Mechanical diaphragm pumps

OBL Pumps PULSAtronM

Mechanical diaphragm pumps are used for continuous chemical dosing in water and wastewater treatment, chemical processing and other industrial applications.

The diaphragm separates the pumped liquid from the drive mechanism, making these pumps suitable for dosing aggressive and corrosive chemicals. Depending on the model, the flow rate can be adjusted by changing the stroke length or motor speed, or through electronic control.
