Moving wastewater efficiently often requires the use of specialized pumps equipped to handle solids and prevent clogging. Chopper and grinder pumps are designed for this purpose, utilizing robust cutting mechanisms to macerate rags, debris and other challenging materials into a manageable slurry. Some designs employ multiple cutting stages to ensure even fibrous materials are processed effectively. Features like self-priming capabilities and external mounting options simplify maintenance and minimize downtime. Advanced grinder designs with monolithic rotors offer increased durability and reduced maintenance needs compared to traditional multi-blade systems. Check out some product options below.
Vaughan Chopper Pump
Self-priming Chopper Pumps from Vaughan are designed to be easily accessed outside of the wet well while pumping waste solids at heavy consistencies without plugging or dewatering of the solids. They eliminate the loss in production and mess along with making it easy to service the pump to get it back in operation. 888-249-2467; www.chopperpumps.com
Ashland Pump AGP-HC200 Grinder Pump
The AGP-HC200 Grinder Pump from Ashland Pump combines two cutting mechanisms to tackle waste. Its radial section efficiently grinds waste into a fine slurry, while the axial section excels at cutting and chopping stringy solids and waste into smaller, more manageable pieces. This dual-action approach ensures that even fibrous materials are easily processed and do not cause clogs in the discharge pipe. Moreover, its cutters are engineered to prevent wrapping at the inlet, a common issue with grinder pumps. Crafted from case-hardened 440 stainless steel, these cutters are not only durable, but also easy to sharpen and adjust for optimal performance. 855-281-6830; www.ashlandpump.com
Vogelsang XRipper
Vogelsang’s XRipper twin-shaft grinders are designed to protect pumps and process equipment in wastewater applications. Their defining design element are their Monolithic Ripper rotors — one-piece cutting elements that are a significant improvement from traditional grinders with individual blades and spacers. Wipes, rags, plastics, sanitary items and other debris that sneak past screening systems can easily clog pumps and disrupt the treatment process. Grinders with “spacer” designs are prone to issues as they wear down and require labor-intensive maintenance. Ripper Rotors are robust enough to hold up over time and are easy to service when needed. They come in several models for pipeline and channel applications and numerous sizes to suit all standard dimensions and output requirements. They are also available as a drop-in replacement, allowing users to upgrade from old units easily. 800-984-9400; www.vogelsang.info/
