Please read this guide carefully before installing and operating the Model 500P
THERMAFLOW system.
HYDRAULIC FUNCTION
The Model 500P THERMAFLOW assembly is designed to cool and filter the
oil required to operate your hydraulic system by using the product which is being
pumped. This is accomplished via a special heat exchanger which is designed to
transfer the heat of the hydraulic oil into the product which is being pumped. The
amount of heat which is transferred into the product is safely limited only to the
amount of cooling which is required. The product supplied to the heat exchanger by a
pressure line which is tee’d into the pressure discharge line. STAC, INC. provides an
orifice fitting to be installed in the THERMAFLOW unit to limit the amount of product
being pumped through the heat exchanger. The exhausting product is then pumped
back into the supplying vessel through a suitable port (ex. motor fuel port).
Optional hydraulic controls for this system allow for easy integration with off-
truck remote controls for either electric or air shut-offs.
And as with all hydraulic drive systems, this system will also eliminate the need
for a driveline. This will reduce maintenance and downtime associated with shaft
driven pumps.
TANK STABILIZER FUNCTION
The Model 500P THERMAFLOW is also a tank stabilizer. As the propane is
pumped through the heat exchanger it is vaporized. Reintroducing this vaporized
product back into the supplying vessel gives the added benefit of maintaining pump
performance, reducing pump noise and prolonging pump life.
Because different product pump applications require different speed and power
requirements, your THERMAFLOW system was custom engineered for a particular
application. If the system is operated beyond its designed capacity, overheating and/
or component damage could result.
