Square D 9037HG38 Liquid Level Switch
The Square D 9037HG38 is a horizontal liquid-level switch designed for side mounting on tanks with a 2-1/2 in MNPT connection. It closes its contacts when the liquid rises, providing automatic level control for pumps or alarms in water, wastewater or compatible chemical tanks. The stainless-steel float and stem resist corrosion in demanding industrial environments.
NEMA 1 enclosure with 50 psi pressure rating
The switch fits directly into a 2-1/2 in tank opening and requires a horizontal mounting plane with enough clearance for the 7.13 in float travel. Its DPST-2NC contact form handles up to 475 V and motor loads of 2 hp at 120 V or 3 hp at 240 V single-phase, simplifying wiring by eliminating separate motor starters for smaller pumps. The 16.06 in overall length and 5.98 in height determine the external space needed.
Replaces worn mechanical float switches
Upgrading from an older unit with a corroded float or degraded contacts restores reliable close-on-rise action and extends service life in the -22 to 220 °F operating range. The jump is worth it when the existing switch can no longer hold the 50 psi tank pressure or when the contact rating falls below the 475 V maximum required by the control circuit.

Questions about this item
What pressure limit is reached first during continuous operation?
The switch is rated for a maximum of 50 psi, so sustained tank pressure above that value is the first hard limit.
How much heat does the unit generate when running all day?
The switch itself produces no measurable heat; it simply opens or closes contacts within its -22 to 220 °F operating range.
What existing fitting must the tank already have for this switch to install?
The tank needs a 2-1/2 in MNPT threaded opening to accept the switch stem.
