Pomac rotary lobe pump
Flexible application options to assortment of rotors
The goal when developing the rotary lobe pumps from Pomac was maximum pump capacity at minimal impairment of the medium.
Along with the compact form of the construction, the volume between the rotary lobe pumps has also been optimized. This makes the rotary lobe pumps suitable for a high operating pressure up to 15 bar. The application options range up to a capacity of 110 m³/h.
Both the complete pump parts and the gear drive are made of stainless steel. The pumps can be cleaned without any effort, which speeds up maintenance. The ability to install the pump with vertical (self-draining) connections allows it to be used universally.
The standard series can be used for versatile applications, with rotors specifically developed for the respective medium.
Due to the two or four blades and self-draining feature, the hygienic version is ideal for pharmaceutical or biotechnology applications.
