Electromechanical Pressure Switches,
Class 9013 Types F and G
Introduction
The Pumptrol Class 9013 Type F commercial pressure switches are UL Listed and CSA certified as
commercial control equipment. Type G pressure switches are UL Listed and CSA certified as
commercial / light industrial control equipment.
The Type FHG compressor pressure switch is used to control electrically driven air compressors. It is
diaphragm actuated, and its contacts open on rising pressure.
The Type FSG, FTG, FYG, and FRG water pump pressure switches are used to control electrically
driven water pumps. They are diaphragm actuated.
• The Type FSG standard water pump switch is suitable for all types of pumps, including jets,
submersible, and reciprocating.
• The Type FTG fixed differential water pump switch is suitable for all types of pumps, including jets,
submersible, and reciprocating. It is an ideal choice for OEM markets. Minimum quantity
restrictions apply.
• The Type FYG is designed to meet higher horsepower and pressure requirements.
• The Type FRG is reverse acting: the contacts open on falling pressure.
The Type G commercial / light industrial pressure switch is used to control electrically driven water
pumps and air compressors. It has higher electrical ratings for direct control of motors in pump and
compressor applications. The Type G switch is diaphragm actuated, and its contacts open on rising
pressure.
Setting Points
Every pressure switch has two setting points: one on rising pressure and one of falling pressure. For
pumps and compressors, the setting point on rising pressure is called the trip point or cut-out; the
setting point on falling pressure is called the reset point or cut-in.
Differential
The differential is the difference in pressure between the trip point (cut-out) and the reset point (cut-in).
It can be adjustable or fixed. Example—Cut-in (30 psi) / Cut-out (50 psi): Differential = 20 psi
Range
The range indicates the pressure limits within which the settings can be adjusted. The range is
referenced to the setting point on rising pressure (trip point). The differential subtracts from the trip
point setting. When using a diaphragm-actuated switch, system pressure during the normal operating
cycle should never exceed the upper limit of the range. Excessive pressure will greatly reduce the life
of the diaphragm.
Maximum Allowable Pressure
Maximum allowable pressure is the pressure to which a switch can be subjected without causing a
change in operating characteristics, shift in settings, or damage to the device. Pressure surges may
occur in a system during the start up of a machine or from valve operation. Surges are not normally
detrimental to the life of a switch if the surge is within the maximum allowable pressure rating of the
switch. Diaphragm-actuated switches should not be subjected to more than 10 surges per day. More
frequent surges will greatly reduce the life of the diaphragm.

Settings
Pressure switches with adjustable differential
(Types FSG, FYG, and FRG)
When setting the pressure switch, adjust the setting point on falling pressure
first, then the setting point on rising pressure (PB).
• Setting point on falling pressure
The setting point on falling pressure is set by adjusting range-nut
1
.
• Setting point on rising pressure
The setting point on rising pressure is set by adjusting range-nut
2
.
Pressure switches with fixed differential
(Types FTG and FHG)
Only the setting point on rising pressure is adjustable.
• Setting point on rising pressure
The setting point on rising pressure is set by adjusting range-nut
1
.
• Setting point on falling pressure
The setting point on falling pressure is not adjustable.
The difference between the tripping and resetting points of the contact is the
inherent differential of the switch (due to factors such as contact differential
and friction).
Pressure switches with adjustable differential
(Type G)
When setting the pressure switch, adjust the setting point on falling pressure
first, then the setting point on rising pressure.
• Setting point on falling pressure
The setting point on falling pressure is set by adjusting range-nut
1
.
• Setting point on rising pressure
The setting point on rising pressure is set by adjusting range-nut

Float Switches—Class 9036, 9037, and 9038
Introduction
Square D™ brand offers a wide range of electromechanical level control products.
• Class 9036, Open Tank
• Class 9037, Closed Tank
• Class 9038, Mechanical Alternators
Class 9036 Open Tank
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, Type 4, or Type 7 and 9 enclosures.
Type FG
The Class 9036 Type FG30 pedestal-style sump pump switch is designed for liquid level control with
electric-motor operated pumps, either directly or through a magnetic starter. It can also be used to
activate alarms in liquid level control systems. The upward or downward movement of the lever arm of
the float switch controls the On and Off positions corresponding to the water level changes required to
turn the pump or alarm on and off.
NOTE: The rod for this device is 33.75 in. long. It cannot be lengthened.

Class 9037 Closed Tank
Type E
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.
Type H
The Class 9037 Type H switches are attached to the tank by means of a 2-1/2 in. bushing. An external
pointer indicates the float position within the tank when the unit is mounted. Switches come complete
with stainless steel float and rod. A nitrile rubber seal, such as a Buna-N quad ring seal, is used
between the float rod and the sealing connector. Normal application is at atmospheric pressure. Where
higher pressures are encountered, the available Viton
®
seal allows the switch to withstand tank
pressures up to 50 psi at ambient temperatures up to 220 °F. Occasional replacement of the quad ring
seal may be necessary.
Class 9038 Mechanical Alternators
Type A (Open Tank)
The Class 9038 Type A Open Tank level switch is a mechanical alternator designed to provide motor
alternation in the operation of two motors.
Type C (Closed Tank, Bushing Mounted)
The Class 9038 Type C Closed Tank level switches are bushing mounted. Float movement is
transmitted through a quad ring seal. Each switch consists of a basic switch, rod, and float.
Type C switches are attached to the tank by means of a 2-1/2 in. bushing. An external pointer indicates
the float position within the tank when the unit is mounted. Switches come complete with bushing,
stainless steel float, and rod.
Occasional replacement of the quad ring may be necessary.
Type D (Closed Tank, Flange Mounted, Top)
Type D mechanical alternators are designed for applications where flange mounting is to be made at
the top of a closed tank.

