A compact and lightweight design is used that is perfect fit for built-in applications and for waste recovery. A structure with high corrosion resistance and enhanced reliability / durability enables continuous operation for an extended period of time and ensures long life.

The motor-driven diaphragm pumps are oil-free and are most suitable for usage requiring clean gas and liquid transfer. A wide variety of models are available for various usage. Self-priming capability makes end user’s piping easily.

To improve sealing performance even when the pump is stationary, a unique valve is designed to be pressed against the valve seat. A flush groove design is adapted in the valve seat to prevent accumulating debris when the debris is accidentally mixing in the pumped liquid. The flush groove helps to prevents accumulating the debris between valve and the valve seat reducing a self-priming failure.

The diaphragm is made thick regarding its moving parts, in order to withstand the pump pressure in gas-liquid transferring.
