High quality positive displacement pumps for industrial applications

Belli Meccanica is a leading company in the production of positive displacement and oscillating hollow disk pumps. In our workshops products of the highest quality are made thanks to the constant commitment to research and development of new production technologies. Thanks to our technical experience and patents, we offer innovative solutions with flow rates from 1 to 500 mc / h and pressure up to 15bar (g) for any type of application and field.

Robust, reliable and high performance

We provide a wide range of positive displacement pumps from oscillating hollow disk pumps, (produced by Belli Meccanica for over 30 years, whose range was completely renewed in 2008) to the latest ones, the positive displacement pumps with rubber impeller, an absolute innovation in the pump sector and designed to operate with low-lubricating and aqueous liquids.

The production includes double and triple body oscillating hollow disk pumps (remember that the hollow disk pump with three pumping bodies is our exclusive invention), up to the magnetic drive pumps range. The materials range goes from simple cast iron and carbon steel for the most basic applications, to the hardened stainless steel, hastelloy, and hard CVD coatings for the most heavy duty applications.

The production of tailor-made pumps specially designed according to the specific application is indeed the great strength of Belli Meccanica. We are able to offer complete pumps equipped with diesel engine and solutions that include the complete package or the pump on skid with electrical panel, piping and accessories.

Quality, innovation and efficiency

Hollow disk pump with internal seal type “C”

Hollow disk pump with internal seal type “C”

Positive displacement hollow disk pump with internal seal. The seal is located internally and the pump shaft is supported on roller bearings. This configuration makes the pump compact and economical but providing good performances. Self-priming with high dry suction capacity, reversible, it tolerates solid parts, reliable and robust in any type of application.

Hollow disk pump with external seal type “L”

Hollow disk pump with external seal type “L”

Positive displacement hollow disk pump with external seal. The seal is located externally inside the rear stuffing box and the pump shaft is frontally supported on bearing bushing. This arrangement makes the pump suitable for heavy duty applications and for continuous service. The particular configuration allows monitoring and replacement of the seal from back without disassembling the pump body.

Magnetic drive hollow disk pump type “MAG”

Magnetic drive hollow disk pump type “MAG”

Positive displacement hollow disk pump with magnetic drive. The magnetic drive coupling transmits the motion to the pump shaft thanks to the use of powerful permanent magnets. Torque transmission occurs without any contact between mechanical parts and the containment canister totally seals the pump from the external environment avoiding any risk of leakage.
