General Description
The Sotera 400B Series is a self‑priming, positive displacement double action diaphragm pump. It features flow rates up to 13 gallons per minute (13GPM)
and is engineered with polypropylene and stainless steel wetted parts, along with seals that are compatible with most agricultural and industrial chemicals
as well as lubricants (e.g. those found within power transmission). These wetted materials consist of a polypropylene body and valves, stainless steel
fasteners, Hastelloy®check valve springs, Buna‑N, EPDM and Fluorocarbon seals, along with Hytrel®and Santoprene®diaphragms.
Sotera utilizes a recognizable naming system where model numbers reference the diaphragm material. Models that begin with ‘SS’ (eg. SS415B) contain
Santoprene diaphragms, while models that begin with ‘FR’ (eg. FR410B) contain Hytrel diaphragms. Santoprene is designed for moving agriculture
chemicals while Hytrel is used with oils and lubricating fluids. We strongly recommend referring to the Sotera Chemical Resistance Guide found
at sotera.com to determine proper materials of construction for use with your application.
The 400B Series pump is not compatible with strong acids (pH of 3.4 or below), strong bases (pH above 12), non‑diluted flammable liquids with a flash
point below 100°F/38°C, or bleach (sodium hypochlorite).

| 400B SERIES ELECTRIC DIAPHRAGM PUMPS OWNER’S OPERATION MANUAL
The 400B pump series is not intended to be used to fuel any aircraft, on or off road vehicle, or marine vessel.
This pump is not suited for use with fluids for human consumption.
Any electrical wiring should be performed ONLY by a licensed electrician in compliance with all local, state, and national
electrical codes (NEC/ANISI/NFPA 30, 30A, and 70) as appropriate to the intended use of the pump.
Always ensure that the pump is properly grounded prior to use.
Improper installation or use of this pump can result in injury or death.
Threaded pipe joints and connections must be sealed with an appropriate sealant that is compatible with the fluid being
transfered to minimize the possibility of leaks. Leaks of any kind can be detrimental to the environment and cause injury
to operators if in contact with skin or eyes.
General Safety Information
• All suction hoses should be reinforced to prevent collapse by
system pressure
• If there is a possibility of solids or debris within the liquid, at
minimum, a 10 mesh screen (0.07") or less needs to be utilized
either at the end of the suction pipe or entry into the suction side
of the pump. Particles greater than 0.1" will adversely affect
pump performance
• All suction hoses or pipes must be 1" diameter. Large sizes may
be used as long as it terminates to a 1" diameter at the suction
inlet of the pump
• Placement of the suction pipe should terminate 2" from the bottom
to avoid particulate contamination unless a 10 mesh in‑line screen is
being used as noted
• Maximum suction lift capacity is 9 FT (2.7 M) for water at sea level at
70°F. Suction lift for each application will be dependent on the
Centipose (cP) of the individual fluid as affected by temperature
and elevation
Mechanical Installation
• IMPORTANT: Tanks and containers must be vented to prevent collapses
• Tighten all non‑metallic fittings to a snug fit to prevent leakage.
Damage could occur to the pump if these fittings are over tightened
• Do not use the pump as the structural support of the
piping system
• Be certain the system components are properly supported to prevent
stress on the pump parts. As a rule and unless specifically designed
into the pump, suction and discharge connections should be flexible
to avoid damaging the pump body. Ensure that any connection material
is compatible with the substance being transferred through the
pump itself
To maximize performance and longevity of your 400B Series pump, we recommend the following considerations:
The mechanical yoke assembly is under extreme pressure. Never disassemble under any reason.
Always secure before use by anchoring any holding tank or barrel to prevent tipping under any condition.
Do not use any additional check valves or foot valves without consulting with Sotera Technical Service. These valves will
restrict flow rate and possibly increase system pressure that will affect the transfer pump performance.
Installation Best Practices (Suction Side of Pump)

sotera.com | tuthill.com 6
| 400B SERIES ELECTRIC DIAPHRAGM PUMPS OWNER’S OPERATION MANUAL
• Tuthill strongly recommends grounding the pump and motor prior
to any usage
• Electrically bonding to a vehicle frame or utilizing a ground circuit
for stationary applications are preferred grounding methods. Always
consult with a licensed electrician for your application
• Inspect any and all power and grounding cables prior to each use.
Replace if the outer protective jacket has been removed to expose
any wires
• For 12V DC non‑explosion proof motors, the power cable terminates
with battery clamps that are either red (+) or black (‑); however a
ground wire is not included
• For 12V DC explosion‑proof motors, in general, neither a ground wire,
power cable, or battery clamps are provided. See pages 14‑15 for
specific included components
• DO NOT connect the ground wire to the negative post of the
DC power source
Electrical Installation
Never disconnect the power cable while pump is switched on. Always switch the pump off PRIOR to disconnecting the 12V DC
battery clamps or the 110V AC plug from the power source. Electrical sparks or short can occur if not disconnected properly.
Electrical wiring installation should ONLY be performed by a licensed electrician in compliance with all local, state, and
national electrical codes (NEC/ANISI/NFPA 30, 30A, and 70) as appropriate for the intended use of the pump.
Be certain the power switch is OFF prior to connecting the battery clamps/power cables to the power source to prevent
unexpected starting of the motor. Unexpected motor start can cause unintended discharge of fluid, creating
explosion/fire/chemical spill hazards.
DC Power
Various models of the 400B Series are direct current (DC) through either an explosion‑proof or non‑explosion proof motor
at either 12V DC or 24V DC power. These same models may or may not have supplied cables for connection to either
a positive or negative battery terminal. For 12V DC circuits, a 30 amp fuse (20 amp fuse on 24V DC motors) should
be installed on the battery cable to protect the electrical system in case of a short. This fuse should be placed on the
positive cable.

