While GIW Industries, Inc.’s pumps help our customers succeed every day, some materials can break down over time — either from misuse or from contact with abrasive or corrosive materials. One customer recently experienced a leak that resulted from a worn shaft sleeve. Here’s..Read More
Q: Can I reduce pump wear if I install a larger pump?
A: The simple answer is probably not. You can actually increase pump wear if your pump is too large for your particular application.
"This answer seems counterintuitive to many people when they hear it," notes Reab Berry,..Read More
Each day, GIW Industries, Inc., engineers work with our customers to solve problems associated with their pumps. One pump component we get a lot of questions about is the cartridge bearing assembly. We spoke to Jon Keith, GIW Product Manager, about three problems faced by..Read More
The pump performance chart above is a graphical representation of performance for a particular pump. By using this chart, you can see the head, or pressure, that the pump produces at various flow rates and at different speeds. For example, at 560 RPM, the pump will produce..Read More
On a GIW Industries, Inc., LSA or similar pump, a special gasket seals the joint between the suction liner and the pump casing. This gasket is a variation of a simple O-ring gasket, except it has a cross-sectional shape of a trapezoid. The exclusive design provides an..Read More
One pump operator recently came to GIW Industries, Inc., with a startling but not unique problem: Slurry was leaking from the back of his stuffing box. We reached out to Technical Services Manager Kenny Meyer about stuffing box malfunctions, some potential consequences, and..Read More
When it comes to extracting materials from a slurry, the method of extraction can have as many consequences as it does advantages. In some processes, air is injected into the slurry, which separates the desired materials (such as ore) from the discardable liquid. Froth..Read More
When it comes to efficient slurry pumping, understanding how the solids within a slurry behave is very important. Depending on the particle size, distribution, concentration, and character of solids, the slurry can be either “settling” or “non-settling.” Non-settling..Read More
If you’re an experienced slurry pump operator, you’re aware of some of the reasons for high rates of pump wear — which can negatively affect pump performance over time. Although slurry characteristics such as particle size and concentration may first come to mind, an..Read More
If you own or have ever seen an older pump’s bearing assembly, you’re probably familiar with the old oil breather. If this is the case, you may be surprised or confused when you see a GIW® Minerals pump that doesn’t have one.
That’s because GIW bearing assemblies no longer..Read More
