Hollow disk pump type C versions
For increasing the flowrate
"C" Series - Single body
"C" Series - Double body
"C" Series - Triple body
Technical features
Exclusive technology for any application
Internal seal
Simple structure with compact dimensions.
Self-priming
Automatically priming with vacuum creation in suction side.
Reversible
Fully reversible with same technical features in both directions of rotation.
Elastic
The elastic device of the oscillating hollow disc allows the passage of solid parts.
Low rotation speed
The low operating speed does not emulsify the liquids and guarantees high reliability.
Atex zone 1 standards
Atex zone 1 compliance for all applications in explosion proof areas.
Working principle
Elastic, simple, robust
The oscillating hollow disk moves inside the body generating two volumes, the suction volume and the discharge volume, separated by the diaphragm. The fluid passes through the openings of the pump body. The hollow disk is kept pressed against the walls of the body by a spring which makes the system elastic and allows the passage of solid bodies. Compared to competitor models, the new range of hollow disk pumps developed by Belli Meccanica starting from 2008, has wider sliding surfaces and reduced eccentricity of the disk. These technical improvements ensure excellent performance and superior reliability.
Technical features of the hollow disk C series pumps
The seal is set internally and the pump shaft is supported by roller bearings. This configuration makes the pump compact and economical, without sacrificing optimal performance.
