ANSI Process Pump 3196 i-FRAME Proven Performance
When the Goulds 3196 ANSI Standard Dimension Process Pump was first introduced in 1961, it immediately became the standard for the industry. Today, the number of installations attest to its remarkable performance. Users in chemical, petrochemical, pulp & paper, primary metals, food & beverage and general industries know they can make no better choice than the best — Goulds Model 3196.
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.
FULLY OPEN IMPELLER
Best design for the Chemical Process Industries services. Ideally suited for corrosives and abrasives, handles solids and stringy fibers with ease. Allows for simple restoration of clearances when wear takes place. Back pump-out vanes reduce pressure on the shaft seal, reduce axial thrust on the bearings.
ENGINEERED SEAL CHAMBERS
BigBore™ and TaperBore™ PLUS seal chambers allow seals to run cooler with better face lubrication. Keep solids, air and vapors away from the seal faces for extended seal life.
i-FRAME ® POWER ENDS
Patented design maximizes reliability and Mean Time Between Failure (MTBF). Severe-duty bearings increase bearing life 2-5 times, while onboard condition monitor gives visible indication of general pump health. Backed by a five-year standard warranty.
PUMP MOUNTING SYSTEM
Critical for reliability ... rigid baseplate prevents distortion, maintaining pump/motor alignment; corrosion resistant in severe environments. Designed for low vibration and to withstand pipe loads. Meets total range of plant requirements, easier installation and maintenance.
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.
Impeller
Must be designed for long-term, maintainable performance and minimum hydraulic loads for maximum reliability.
Seal Chamber
Must be designed for favorable 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 vapors.
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.
Baseplate
Must be rigid, and able to withstand forces and moments of plant piping systems.
Acknowledged Best Design for CPI Services
The open impeller is the acknowledged best design for process services. It is ideally suited for corrosive/erosive liquids containing solids and stringy materials. The most reliable pumps feature open impellers as standard.
See The Difference
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:
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.
Open Impeller
Wear is uniform throughout larger area; no concentrated wear... extended life, reduced repair part cost.
Enclosed Type Impeller
Less wear area with concentrated wear at nose of impeller … higher repair part cost.
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.
Open Impeller
Original performance can be re-set (at the bench or on-site) with external impeller adjustment using a common open-end wrench and feeler gauge. It is done in a matter of minutes.
Enclosed Type Impeller
Front nose ring of impeller cannot be adjusted to provide ‘as new’ performance. Parts must be replaced or repaired.
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.
Back Pump-Out Vanes Goulds Engineered Seal Chambers
The number one cause of pump downtime is failure of the shaft seal. These failures are normally the result of an unfavorable 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 (BigBore™ and TaperBore ®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.
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 Pumps 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. Benefits of Dynamic Seal: • Eliminate use of seal water • Eliminate pumpage contamination and product dilution • Reduce utility cost • Eliminate problems associated with piping from a remote source • Eliminate need to treat seal water • Considerably less expensive than a slurry mechanical seal
Besides being available as a complete unit, any Goulds 3196 can be easily field-converted to Dynamic Seal. Retrofit kits are available.
Sealless 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 self-priming configurations to meet all your process needs.
The unique flow path created by the 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 vapors are also efficiently removed. On services with or without solids, air or vapors, Goulds Pumps TaperBore ® PLUS is the effective solution for extended seal and pump life and lower maintenance costs.
Goulds i-FRAME Power Ends are the result of 160 years of design experience, customer interaction, and continuous improvement. Customers get extended Mean Time Between Failure (MTBF) and lower life cycle costs (LCC) ... guaranteed!
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.
