Rotary Diaphragm Pumps RO-L

The SP Rotary diaphragm pumps are unique worldwide. An extremely pulsating free operation is their outstanding characteristic.

With every turn of the motor three small diaphragms are moved - instead of a large one! This generates a consistent flow of liquids up to 300 ml/min.
