I often receive questions as to whether a check valve in a pumping system is a good or a bad thing. Auto closing check valves are often an integral part of a successful pumping system; however, they can also be the root of many system failures. The question then becomes “when is it appropriate to incorporate check valves in a … Read More
Single Phasing in Electric Motors
Causes and Solutions to Protect your Motor I once had a customer ask me for some advice to help them come up with some ideas as to why their pump would trip as soon as it was lowered into slurry. I asked questions such as: Have you checked for proper rotation? Did you check for pluggage in the discharge line? … Read More
Slurry Pumps: The Ultimate Preventive Maintenance Guide
Are your slurry pumps in good condition? I travel to customer sites on a weekly basis and I see a full range of good and bad when it comes to pump maintenance. I decided to write a blog on the most common preventive maintenance tips concerning the Hevvy/Toyo line of pumps so it’s available even when I’m not. This list … Read More
6 Pipeline Flow Issues and How to Avoid Them
One of a pump operator’s worst fears is a plugged pipeline. Some believe this to only be a concern when dealing with extremely heavy slurries but this is far from the truth. Today we will discuss several causes of plugged lines and how to avoid these highly expensive and time-consuming problems. 1. “Sanded in” Is the most common form of … Read More

Ghost in the Pump
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
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
Grease the Bearings
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?
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
