One Pump for Several Water Tanks: How It Works
Mohit Vekariaशेयर करना
One pump may fill several water tanks. Each tank has its own use. One gets low while another stays full. Someone then has to check the tanks and turn valves by hand.
A multi-tank water-level controller can handle this task. It checks which tank needs water. It opens the right valve and starts the pump when the source and motor checks allow it. A timer alone does not check tank levels.
Why one timer is not enough
The tanks may use water at different rates. Their pipes and heights may differ too. One fixed pump time cannot show that each tank got the water it needs.
Draw the source, pump, pipes and tanks. Give each tank its own sensor and valve. VUKAR uses a solenoid valve for each tank. This is a water valve opened by an electric signal.
How the tanks fill
When tank 2 gets low, valve 2 opens and the pump starts. If tank 1 also needs water, valve 1 opens too. Both tanks can fill at the same time.
When tank 1 is full, valve 1 closes. The pump keeps filling tank 2. When the last tank is full, the pump stops.
The system checks the source water with a float switch. It also has dry-run protection for too little water while the pump runs. After a water shortage, it waits a set time before a retry. The water and motor checks still apply.
Which VUKAR system fits?
VUKAR offers a wired multi-tank control system. It is set up for the tanks and pumps at the site. It includes level control and motor protection. Check the exact protection features in the system quote.
The number of tanks, valves and sensors affects the setup. A normal one-tank panel may not accept extra tank sensors. Ask for a system built for the full tank plan.
The multi-tank system can be made for single-phase or three-phase pumps. These are different types of power supply. Give the supplier the pump's motor details. Each pump needs the right starter and motor protection.
What to check before ordering
List the tanks and their low and full marks. Map each valve to its tank. Set the source check and retry delay. Ask what happens after a power cut. Check whether a manual mode is needed.
A full tank, broken sensor wire and stuck valve are different faults. Ask which faults the system can detect. Do not assume it can prove a valve is open just because it sent an open signal.
When a simpler control may be enough
If you rarely change valves, a person may be able to do the job. If tank checks and valve changes are a daily task, linked tank and valve control may help.
For one receiving tank, use the tank-filling or sump guide. Two pumps filling one tank need a different control plan. Use the two-pump guide for that task.
Test it before use
Test each tank on its own. Then test two tanks filling at once. Fill one tank and check that its valve shuts. Check that the other tank still fills. Test the final pump stop, low-source stop and timed retry too.
The aim is fewer trips to change valves by hand. You still need to check the pump, pipes and sensors. The control cannot create water or fix leaks.
