Suction piping for viscous liquids
Specific technical information is required for the installation of
pumps intended for metering viscous liquids:
For this kind of application we recommend stainless steel
l
pumpheads.
Spring-loaded discharge valves are also recommended in the
l
event of high-viscosity liquids.
The suction piping must have an adequate diameter; as a rule, for
l
high-viscosity liquids (2000 cps), select the size immediately above
the diameter of the pump suction connections.
In any case, when viscous liquids are to be metered choose for
l
the pipe at least the same size as that of the pump connections.
