These external gear pumps feature versatility, strength and long useful life.Their simple construction ensures limited purchase costs and servicing. Thanks to these basic concepts, together with ever-improving product design and features, research-based on many years of experience, accuracy in material selection, production process followed in great detail and tests on mass-produced parts, our gear pumps have reached top quality standards.
For this reason, our products can work under heavy operating conditions and transmit high hydraulic power. Furthermore, Marzocchi pumps feature good hydraulic, mechanical and volumetric efficiency, low noise level and, last but not least, compact dimensions.
Generally these gear pumps usually consist of a gear pair supported by two aluminum bushes, a body, a securing flange and a cover.
Shaft of the driving gear projecting beyond the flange mounts a twin-lip seal ring (the inner lip being a seal and the outer being a dust seal). An elastic securing ring secures the ring in place.
