SPECIAL INFORMATION

DANGER !

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 manual deals exclusively with Pump Models C, F,

FH56M and C, F, FH456M General Purpose Pumps. Refer

to Figures 1, 2, 4, and 7 for general configuration and

nomenclature used in this bulletin.

All pumps can be furnished with either a mechanical seal or

packing. Packed pumps are furnished with suitable packing

for the liquid pumped. A seal 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.
