Vaughan is a company with a long experience in grinder pumps. Jim Vaughan, founder of the company, first invented the grinder pump in 1960. It was designed to reduce problems of clogging, blockages and constant maintenance in the pumping of cattle slurry with high straw content. It subsequently used the grinder pump in other sectors with similar clogging problems, both in municipal water and in industry. In 1960 the first patent was issued and since then more than 40 patents have been issued worldwide, aiming to improve pump efficiency and reliability in extreme applications. With over 20,000 units in service, the Vaughan grinder pump has not only proven its value in problem solving but has also proven to be a reliable alternative to other conventional pumping.

Vertical wet well pump
Advantages
- Characteristics: up to 1800 m3/h, up to 55 mca.
- 7 assemblies available: vertical wet well, submersible, horizontal, vertical dry well, self-priming, vertical-recirculating, submersible-recirculating.
- 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.
- Possibility of dry turning, for HE series.
- 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.
