With their self-lubricating design and no mechanical seal, Taco 00 cartridge circulators provide unmatched reliability that makes them maintenance free. Every Taco 00 and 00 IFC circulator features a field-replaceable cartridge that contains all the moving parts. Replacing the cartridge rebuilds the circulator, so field service is fast and simple. Their wide variety of configurations, flange orientation, mounting and other options, materials and capabilities provide you with great performance in a broad range of applications. Taco 00 IFC Cartridge Circulators feature an Integral Flow Check (IFC) that eliminates the additional installation costs that go along with separate in-line flow checks, improves system performance and further reduces maintenance.
