The new solenoid-driven metering pump gamma/ XL is the enhancement to our proven gamma/ X and covers a capacity range from 8 – 80 l/h at 25 – 2 bar. The gamma/ XL also has other interfaces, for example CAN bus and Wi-Fi connections. This allows the gamma/ XL to network with all systems, devices and platforms. Like the gamma/ X, the gamma/ XL has an intuitive operating concept. The pump is adjusted using a click wheel and 4 additional operating keys. Pressure detection without wetted parts ensures maximum operational safety. Hydraulic error statuses, like “Gas in the dosing head”, “Overpressure” and “No pressure” can be detected.

• Illuminated 3” LCD and 3-LED display for operating, warning and error messages, visible from all sides
• In non-automatic mode, stroke rate setting 1 stroke/h – 12,000 strokes/h, stroke length electronically continuously variable 0 – 100%, recommended 30 – 100%
• Factor with external contact control 99:1 – 1:99
• Batch operation with max. 99.99 or 99,999 strokes/start pulse
• Connector for 2-stage level switch
• 3 additional ports, switched as digital inputs or outputs
• Optional 0/4 – 20 mA output for remote transmission of stroke length, stroke rate and error messages
• Optional relay module with 1 x switchover contact, 230 V – 8 A
• Optional relay module with 2 x On, 24 V – 100 mA

• Simple adjustment of the capacity directly in l/h or in gph
• Integrated pressure measurement and display for greater safety during commissioning and in the process
• Bluetooth and Wi-Fi connection for the simple configuration and call-up of process data (optional)
• Capacity adjustment range 1:40,000
• Direct input of the required final concentration with volume-proportional metering tasks in concentration mode
• Virtually wear-free solenoid drive, overload-proof and economical
• Suitable for continuous micro-metering from approx. 5 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
• External control via potential-free contacts with pulse step-up and step-down
• External control via 0/4-20 mA standard signal, scalable
• Integrated 1-week/1-month timer
• Guaranteed metering by means of automatic bleeding
• Connection to process control systems via a BUS interface, such as PROFIBUS^®, PROFINET^®, CAN bus or Wi-Fi
• Automatic mode – volume settings only (l/h, ml/contact etc.)
• Non-automatic mode – settings via stroke length and stroke rate
