Your cart is empty.This Square D Pumptrol 9013FSG2J21M4 electromechanical pressure switch with 30-50 psi pressure setting range activates an electrically driven water pump within a power circuit when the adjustable rising and falling thresholds are reached. The NEMA 1 enclosure has a 1/4" NPSF internal fluid connection and screw clamp terminals. The switch works with a 1.5 hp or less pump. The adjustable differential range is 15-30 psi and the cut-out range is 20-65 psi. The low-pressure cut-off (auto-start-off) operates at approximately 10 psig below the cut-in and will turn off the pump. The enclosure is National Electrical Manufacturers Association (NEMA) Type 1 and Ingress Protection (IP) 20 rated. The switch is Underwriters Laboratory (UL) Listed and Canadian Standards Association (CSA) Certified. Square D Pumptrol pressure switches are manufactured by Schneider Electric.

Easy To install and adjust. It is also made by the same Co. that makes "Square D" but for a lesser price.

This was easy to install following the instructions included. Have the switch on the unit make turning my well on and off easy.

Great quality, very reasonably priced, and easy to adjust PSI range. The added Low-pressure cut-off feature will prevent our shallow well 3/4hp Jet Pump from future over heating—popping off and warping PVC fittings & pipes on the intake and discharge ports, and ruining the pumps impeller & diffuser when the water pressure drops too low….Cheers! woody, Guam Island

When I opened the box, the Pressure Switch was missing the plastic cover. Since I need a water supply NOW, I will not be returning this for replacement. Instead, I will modify the cover from an old, non- working switch.

We have a toilet that sometimes runs and will shut off our water. This switch has saved us tons of money in pumps and well service! We had professionally installed but not too hard to use. If wire bar is sticking on just hold until powered back up. And put your cap back on!

This is a great pressure switch. If you are in well water like we are, you know how expensive a good quality water pump can be. If there's a loss of water pressure due to a leak, burst pipe, cavitation or the well goes dry, it can have a nasty effect on your pump. As the pressure drops, the pump gets hotter, even to the point of permanently damaging the internal components like the impeller and seals. This pressure switch has a low-pressure cut-off that will shut the pump off after a set differential pressure. It can save your pump from total failure and/or the headache of replacing your pump and piping or having to call a plumber. It's simple to install and adjust, but it does require a bit of knowledge of electrical safety. It costs a little more than a standard pressure switch, but it's worth it. I recommend it.Just wanted to add a little bit of info about pressure switch adjustments. There are two adjustments nuts that can be turned to adjust the switch. The larger adjustment spring is for adjusting the pressure range, e.g., this pressure switch has a factory set “range” of 30-50 or 20 PSI differential pressure (50 – 30 = 20) …meaning it’ll start your pump at 30 PSI and shuts it off at 50 PSI. Now, if you would want to increase the range to 40-60, you would tighten the nut on larger spring only approximately three full turns (one turn of the nut would be approximately between 2 to 3 PSI).Note that you don’t need to adjust the smaller spring tension to maintain the 20 PSI pressure differential, i.e., on the example above, adjusting the cut-off pressure to 60 PSI, will also cause the cut-in pressure to increase to 40 PSI, maintaining the 20 PSI differential pressure (60 – 40 = 20 PSI).For the most part, you don’t need to adjust the tension of the smaller spring, and this adjustment only affects the cut-off pressure. It basically affects how long the pump will run at each cycle. For example, if you were to tighten the nut (on small spring) for approximately three turns, it would increase your cut off pressure to 30 – 60 and in turn your differential pressure will now be 30 PSI instead (60 – 30 = 30) …meaning your pump will run a longer cycle. If you were to turn this nut to release spring tension, it would decrease the differential pressure accordingly. For example, turning the nut counterclockwise approximately three full turns, would decrease the cut-off pressure approximately 10 PSI and your pressure switch will now be set to 30-40. So, in this case the differential pressure would be 10 PSI (40-30 = 10) …meaning your pump will run a shorter cycle and hence more often.

The low pressure cut off gives you some protection then the supply runs dry. I say some, as the the supply just starts to fail, unless there is some drain, you can be caught with a running pump between turn on and shut off ( 50 PSI) . The heat causes any plastic close to the pump to soften, lose strength and fail. Instructing users to pay attention and change tanks at first sign of bubbles in water will save you money and down time.
