Type D and G
The Class 9036 Type D and G float switches are lever operated and designed for open tank applications. These switches are floor mounted, or they can be pedestal mounted using mounting plate
9049UMS1. They are available in NEMA Type 1, NEMA Type 4, or NEMA Type 7 and 9 enclosures.
The Class 9037 Type E switches are flange mounted. Float movement is transmitted through a quad ring seal. Each switch consists of a basic switch, float rod, and float. The switch can be configured in the field for contacts that open on liquid rise or close on liquid rise. These switches are used for top mounted or side mounted, closed tank applications.
Alternators are designed to provide motor alternation in the operation of two motors.
