These operating instructions concern the following contact-less operating claw vacuum pumps: Models VLR 251
The vacuum capacity at atmosphere is 211 m
Description
The ZEPHYR VLR are two shaft, rotary lobe vacuum pumps, where two claws are rotating contact-less and dry in opposite
directions in a housing and are synchronised by a pair of gears. The pumping chamber is oil free. The synchronised drive
gears and the A-side bearings for the rotors are oil lubricated. The drive gears and the A-side bearings are fitted into a
gear chamber which also contain the oil tank. The oil tank is designed so that at all rotational speeds, bearings and gears
are supplied with the correct amount of oil.
The pumping chamber is separated from the gear chamber using labyrinth seals. The sealing system can be enhanced
with sealing gas (special version).
The VLR 251 are enclosed in a sound box. The cooling takes place over the coupling fan. The fresh cool air (E) is sucked
in and the warm air is exhausted through the vents (F).
The pumps are driven by a direct flanged three phase, standard TEFC motor via a coupling (with Elastomer item).
The vacuum limitation valve (C) is adjusted to a ultimate vacuum of 200 mbar (abs.).
Optional extras: As required, non-return valve (ZRK), vacuum tight suction filter (ZVF), motor starter (ZMS) and soft
starter (ZAD).
