Features of EHN-R-H2 series
Max. discharge pressure: 2.0 MPa (Max. 240 spm).
ideal for boiler chemical injection into pressurized pipelines.*
*Observe the maximum discharge pressure.
Multi Voltage
The use of the multi voltage circuit design allows the pump to work anywhere in the world.
Pump Body
The use of the integrated controller reduces a sealing area, so that the water-/dust-proof design of IP65 is attained. Also, a plastic cover protects the control panel under an adverse environment.
Air Vent Valve
Rotating a standard air vent valve, the remained gas can be easily expelled from the pump head.
