NRTL Certified Compact Oil-Free Diaphragm Pump Made in Germany - OFDP2-LD

The EQ-OFDP-2 is a two-stage, dry compressor vacuum pump. The pumps are positive displacement pumps with a periodic change of size of the suction chamber produced by the movement of the diaphragm. The gas flow caused the valves to open and close automatically. The pump units are directly connected to the drive motor. It is an ideal tool for applications where a dry and oil-free vacuum is required. The vacuum pump is suitable to be used in glovebox with Ar gas
