Chopper pumps are designed to chop and macerate solids in wastewater applications including mop heads, pantyhose, wood, bottles, metal cans, and other solids larger than three inches.

Our best selling chopper pump is the Deming Demersible from Crane Pumps and Systems, which provides superior solid size reduction, high reliability, ease of servicing, and low life cycle costs.

The open center cutter design and hydraulics prevent solid build up around the pump and in the volute and impeller passageways, allowing the chopped solids to pass without any clogging.

The slicing blade and striker plate made from heat treated 440C stainless steel maintain their sharpness over and retain excellent solid size reduction capability. Plus, the blades last for a minimum of seven to eight years, minimizing the need for replacement. All wear items, including striker plate, slicing blade, bearings, and mechanical seals can be replaced in less than 30 minutes, saving you and your customer time and money. Its Plug-n-Play quick disconnect cord and large lifting ball make it easy to remove and service the pump from the pit.

An element that makes this product unique is its envie³ motor, with the platform's ability to continuously run in air meaning that its minimum required submergence is significantly lower than the competitions. This allows you to set floats lower, resulting in more regular turnover of the lift station, less FOG buildup, and less chance for the station going septic.

The envie³ high efficiency air-filled motor comes without application limitations. Its patent pending, closed loop glycol cooling system keeps motors stress-free, even in the most demanding applications, including shallow wells, high water tables, and rocky terrain. To maximize flexibility, the envie³’s air-filled motor option is available in both vertical and horizontal configurations. This premium efficient IE3 motor delivers significant energy savings and is easy to service.

Deming Demersible chopper pumps are available in standard and explosion proof models in 3-, 4-, 6-, 8- and 10-inch discharge sizes ranging from 3 to 150 hp with flows up to 5,000 gpm.

The Deming Demersible is ideal for demanding applications including trailer parks, hospitals, prisons, retirement communities, daycare centers, truck stops, mixed-use buildings, and RV parks.
