Cleaning Carbon Tanks In Carbon in Leach And Carbon in Pulp Processes

Christian LindBlog, Service Adventurer, Tech TalkLeave a Comment

The two gold extraction processes CIL (Carbon in Leach) and CIP (Carbon in Pulp) are quite similar, both using granulated activated carbon to extract the gold from the solution. For the extraction processes to function efficiently a specific carbon granule size must be maintained.  It is therefore critical to handle the fragile carbon particles in a manner that does not … Read More

Understanding How Static And Dynamic Balancing Affect Cantilever Pumps

Christian LindBlog, Service Adventurer, Tech TalkLeave a Comment

I was recently asked to investigate a vibration in a vertical cantilever pump. The client had recently rebuilt the pump and was wondering what he had missed or done wrong. In the absence of any vibration monitoring equipment, we resorted to physical checks. With the pump out of the sump, we carefully rotated the shaft and there was no evidence … Read More

What exactly is an impeller’s “tip speed” and how do you calculate it?

Christian LindBlog, Service Adventurer, Tech TalkLeave a Comment

Establishing an impeller’s “Tip Speed” is very useful when selecting the best pump for your application, but what exactly is tip speed and how do you calculate it? The tip speed is simply the distance that any selected point on the peripheral of the impeller travels in a set time. In other words the “speed” of that point. To calculate … Read More

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