EARTH / CHASSIS
GROUND
• All discharge hoses should be a minimum of 1" diameter. Large sizes
may be used as long as it terminates to a 1" diameter at the discharge
outlet of the pump
• Hoses greater than 20'may be used, however, reduced outlet flow at
the end of the hose or nozzle should be expected. Flow is dependent on
the cP of the fluid as affected by temperature and elevation
• Always use hoses and accessories that are compatible to the
product being transferred. For hoses, as a general practice Tuthill
recommends EPDM for agricultural chemical and Nitrile or Buna‑N
for petroleum‑based oils and lubricants
Installation Best Practices (Discharge Side of Pump)
Utilizing the diagram above, proceed with the following connections:
1. Ground connection (green clamp or eyelet)
2. Negative connection (black clamp)
3. Power connection (red clamp)

AC Power
Voltage drop in wiring varies depending on the distance from the electrical source to the pump and the gauge of the wire
used. Tuthill recommends referring to national, international, or local electrical codes to ensure the wire is of the correct
size for your application. The following chart is to be used as a reference and is not a substitute to electrical codes:
All AC pumps will operate at the rated nameplate voltage.
AC power should be supplied to the pump from a dedicated circuit with a 15 amp circuit protection. No other equipment
should be powered by this circuit.
Wiring must be of sufficient size to carry the correct current for the pump.
Voltage drop will vary with distance to pump and size of wire. Refer to the National Electrical Code (NEC) or local codes
for voltage drop compensation to be sure you are using the correct size wire for your application. Undersized wires can
overheat and cause a fire.
Ensure proper grounding to avoid electrocution.
Models of 400B Series pumps with explosion‑proof motors are classified for Class 1, Division 1 locations. It is highly
recommended that any repairs be done by an authorized distributor to avoid voiding the warranty. It is important to
maintain the explosion‑proof integrity of the motor and system components.
Electrical wiring installation should be performed ONLY by a licensed electrician in compliance with local, state, and
national electrical codes (NEC/ANSI/NFPA 70, NFPA30, and NFPA 30A) as appropriate to the intended use of the pump.

Routine Maintenance Schedule
1. Always check oil level by the sight glass prior to any fluid transfer.
The ideal oil level should be at the mid line or halfway point of
both site glasses. Add SAE 30W oil as needed to maintain the
necessary level
2. Inspect all external Torx(r) head screws are tight. If any screws appear
to be loose, torque to 75 in‑lbs
3. Inspect all motor flange hex head bolts are tight. If any bolts appear
to be loose, torque to 50 in‑lbs
4. Either annually or after 500 hours of usage, drain the existing
SAE 30W weight oil through a site glass port and replace with
approximately 16 oz of the same oil
Regular maintenance is critical to maintaining performance and extending the life of your 400B Series pump.
• Always turn off the transfer pump and disconnect from a power source
prior to servicing
• Always flush the pump completely prior to any service or disassembly.
Tuthill recommends the use of water for flushing agricultural and
industrial chemicals. For petroleum‑based products such as oils and
lubricants, flushing with diesel fuel is acceptable
• DO NOT PRESSURIZE THE FLUSHING FLUID. Damage to the pump
will occur. Instead, submerge the suction tube or inlet adapter in the
flushing fluid, then operate the pump as normal for approximately
15‑30 seconds or until the flushing fluid returns to its initial color.
Allow the pump to air dry prior to any service
• DO NOT SUBMERGE THE ENTIRE PUMP OR ELECTRICAL MOTOR IN
THE FLUSHING FLUID, ONLY THE SUCTION TUBE OR INLET ADAPTER
• Do not allow chemicals, lubricants, or oils to remain in the internal
pump cavity for any extended period of time. Crystallization or a glum
could become present, adversely affecting pump performance
• Tuthill highly recommends flushing the pump after each use to avoid
‘dry out’ and contamination between fluid transfers
• The interior pump cavity is filled with SAE 30W oil by the factory
in order to lubricate the internal gear drive mechanism and yoke
assembly. Certain pump repairs will require the draining of this fluid.
If necessary, remove one of the site caps found on the exterior of the
pump body and drain the oil through this port. Replace with new SAE
30W oil after repairs are completed through the same port. Tuthill
recommends 16 oz of oil to be placed inside the cavity or until level is
halfway within the site glass
Best Operational Practices
Individual Pump Component Removal and Replacement (refer to exploded pump view, page 13)
Use care in removing the diaphragm and check valve assemblies to avoid damage to the pump body. DO NOT pry the
diaphragm/check valve assembly away from the pump body with sharp or metal tools. Scratching or otherwise damaging
the pump body may cause leaks.
Do not attempt to replace individual parts. Replace entire assembly when required (kit 400F6557).
DO NOT DISASSEMBLE EXTERNAL GEAR ASSEMBLY. The planetary gears and ring gear are marked for proper assembly
and must not be altered.
Never disassemble yoke assembly. This is under extreme pressure and injury could result.
