INTRODUCTION
Thank You for purchasing a TORO pump. Read this
manual carefully to learn how to safely install and
operate your pump. Failure to do so could result in
personal injury or damage to the pump.
Because pump installations are seldom identical, this
manual cannot possibly provide detailed instructions
and precautions for every aspect of each specific
application. Therefore, it is the responsibility of the
owner/installer of the pump to ensure that
applications not addressed in this manual are
performed only after establishing that neither
operator safety nor pump integrity are compromised
by the installation. Pumps and related equipment
must be installed and operated according to all
national, local and industry standards.
If there are any questions regarding the pump or its
application which are not covered in this manual or in
other literature accompanying this unit, please
contact your TORO distributor;

source, contact the power source manufacturer's
local dealer or representative.

SAFETY
SAFETY −SECTION A
This information applies to TSP series basic
pumps. TORO has no control over or
knowledge of the power source which will be
used. Refer to the manual accompanying the
power source before attempting to begin
operation.
This manual will alert personnel to known
procedures which require special attention,
to those which could damage equipment,
and to those which could be dangerous to
personnel. However, this manual cannot
possibly provide detailed instructions and
precautions for each specific application or
for every situation that might occur during
maintenance of the unit. Therefore, it is the
responsibility of the owner, installer and/or
maintenance personnel to ensure that
applications and/or maintenance
procedures not addressed in this manual
are performed only after establishing that
neither personal safety nor pump integrity
are compromised by such applications or
procedures.
Before attempting to open or service the
pump:
1. Familiarize yourself with this manual.
2. Disconnect or lock out the power
source to ensure that the pump will
remain inoperative.
3. Allow the pump to completely cool if
overheated.
4. Check the temperature before opening
any covers, plates, or plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cautiously.
7. Drain the pump.
This pump is designed to handle liquids
containing large entrained solids or slurries.
Do not attempt to pump volatile, corrosive,
or flammable materials which may damage
the pump or endanger personnel as a result
of pump failure.
Death or serious personal injury and
damage to the pump or components can
occur if proper lifting procedures are not
observed. Make certain that hoists,
chains, slings or cables are in good
working condition and of enough capacity
and that they are positioned so that loads
will be balanced, and the pump or
components will not be damaged when
lifting. Suction and discharge hoses and
piping must be removed from the pump
before lifting. Lift the pump or component
only as high as necessary and keep
personnel away from suspended objects.
After the pump has been positioned, make
certain that the pump and all piping
connections are tight, properly supported
and secure before operation.

SAFETY
Overheated pumps can cause severe burns
and injuries. If overheating of the pump
occurs:
1. Stop the pump immediately.
2. Ventilate the area.
3. Allow the pump to completely cool.
4. Check the temperature before opening
any covers, plates, gauges, or plugs.
5. Vent the pump slowly and cautiously.
6. Refer to instructions in this manual
before restarting the pump.
Never run this pump backwards. Be certain
that rotation is correct before fully
engaging the pump.
Pumps and related equipment must be in-
stalled and operated according to all
national, local and industry standards.

SAFETY
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested before
shipment from the factory. Before installation, inspect
the pump for damage which may have occurred during
shipment. Check as follows:
a)Inspect the pump for cracks, dents, damaged
threads, and other obvious damage.
b)Check for and tighten loose attaching hardware.
Since gaskets tend to shrink after drying, check
for loose hardware at mating surfaces.
c) Carefully read all warnings and cautions
contained in this manual or affixed to the pump,
and perform all duties indicated. Note the
direction of rotation indicated on the pump.
Check that the pump shaft rotates
counterclockwise when facing the impeller.
Only operate this pump in the direction
indicated by the arrow on the pump body and
on the accompanying decal. Refer to
Rotation in OPERATION, Section C.
d) Check levels and lubricate as necessary. Refer
to LUBRICATION in the MAINTENANCE AND
REPAIR section of this manual and perform
duties as instructed.
e) If the pump and power source have been stored
for more than 12 months, some of the
components or lubricants may have exceeded
their maximum shelf life. These must be
inspected or replaced to ensure maximum
pump service.
If the maximum shelf life has been exceeded, or if
anything appears to be abnormal, contact your TORO
distributor or the factory to determine the repair or
updating policy. Do not put the pumpinto service until
appropriate action has been taken.
POSITIONING PUMP
Death or serious personal injury and
damage to the pump or components can
occur if proper lifting procedures are not
observed. Make certain that hoists, chains,
slings or cables are in good working
condition and of sufficient capacity and
that they are positioned so that loads will
be balanced, and the pump or components
will not be damaged when lifting. Suction
and discharge hoses and piping must be
removed from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away from
suspended objects.
Lifting
Pump unit weights will vary depending on the mounting
and drive provided. Check the shipping tag on the unit
packaging for the actual weight and use lifting equipment
with appropriate capacity. Drain the pump and remove
all customer-installed equipment such as suction and
discharge hoses or piping before attempting to lift
existing,installed units.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mounting is
essential for proper operation.
The pump may have to be supported or shimmed to
provide for level operation or to eliminate vibration.
Clearance
It is recommended that 18 inches (457 mm) of clearance
be provided in front of the back cover to permit removal
of the cover and easy access to the
pump interior. A minimum clearance of 8 inches (203
mm) must be maintained to permit removal of the cover.

SAFETY
SUCTION LINES
To avoid air pockets which could affect pump priming, the
suction line must be as short and direct as possible.
When operation involves a suction lift, the line must
always slope upward to the pump from the source of the
liquid being pumped; if the line slopes down to the pump
at any point along the suction run, air pockets will be
created.

Suction Line Positioning
The depth of submergence of the suction line is
critical to efficient pump operation. Figure 2 shows
recommended minimum submergence vs. velocity.
NOTE
The pipe submergence required may be reduced by
installing a standard pipe increaser fitting at the end of
the suction line. The larger opening size will reduce the
inlet velocity. Calculate the required submergence
using the following formula based on the increased
opening size (area or diameter).
