Superior Design                                                  

Before selecting A Process Pump...                                      

Consider the Four Design Features For Extended Pump Performance

In order to select a chemical process pump wisely, consideration must be given to design features that provide long-term reliable performance.

The pump must be designed for optimum shaft seal and bearing life to prevent the failure of these two primary causes of pump downtime.

A IMPELLER
Must be designed for long-term, maintainable performance

and minimum hydraulic loads for maximum reliability.

B SEAL CHAMBER
Must be designed for favourable seal environment —

proper heat dissipation and lubrication of seal faces.

The design must also be able to handle tough services:

liquids containing solids, air or vapours.

C POWER END

Must be designed for optimum bearing life, effective oil

cooling, and minimum shaft deflection. Onboard condition

monitoring provides early warning of potential failures,

before they occur.

D BASEPLATE
Must be rigid, and able to withstand forces and moments of plant piping systems.

Consider the Total Cost of Ownership                                                      

Consider the fact that over a 20-year ANSI pump life, 92% of the total  costs are maintenance, operation and installation. Only 8% is the initial pump purchase cost.

Select a process pump that maximizes reliability (low

maintenance cost), has long-term maintainable hydraulic

performance (low operating cost) and is installed on a

rigid baseplate.

Energy and maintenance costs during the life of a process

pump can be more than 10 times its purchase price.

Fully Open Impeller                                                                                              

Acknowledged Best Design for CPI Services

The open impeller is the acknowledged best design for process services. It is ideally suited for corrosives/erosives, liquids containing solids and stringy materials. The most reliable pumps feature

open impellers as standard.

See The Difference

Remarkably, Goulds had performance in mind when the Model 3196

standard dimension process pump was developed in 1959. Of timely

significance was the decision to feature a fully open impeller rather

than an enclosed type. There are three excellent
reasons why:

• Greater wear area for longer life
• Renewable performance for reduced repair costs

• Minimum hydraulic loads for maximum mechanical reliability

Two Times More Wear Area

Longer Life, Reduced Repair Costs

The most critical wear areas of a pump are the casing and stuffing box/seal chamber clearances. At a given

wear rate, the larger wear area means longer life.

Wear Area Calculation (10 inch dia. impeller)
Area Wear Surface = Π r2 = Π(5)2 = 79 in2
Total Wear Area (Front & Back) = 2 x 79 = 158 in2

Area Nose Ring = 2 Π rW = 2 x Π x (.9) (.9) = 5 in 2
Area Back Cover = Π r 2 = Π (5)2 = 79 in2
Total Wear Area = 5 + 79 = 84 in 2

Maintained High-Performance

Long Pump Life

It is common knowledge that as a pump wears, the performance decreases. Goulds open impeller can

be adjusted, simply and quickly, to compensate for wear and renew performance. The enclosed type

impeller cannot be adjusted. Performance renewal requires new or repaired casing and impeller.

Minimum Hydraulic Loads

Extended Seal and Bearing Life

Goulds open impeller is engineered to assure minimum radial and axial thrust loads; controlled clearances

between front and back of impeller minimize radial loads; back pump-out vanes control and reduce axial

thrust. Bearing life is guaranteed.

Engineered For Long Life

Back vane height/angle and shroud design are engineered to minimize hydraulic loads throughout the

life of the pump. Bearing life is guaranteed. As the open impeller is adjusted and performance renewed,

back pump-out vanes control axial thrust. Bearing and seal life are maintained — unaffected by adjustment.

Sealing Flexibilty                                                                                                    

Extend Seal Life And Lower Maintenance Costs

SEAL ENVIRONMENT IS CRITICAL FOR EXTENDED SEAL LIFE

The number one cause of pump downtime is failure of the shaft seal. These failures are normally the result of an unfavourable seal environment such as improper heat dissipation (cooling), poor lubrication of the seal faces, or seals operating in liquids containing solids, air or vapors.

Goulds engineered seal chambers are designed to provide the best seal environment for any sealing arrangement.
Enlarged bore seal chambers (BigBoreTM and patented TaperBoreTM PLUS) with increased radial clearance between the mechanical seal and seal chamber provide better circulation of liquid to and from seal faces. Improved lubrication and heat removal extend seal life and pump uptime.

The bottom line is lower maintenance costs.

How It Works                                

The unique flow path created by the patented Vane Particle Ejector directs solids away from the mechanical

seal, not towards the seal as with other tapered bore designs, and the amount of solids entering the bore

is minimized. Air and vapours are also efficiently removed.

On services with or without solids, air or vapours, Gouldspatented TaperBoreTM PLUS is the effective solution

for extended seal and pump life and lower maintenance costs.

