ChopX Chopper Pump
ChopX Chopper Pump
ChopX Series Chopper Pumps perform the dual function of cutting and pumping, making them ideally suited for applications requiring reduction of solids size and/or protection of downstream equipment.
PRINCIPLE OF OPERATION
Hayward Gordon's ChopX Chopper Pumps design is an open-type impeller with sharpened leading and vane edges. The primary chopping and conditioning action of solids within the fluid is provided by the impeller's leading edges rotating in tight clearance across the cutter bar at the pump suction. A secondary cutting and expulsion action takes place behind the impeller with the impeller's sharpened vane edges, which rotate across spiral grooves on the backplate. This secondary cutting action both cuts and expels solids from behind the impeller.

Benefits
Dual Function - Pumping & Chopping
ChopX pumps provide both cutting and pumping action in a single unit. This saves maintenance and capital cost associated with purchasing separate solid grinders and comminutors
High Efficiency
Our patented, computer generated impeller blade profiles provide cutting action at the leading edge while ensuring a smooth flow path for the fluid along the rest of the vane. The smooth flow minimizes turbulence, thereby reducing power consumption and improving NPSH.
Protection from Internal Binding & Fouling
After chopped solids enter the pump, they are prevented from binding the impeller or fouling the seal area by a secondary cutting and clearing action.
The impeller’s sharpened vane edges rotate over spiral grooves in the back plate. The interaction of the impeller vanes and grooves acts to cut and then expel stray solids from behind the impeller.
Abrasion & Corrosion Resistant Construction
Hayward Gordon manufactures the ChopX pumps for heavy duty service and increased longevity when pumping corrosive or abrasive slurries.
The ChopX pump components can be manufactured from Ni-Hard, High Chrome, Hardened Alloy Steels and Stainless Steels.
