3P Prinz brochure - .PDF file.

Michael Smith Engineers has introduced a range of hollow rotary disk pumps designed to operate at low speeds and to handle more challenging liquids such as those with suspended solids or higher viscosities (up to 200,000cSt). According to the company, the 3P Prinz low-speed rotary positive displacement pumps are suitable for fluids-handling applications in the chemical, petrochemical, oil and gas, food and beverage, pulp and paper, marine and shipbuilding industries or wherever the low-speed pumping of challenging liquids is required.

With multiple porting and seal options, the 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 the 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 designed to ensure high hydraulic efficiency, which means smaller motors are required along with lower running costs compared with other types of positive displacement pumps. They have limited dry-running potential, which can prevent expensive pump failure in the event of system upsets.
