Series
Electro servo unit (For AH) series
 |
|
By setting up the electro servo unit to a ADONY® diaphragm metering pump AH series model, the pump discharge can be adjusted automatically according to a flow, pH, turbidity or other signal controller.
The discharge adjustment unit was placed in the central control room previously and is now integrated into the pump.
In addition, a wider range of controls is achieved by using the servo unit together with the inverter. |

Plunger type metering pump SK series
This pump has a wide range of applications such as high pressure line metering in chemical factories,
boiler drug infusion,built-in equipment metering, etc.
It succeeds in being able to withstand long-time usage due to its solid construction.
By regulating the crank portion’s stroke length, the plunger pump has a linear variation between 0 and 100%. |
