PUMPING ELEMENTS

(Standard Equipment)
Pumps are equipped with inner cas­
ing ball bearing installed outside of
mechanical seal and a radial thrust
ball bearing permitting heavy-duty
service up to 200 PSI (14 BAR).
Bearings are “Sealed for Life”.

(Standard Equipment)
Internal pumping gears are constructed of type 316 and type 770
Stainless Steel alloy. This allows
high speed, non-galling operation,
handling all types of liquids up to
25,000 SSU (5,500 cSt). PPS composite idlers are also available for
thin liquid applications.

BALL BEARINGS

(Standard Equipment)
All Series 4197 pumps are furnished
with a positive drive mechanical
seal. The seal is a simple, selfadjusting, non-leak method of shaft
sealing. It is especially suited for
handling liquids such as alcohols,
solvents, etc.

(Standard Equipment)
Permits bypassing of liquid from
discharge to suction side of pump.
Prevents build up of pressure in
discharge line. “GG,” “HJ” and “HL”
size valve mounts on pump head.
“AS,” “AK” and “AL” size valve
mounts on pump casing.

(Nominal Rating)

Viking’s heavy-duty Series 4197 pumps are available
in capacities of 10, 20, 30, 35, 50 and 75 GPM. All are
built for high-speed handling of thin liquids requiring
stainless steel construction. These pumps are ideal for
such liquids as solvents, alcohols and similar liquids.
The three smaller size pumps can be furnished directly
connected to either 1800 or 1200 RPM motors. The
three larger sizes are directly connected to 1200 RPM
motors. (See Series 4197D units shown on page
164.3.) All six sizes of Viking Series 4197 pumps are
furnished with single mechanical seals. This seal is a
simple self-adjusting, non-leak method of shaft sealing
located ahead of the casing ball bearing. The Series
4197 pumps are built for con­inuous or intermittent duty
t
for such applications as filtering, circulating, transferring
or booster service in chemical, general industrial,
petroleum and petrochemical uses.
① See following pages or consult factory for specific recommendations.
② Nominal capacities based on handling thin liquids at 1800 RPM on three small
sizes, 1200 RPM on three large sizes.

③ Solvents, alcohols, aqueous solutions and similar liquids.
Metric conversions are based on US measurements and rounded to the nearest whole number.
