What is “Slurry” and why does it take a special pump to handle it?

The word “slurry” is used to describe a liquid with solids in suspension. This can be as light as chocolate milk (cocoa particles suspended in milk), or as heavy as concrete (sand, rocks, crushed limestone in water).

Pumps that are designed to handle slurries must be able to counteract the effect that solids in the material have on the equipment and systems in which they are used. If the solids are abrasive (think sand or crushed rock), the pumps must be constructed of materials that will resist the erosion that comes as a result of the impact of those particles have as they come into contact with the pump casing and impeller. Special hardened metal alloys, elastomer liners, or combinations of both are commonly used to effectively control these forces. The impellers are designed with wider vanes to handle over sized materials that are commonly found in processes such as hard rock mining, dredging, or pulp and paper.

Selection of pumps to handle slurries with settling solids must take into consideration the size, density, shape, and concentration of the solids along with the temperature and viscosity of the liquid in the mixture. If you take a gallon of water and add a cup of dry sand to it, the sand particles will quickly settle to the bottom of the container. If you are pumping a slurry containing sand, the material must maintain a velocity within the pump and the piping to maintain the particles in suspension or the pipe will quickly become clogged. Therefore, the heavier the solids—the faster they will settle and the higher the velocity required to keep the solids in solution.

These are just a couple of the details that are taken into consideration when selecting a slurry pump. Similar to the difference in jogging on pavement vs jogging on the beach, the effects of solids require special considerations and designs to counteract the changes brought about by the materials being pumped.

GIW Industries has been the rock on which I have built Hunter Equipment Company as the most complete slurry handling equipment supplier in the southern US, Jamaica, and Dominican Republic. GIW awarded HEC the contract to represent the finest and most technically advanced supplier of slurry pumps used in the transport of solids…Tagged by persons who have witnessed their work at their Grovetown, GA facility as an “Engineering Company that Builds Pumps”, their history and pioneering work in this special niche market lead the world in design and materials to handle the toughest mining and slurry markets. Visit their website for a quick tour of a different approach to manufacturing, engineering, and slurry research happening daily just outside beautiful Augusta, GA.  www.giwindustries.com

My heart and loyalty will always be with the company that gave a “lucky” young guy a chance to build his dream and have supported my company since April 1994..


Company Re-Branding!

Welcome to my first blog and first blog post on the newly renovated Hunter Equipment Company website. You will notice our original “HEC Swirl” logo/corporate image has been replaced with a fresh updated design that I am still getting used to.
After 18 years in business, it was time for a fresh new look and we are proud to introduce  it to you now.

Original since 1997

New and Improved!


The website redesign and Hunter Equipment Company’s new marketing partner Drift Web Design will be rolling out the www.hunterequipmentco.com
fully interactive new website in a couple of weeks. Please look for an upcoming kick off date when the new site will go live.
