Diaphragm Service Kit Suits Udor Kappa 33 43 53 Pumps
DIAK601
This repair kit fits the following Udor Diaphragm Pumps: Udor Kappa 33, Kappa 43, and Kappa 53.
The diaphragms on your Udor pump should be replaced every 500 hours or at season's end, whichever comes first. If you see the pump oil has a milky grey color or if the oil plug pops out, in most cases this indicates one or more of the diaphragms have split. Stop running the pump and replace the diaphragms immediately. Using your diaphragm pump with torn diaphragms can cause extensive damage to the pump.
- Service kit includes piston diaphragms and valve seals.
