Electromagnetic Diaphragm Pumps

We, SRS Pumps are reputed manufacturers and suppliers of Dosing Pumps, Metering Pumps, Electromechanical Dosing Pumps, and Industrial Metering Pumps. These pumps are used where fluids must be dosed into a medium with a highest possible grade of accuracy with a defined volume and within a defined time period.

The electro magnetic metering pumps are used in low pressure and low flow applications. The drive unit consumes less energy than motor driven pumps. The pump capacity is varied by both stroke length and speed controls.


These Dosing or Metering Pumps (oscillating positive displacement pumps) suck in a defined volume with the backstroke of the displacer and press it into the dosing line with the pressure stroke. Adjusting the stroke volume and the dosing strokes per time unit can regulate the metering capacity.

FA series- Solenoid driven metering pumps are controlled by an Electronic circuit comprising of professional PCB & electronic components of proven quality for high reliability to the user.
