The GPM Eliminator - Why choose a heavy-weight, oversized pump.

The GPM-Eliminator is Made Tough™—and the competition doesn't stand a chance against our pump’s durability. Our meticulous engineering created an intentionally oversized pump that eliminates many common pump failures. 

                 Figure 1

Figure 1 shows a component-by-component weight comparison of the GPM-Eliminator and a competitor pump brand. Both pumps are Submersible 20-hp pumps, but one of them is clearly the pump heavyweight champion. The GPM-Eliminator is 58% heavier than the competition, but why is that important to factor in when looking to purchase an industrial pump built to handle abrasive slurry?

Our heavyweight design is critical for solids handling, offering solutions to common issues that cause pump failure, such as shaft deflection and excessive wear. With the help of robust metallurgy and engineering, our pumps deliver massive cost savings on maintenance and repair. 

Several key factors make the GPM-Eliminator stand out among the industry’s top pumps.

Heavy-Duty Impellers

The GPM-Eliminator’s impeller is designed for extreme durability in abrasive environments. Available in a variety of metallurgies ranging from 28% high-chrome iron with 650+ Brinell hardness to CD4MCu, we designed our impellers with thick, oversized vanes that resist wear and withstand the harsh impact of abrasive slurry or chemical compounds.

Oversized Shafts

Most pump issues can be traced to seal or bearing failures, often caused by shaft deflection. Excessive shaft deflection subjects these critical parts to unusual stresses. Mechanical seals with 0.0000232” – 0.000348” tolerances are particularly vulnerable to shaft deflection and vibration, causing costly repairs and pump replacements after fluids enter the oil chamber and motor housing.

The GPM-Eliminator’s oversized 416 stainless steel shaft is designed to endure the demands of slurry pumping and reducing eccentric rotation. Figure 3 highlights the noticeable difference between oversized and standard shaft thickness on bearings and other critical components. Opting for a pump with an oversized shaft is a strategic choice to enhance reliability and extend the pump’s lifetime. 

Formidable Casing

The GPM-Eliminator’s wet-end casing options use a robust metallurgy comprised of 28% high-chrome iron with a formidable 650+ Brinell hardness. We leveraged the added strength of these materials to resist wear and ensure an extended operational lifespan.

If your pumps keep failing, consider upgrading to the GPM-Eliminator, the true pump heavyweight champion.
