This Hypro 1502C 6-roller pump features a cast iron housing and rotor and is equipped with Buna-N shaft seals and Super Rollers. The shaft rotation for this 30lb., positive displacement pump is counterclockwise. **Notes: It is recommended to use the 8460 model regulator for this Hypro 1502 series roller pump. Also, it is recommended to purchase a repair kit for this pump at the same time you purchase the pump so it is handy just in case your pump experiences frictional wear because in all machines with moving parts, some frictional wear is unavoidable.
