Horizontal pump

• 7 cut-off points, patented and/or patent pending.
• Manufacture of the pump with numerical control equipment allows the automated repetition of the parts and eliminates any defects in its construction.
• Hardened materials up to 600 Brinell, withstand abrasion and facilitate the crushing of solids.
• External adjustment of the tolerance between the cutter bar and the impeller on the suction side. There is also the possibility of adjusting the tolerance between the impeller and the rear upper cutting plate.

Oversized shafts and bearings.
Various materials: ductile iron, 316 stainless steel or CD4MCU duplex.
Modeling of the parts in 3D and using Computational Fluid Dynamics or CFD/CFX, allows to see the flow channels and velocities inside the pump, to develop design improvements and increase efficiencies.
Crushes solids such as: rags, fibers, plastics, hairs, cellulose, etc.
Vaughan’s written guarantee is their performance commitment that their pumps will grind solids without clogging.
