This powerful pump technology is especially beneficial for a large number of applications in the low pressure range. The ABEL EM is a mechanically connected diaphragm pump that is very energy efficient because it does not require expensive compressed air to drive it. Their compact special construction does not require hydraulic fluid and can be equipped with high performance depending on the application. Electromechanical diaphragm pumps, with their unique design principles and impressive energy balance, have contributed significantly to ABEL's good reputation.
