New Part # 6062.97 is the replacement diaphragm kit for the Udor Zeta-40/85 diaphragm pumps. This rebuild kit also works for the Zeta-40P/85P pumps. Udor recommends pumps to be rebuilt after 500 hours of use or at the season's end, whichever comes first.
The diaphragm kit includes three replacement Desmopan diaphragms and six replacement valve o-rings.
