The GPM-Eliminator™ submersible slurry pump is engineered for uncompromising reliability. Proudly made in the USA, it features built-in casing spray holes for effective sump agitation, Class-H motor insulation with run-dry capability, and a robust mechanical seal design that prevents water ingress—eliminating a leading cause of premature bearing and motor failure. The result is an industrial-grade slurry pump that significantly reduces maintenance costs and extends service life.
All parts, components, and castings are sourced in the USA, and the GPM-Eliminator is manufactured in Duluth, Minnesota.
No additional water source is required; the spray holes use the pump casing’s pressure and flow to direct water back into the slurry mixture for agitation.
Submersible motors are Class-H TENV inverter-duty motors with run-dry capabilities, capable of handling sump temperatures up to 180°F.
Our submersible slurry pumps are designed for extreme abrasive slurry applications and can handle everything from dirty water to 70% solids.
Oversized shaft and bearing design prevent shaft deflection, extending seal and bearing life when handling abrasive solids.
The GPM-Eliminator has an innovative mechanical seal configuration that outlasts competing brands. With three way to protect and extend life.
The GPM Eliminator is designed to handle large solids — up to 4.5 inches (≈115 mm) in diameter — in its standard heavy-duty wet-end configuration. Additionally, it can handle slurries of up to 70% solids by volume in some configurations.
Yes. The GPM‑Eliminator’s submersible slurry pump is explicitly engineered to run dry for extended periods without catastrophic failure — a key differentiator. It uses a Class-H insulated motor winding and an inverter-duty motor design for durability.
No, the GPM-Eliminator is equipped with built-in wet-end spray holes that require no external water source. The spray holes use pressure and flow from the pump casing to direct water back into the slurry mixture for agitation. The unique spray hole technology keeps solids suspended, eliminating solids buildup in the sump.
Yes, the GPM-Eliminator industrial submersible slurry pump is manufactured in the USA, right in Duluth, MN. We source all of our parts, components, and castings in the USA.

To size a GPM-Eliminator submersible pump for any application, the GPM team can come on-site to take the following measurements:
The GPM-Eliminator Low-Head (LH) liquid-end style is the best option for heavy slurry. Rated to handle up to 70% solids slurry mixtures with built-in casing spray holes to help keep solids suspended. The LH liquid end is a semi-open impeller composed of 28% high-chrome iron, with a 650+ Brinell hardness. Stainless steel options are available upon request.
All GPM-Eliminator wet-end configurations are engineered to handle high solids pumping applications. They key? Large semi-open impeller vanes to handle extended wear and allow solids passing through the pump.
Typically, when a pump is experiencing premature wear, it is running outside its best efficiency point. That said, different wear patterns can be observed when the submersible pump is not sized adequately for the application or is continuously operated outside of the best-efficiency point.
Pumps being run back on the curve can result in the following:
Pumps being run out on the curve can result in the following:
The GPM-Eliminator’s built-in spray holes often agitate solids sufficiently, but for very heavy, high-solids sumps, GPM offers standard mechanical agitators and spray rings as accessories. The spray ring accessory does require an external water source, which GPM can help specify for your applications.
Yes, with GPM’s standardized taper shaft design, all liquid ends are interchangeable. Making for easy replacements or wet-end changes due to sump and production changes.
There is virtually no maintenance on the GPM-Eliminator. You can check the seal oil annually if time allows, though it is not necessary. The advantage of the pump is that it is set it and forget it.
We stock an extensive inventory of parts covering every component of our standard pumps, along with a wide selection of fully built pumps ready for immediate delivery to your site.
GPM-Eliminator pumps are intentionally overbuilt to withstand abusive applications, featuring an oversized shaft, Class H insulation rated for dry running, and a self-agitating design that prevents silt buildup in the sump. The key differentiator is a simple, robust mechanical seal that enhances reliability and extends pump life by keeping pressure and solids away from the seal faces.
