INTRODUCTION
General
The following items must be considered prior to pump
installation:
1. Location - locate the pump as close as possible to the
supply of the liquid being pumped. If possible, locate
the pump below the liquid supply. Viking pumps are self
priming; but, the better the suction conditions, the better
the pump will perform.
2. Accessibility - the pump must be accessible for
inspection, maintenance and repair.
3. Suction/Discharge - Hi-Low Double pumps are
designed for clockwise rotation only (viewed from shaft
end). Refer to Figure 1.
4. Pump Life - pump life is a factor of many parameters,
mainly pressure, speed and duty cycle. Temperature,
contamination and type of hydraulic oil also have a
definite effect.
5. Hydraulic Oil - Viking recommends using industrial
grade hydraulic oil. Temperature must not exceed 150
ºF for optimum life of hydraulic oil. Operating viscosity
must be between 100 and 300 SSU.
6. Filter / Strainer - on a hydraulic system, use a return
line filter with a maximum 10 micron rating to keep the
system clean and free of contaminating elements. A 100
mesh strainer is recommended in the suction line.
7. Pressure Relief Valve - a pressure relief device must
be installed in the system to provide over-pressure
protection. If a line is blocked or closed, pressure builds
up until the motor stalls, drive equipment fails, a pump
part breaks or piping bursts.
8. Discharge Line - select discharge piping, hoses and
fittings rated for maximum system pressure.
9. Storage - if the pump is to be stored, drain the pump and
apply a light coat of non-detergent SAE 30 weight oil to
all internal pump parts. Apply grease to the pump shaft
extension. Viking suggests rotating the pump shaft by
hand one complete revolution every 30 days to circulate
the oil.

REPAIR
1. Parts For A Preventative Maintenance Program -
- Mechanical Seal or Lipseal(s) (Not applicable for Mag
Drive pumps)
- O-rings
2. Parts For A Major Overhaul - The Viking Spur Gear
series pumps have very tight clearances and precision
machining tolerances, and wear on any of the parts will
typically indicate that most of the critical parts are worn.
Therefore, if wear is found on any of the pump parts,
Viking recommends replacing the entire pump. Always
supply the serial number from your pump nameplate
when requesting a replacement.
