Differences Between Flush and Quench In Slurry Pump Seal Support Plans

Christian LindBlog, Service Adventurer, Tech TalkLeave a Comment

When discussing slurry pump seal support plans it seems that the terms “Flush” and “Quench” are often confused and or misused. With the concept being slightly different for mechanical seal boxes vs packed seal boxes I will separate these, discussing each in turn. Mechanical Seal The basic mechanical seal flush plan is very simple. It calls for a clear/clean liquid, … Read More

No Flow Meter, No Problem

Christian LindTech TalkLeave a Comment

The Open Pipe Flow Measurement Method Over the years our team has been involved in countless pump start ups, many of which were field applications where instrumentation was non existent.  There is always an expectation of a specific flow rate or at least a minimum flow rate. Without a flow meter, how do you know if your pump is performing with … Read More

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
