MES 70/6E2

EV Vacuum pumps

An electric vacuum pump is used in electric and conventional vehicles to boost the vacuum needed for normal power brakes operation. The 70/6E2 pump featured here is manufactured specifically for electric vehicles by MES Switzerland.

The 70/6E2 has very low acoustic noise and vibration levels, and hardly noticed during operation. The vacuum is controlled by integrated control circuitry consisting of vacuum sensor and solid state vacuum switch. The 70/6E2 has absolute pressure switch and will maintain preset vacuum level cycling on and off on its own between -600mbar (17.7″ Hg)  and -650 mbar (19.2″ Hg).

The power required is 12…15 volts DC directly supplied to the pump all the time, no external switches needed. The vacuum level and hysteresis are not user adjustable and are set at the factory to restore the standard vacuum level regular vacuum assisted power brakes in conventional vehicles are designed for. These pumps also will easily replace the vacuum source in regular vehicles if their stock vacuum pump or intake system no longer function. The vacuum booster tank will decrease frequency of on and off cycling, but is not required for proper operation and will not affect wear or life time of the pump. Without tank the pump will likely pump down every time the brakes are actuated, but there is no impact on the brake operation. Optional mating connector included. 1 year warranty.
