Before opening any Viking pump liquid
chamber (pumping chamber, reservoir,
relief valve adjusting cap fitting, etc.)
Be sure:
1. That any pressure in the chamber has
been completely vented through the
suction or discharge lines or other
appropriate openings or connections.
2. That the driving means (motor,
turbine, engine, etc.) has been “locked
out” or made non-operational so that
it cannot be started while work is
being done on pump.
3. That you know what liquid the
pump has been handling and the
precautions necessary to safely
handle the liquid. Obtain a material
safety data sheet (mSDS) for the
liquid to be sure these precautions
are understood.
failure to follow above listed
precautionary measures may result in
serious injury or death.
This bulletin deals exclusively with Pump Models C, F, FH32
and C, F, FH432 General Purpose Pumps. Refer to figures
1, 2, 5, and 7 for general configuration and nomenclature
used in this bulletin.
All pumps can be furnished with either a mechanical seal or
packing. A mechanically sealed pump can be changed to a
packed pump by removing the mechanical seal and inserting
the packing spring, inner packing gland, packing and outer
packing gland. The mechanical seal pump is dimensionally
interchangeable with the packed pump.
