tank to fill to 60 PSI, and the pump is shut off by the pressure switch.
Mist, Drip, Spray, or Big Guns, the Cycle Stop Valve (CSV) turns any Submersible, Turbine, or Centrifugal pump into a variable flow, constant pressure system. The CSV maintains a constant pressure on the irrigation system throughout a wide range of flow. Eliminating line breaks and leaks, while precisely applying an exact amount of water, the CSV can conserve water as well as energy.
Operations like oil blending, additive mixing and filling of the finish lube oils are fully automatic batching processes, performed within parallel lines, each consisting of one blender and one weigh hopper. The process requires quality pumps – and around the world DESMI has been a reliable partner for many years as our ROTAN® GP and HD series are designed for giving an accurate and constant flow to support this process.
Our stainless steel pump, ROTAN® CD, is also frequently used when special additives demand a higher material standard to give the best possible life cycle cost solution.
Keeping the weight ratios of the lube oil components is ensured by their precise weighing and is program-controlled by remote opening and closing of dedicated valves. Basic feeds to the blending process are the base lube oil stocks.
Cities, Towns, Sub Divisions, Mobile Home Courts, High Rise Buildings, and many others can use the Cycle Stop Valve (CSV) to turn any Submersible, Turbine, or Centrifugal pump into a variable flow, constant pressure system. The CSV maintains a constant pressure on the water system throughout a wide range of flow. Eliminating line breaks and leaks, while precisely providing any amount of water required, the CSV can conserve water as well as energy.
Consider integrating a variable frequency drive. It often can optimize energy efficiency by enabling you to match motor speed to the demands of the system. Look for opportunities, for example, to replace throttle valves or dampers used to restrict flow. However, a variable frequency drive may not make sense if the load on the motor is relatively small and constant — because speed changes will occur infrequently and any benefits from varying the speed will be negligible. So, thoroughly assess the system load profile to determine the scale and frequency of required speed changes before deciding about installing a variable frequency drive.
