What is the Difference Between Malleability and Ductility?

Christian LindTech TalkLeave a Comment

In the blog article, “Thermal Shock” I used the word ductility. This word is one of a handful of terms commonly used to describe the characteristics of metals and how they react to externally applied forces. Terms such as malleability, hardness, brittleness, toughness, abrasion resistant and impact resistant are commonly used when describing metals but not always completely understood. THE DIFFERENCE BETWEEN … Read More

How Do You Solve Vibration Issues in a Slurry Pump?

Christian LindPumps, Tech TalkLeave a Comment

Vibration issues with your slurry pump might be obvious: your slurry pump shakes like a wet dog, or subtle: you keep losing bearings or seals prematurely and don’t understand why. In either case, vibration can cause a number of problems with your pump that can lead to costly repairs, downtime, and shorter mean times between failure.  How to Confirm a … Read More

Thank you to everyone who sent in questions to info@hevvypumps.com. We have taken one of the top questions and answered it below! Frequently asked Question: Should we install a vfd to control our pump? Background Variable frequency drives, or VFDs, do pretty much what their name suggests. They drive electric motors at variable frequencies providing significantly more control than “On” … Read More

Thermal Shock

Christian LindTech TalkLeave a Comment

Our blog on “Total Discharge Recirculation” mentioned thermal shock as a destructive force that can damage or destroy pump components.  With how destructive this force can be, I thought it necessary to spend some time expanding upon this subject. What does thermal Shock mean in pumps? Wikipedia explains that thermal shock occurs when a thermal gradient causes different parts of an … Read More

Gain In-Depth Knowledge on Total Discharge Recirculation

Christian LindTech TalkLeave a Comment

In previous blogs we have defined Cavitation and reviewed Discharge Cavitation.  In this blog I would like to discuss a specific type of discharge recirculation known simply as “Total Discharge Recirculation” or “TDR” for short.  All forms of pump recirculation, as the term denotes, evolve some portion of the liquid not following the desired path.  When referencing total discharge recirculation, the difference is … Read More

Gain In-Depth Knowledge on Discharge Recirculation

Christian LindTech TalkLeave a Comment

In our last blog we discussed cavitation singling out suction cavitation to illustrate the concept. In this blog, as promised, we will discuss discharge recirculation, also sometimes referred to as discharge cavitation.  The term discharge recirculation is often used interchangeably with the term discharge cavitation.  Although these two are clearly related they have a few distinct differences.  Let us first examine discharge recirculation. … Read More

What it is and how it works Cavitation is potentially the most destructive force at play within a pumping system, however it is the least understood issue by many pump operators. To quote Sun Tsu from the Art of War, “know thy enemy”. In this blog, we will discuss our enemy cavitation and how it relates to pump cavitation. This article … Read More

Gain In-Depth Knowledge on NPSHA In this blog we will discuss Velocity Head as it is the final component left of our 6 part NPSHA blogs and the one we have avoided addressing previously. Reference books would describe velocity head as a basic concept of fluid engineering that represents the bulk motion, i.e. the kinetic energy, of the fluid. It can … Read More

How To Prime Your Industrial Slurry Pump?

Let’s get into priming your industrial pump Did the POTUS really coin this phrase and what does it mean? Today the President of the United States of America, Donald Trump, put the pump industry into the mainstream by claiming to have coined the phrase “priming the pump”.  In doing so he highlighted one of the basic principles of pumping and … Read More
