Inlet and Return Oil Piping Connections
The oil inlet and outlet connection sizes are 1” FNPT. The user suction and discharge line sizes
(either schedule 40 (min) pipe or smooth I.D. hose) should be ¾” I.D. minimum and 2” I.D.
maximum to ensure that no flow restrictions will occur due to line lengths, high viscosity, etc.
When processing high viscosity oils, the larger sizes of pipe or hose should be used. If tubing is
used, increase the diameter by at least one size. All connections should be tight and free of air
leaks.
If a flooded suction to the ThermoJet Oil Purifier is not practical, ensure that the suction height
from the reservoir drain to the inlet connection of the Thermo
Jet
is no more than 8 feet (2.4
meters) above the minimum oil level in the reservoir.
If the suction lift exceeds 8 feet (2.4 meters), install a foot-valve or foot-pump to ensure that the
suction pump will prime and hold prime during long-term service.
Ensure that the oil return connection is above the oil level in the reservoir to prevent back flow
and flooding of the separation tank when the Thermo
Jet
is not operating. Return oil must be
introduced into the reservoir above the oil level to prevent siphoning when the Thermo
Jet
is not
operating.
NOTICE:
Even very small air leaks can dramatically affect pump suction
performance
