MSP Vacuum Pump for Impactor MOUDI Model 100S4 0100-01-0079

SKU: 0100-01-0079

Vacuum pumps are needed to draw the sample stream through MSP cascade impactors and air samplers. The pumps below provide sufficient flow and pressure difference (alternatively a sufficiently large vacuum) for certain impactor models. These pumps include all the accessories (connectors, filters and power cables) needed for reliable operation and optimum performance.

Product Details

These vacuum pumps work according to the rotary vane principle. Pumping action is produced by a series of sliding, flat vanes as they rotate in a cylindrical housing. An eccentrically mounted rotor turns and the individual vanes slide in and out of their slots by centrifugal and pressure-loading forces. This creates a series of air compartments of unequal volume against the wall of the housing. These compartments get larger during the suction part of the cycle, creating vacuum at the intake port and smaller during the discharge portion of the cycle, creating pressure at the exhaust port. The vacuum and pressure flows are free of pulsation because the inlet and exhaust ports do not have valves, and the air is moved continuously rather than intermittently.

Relationship between Air Flow and Pump Pressure

Relationship between air flow and pump pressure for 0100-01-0079 vacuum pumpOperating the vacuum pump at a lower frequency (50 Hz; dotted line) results in a lower air flow than when the pump is operated at a higher frequency (60Hz; solid line).
