oil may occur.
•
DO NOT operate the pump in a manner that it
was not intended to be use.
•
DO NOT install for use in an open environment
where people are present.
•

unusual noise or vibration occurs.
• DO NOT operate beyond the pressure or
temperature limits stated in the product
literature, see form 9050.
•
DO NOT allow severe temperature
changes to occur in a short time period

APPLICATION AND INSTALLATION INSTRUCTIONS
Application assistance and technical
information can be obtained by calling
MP PUMPS at 800-563-8006.
The HTO pump is designed for pumping high
temperature fluids that are non-corrosive,
non-volatile and have good lubricating qualities.
INSTALLATION AND START-UP
INSTALLATION
1. The pump must be installed in a horizontal shaft
position.
2. The housing may be rotated to a horizontal or
vertical discharge to fit the particular piping
installation.
3. Rigid and supported piping must be used that
will not strain the pump housing when
temperature changes are made during the use
of the pump.
4. The piping system must be free of foreign
material and moisture before start-up.
5. Pipe thread sealing compound must be used on
the NPT flanges that is compatible with the fluid
being pumped and is rated for the temperature
requirements.
The installation should permit adequate
6.
circulation of air to provide proper cooling of the
motor and pump seal housing.
7. Do not install in a sealed enclosure or insulate
the pump adapter and motor. The motor and/or
pump seal may fail from excessive heat.
The primary application for use is with heat
transfer oils.
It is the users' responsibility to determine the
pump and product compatibility with the materials
of construction.
START-UP
1. Follow all requirements and recommendations
from the heat transfer fluid manufacturer for fill,
start-up and use.
2. Check for leaks before insulating the piping
system.
3. Check for proper shaft rotation by jogging the
power and observing the fan clamp. Rotation
arrows are provided on pump housing.
4. The seal cavity inside the pump will internally
vent during fill and start-up.
5. A small amount of oil may leak from the seal
cavity at the shaft; this is normal for a new
installation and will stop after approximately one
hour.
6. Do not allow the pump to run dry, or continue to
operate the pump when it is noisy
leaks are observed. These noticeable signs give
a warning that something is wrong with the
equipment and must be investigated to avoid
possible damage or injury from burns caused by
hot oil.
, vibrating, or
8. A good installation will have an enclosure that
provides adequate air flow of ambient air to the
motor of the pump.

OPERATION AND MAINTENANCE
Thermal oil vapors leaking from a system can be
highly flammable.
Any system leak should be repaired immediately.
Do not insulate the pump or system piping with
porous flammable insulation. Fluid may wick,
decompose and spontaneously ignite.
Ideal mechanical seal life is 20,000 hours.
Reduced seal life may be experienced from
extreme conditions.
Recommended spare parts and service parts to
rebuild the HTO-120 are:

At disassembly, check the impeller and other wear
items for unusual wear. Replace if necessary.
When servicing the pump, care should be taken
that the pump has cooled to a sufficient
temperature to permit disassembly. The product
should be drained from the pump housing and
disposed in accordance with the fluid
manufacturer's recommendations. Operating
personnel should be warned to exercise care and
utilize eye and skin protection when servicing the
pump.

HTO 120 ASSEMBLY INSTRUCTIONS
1. Assemble drive sleeve #11 (29781), impeller
#1 (29770) and nut #3 (22655).
2. Thread pipe plug #16 (21255) into housing
#14 (26587).
3. With the housing on the bench, suction down,
place the impeller and drive sleeve assembly
into the housing.
4. Assemble the adaptor #9 (29160) to the
housing with gasket #15 (31518) between
them. Use six 3/8-16 studs #18 (21261),
washers #17 (21266), and hex nuts
#25 (21241).
5. Install three gaskets #6 (29165), two carbon
isolators #10 (29158) and one O-ring #8
(29230) onto drive sleeve. The O-ring and one
gasket go between the two carbon isolators.
The second gasket goes between the carbon
isolators and the adaptor. The third gasket goes
between the carbon isolator and the seal
housing.
6. Assemble seal #2 (29773) onto the drive sleeve
with a liberal amount of grease to prevent the
seal from being damaged.
7. Press the lip seal #13 (29774) into the seal
housing #12 (29772), flat side down. Press the
seal seat into the seal housing flush against
the lip seal.
8. Assemble the seal housing #12 (29772) to the
adaptor #9 (29160) with three 5/16-18
screws #5 (29178). As steady pressure is
applied to the seal housing to hold it in
place, thread the three 5/16-18 screws in
and torque them to 25 inch-lbs. each.
Working around the bolt circle tighten the
screws in 25 inch-lbs. increments until each
screw is tightened to 150 inch-lbs.
9. Assemble fan clamp #4 (29775) to drive
sleeve.
10. Assemble the pump to the motor
motor onto the pump. Install and tighten the
four mounting screws. Push the impeller
towards the motor until it stops (contact with
the impeller and isolater). Tighten the drive
clamp screws to 120/140 inch-lbs. and install
piping.
. Slide the
NOTE:
Follow oil manufacturers guide for fill
and start-up. The seal cavity will vent
internally during start-up.
