In this post we'll feature a few questions that have recently been posted to our blog comment box. 

Q:  "My Shurflo ATV sprayer pump (pump model #8000-543-936) pulsates. What's wrong?" - Tom R.    

A: To prevent pulsing try holding down the trigger on the spray wand and adjust the small Allen    screw in the front center of the pump head until the pulsation subsides.     

Q: "I bought a used Fimco 55 gallon PTO sprayer. I have a John Deere 1025R tractor and want to use the sprayer to do broadleaf control, liquid fertilizer, and things like that. What roller pump should I use?" - Wes T.  

A: We recommend the Hypro 7560XL "Silver Series" Roller Pump. This pump has great flow and  pressure and is cast from a stainless alloy specially designed for pesticides and herbicides.

Q: "My rig is pulsing and has very low pressure. It will start spraying perfectly,but then go back down to low pressure. I tried cranking up the psi, but it didn't  work. I've been working with a very frustrating rig. Please help! There is no clog in  filter..my gun isn't the issue. I think motor is going out, but maybe you can help" - Joe M.

A: Intermittent performance indicates that you may have a bad pressure switch. This switch is located on the front of the pump and has two red wires attached to it. Replacements switches are available for most models. 

Q: "I'm starting up our Hypro D503 for the season. It will build up pressure to 400 psi but when I engage the nozzle, it drops below 200 psi or lower but returns to 400 psi once the nozzle is turned off. I've checked and tightened all the connections. Cleaned the strainer on the intake and it's good. Thoughts?" - Chris T.

A: A drop in pressure when engaging the trigger normally indicates an air leak on the suction side. We suggest making sure the suction strainer gasket is set properly to form a tight seal and the bowl is not cross threaded or over tightened. You may also try watching the intake line to see if any air bubbles appear when activating the gun.
