Self-priming pump

Self-priming pump

The self-priming grinder pump assembly is unique and exclusive to Vaughan. There are other brands that have self-priming pumps, but they are solids-passing.

Available from 4″ or 6″ or 8″ or up to 10″.

The motor is standard with B35 IEC flange.

The exclusive design of the body allows us to externally adjust the tolerances of the impeller with the shear plate, at the suction side, without disassembling the pump.

We have mounted it as a transfer pump, mixing pump and, above all, on the desanding cart, to replace the traditional vertical pump system. Our solution allows us to facilitate assembly, improve maintenance and eliminate clogging and the use of cranes.

Advantages

  • 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 cutter plate.
  • Oversized shafts and bearings.
  • Various materials: ductile iron, stainless steel 316 or duplex CD4MCU.
  • 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.
  • We shred solids such as: rags, fibers, plastics, hair, cellulose, etc.
  • Vaughan’s written guarantee is its commitment to performance, that its pumps will crush solids without clogging.
