Diaphragm vaccuum pumps and compressors

Practical aids in the laboratory.
Diaphragm pumps are quiet, maintenance-free, gas-tight and environmentally friendly. They transfer the media uncontaminated. Their operation ensures constant vacuum.
Connection to laboratory equipment and handling of these pumps is simplicity itself. Our line includes versions for normal operation with pump heads made of plastic or aluminium and a neoprene diaphragm. When aggressive media are used, versions with a PTFE-coated diaphragm are available.

KN = Plastic pump head with neoprene diaphragm
AN = Aluminium pump head with neoprene diaphragm
KT = Plastic pump head with PTFE-coated diaphragm
AT = Aluminium pump head with PTFE-coated diaphragm

LABOPORT® diaphragm vacuum pumps

Chemically resistant vacuum pumps - for universal applications.
Designed for universal application in the laboratory LABOPORT® vacuum pumps are a complete replacement for environmentally unsound water jet pumps.
Since LABOPORT® vacuum pumps do not depend on the water connections, they can always be used right where they are needed. They transfer the media uncontaminated, are gas-tight and ensure a constant vacuum while making very little noise. The parts of the pump head coming into contact with gas are made of PTFE and FFPM for chemical resistance.
Motor protection: 1-230 V 50 HZ, IP 44
