Challenges of Dewatering: Will adding another pump to my system help?
Recently I was asked for support at an open pit mine that was having trouble dewatering. The main challenge in short was that the inflow from springs and rainfall was exceeding their capacity to pump water from the pit floor and this was affecting mining operations. The first step was to tour the mine to get an overview of the … Read More
No Flow Meter, No Problem
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?
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?
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
Beat the Rush
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
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
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
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
Gain In-Depth Knowledge on Cavitation
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
