Pump Speeds For Various Viscosities
Enter the VSG Chart below at the appropriate
pumpage viscosity value (SSU /CPS), read across
to the desired capacity, where you will find
the correct model, recommended pump speed
and the minimum suction piping size.
Caution: Suction piping
diameter must be separately determined, regardless
of pump port size, where volatile liquids
or viscous pumpage are concerned. For very
viscous fluids, liquid levels should be high
enough above pump centerline to assure positive
pressure ("Flooded Suction") at
all times.
