Hypro Roller Pump series 4000 includes 4101C, 4101N, and 4101XL.
Please note: For a few years Hypro used an "-A" on the end of the model number interchangeably with the above models numbers. For instance, a 4101C-A and a 4101C are the same pump.
4101 Series: maximum flow of 7.2 gpm, 2600 rpm. Standard rotation on the 4000 Series Roller Pumps is clockwise for coupling directly to a gasoline engine.
If you are only pumping water, the cast iron "C" version is recommended. The "C" version can also be used for agricultural chemical spraying, but you may also want to switch to the Ni-Resist or SilverCast 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.

In all machines with moving parts, some frictional wear is inevitable. The high-quality pumps manufactured by Hypro are no exception, 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.