 • Solids/liquid mixture flows toward mechanical seal /seal chamber.

 • Turbulent zone. Some solids continue to flow toward shaft. Other solids are forced back out by

    centrifugal force (generated by back pump-out vanes).

 • Clear liquid continues to move toward mechanical seal faces. Solids, air, vapours flow away from seal.

 • Low pressure zone created by Vane Particle Ejector. Solids, air, vapour liquid mixture exit seal chamber bore.

 • Flow in patented TaperBoreTM PLUS seal chamber assures efficient heat removal (cooling) and lubrication.

   Seal face heat is dissipated. Seal faces are continuously flushed with clean liquid.

Goulds Dynamic Seal

Eliminate Sealing Problems, Reduce Maintenance Costs

On tough pumping services, especially corrosives and slurries, mechanical seals

require outside flush and constant, costly attention. Even then, seal failures

are common, resulting in downtime.

Goulds offers a solution: The Dynamic Seal which, simply by fitting a repeller

between the stuffing box cover and impeller, eliminates the need for a

mechanical seal.

Seal Flush Plans

All ANSI B73.1 seal flush and cooling plans are available to control emission levels and meet seal

installation requirements. Goulds can also provide other special arrangements of user preference.

Sealess Solutions

Not all process pump applications can be sealed with optimum reliability. Goulds ANSI dimensional

magnetic drive sealless process pumps are perfect solutions to mechanical seal or environmental

sealing problems. The 3296 EZMAG metal magnetic drive process pump has a revolutionary bearing

cartridge design for maximum reliability and ease of maintenance. For tough corrosive services Goulds

also offers ETFE® and PFA-lined magnetic drives available in horizontal, vertical or selfpriming
configurations to meet all your process needs.

CONTINUOUS PERFORMANCE

Original flow, pressure and efficiency are maintained by simple external adjustment resulting in long-term energy and repair parts savings.

Condition Monitoring                                                       

The heart of the i-FRAME the condition monitor unit continuously

measures vibration nd temperature at the thrust bearing and

automatically indicates when pre-set levels of vibration and temperature

have been exceeded, so that changes to the process or machine can

be made before failure occurs.

A visual indication of pump health makes walk-around inspections more efficient and accurate. The result is a more robust process to monitor

and maintain all your ANSI pumps so that your plant profitability is

maximized.

A reliability program centered around walk-arounds

captures equipment condition on average once a

month; the failure process, however, can begin and

end quite frequently within this time period.

Inbro VBXX-D Hybrid Labyrinth Seals                                                   

Inpro VBXX-D Hybrid Bearing Isolators

Most bearings fail before reaching their potential life. They fail for a variety of reasons, including contamination

of the lubricant. INPRO VBXX-D has long been considered the industry standard in bearing lubricant protection.

The i-FRAME now improves upon that design by offering stainless steel rotors,

for maximum protection against contaminants and the corrosive effects of seal

leakage or environmental conditions. These seals are non-contacting and do

not wear..

Optimized Oil Sump Design                                                                           

Internal sump geometry is optimized for longer bearing life. Sump size increased by

10%-20% results in better heat transfer and cooler bearings. Contoured design

directs contaminants away from bearings, to the magnetic drain plug for safe removal.

Increased oil capacity provides better heat transfer for reduced oil temperature.

Bearings run cooler and last longer. Contaminants directed away from bearings

to magnetic drain plug.

Premium Severe-Duty Thrust Bearings                                                 

Increase bearing fatigue life by 2-5X that of conventional bearing steels.

Every model 3196 Power End is engineered and manufactured for optimal pump performance

and increased MTBF.

The rugged shaft and bearing combination maintains shaft deflection of less than 0.002 inches at all

operating points. The result is longer seal and bearing life.

Premium severe-duty thrust bearings increase bearing fatigue life by 2-5X.

• High purity steels have fewer inclusions than standard steel — better grain structure and wear resistance.

• Heat treatment of bearing elements increases hardness for increased fatigue life.

Forty-degree contact angle on the MTi thrust bearing for higher thrust load capability.

• 35% higher dynamic load rating vs major competitor.

• Increases L'10 bearing life 2X.

LTi Power End for High Load Applications                                         

Increased L'10 Bearing Life 150% to 200% on the Toughest Applications

Ideal for tough conditions when a power end is pushed beyond ANSI limits: operating at low flows

and higher heads, pumping high specific gravity liquids, fluctuating process conditions, overhung

belt drive.

Oversized shaft and bearing assembly significantly expands the limits for long, trouble-free bearing and

seal life. On high load applications, the LTi power end improves bearing life 150%–200%; oil operating

temperature reduced by 45°F (25°C).
