Ghost in the Pump

Christian LindService AdventurerLeave a Comment

Pumping Industry Solutions I received a call from a customer that one of our new pumps was acting up. The pump would quit pumping and then all of a sudden start again. They pulled the trouble pump out of service, replaced it with a spare, and asked me to come on site to perform an inspection. I arrived onsite and with the help of customer’s … 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

Grease the Bearings

Christian LindService AdventurerLeave a Comment

Put Bearing Misconceptions to Rest One of the most common failures that I encounter in my travels is customers often times do not grease the bearings in our vertical series of pumps. Because of this, most of our pump failures involve the lower bearing. Customers will often grease the upper bearings assuming the grease makes its way down to the lower bearing. This … Read More

What is the Number One Cause of Pump Motor Failure and How Can it be Prevented?

Christian LindPumpsLeave a Comment

According to our electrical team, heat is the number one cause of motor failure. It simply kills them. Temperatures near or above the insulation rating of your motor will cause your motor’s insulation to deteriorate faster, ultimately resulting in premature motor failure. Defining the starting limit for your pump’s electric motors  Our team is often asked one important question: How … 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
