NXT Air-Powered Pumps
Your model number is marked on the pump identification plate located toward the rear of the air motor. To determine
the model number of your pump from the following matrix, select the six digits which describe your pump. The first
digit is always J for circulation pumps. The remaining five digits define the construction. For example, a circulation
pump with carbon steel construction, a 2.0:1 ratio, low noise exhaust, no communication option, npt fittings, and
chrome rod and cylinder is model number J C 20 L 1. To order replacement parts, see page 18.
