HTO Pump – How It Came To Be
 The HTO 80 was developed in the early 1990’s…
 Developed to pump hot oil thru commercial food
preparation equipment
 Led to our patented design
 HTO pump line has grown into the four models used
today
 HTO products serve in multiple markets today
 Tempuflo™ is a registered trademark representing the
HTO series of pumps.

HTO Pump – Sales vs. Competition
 Cost leader vs. competition
 Compact size requires less space than competition
 No cooling water needed, reduces auxiliary equipment,
and opportunity for oil/water mixing
 Close coupled-no shaft alignments-less hassle
 No sleeve bearings to wear out
 Impeller is closer to supporting bearing
 Less heat transferred out of the system; less energy
required to be replaced

HTO Pump – Reliability – Longer MTBF
 Lower temperatures in the seal cavity greatly improves
mechanical seal life
 HTO pumps lower seal cavity oil temperatures (<350°F)
 Coking between faces accelerates seal wear and
shortens seal life
 Lower temperatures, less coking, longer seal life, longer
MTBF
 Longer MTBF, less maintenance costs
 HTO pumps provide several thousands of hours service
life between rebuilds.

HTO Pump – System Applications
 DRYERS - used to evaporate liquids
from solids (mining, food, printing,
paper).
 EXCHANGERS - transfer of energy
between fluids of differing
temperatures (chemical,
pharmaceutical, plastics, metals,
polymers, melting).
 LINE TRACING - hollow tube or
jacket on outside of pipe to keep
material inside warm (plastics,
asphalt, food).
 MIXERS - outside of mixer is heated
with hot fluid keeping material viscous
(chemical, food, pharmaceuticals).

HTO Pump – System Applications
 MOLDS – keeps plastic molds hot allowing
material to flow evenly through mold cavities.
 OVENS – used on hot oil moving through
cooking/baking coils.
 PRESSES – platens are heated for bonding
(plywood, rubber, circuit boards).
 ROLLS – Hot oil circulates through rolls that
press and bond laminates.
 TANKS / VESSELS – Hot oil circulates
through jackets around holding tanks.

HTO Pump – Markets Served
HTO markets to expand:
 Asphalt plants – there are approximately 3600 asphalt
plants in the United States and over 90% of our
countries 2 million miles of roads are asphalt
 Laminating processes – laminated countertop, floor
coverings, furniture, and wood door manufacturers
 Recycling – recycling processes ranging from oil to
tires
 Solar energy – heat transfer fluid moving heat thru the
system

HTO Series – Frequently Asked Questions
Q: How can I pump hot oil above 400°F and have a Viton fitted seal survive?
A: The seal in the HTO pump runs in a cooled environment where the
temperature will be less than 350 degrees.
Q: When the pump is stopped at temperature will the seal temperature
spike?
A: Even though the seal is cooled by a fan attached to the shaft when the pump is
stopped the seal temperature will not spike. The seal cavity temperature will fall
due to the low thermal conductivity isolation system. Controlled temperature
ramp down is not required.
Q: Can the pump be mounted vertically?
A: Yes but the seal cavity may need to be vented on cold startup to remove the air
trapped inside so that the seal does not run dry.
Q: Where should the pump be installed in the system?
A: The HTO pump should be installed downstream of the heating load and at a
low elevation point in the system where the flow leaving the pump will be
pumped into the heater. Isolation valves for the pump are recommended.

HTO Series – Frequently Asked Questions (cont.)
Q: Will the motor bearings be affected by the heat from the pump?
A: The ball bearing will have a higher temperature than when installed onto a
conventional pump. In most cases the bearing temperature will not exceed
180°F
Q: On initial start-up will the seal run dry?
A: No, but there will be air inside the seal cavity that will move out into the normal
process flow path over time. The best system fill technique is to bottom fill the
system to remove the most air during the fill.
Q: Can the pump be insulated?
A: Yes, but only the pump housing as the rest of the pump needs to have air
circulate over it for cooling.
Q: Can the pump be mounted inside a closed cabinet?
A: Yes, but the temperature inside the cabinet must not exceed the operating
temperature of the electric motor. Good practice is to ventilate the cabinet at the
fan cover of the motor for inlet air and locate exhaust vents near the pump
housing. Higher ambient temps will increase the seal temperature.

HTO Series – Frequently Asked Questions (cont.)
Q: Can the HTO pump be used in applications where the process
temperature varies?
A: Yes, the seal temperature will not vary as greatly as the process because of
the isolation design.
Q: Is MTBF predictable?
A: Every application is different including the quality of the oil. MTBF can be
monitored initially and then it should be repeatable assuming that the oil and
other system parameters are consistent.
Q: How important is oil quality to the life of the pump seal?
A: The quality of the oil is as important to the seal as dirt and contamination is to
a ball bearing. If the process is made to conform to the oil manufacturers
recommendations seal life may approach several years of continuous use.
Q: Can the HTO pump be operated at 1750 RPM’s?
A: Yes, while the speed at which the integral fan clamp is turning is slower, it still
moves enough air across the seal housing to remove an acceptable amount of
heat. It is important to remember that due to the design of the pump the
isolator bushings are the major factor in protecting the mechanical seal
against the high process temperature.
