World Wide Experience
on Process Pumping
Services
When Goulds developed the 3180/85 we utilized
140 years of pump design experience to ensure it
would have unmatched mechanical reliability.
Today, installations around the world attest to its
remarkable performance.
The 3180/85 ... the heavy duty process pump
designed to handle all of your tough process
pumping applications.

Models 3180/85 Paper Stock/Process Pumps
Heavy Duty Design Features for Handling the Toughest Services
LUBRICATION
FLEXIBILITY
The preferred
lubrication of oil is
standard. No special
parts required to
convert to grease .
SEALING FLEXIBILITY
Choice of mechanical seal
(illustrated), packed box or
dynamic seal.
TAPERBORE TM
PLUS SEAL CHAMBER
Wide range of sealing arrangements available
to meet service conditions. Patented seal
chambers improve lubrication and heat
removal (cooling) of seal faces for extended
seal life and pump uptime.
LABYRINTH
SEALS
Unique Goulds design
prevents premature
bearing failure caused
by lubricant
contamination and
loss of lubricant.
CASING
• Top centerline discharge
for air handling and
self-venting. Special
volute design reduces
radial loads.
• Back pull-out design.
• Foot-mounted.
CONTINUOUS
HIGH
PERFORMANCE
Original high
efficiency maintained
by simple external
impeller adjustment
resulting in long term
energy savings.
HEAVY DUTY
SHAFT
Designed for minimum
deflection at maximum
load. Dry shaft
achieved by sealing
from pumpage by
O-rings at sleeve and
impeller nut.
RIGID FEET
Large casing and
bearing frame feet
maintain driver
alignment with high
pipe loads; absorb
system vibration.
RENEWABLE
SUCTION
SIDEPLATE
With open impeller
design minimizes
maintenance costs.
Positively sealed with
O-ring and gasket.
OPEN IMPELLER
Full back shroud and thick impeller vanes
for handling slurries and stringy fibers. Large
balance holes and back pump-out vanes
minimize stuffing box pressure and axial
thrust. Optional enclosed impeller available.

Power Ends Designed for
Maximum Reliability
Power End Reliability is vital when thinking about pump mean
time between failure (MTBF). To ensure maximum bearing
life, the 3180/85 follows three key bearing design factors:
1. Bearing Design Life
2. Bearing Temperature
3. Bearing Environment
Bearing Design Life
Bearing manufacturers state that skidding, cage stresses
and oil temperatures can greatly reduce the bearing life of
oversized bearings. The “right” size bearing is vital to overall
bearing life.

Bearing Size
Bigger is NOT always better!
Bearings are often oversized because pump designers often estimate
bearing loads. Goulds measured their loads on test and chose bearing
designs that would enable bearing life of 100,000 hours.
Bearing Temperature
Keeping the pump loads minimized and selecting
the “right” bearing will keep bearing temperature
under control.

3180/85 bearing temperatures average only 120˚F/50˚C!

Bearing Environment
Labyrinth oil seals are standard
Contamination being the second leading cause
of bearing failure requires special attention.
Common lip seals were not considered due to
their 2,000 hour design life. After wearing out,
there will be an open passage way for
contamination. For this reason our 3180/85 is
provided with labyrinth oil seals as standard. We
picked carbon filled Teflon ® since it is durable
and impervious to corrosion.

RIGID FRAME FOOT
Heavy duty foot reduces
effects of pipeloads/
thermal expansion on
bearing life. Bearings
continue to run cool.
Our labyrinth seals were put through a series of
“torture” tests to see how well they would perform.
Only the Goulds seal passed every test while
other competitive labyrinth seals failed.
LARGE OIL
SIGHT GLASS
The standard oil
sight glass assures
oil level is properly
set and maintained.
Condition

easily monitored.
