Pump ranges
These operating instructions concern the following contact-less operating claw vacuum pumps: Models VLR
The vacuum capacities at atmosphere are 100, 235, 300, 385 and 500 m
which show capacity compared to pressure can be found in data sheet D 880.
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. ZEPHYR 400 and 500 have on the B-Side also
greased bearings.
The pumping chamber is separated from the gear chamber using labyrinth seals. The sealing system can be enhanced
with sealing gas (special version).
The ZEPHYR is 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).
All the pumps are driven by a direct flanged three phase, standard TEFV motor via a pin and bush coupling.
Vacuum can be adjusted to the required levels, however, they are limited to a maximum point (see regulating valve (C)).
Optional extras: As required, non-return valve (ZRK), vacuum tight suction filter (ZVF), motor starter (ZMS), exhaust
silencer (ZSZ) (see picture
