                                     PART I

ITEM 1. BUSINESS.

     IDEX Corporation ("IDEX" or the "Company") manufactures an extensive array
of proprietary, engineered industrial products sold to customers in a variety of
industries around the world. The Company believes that each of its principal
business units holds the number-one or number-two market share position in each
unit's niche market. IDEX believes that its consistent financial performance has
been attributable to the manufacture of quality proprietary products designed
and engineered by the Company, coupled with its ability to identify and
successfully integrate strategic acquisitions. IDEX consists of three reportable
business segments: Pump Products Group, Dispensing Equipment Group, and Other
Engineered Products Group.

PUMP PRODUCTS GROUP

     The Pump Products Group designs, produces and distributes a wide variety of
industrial pumps, compressors, flow meters and related controls for the movement
of liquids, air and gases. The devices and equipment produced by this Group are
used by a large and diverse set of industries, including chemical processing,
machinery, water treatment, medical equipment, Liquid Petroleum distribution,
oil and refining, and food and drug processing. In 2001, the six business units
that comprised this group were Gast Manufacturing, Liquid Controls, Micropump,
Pulsafeeder, Viking Pump, and Warren Rupp. The group accounted for 59% of sales
and 61% of operating income in 2001, with 37% of sales shipped to customers
outside the U.S.
