Pompetravaini – Bora positive displacement lobe pumps are characterised by innovative design and solutions which enhance performance, reliability and low life-cycle costs.
The three- lobe rotor is an evolution of the classic bi-lobe design, shaped like a figure “eight”. This design ensures higher bending stiffness, and lower pulsation amplitude which consequently reduces vibration. The economic advantage in bearing life is appreciable.
The synchro-gears are case hardened and tempered. Gears are accurately ground to ensure optimal timing. The “long addendum” involute design gives maximum efficiency with virtually silent mechanical operation. This design allows the vacuum boosters to be installed without a sound canopy.
Mechanical noise is kept to a minimum as a result of accurate design and assembly. The gear lubricant is a long lasting, low viscosity PAO oil which enhances machine cooling. The lubricant can be supplied “food grade” for certain applications. These feature all help to decrease the machine’s life cycle costs.

Pump body, sump and covers are assembled with flat gasket (blowers/exhausters) or O ring seals (Booster HV) to ensure maximum tightness. This results in increased reliability which decreases maintenance costs.
Sealing of the rotors is achieved with labyrinth seals, which do not contact, and, therefore, do not create friction. This is ideal for the rotor’s high rotational speed. This solution saves money due to the decrease in energy dissipation, and the absence of any other expensive cooling system.
Shaft sealing with double Silicon Carbide/Graphite mechanical seals ensures high reliability and durability. The diameter of the of the shaft is specifically designed in order to maximise strength, and reduce peripheral speed, and the associated friction.
