Torque Flow Pumps, Vortex Impeller
The Rotamac RT series can handle solids up to full diameter size of discharge connection without danger of clogging. The vortex impeller does not impart energy directly to the liquid. Instead it creates a whirlpool, best described as a vortex. The vortex in turn imparts energy to the liquid or pumpage. The location of the impeller is usually above the volute, so it experiences hardly any radial forces. Available in vertical sump configuration VS4, VS5.

Flow rate: up to 1,500 m³/h
Head: up to 100 m
Solid handle: up to 250 mm
Shaft seals: gland packing, mechanical seal

Chemical Process Pumps with Semi-Open, Open and Non-clog impeller
Choosing the right impeller helps to avoid clogging and achieve the highest possible efficiency. ROTAMAC offers pump impellers for all processes in solid-handling application.

● The semi-open type impellers are more efficient due to the elimination of disk friction from the front shroud and are preferred when the liquid used may contain suspended particles or fibers.
● The open impellers and non-clog impellers are designed for liquids containing larger solid particles, abrasive liquids or stock up to 6 % consistency.

Self Priming Pumps
