Your cart is empty.The Shurflo 5059-1310-D011 Automatic Demand 12V DC Diaphragm Pump features a built-in pressure switch that reacts to outlet pressure and interrupts power at a preset shutoff pressure indicated on the pump label. As soon as outlet pressure drops below a predetermined limit, usually 15-20 PSI less than the shutoff pressure, the switch closes and the pump will only operate until the shutoff pressure is achieved. This built-in pressure switch protects the pump in the event of dead-heading.

These are quality pumps but as with any product there are issues from time to time. My first pump arrived and did not run at all. I checked it with a meter and basically it was an open circuit. I ask to return the first and ordered a second pump and received the second pump today and installed on spray rig and it worked immediately, no problem. Sprayer is used for weed control around buildings and fences around the farm.

This was the exact replacement my husband wanted for our old broken Shurflo pump in our boat. The new replacement pump works perfectly, good quality and easily replaced our old one.

Item delivered on 1/10 and stopped working right after the 30 day return window had closed. Like a few other reviews state it stops working, unfortunately for us it was after the return window.

I gave this pump a 4 out of 5 stars for 2 reasons.1. At almost full pressure and low flow its designed to pulse the motor on/off at a high rate to slow the pump down, as apposed to lowering the actual RPMs. As a result it the start inrush current is high and it makes my lights flicker kind of like a strobe light. Annoying. The lights arent even on the same circuit. But same battery source. My fix was to add big capacitor inline with the pumps power feed within 8" of the pump. That fixed the problem. But I shouldn't of had to spend $45 to do that. 2. Somewhat noisey. I can hear it thru out my 48' boat. Installed in the far aft. Hi rate of pulsing probably doesn't help the noise level. Other then that... love it! Seems well built.

Everything, order time of shipment, delivery and installation was fine But the pump only worked for two weeks. The pressure switch would not stop the pump; actually the switch would tell the pump to quit and it would, but it immediately came on again so it wouls cycle continuously. This could not be adjusted using the adjustment screw, but it was accepted for return and purchase cost was refunded

Pump motor went out on a 60 gallon sprayer and glad I found this one too replace it. Just need to remember to clean it out at the end of using it so the weed killer doesn't mess it up again.
