A large paper mill in Sydney required a reliable solids handling pump capable of transferring pulp waste slurry with high concentrations of suspended solids such as cardboard, strapping, etc. The solution offered was a Vaughan model SP8N self-priming chopper pump direct coupled to a 55 kW, 6-pole speed electric motor. As a result of this pump's success, additional Vaughan self-priming pumps have been supplied for various other critical applications at the plant.
