Chemistry diaphragm pumps and chemistry vacuum systems with ATEX approval
Pumps Vacuum Diaphragm Pumps
Chemistry diaphragm pumps: Chemistry diaphragm pumps in equipment category 2 (e.g. for Zone 1) with ATEX compliance. These pumps are exceptionally well designed for the avoidance of ignition sources. They have good chemical resistance, are oil-free, have no friction surfaces and the suction chamber is hermetically sealed off from the drive unit compartment. Motor with flameproof enclosure and integrated, self contained overcurrent and overheating protection for direct 230 V/60 Hz single-phase connection. Diaphragm pump heads made of anti-static materials. Chemically resistant:More Product Information
