WARNING
Death or serious personal injury might occur if proper
operating procedures are not followed. The pump operator, as well as individuals connecting supply or discharge hoses to the apparatus must be familiar with
these pump operating instructions as well as other
operating instructions and manuals for the apparatus,
water hydraulics and component limitation.
!
WARNING
Pressure Hazard. May result in personal injury.
Prior to connection or removal of hoses, caps or other
closures with pump intake or pump discharge connections, relieve pressure by opening drains or bleeder
valves. Bleeder valves should also be used while filling
a hose connected to an intake with water.
!
WARNING
Scalding Water Hazard. May result in serious
burns.
When operating the pump, be sure to open at least
one discharge valve slightly to prevent the pump from
overheating. If the pump runs for a few minutes completely closed, it may heat the water enough to scald
someone when the valve is opened. Overheating can
damage the packing, seals and other pump parts. If
the apparatus builder has installed a by-pass system
or other provision designed to prevent overheating,
opening a discharge valve may be unnecessary.

Safety Information
Read through the safety information and operating instructions before using your Fire Pump.
WARNING
Hose Testing Hazard. May result in serious personal injury.
Due to a potential for catastrophic hose failure during service testing of fire hose, it is vital that safety precautions be taken to
prevent exposure of anyone to this danger. Fire pumps on fire department apparatus are not designed for and should not be
used for service testing of fire hoses. Hose testing machines should be used for service testing of fire hoses.
WARNING
Pressure Hazard. May result in serious personal injury.
If a fire pump on a fire department apparatus is used for service testing of fire hoses, the procedures in NFPA 1962 MUST
be followed including the use of a fire department gate valve with a ¼-inch (6 mm) hole drilled through the gate installed
between the fire apparatus discharge outlet and the hose test layout to prevent a volume surge from the pump in the event a
hose bursts during testing.
WARNING
Scalding Water Hazard. May result in serious burns.
If a fire pump on a fire department apparatus is used for service testing of fire hoses, pump discharge water must be
circulated through a by-pass system or discharged through a slightly open discharge valve, or some other provision must be
used to prevent overheating. If the pump runs for a few minutes without adequate flow through the pump, water may be
heated enough to scald someone when a valve is opened.

Body Assembly
Components
Automatic Piston Primer
The body is constructed of corrosion-resistant bronze and
other composite components.
Impeller
The impeller is constructed of bronze.
Impeller Shaft Assembly
The impeller shaft assembly consists of an impeller mounted on a stainless steel shaft with self-lubricated sealed
bearings.
The pump is equipped with two automatic piston primers.
For best performance, operate primers at 2000 rpm (pump
speed). The primers will still perform at lower speeds, but
priming time will increase. Operating the primers at speeds
greater than 2200 rpm will not significantly improve priming
time and can negatively affect service life of the priming
system. Primer may be equipped with a manual shut-off.
Thermal Relief Valve
The thermal relief valve opens 0 the temperature of the wa-
Pedestal (Primer Housing)
ter inside the pump reaches 49 C. The valve opens and di-
The pedestal is constructed of anodized aluminum and supports the piston primers and main bearings. Contains no oil
so no maintenance is required.
Mechanical Seal
The mechanical seal consists of a flat, highly polished
(lapped), self-adjusting (spring-fed) carbon ring that is
sealed in the pump body. The carbon ring presses against
a highly-polished rotating ring that is sealed to and rotates
with the impeller. Mechanical seal is retained in an easily removable seal housing.
Pump Drain
One ¾” drain with a ¼ turn manual valve is provided on the
volute.
verts water to one of the following locations:
To the holding tank, vehicle tank or to atmosphere (ground).
Tachometer Connection
A magnetic pick-up feeds the pump shaft revolutions to a tachometer which displays the pump impeller speed in revolutions per minute (four pulses per revolution).
Lubrication
No lubrication is required as the bearings are sealed, pedestal and primers are oil-free and the mechanical seal is maintenance free.

