Overmolded Diaphragms
Overmolded Diaghragms come STANDARD on all Samoa 1:1 DC/DF/DP Series of Pumps. Which allows your pump to run much longer and cleaner than standard diaphragms.
Frictionless Pivot Valve
The Frictionless Pivot Valve provides fast reciprocal action, minimizing flow pulsation and pump vibration. It contributes to reduced air consumption.
Push Rod PTFE Bushing
The DirectFlo Technology is a unique design where your fluids run through the center of the pump vs the outside. This Push Rod connects the diaphragms and seals the pump.
