Low energy cost.
Electricity cost < compressed air cost, high efficient (IE3 class) driveLong diaphragm lifetime.
Pneumatic and mechanical support of the diaphragmRun dry without damage.
Easy to use, no need of guarding deviceLow spare parts cost.
Electric Diaphragm pump has an almost identical design of the wetted side as the standard Tapflo air operated diaphragm pump, therefore many spare parts are the sameSelf-priming from dry suction pipe.
More options of installationClean & easy maintenance.
No hydraulic fluid required, no danger of leakageFew components & long life design.
Low downtime and maintenance cost
The Tapflo electric diaphragm pump is driven by a gear-motor. In this type of pump there is a need to change rotary motion into reciprocating one. It is obtained by an eccentric shaft with a cam and piston. The rotary movement of the shaft (red part) is transferred to the reciprocating movement of the diaphragm shaft (yellow part).
Suction (chamber 1)
One diaphragm creates a suction action in one chamber (right side) when being pulled back from the housing.
Discharge (chamber 2)
The other diaphragm is being moved by the piston to the left. This action creates pressure in chamber.
