4.2 Description
The ZEPHYR C-KLR is a double shaft rotary piston pressure vacuum pump in which the claws roll off
against each other contact free and dry. The counter-rotating claw rotors are synchronised by a gear pair
in the gearbox. The synchronous gearbox gear wheels and the bearing on the motor side are lubricated
with oil. These components are in a gearbox that also contains the oil supply. Oil conveying devices always
ensure that the bearings and the gear wheels are suffi ciently supplied with oil at all permissible speeds. The
feed chamber has no sealants or lubricants. The gearbox and the compression chamber are separated from
each other by special seals. The gearbox is sealed from the outside with piston sealing rings and O rings,
the compressor chamber with piston rings.
The ZEPHYR C-KLR is enclosed in an insulation hood. In order to dissipate compression heat, the cooling
air is sucked through between the machine and the hood using drum fan that sucks in the fresh cooling air
(Fig. 2/E) and discharges the heated air out of the cooling air outlet (Fig. 2/F). The compressed air aftercooler
(Fig. 2/R) provides a low blowing air temperature.The ZEPHYR C-KLR is driven by standard fl anged three-
phase motors via a coupling (with an elastomer component).
Relief valves (Fig. 2/ZUV) and (Fig. 2/ZBD) are installed as standard to protect against overload..
4.3 Areas of application
These contact free running claw pressure vacuum pumps models C-KLR 80 and C-KLR 140 are suitable for
creating pressure and vacuum at the same time. Constant operation is permissible.
The nominal fl ow rate is 80 and 140 m 3 /h at 50 Hz. The load limits (bars) on the intake and pressure sides
are specifi ed on the data plate (Fig. 2/N). Data sheet D 883 shows the dependency of the fl ow rate on the
excess pressures.
If the unit is switched on more frequently (at regular
intervals of about 12 times (C-KLR 80) or 10 times
(C-KLR 140) per hour or at higher ambient tem-
peratures and intake temperatures, the excess tem-
perature limit of the motor winding and the bearings
may be exceeded.Please contact the manufacturer
should the unit be used under such conditions.
If it is installed in the open air the unit must be pro-
tected from environmental infl uences, (e.g. by a pro-
tective roof).
