1/4 Inch Plastic Air Operated Diaphragm Pump for Sewage - 100 PSI Max Pressure, 5.0 GPM Flow Rate
This 1/4" plastic air operated diaphragm pump is designed for sewage and wastewater applications requiring low pressure operation. The miniature pneumatic pump delivers reliable performance with maximum working pressure of 100 psi and flow rate of 5.0 gpm.
A pneumatic diaphragm pump is a positive displacement pump that uses compressed air as its power source. Compressed air shifts between two chambers via a linked shaft, creating simultaneous back-and-forth motion that forces liquid out of one chamber while filling the other, ensuring continuous fluid transfer.
- Dual-threaded manifolds with internal and external threading
- Horizontal suction and vertical discharge center porting with optional horizontal side ports
