INTRODUCTION
WAUKESHA INTEGRAL SPEED REDUCER
The Waukesha Integral Speed Reducer is built for extremely durable service. It creates an
in-line link between the drive motor and the pump. Three models (sizes) are available:
49
,
79
and
239.
The cast iron casing houses quality reduction gearing, presenting eight speed reduction ca-
pabilities using two standard motor RPM inputs on the 49 and 79 units, 10 speeds on the 239
unit. Speed ratios are changeable in the field.
All fittings, bushings, keys and fasteners are supplied to fit the Reducer to C-face motors with
frames from 145TC through 286TC.
The Waukesha ISR design will drive Waukesha Universal Pump Models as listed in SPECI-
FICATIONS and can be retrofitted to these models in the field.
