Pump Matrix
Husky 1590 Aluminum and Stainless Steel Pumps, Series A
Your Model No. is marked on the pump’s serial plate. To determine the Model No. of your pump from the following
matrix, select the six digits which describe your pump, working from left to right. The first digit is always D,
designating Husky diaphragm pumps. The remaining five digits define the materials of construction. For example, a
pump with an aluminum air motor, aluminum fluid section, polypropylene seats, PTFE balls, and PTFE diaphragms
is Model No. D B 3 9 1 1. To order replacement parts, refer to the part lists on pages 25–24. The digits in the
matrix do not correspond to the ref. nos. in the parts drawing and lists.
