Important!
The 1/8” rinsing connection on both sides serves to place a separating agent (e.g.
DOP) behind the medium seal on the suction side. This stops leakage (e.g. with Iscocyanate)
from crystallizing. When pumping different types of Freon, the pressure in the rinsing system
should be approximately 7.25 PSI (0.5 bar) higher than on the suction side of the pumped me-
dium.
To vent the pump easily on the discharge side, it is recommeded to install a T-piece with a high-
pressure cut-off tap as close as possible to the discharge port.
HORSEPOWER RATINGS:
The rating shown are the power
requirements for the pump. Gas engine
power outputs must be approximately
twice the pump power requirements
shown above.
We recommend a 1.15 service factor be
specified when selecting an electric motor as
the power source. To compute specific pump
horse power requirements, use the following
formula:
HP = (GPM X PSI) / 1450
