Serfilco Air Diaphragm Pump

A top quality rugged and durable self-priming, double diaphragm pump supplied by Serfilco. A Lube-free and non-stalling, this pump will handle any product that pours, from clear water to highly viscous, abrasive and chemically aggressive materials. Specially designed features within  the pump enables it  to handle suspended solids and abrasives without damage to the product or the pump.
The unique pump design utilizes far fewer parts than other pumps on the market. This results in longer operating life and easier maintenance at a lower cost.
Since these pumps are driven by compressed air, there is no need for shielded electrical connections or explosion-proof motors. All models can run dry because there are no close fitting or sliding parts in the fluid section. Flow rates can be controlled to produce from zero to maximum flow simply by increasing or decreasing air flow or pressure.
