Gallon Jar Pump, 110 mm - Solution

Solution pumps come with (3) discharge fittings with varying opening sizes. Thick products work with the largest opening and thin the smallest. If your product is dripping, it may need the next smaller opening from what is installed. Too hard to push? Use the discharge fitting with a larger opening.

When this happens on a Solution pump, the first place to look is within the pump assembly. With the pump apart, check if the ball valves and seal are properly installed. Ball valves must be facing downward.

Our trick to remembering this is to say, in your mom's voice, "Put the BALL DOWN!". My bet is you won't forget it, no matter how hard you try.

If the plunger is not returning to start position after dispensing, it may likely be a broken spring. The spring is a replacement piece that will eventually wear out and break.

Sometimes how the pump is assembled can cause it to "lock-up" somewhat. During assembly, compress the pump and spring, while aligning flats on piston with the flats inside the cylinder. Another tip is the locking collar should be installed with the pump compressed.
