Yeomans Chicago Corporation

Factory Tour

After 50 years in Melrose Park, in 1999 YCC moved into a new state-of-the art facility in Aurora, IL.

Our machine shop features cell type workstations that feature various machine types depending on the operations performed.

Submersible motor housing castings are being machined on one of our Mazak CNC lathes.

Partially completed motor housings are being staged for their next operation.

An impeller is being trimmed using a manually operated lathe. We trim our impellers down to fractional inches to meet the specific duty point.

Our stock room features 24' heavy duty racking that houses patterns, castings and machined parts. All raw castings are stored indoors.

High lift reach trucks are used to pick skids and bins.

Impellers and motor rotor/shaft assemblies are balanced using an overhung or cradle type balancing fixture. Impellers up to 2,500 lbs can be balanced in house.

This section of the machine shop shows some our our larger equipment that is used for motor housings, volutes, larger impellers and comminutor cylinders. New machines include an O-M Vertical Boring Mill, Mori Seiki Horizontal Machine Center and a Mazak Horizontal Machine Center.

Shown on the right side is our plant offices where Quality Control, Production and Scheduling and Inventory control is based. In the background is our motor assembly area and our balancing station that features a computer controlled Hines balancer.

A suction plate is being set up for machining on our new Vertical Boring Mill. The program is called up using the operator interface.

Our O-M VBM can handle medium to large parts in small and large runs.

Our Mazak Slant Turns are used to make both production runs and piecework shafts.

Our test floor features a 100,000+ gallon in-ground wet pit that can be used to feed three separate test stations: submersible pump area, dry pit test area and grade level test area.

Our closed 54" test loop is used to test pumps ranging from 36" to 54" discharge size. Two 10 Ton cranes are used to configure piping arrangements and to place pumps into position for testing.
