VUOTOTECNICA VTLP105/G1

These vacuum pumps have a suction flow rate of 75, 90 and 105 m3/h. The vacuum with disposable oil lubrication is adjusted via two oilers located in correspondence of the support bearings. The rotor is cantilevered-fitted on the motor shaft and supported by independent bearings housed in the two pump flanges. The pump and the electric motor are, therefore, two independent units and fixed onto a special support and connected to each other via an elastic transmission joint. All this allows using standard electric motors, in the shapes and sizes indicated in the table. The pump is surface cooled. Heat is dispersed from the outer surface, suitably finned, by means of a radial fan placed between motor and pump. An oil recovery tank is installed on the pump exhaust. This tank contains a separator filter that prevents oil mists and reduces noise. A safety valve is also installed on the tank for the automatic drainage of the exhaust oil when not regularly drained. The lubrication oil is contained in a special transparent container, fixed to the pump via its support, and controlled by a magnetic level switch. In pumps with disposable lubrication, the oil is sucked in the pump through an adjustable drip oilers and drained together with the sucked air in the recovery tank, without being put in circulation again. These pumps are necessary when the air to be sucked contains water condensation, solvent vapours or anything else that could affect oil properties. A check valve and a filter must be installed on the pump suction inlet. These pumps are supplied with three-phase electric motors only.
