Capacity range 2.3 – 45 l/h, 25 – 2 bar
The solenoid-driven diaphragm metering pump gamma incorporates a wealth of eXcellent ingenuity! With integrated pressure measurement, it ensures the smooth running of your metering process. The gamma/ X is ideal for all metering work involving liquid media.
gamma/ X – the proven best-seller intelligently extended
The new solenoid-driven diaphragm metering pump gamma/ X is user-friendly and has an outstandingly long service life, just like its predecessor. An ingenious solenoid control measures the back pressure and protects the system from overload. This technology makes a pressure sensor superfluous, meaning that operating safety can be significantly increased: no additional parts come into contact with the feed chemical, there are no additional sealing surfaces and no electronic components come into contact with the feed chemical. Whether the metering volume fluctuates or hydraulic failures affect the metering process – the gamma/ X keeps everything at your fingertips.
It independently ensures a trouble-free metering process and should the pump ever need maintenance its service module draws attention to this.
- Simple adjustment of the capacity directly in l/h
- Direct input of the required final concentration with volume-proportional metering tasks in concentration mode
- Integrated pressure measurement and display for greater safety during commissioning and in the process
- Virtually wear-free solenoid drive, overload-proof and economical
- Suitable for continuous micro-metering from approx. 1 ml/h thanks to the regulated solenoid drive
- Detection of hydraulic malfunctions, such as gas in the dosing head, and no or too high back pressure ensures smooth processes
Field of application
