Operating Instructions
Side channel vacuum pumps / Side channel compressors
Pump ranges
These operating instructions concern the following side channel vacuum pumps and compressors: SAP
The performance curves showing capacity against vacuum or pressure can be seen in data sheets D 545 / 1, D 545 / 2 and
D 545 / 3 or D 645 / 1, D 645 / 2 and D 645 / 3.
Description
All SAP models work according to the dynamic compression principle utilising a non contact rotating impellor. They have
a built-in motor. A high efficiency double-flow impellor is fitted on to the motorshaft. Models up to SAP / 4 kW (picture
ᕡ)
use the motor fan for cooling. Models SAP / 5.5 kW and larger (picture ᕢ) have an additional cooling fan situated
between the motor and blower housing.
Air inlet and outlets have built-in silencers with the addition of a mesh disc on the suction silencer to protect the unit from
particles larger than 5 mm. Both the inlet and outlet have an inside connection thread corresponding to DIN ISO 228.
Versions of the SAP have on the suction side a solenoid valve and on the pressure side different connection flanges.
All the parts are made from a special aluminium alloy except for the motor rotor, stator and shaft.
Optional extras: As required, vacuum or pressure limiting valve, non-return valve, suction filter, motor starter, vacuum/
pressure change over valve.
Special versions: anti corrosive internal coating, gas tight version.
