If you are only pumping water, the cast iron "C" version is recomended. The "C" version can also be used for agricultural chemical spraying, but you may also want to switch to the Ni-Resist or XL version for longer life. Pumping wettable powders through a roller pump will reduce the life of the rollers because of the friction on the rollers. If you are using wettable powder chemicals, Rittenhouse recommends using a diaphragm pump.
Rittenhouse stocks replacement parts and repair kits for these Hypro Roller pumps, see below.

In all machines with moving parts, some frictional wear is inevitable. This is no exception with the high-quality pumps manufactured by Hypro--especially under heavy use by professionals. Therefore, we recommend purchasing a repair kit for this pump at the same time you purchase the pump so that you have it on hand when (and if) you need it.
