Multiple Pump Pressure Controller(MPPC) is designed for pump cascading
This controller is useful for controlling multiple pumps (3 pumps) connected parallel in water supply line and supplying pressurized water via pressure tanks. A pressure transducer is connected in water line which gives signal to the controller and accordingly pumps are gradually turned ON.
How the Controller Works (Pump Cascading)
This system is about automatically turning pumps ON and OFF one by one to maintain a stable water pressure in the line.
* Pressure Monitoring: The controller constantly checks the water pressure using a connected pressure transducer (a sensor).
* Automatic Start (Turn ON):
* If the water pressure drops below a set level (because people are using water), the controller automatically turns ON one pump.
* If the pressure keeps dropping (people are using more water), it will turn ON the second pump, and then the third pump, one by one, until the pressure is restored.
* Simple Rule: Lower the water pressure more are the pumps turned ON.
* Automatic Stop (Turn OFF):
* If the water pressure builds up above the set level (because people stop using water), the controller automatically turns OFF the pumps, one by one (gradually as the pressure builds up), to save energy.
* Simple Rule: Higher the water pressure fewer are the pumps turned ON.
Key Features
1. Programmable Control
* MPPC is a programmable micro-controller based unit. It’s like a small, smart computer. You can tell it exactly what pressure to start a pump at (Cut-In or Start Pressure) and what pressure to stop a pump at (Cut-Off or Stop Pressure).
* Customization: You can set these start/stop pressures individually for each of the three pumps.
2. Pump Swapping (Cycling)
* What it is: It has a special Pump Swapping function.
* Simple Explanation: It makes sure that all three pumps get used equally over time. For example, if Pump 1 was the “last pump” to run in one cycle, the controller will ensure a different pump (like Pump 2 or 3) is the first one to start in the next cycle.
* Benefit: This prevents one pump from wearing out faster than the others, extending the lifespan of your equipment.
3. Separate Bypass Switch
* What it is: A Separate Bypass Switch is given for each pump.
* Simple Explanation: This is a manual switch for each pump. If one of the pumps has a breakdown (needs repair) or you simply want to take it out of service for maintenance, you can use this switch to manually take that pump out of the system without stopping the others.
* Benefit: This allows the remaining pumps to keep running and supplying water while the faulty one is fixed.
4. Real-time Pressure & Pump-ON Display
* What it is: The panel has a “Real-time Pressure Display” and along with that which Pump is ON is also indicated.
* Simple Explanation: This is a digital screen that constantly shows you the current water pressure in the line. It also indicates which pump is ON (only Pump 1 or two pumps 1 & 2 or all three 1, 2 & 3). So you can see exactly what’s happening.
