External gear pumps

They are simply designed pumps, and are used for medium pressure applications, at around 150-200 bars, often used in bypass filtration/cooling circuits in complex systems, in auxiliary services, in simple applications where no particular performances are required such as flow/pressure (ripple derived from pumping teeth) and noise.

Interfluid carries a large stock of Marzocchi external gear pumps.
