BALL BEARINGS

(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 250 PSI (17 BAR).
Bearings are “Sealed for Life”.

PRESSURE LUBRICATION

(Standard Equipment)
(“AS”, “AK”, “AL” Sizes)
A patented pressure lubrication
system automatically lubricates the
idler bushing. This system provides
a constant film of liquid between the
idler bushing and idler pin at a pressure equal to the pump discharge
pressure regardless of pump rotation.

DUCTILE IRON PARTS

(Standard Equipment)
(“AS”, “AK”, “AL” Sizes)
Internal pumping gears (rotor and
idler) are constructed of ductile iron
for added strength in handling all
types of liquids up to 15,000 SSU
(3,300 cSt). “HL” size rotor also
furnished in ductile iron.

O-RING GASKETS

(Standard Equipment)
O-Ring gaskets are used between
casing and head plate and between
casing and relief valve or valve
plates. Flat valve gaskets furnished
on “G”, “GG”, “H”, “HJ” and “HL”
size pumps. These gaskets provide
a positive seal eliminating a chance
for leakage at these points.

Viking’s high-speed, heavy-duty Series 4195 pumps
are available in capacities up to 75 GPM. These pumps
can be furnished directly connected to a 50 Hz or 60 Hz
motor. (See Series 4195D units shown on page 144.3.)
All eight sizes of Viking Series 4195 pumps are furnished
with single mechanical seals. This seal is a simple selfadjusting, non-leak method of shaft sealing located
ahead of the casing ball bearing. The Series 4195
pumps are built for con­inuous or intermittent duty for
t
such applications as filtering, circulating, transferring,
or booster service in general industrial, petroleum and
marine uses. NOTE: “UL” listed pumps for handling LPGas require special construction. Externals are high
strength cast iron. (Ductile Iron Casing on “AS”, “AK”
and “AL” sizes). See Catalog Section 440 for details and
pricing information. Model numbers for these pumps
must be designated by a suffix -G, eg. GG4195-G or
when used with a “D” drive, GG4195D-G. “UL” listed
models must be equipped with a return-to-tank pressure
relief valve. Maximum discharge pressure for “UL” listed
models is 125 PSIG.
① Values shown represent minimums or maximums. Some special construc­ion or
t

consideration may be required before a cataloged pump can be ap­ lied to an
p
application involving maximum pressure or minimum or max­mum temperature
i
and/or viscosity. Certain models have restrictions in pressures and/or viscosities.
See specifications, page 144.2, and perform­ nce curves, which can be

electronically generated with the Viking Pump Selector Program, located on

② Nominal capacities based on handling thin liquids.
Metric conversions are based on US measurements and rounded to the nearest
whole number.
