Spotlight on: Zoeller Grinder Pumps
Watch the Zoeller Grinder Pump, aka the world’s first integral automatic grinder, in action as it grinds and pumps three non-flushable items in mere seconds!
Conney Brothers' Tom Rafferty and Burns Cope Associates Gene Sung demonstrate the “grind” feature of the Zoeller M807 Grinder Pump and puts it to the test using a glove with a maxi pad and tampon inside. While any of one these items would normally clog the typical sewage pump, especially when flushed together, the 807's robust cutting mechanism grinds these items up with ease before quickly pumping them out in the form of fine, shredded particles.
Zoeller's triple-blade technology and exceptionally durable design ensures that these pumps can handle larger solids than any other wastewater pump on the market. Perfect for specialized applications that require extra operating power, Zoeller Grinder Pumps deliver grinder technology to residential and light commercial users without the commercial costs!

What Are Grinder Pumps?
The Zoeller Grinder Pump is one of the most durable wastewater solutions in the industry. As a go-to for users of all kinds, this pump works especially well with complex systems that require the additional strength. Our video above highlights the key feature that truly sets it apart from the rest: it doesn’t just pump—it grinds!
Equipped with Tri-Slice® cutter technology, Zoeller’s grinder pumps have the power to shred solid waste into 1/8” particles and form a fine slurry for the pump to suck up through small inlet holes. The stainless steel rotating cutter guarantees liquids and solids handling up to 2” in size, providing grinder pumps with a robust advantage over standard wastewater pumps who generally cannot handle larger solids.
Thanks to this industry-proven cutting mechanism and greater operating power, the Zoeller Shark Series® Grinder Pump’s patented technology delivers a top-of-the-line performance in demanding applications where ejectors tend to struggle. These features make grinder pumps the perfect choice for applications that:
- Experience clogs
- Have narrow, small-diameter lines
- Require extra strength/pressure to pump uphill, over long distances, or into pressurized sewer systems

Versatile specifications and user flexibility are common in Zoeller pumping products, but they’re especially critical for grinder pumps—the only wastewater pumps qualified for specialized applications. One of the most used Zoeller grinder pumps for users working specifically with pressure sewer systems is the Zoeller 840 2 HP Grinder Pump, the industry’s only auto-reversing impeller and cutter assembly with the power to double the service life of the typical grinder.
Now that we have a fuller picture on grinder pumps, it should be a little easier to identify what sets them apart from other wastewater pumps. Even though sump/effluent, sewage, and grinder pumps are all well suited for various residential and commercial applications, their pumping capabilities are quite different from one another. This means that each of these three wastewater pump types will best perform in their own unique applications and working conditions.
In Short:
Sump Pumps and Effluent Pumps – Remove and manage unwanted water in residential and commercial applications
Sewage Pumps – Remove sewage and manage wastewater in traditional residential, commercial, and some industrial applications
Grinder Pumps – Grind waste, remove sewage, and manage wastewater in specialized residential, commercial, and municipal application
Sump and effluent pumps are very closely related because of their ability to filter out most solids prior to pumping. Although, since sump and effluent pumps can only handle minimal solids, they do not have as much overlap with sewage and grinder pumps who do have solid waste pumping capabilities.
However, that is where the overlap ends with sewage and grinder pumps. Sewage pumps act as the go-to for average sewage and wastewater systems while grinder pumps are an absolute must for specialized systems because of their cutting feature, higher head pressure and larger solids handling. These capabilities provide grinder pumps with the extra strength that is needed for unique applications like when waste must travel upwards without the help of gravity, over long distances, or into pressurized systems.