WARNING
Pressure Hazard. May result in personal injury.
Prior to connection or removal of hoses, caps or other closures with pump intake or pump discharge connections, relieve pressure by opening drains or bleeder valves. Bleeder
valves should also be used while filling a hose connected to
an intake with water.
WARNING
Scalding Water Hazard. May result in serious burns.
When operating the pump, be sure to open at least one discharge valve slightly to prevent the pump from overheating.
If the pump runs for a few minutes completely closed, it may
heat the water enough to scald someone when the valve is
opened. Overheating can damage the packing, seals and
other pump parts. If the apparatus builder has installed a bypass system or other provision designed to prevent overheating, opening a discharge valve may be unnecessary.
Operating Instructions
Pumping from Hydrant or in Relay
4. Open discharge valves and accelerate engine to obtain
desired discharge pressure and capacity.
5. Set low pressure relief valve or other governing device
to desired pressure (relief valve or governing device not
supplied by Waterous).
1. Open intake, hydrant and other valves as necessary to
allow water to enter the pump.
2. Allow about 30 seconds for water to flow into pump.
3. Engage pump drive in accordance with the vehicle operation instructions and accelerate engine to obtain desired discharge pressure and capacity.
NOTE: The S200-P pump has an automatic priming system that will engage or disengage when the discharge
pressure rises above or falls below a predetermined setting.
After Pumping
1. If pumping anything but clean water, remove all intake
and discharge caps, open all valves and open all drains.
Flush entire system with clean, fresh water for several
minutes to remove all traces of impurities.
2. Cycle the piston primers. Operate them until all the fluid
is discharged from the piston primer discharge pipes.
3. If pump is kept full of water when not in use, make sure
water is clean and non-corrosive. Make sure the pump
is completely full or completely drained (never partially
full).
4. Disengage pump drive in accordance with the vehicle
operation instructions.
5. Close all drains and install intake and discharge caps.
NOTICE
Freezing water hazard. May cause damage to the pump.
If the pump is exposed to freezing temperatures, drain all
water from pump, lines and accessories.
NOTICE
This pump has a mechanical seal, limit intake pressure to 75
psi (5 bar) if possible. Although the pump will operate properly
with higher intake pressure, such operation will greatly accelerate mechanical seal wear.
NOTICE
Do not attempt to pump more water than is available from the
hydrant or relaying pumper. Always make sure the intake
pressure compound-gage reading stays above zero. Some
fire departments operate at a minimum intake pressure of 15
psi (1 bar) when pumping from hydrant or in relay to prevent
a "soft" intake hose from collapsing.

Fire Hose Testing
WARNING
Hose Testing Hazard. May result in serious personal injury.
Due to a potential for catastrophic hose failure during service testing of fire hose, it is vital that safety precautions be taken to
prevent exposure of anyone to this danger. Fire pumps on fire department apparatus are not designed for and should not be
used for service testing of fire hoses. Hose testing machines should be used for service testing of fire hoses.
NFPA 1962 Standard for the Inspection, Care, and use of Fire Hose, Couplings, and Nozzles and the Service Testing of Fire
Hose provides requirements and testing procedures for service-testing fire hose at least annually. NFPA 1962 includes
procedures for service testing with either a hose testing machine or with a pump on a fire department fire apparatus.
WARNING
Pressure Hazard. May result in serious personal injury.
If a fire pump on a fire department apparatus is used for service testing of fire hoses, the procedures in NFPA 1962 MUST
be followed including the use of a fire department gate valve with a ¼-inch (6 mm) hole drilled through the gate installed
between the fire apparatus discharge outlet and the hose test layout to prevent a volume surge from the pump in the event a
hose bursts during testing.
During fire hose testing with a fire pump on a fire department fire apparatus, the fire pump is required to be operated at high
discharge pressure with little or no flow out of the apparatus.
WARNING
Scalding Water Hazard. May result in serious burns.
If a fire pump on a fire department apparatus is used for service testing of fire hoses, pump discharge water must be
circulated through a by-pass system or discharged through a slightly open discharge valve, or some other provision must be
used to prevent overheating. If the pump runs for a few minutes without adequate flow through the pump, water may be
heated enough to scald someone when a valve is opened.
CAUTION
If a fire pump on a fire department apparatus is used for service testing of fire hoses, operating the pump at high discharge
pressure with little or no flow may result in severe damage to the pump.

Maintenance
Mechanical Seal
Lubrication
Testing
NOTICE
An annual test should be performed to check pump performance. This will reveal the
condition of the internal components and if any repairs are required.
NOTICE
No lubrication is needed. The bearings are sealed, the primer and pedestal are oil-free
and the mechanical seal is lubricated by water..
NOTICE
Prolonged dry pump operation or operating a dry pump at high speeds will reduce the
life of the mechanical seal.
NOTICE
The pump shaft is sealed with a mechanical seal and no adjustment is required. When
the pump is in operation, the water being pumped lubricates and cools the seal. If the
seal leaks, replace the entire seal.
NOTICE
All pump maintenance can be performed using standard tools.
