Description

The air inlet and outlet ports have been studied to reduce both noise and heat produced. The increase of heat exchange has been granted by the introduction of a liquid-cooling circuit, which improves the time of the pump use. The vacuum pump is standard fitted with a water-recirculating pump. The correct operation of the vacuum pump is insured by the forced lubrication with piston pump. The oil tank is incorporated. The vanes are of a high-heat-resistant composite material. A special inspection hole in the flanges allows the visual check of their wear. The non-return valve and the 4-ways valve are integrated in the pump.
