Keeping Temperature in Check in Centrifugal Pumps – Part 1
As discussed in the February article on Low Flow Concerns in Centrifugal Pumps, one of the motives for establishing a minimum continuous safe flow rate (commonly abbreviated as MCSF) is temperature rise in the fluid. There are several causes of efficiency losses in...
New Super-Sized ANSI Chemical Pumps
AVS. ANSI. ASME. In the pump world, these terms refer to one of the most commonly applied pump specifications recognized worldwide. The abbreviations may have evolved over time, but the core features have remained constant: end suction overhung rotor, back pull-out...
Sales Managers Meeting #1 of 2014
With the throwing of the first pitch and the approach of hockey playoffs, Wilfley saw an opportune time to hold the first of its four No Travel Weeks of 2014 for the Sales Managers. No Travel Weeks happen on a quarterly basis and give the Sales Managers the chance to...
Froth-handling and Wilfley Side Suction Slurry Pumps
The mere mention of “froth-handling” sends chills up the spines of many rotating equipment engineers. Indeed, froth and entrained-air handling in centrifugal pumps is a complex subject, which sources such as the Hydraulic Institute even admit that “…it is practically...
Prototype Static Seal Installed in AF Chemical Pump
Wilfley recently updated a long-running AF chemical pump with a brand new prototype static seal. The pump has been operating successfully in a very tough ammonium nitrate service for over 20 years. To ensure reliable seal operation, AF pumps require normal...
ASME B73.1 and ISO 5199 – A Quick Comparison
The widely referenced centrifugal pump standard known as ASME B73.1 can trace its origins as early as 1955, when efforts to develop chemical pump standards began. This later evolved into the American Voluntary Standard in 1962 and, in conjunction with a similar...
Low Flow Concerns in Centrifugal Pumps
Centrifugal pumps are kinetic devices that continuously impart energy to the fluid passing thru it, nominally designed around a desired flow and head point called the Best Efficiency Point (BEP). Since the BEP is a specific point, it is unlikely to find an application...
The DryLock® 2 Proves Itself in Difficult Filter Feed Application
Two years ago, a long-standing Wilfley client put forth newly established mandates that "No acid shall hit the ground” in their filter feed application. The client was using legacy Wilfley products that were outdated and the sealing technology could not live up to...
DryLock® Update Saves Time & Money
Wilfley has optimized its increasingly popular DryLock® 2 Static Seal, available for the extraordinary A9 and A7 Chemical Pumps. Working in concert with the efficient Opti-Expeller, the latest DryLock® 2 Static Seals further extend process uptime. The latest update...
The EMW® Slurry Pump Goes “Seal-less”
The superlative EMW® Slurry Pump, launched over a year ago, has demonstrated class leading efficiency and wear resistance in some of the most severe slurry applications in the field. Now, A.R. Wilfley & Sons, Inc. is pleased to announce the availability of a new...
Wilfley’s 2014 New Year’s Resolutions
Eat healthy? Lose weight? Drink less alcohol? Here at Wilfley we think more in terms of seal development, Quality initiatives, and metallurgy... Outside of more involved Goals and Objectives and continuing initiatives (that we can tell you about)... New heavy duty...
Wilfley is Looking for Test Sites for New Static Seals
The Wilfley engineering department is constantly developing new concepts and designs when it comes to statically sealing our pumps. This can be seen most recently with our highly successful and proven DryLock® 2 static seal (available for the A7 and A9 chemical...
