Peristaltic pump type GZ and LZ 50

• Suitable for permanent operation

• Closed system, no contamination with conveyed material

• Low maintenance

• Pumping of higher viscosity media possible

Due to their completely closed system, the GZ and LZ 50 peristaltic pumps are ideally suited for use with weir skimmers in oil damage control. Contamination of the pumped medium with the mechanical parts is not possible in this design.

The peristaltic pump (also known as hose squeeze pump, roller pump or peristaltic pump) is a strongly self-priming positive displacement pump that works according to the peristaltic delivery principle. In the process, the pump hose is alternately compressed, i.e. closed, and released again by three rotating rolling bodies inside. When the hose returns to its original shape, the previously created vacuum creates suction and draws in the material to be conveyed. The rotation of the rollers conveys the medium further.

The complete pump system is mounted in a frame and equipped with an Ex variable speed gear motor.
