ROTATION: Viking Mag Drive® pumps are designed to run
in either direction. See “Pump Rotation”, page 10.
PRESSURE RELIEF VALVES:
1. Viking pumps are positive displacement pumps and
must be provided with some sort of pressure protection.
This may be a relief valve mounted directly on the pump,
an inline pressure relief valve, a torque limiting device
or a rupture disk. Do not rely on decoupling of magnets
for protection from over pressure; this may result in
damage to the magnets, pump, or other equipment.
2. Relief valves are mounted as standard on the casing of
all pumps.
3. If the pump rotation is to be reversed during operation,
pressure protection must be provided on both sides of
the pump.
4. The relief valve adjusting screw cap must always point
towards the suction side of the pump, see Figure 2.
If the pump rotation is reversed, remove the pressure
relief valve and turn end for end (see “Pump Rotation”,
page 10).
5. Pressure relief valves cannot be used to control pump
flow or regulate discharge pressure.
For additional information on pressure relief valves, refer to
Technical Service Manual TSM000 and Engineering Service
Bulletin ESB-31.

MAINTENANCE
Series 8124A, 8123A and 8127A pumps are designed
for long, trouble-free service life under a wide variety of
application conditions with a minimum of maintenance. The
points listed below will help provide long service life.
CLEANING PUMP:
Keep the pump as clean as possible. This will facilitate
inspection, adjustment and repair work.
LUBRICATION:
Bracket bearings require external lubrication. This must be
applied slowly with a handgun to lubrication fittings every
500 hours of operation with multi-purpose grease, NLGI # 2.
Do not over-grease. Applications involving very high or low
temperatures will require other types of lubrication. Refer to
ESB-515. Consult factory with specific lubrication questions.
STORAGE:
If the pump is to be stored, drain and pour non-detergent
SAE 30-weight oil (or compatible alternative) into the pump
port. Apply grease to the pump shaft, if accessible. Viking
suggests rotating the pump shaft every 30 days to circulate
the oil in the pump. The pump should be stored in a dry area.
SUGGESTED REPAIR TOOLS:
The following tools are required to properly repair series
8124A, 8123A and 8127A pumps. These tools are in addition
to standard mechanics’ tools such as open-end wrenches,
pliers, screwdrivers, etc. Most of the items can be obtained
from an industrial supply house.
1. Soft face hammer
2. Allen wrench set (SAE)
3. Torque wrench with a locknut socket
4. Two feeler gauge sets
5. Arbor press
6. Brass bar
7. Hook style spanner wrench
8. Canister Sleeve (3-810-025-999-00)
9. Inner Magnet Lift (3-810-026-999-00)
10. Bearing Housing Lift (Figures 3 and 9)
