Hollow rotary disk pumps

The 3P Prinz low speed rotary, positive displacement pumps are suitable for transferring sensitive liquids at flow rates to 250 m3/hr. They operate at discharge pressures up to 8 Bar as standard; high pressures versions can be specified for discharge pressures to 20 Bar.

They are available in a choice of wetted materials including cast iron, bronze and stainless steel to ensure broad chemical capability, extended pump life and longer service intervals.

With multiple porting and seal options, these versatile pumps are self-priming and, in addition to coping with liquids containing suspended solids, they provide low-pulsing, accurate output. The self-priming design with high suction lift capability simplifies installation on-site, while modular construction ensures simple maintenance operations without the need to disconnect the pump from piping.

The elasticity of the disc also allows for thermal expansion and passage of solid particles in the liquid. The pumps are also designed for high hydraulic efficiency which means smaller motors are required along with lower running costs. They have limited dry-running potential which can prevent expensive pump failure in the event of system upsets.

3P Prinz pumps are suited to a wide range of fluids handling applications in the chemical, petrochemical, oil & gas, food & beverage, pulp & paper, marine & shipbuilding industries or wherever effective and reliable, low-speed pumping of challenging liquids is required.
