MP PUMPS HTO SERIES
APPLICATION AND INSTALLATION INSTRUCTIONS
Application assistance and technical
information can be obtained by calling
MP PUMPS at 586-293-8240.
The HTO pump is designed for pumping high
temperature fluids that are non-corrosive,
non-volatile, and have good lubricating
qualities.
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.
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.
6. The installation should permit adequate
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 adaptor and motor. The motor and/or
pump seal may fail from excessive heat.
8. A good installation will have an enclosure that
provides adequate air flow of ambient air to the
motor of the pump.
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 the 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, vibrating, or
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.
