This is a quality gear pump that is simple and cost effective. The N4000 has a half and inch input and output and generally driven by the belts and pulleys of a Honda engine. Like all equipment use will eventually cause wear and tear. When your gear pump starts to leak simply tighten the packing nut an eighth of a circle turn, then back off a sixteenth. Generally speaking, you will get a year of work before that packing nut is turned all the way in and you must take apart the pump and replace with new packing. Widely used in the industry for its ease of use and highly effective. At Qspray.com you can find the gear pump and all replacement parts.