Selecting a Float Switch
Standard float switches have two contacts that close when the liquid rises above the designated level.
This contact configuration is used for tank emptying applications. Float switches are also available with
reverse (Form R) and double throw (Form H) contacts. Form R switches, used for tank filling
applications, have two contacts that open when the liquid rises above the designated level. Form H
switches, which can be used for both applications, have one normally open (N.O.) and one normally
closed (N.C.) contact.
To select the proper Square D™ float switch, determine the following:
• Type and shape of tank (open, closed, sump, etc.)
• Enclosure requirements
— NEMA Type 1: For general purpose applications intended for indoor use.
— NEMA Type 4: For watertight and dusttight applications for either indoor or outdoor use.
— NEMA Type 7 and 9: For explosion proof applications. Suitable for Class I, Division 1 and 2,
Groups C and D and Class II, Division 1 and 2, Groups E, F, and G hazardous locations.
• Total level change required
• Mounting requirements (such as flange mounting or screw-in bushing)
• Horsepower, phase, and voltage requirements
• Float material
— Stainless steel (SS)
— Plastic (available on 9036FG30 and as a Form for use with diesel fuel)
• Rod material
—Brass
— Stainless steel (SS)
— Aluminum (Al)
In direct motor control applications, float switch ratings must be greater than or equal to the pump
motor ratings.
NOTE: Contact the Sensor Competency Center when using float switches in liquids with a specific
gravity different than water (1.0).
Specify the Class and Type when ordering float switches or accessory kits.
Selecting Floats and Rods
Class 9036 and Class 9038 Type A float switches are actuated with the Class 9049 Type A line of
accessories. Select the float and rod material according to the corrosiveness of the liquid used in the
application. Two types of float kits are offered:
• Tapped-at-top float (Class 9049 Type A6, A6S, and A6A)
• Center-hole float (Class 9049 Type A6C, A6CS, and A6CA)
The tapped-at-top float is for applications requiring short lengths of tubing and small liquid level
changes. The maximum tubing length is 12 ft (3.66 m). Adequate space must be available to allow for
ceiling clearance when the level changes. The float must be buoyant enough to lift the tubing, stop
collars, and switch lever. The rod has two stops, one above and one below the switch lever. The
position of the stops determines the amount of water level change.

The center-hole float is used in applications requiring long lengths of tubing and large liquid level
changes. A compensating spring, used for longer lengths of tubing, supports the weight of the tubing
and stops. When a compensating spring is used, the float must be buoyant enough to lift up the switch
lever and heavy enough to trip the switch lever down. The rod has four stops. The position of the stops
on the rod above and below the float determines the amount of water level change.

Class 9037 Type E Closed Tank Float Switches
Class 9037 closed tank float switches are used primarily on condensate pumps but may also be
installed on closed industrial and diesel fuel day tanks. There are two types of Class 9037 float
switches:
• Type E (flange mounted)
• Type H (with screw-in bushing)
Class 9037 Type E Flange-Mounted Float Switches
Table 15 contains ordering information for Class 9037 Type E float switches. Order the rod and float
accessory kits separately. Contact the Sensor Competency Center when using Class 9037 float
switches in liquids with a different specific gravity than water (1.0).
For rod kit catalog numbers, refer to pages 55 and 56.
To receive all components packaged in a single carton, specify:
• Float switch Class, Type, and Form
• “R” and the rod number
• “F” and the float number
For example, to receive one each of 9037EG8, 9049ER1, and 9049EF1, specify 9037EG8R1F1.

Class 9038 Type A Mechanical Alternators
Class 9038 mechanical alternators provide a simple, positive means of mechanically alternating two
pumps or motors. These alternators are used on devices that are installed in a duplex system with a
common tank. There are three types of Class 9038 mechanical alternators:
• Type A (open tank and sump)
• Type C (with bushing)
• Type D (flange mounted, vertical)
When liquid level rises to the first level, one pump turns on. Both pumps automatically turn on when a
peak condition occurs and the liquid level continues to rise. If Form N5 or N25 is present, and the water
level continues to rise, a high water alarm is activated.
Mechanical alternators can be ordered with a manual transfer selector switch (Form N3), which allows
the operator to select which pump cuts in first. The second pump only operates under peak demand
conditions or if the first pump fails. When the switch is disengaged, the alternator reverts to normal
operation. Another option (Form N4) allows the alternator to be used as a two-level non-alternating unit.
Class 9038 Type A Open and Sump Tank Mechanical Alternators
Table 21 contains ordering information for Class 9038 Type A mechanical alternators, including factory
installed modifications. Order float accessories separately. Contact the Sensor Competency Center
when using Class 9038 alternators in liquids with a different specific gravity than water (1.0).
When ordering a factory modification, add the Form number to the end of the mechanical alternator
catalog number. For example, to select a 9038AG1 alternator with reverse action, order 9038AG1R.

Table 22 lists the operating forces for Class 9038 Type A alternators. Use this table when selecting
additional tubing or when selecting floats and rods for accessories made by other manufacturers.
Accessory Kits
Table 23 lists the Class 9049 accessory kits for Class 9038 Type A alternators. The accessories are
ordered separately from the alternators. Order tapped-at-top floats for Type AG1 (except form C) and
center-hole floats for Types AG1C, AW1, and AR1.
When ordering float accessories, first specify the desired accessory kit, then as a second item, give the
catalog number and the quantity of the additional tubing kits required. For example, for a 9049A6C kit
with 15 ft of tubing, specify:
A. 9049A6C, quantity = 1 (includes 5 ft of tubing)
B. 9049T1, quantity = 4 (2.5 ft of tubing each, for a total of 10 additional ft)
