How do you protect well pump from running dry?
There are several manufacturers of submersible pump protectors that can be installed by qualified water well contractors that will protect your pump from running dry. Figure 2. A fractional horsepower pump controller (left) and a run dry protection device (right) installed by a water well contractor.
What is a pump saver on a well pump?
Details. The Model 233-P single-phase Pump Saver Plus is a pump monitor designed to protect single-phase pumps from dry-well, dead-head, jammed impeller, rapid cycle and overvoltage and undervoltage conditions.
How does a pump saver work on a well?
A storage tank usually has a float switch that turns off the well pump when the storage tank is full. The well pump is turned on again when the water level in the storage tank drops a few inches, and the float switch drops. The well pump can be supplied with a flow restricting device such as a Dole valve.
How long can a water pump run dry?
If the pump is run dry for less than 45-60 seconds, the pump should not suffer damage. Anytime you are aware that the pump may have to be run dry to empty the tank, the operator must take care to ensure the pump is run dry for the absolute minimum amount of time.
What happens if water pump runs dry?
Dry running occurs when a pump operates without adequate liquid. This leads to a surge in pressure, flow or overheating that will instigate a pump failure. As a result, the pumping elements seize up on the shaft.
How do I calibrate my pump saver?
The PumpSaver®Plus can also be calibrated while the pump is running. Turn the RESTART DELAY/ CALIBRATION knob to CAL. while pumping. Wait for the pump to turn off (approximately 10 seconds), then adjust the RESTART DELAY/ CALIBRATION knob to the desired setting.
How do I reset my pump saver?
Why you shouldn’t run a pump dry?
Dry running your pump causes friction, and this friction is strong enough to heat up the impeller, causing it to melt. ² Even minor melting is severely detrimental to your pump’s performance, potentially causing it to seize up and stop working at all.
What happens if you run water pump dry?
Allowing the pump to Run-Dry For a mechanical seal pump, running dry could lead to pump cavitation and therefore seal damage. The mechanical seal could also experience thermal shock and under the right conditions could shatter within 30 seconds.
How long can a well pump run dry?
How does a well pump work on a dry well?
The well pump is then shut off on low amperage, the well recharges for the length of time adjusted on the dry well protection device, and the well pump is again restarted. This process is repeated until the storage tank is full, and the float switch shuts off power to the well pump.
Can I use a pump in a low yield well?
When using a pump in a low yield well, it is advisable to use some sort of dry well protection. A low pressure cut-off feature on the pressure switch will work most of the time. However, if the well was almost depleted just as the last faucet or tap is closed the well could be pumped dry while trying to refill the pressure tank.
How do dry well protection devices work?
Other Dry Well protection devices like the Cycle Sensor look for low amperage instead of low pressure. The amperage drawn by the motor is always lower when air is in the pump instead of water.
How many gpm should a dry well pump produce?
Dry Well Protection. If the well yield is only 1 or 3 GPM, then a 1 or 3 GPM Dole valve is used, and the storage tank is filled at 1 or 3 GPM. Most well pumps can safely produce as little as 1 GPM without overheating. It is still a good idea to use a low amperage dry well protection device for safety.
