How does a rotary vane pump work?
-
Does the DS pump meet its base pressure specification with the oil return kit installed?
-
When the oil return kit (p/n 9499376) is connected to the pump, it slightly influences the ultimate pressure of the pump, setting it around 6 x 10-3 mbar (while it stays around 2 x 10-3 mbar without the oil return kit installed).
-
The oil return kit for the exhaust filter connects to the gas ballast port to return oil to the pump. How does the gas ballast operate on a DS pump when the oil return kit is installed?
-
When the oil return kit is installed, a small flow of air works as gas-ballast. It is not possible to increase the air flow, as the port is already occupied by the oil return kit.
How to select, setup and service a rotary vane pump?
-
DS 40M: is the pump supplied with oil?
-
The DS 40M pump is supplied with the first charge of AVF20S vacuum fluid already inside the pump. In order to avoid leaks from the inlet flange, the pump is shipped blanked off.
-
DS 40M: what is the PN for the oil?
-
The recommended vacuum fluid for the DS 40M pump is 0.5 L of AVF20S (p/n X3703-64006).
-
DS 40M: is there a maintenance kit?
-
The maintenance kit for the DS 40M pump is available under p/n X3703-64005.
-
How do I select the voltage on a DS 40M pump?
-
Unlike the other DS series pumps, the DS 40M pump is available in two versions: one developed to operate at 100-120 V, and the other to operate at 200-240 V. The respective part numbers are X3703-64000 and X3703-64001.
-
DS 40M: what is the noise level?
-
The DS 40M pump has been developed for quiet operation. It produces only 45 dB(A) when operated at 50 Hz and less than 48 dB(A) at 60 Hz.
-
What is the difference between a DS “Oil Mist Eliminator” (plastic) and an “Exhaust Filter” (aluminum)?
-
Both filters are designed to retain the oil vapors which would otherwise be expelled from the exhaust port. The exhaust filter (p/n 9499392) has a bigger filtering capacity and is provided with a sight-glass to check the level of the oil recovered. The exhaust filter can be connected by means of the oil return kit (p/n 9499376) to the gas-ballast port of the DS pump to recover the oil inside the pump.
-
When it is suggested to use an exhaust filter instead of an oil mist eliminator?
-
The use of the exhaust filter (p/n 9499392) is recommended whenever the application has a gas load (high working pressure) and the oil recovered by the filter has to be reintroduced inside the pump, avoiding consumption. The oil mist eliminator is suggested whenever the pump works in an application without gas load.
