Diaphragm Pump Maintenance: Looking Beyond the Pump.

Posted by Dan Rose on Wed, Jun 22, 2011

Diaphragm Pump Rebuild?

How long should a Diaphragm Pump last before needing a rebuild kit?  The quick answer is a full season.  Keep in mind that the time frame may vary depending on the amount of time it's used and the type of chemicals that are sprayed.

Beyond the Pump

If your pump needs to be rebuilt every 3 months, you may have an intake restriction issue. To illustrate what an intake restriction will do to your pump, try drinking though a coffee straw at the same rate as you would a regular soda straw.  The feeling you get in your head as your tongue gets vacuumed to the roof of your mouth is the same stress your pump endures when the intake line is restricted.  If you continue to drink though the small coffee straw at a consistent rate, eventually you will develop a headache or maybe even pass out.  Either way, you will STOP.  Your Diaphragm pump will do the same thing; it is going to stop sucking (no pun intended).

Follow this checklist to make sure your Diaphragm Pump stays in good working condition:

  1. Check the strainer to make sure they are clear and the holes are not plugged
  2. Check the size of the strainer mesh if you have a high flow pump. Over 7GPM, mesh size should be 20-30
  3. Check the intake hose diameter 
  4. Make sure that the bottom of your tank is free from chemical build up and debris
  5. If you have a homemade jalopy pump with a long intake line, make sure there are no kinks in the line

If you need a rebuild kit for a Hypro, Kappa or any other pump you can find them on the right side bar of the pump you select on our website.  Or you can go to our home page  to view our complete product line.
