Circulation pumps with flange connection

Flange

— a flange is a plate with slots for bolts, protruding beyond the dimensions of the pipe and located flush with the hole to which the connection is made. When connecting, two flanges are applied to each other and fixed with bolts. This method of connection is more cumbersome than thread, but also more reliable. Therefore, it is typical for high-performance pumps designed for thick-walled pipelines.
