Automatic Degassing for Critical Applications!
The Solenoid-Driven Metering Pump gamma/ XL extends the capacity range of the tried and tested gamma/ X to 80 l/h. In addition to the already familiar relays and bus interfaces, the gamma/ XL offers a socket with 3 further configurable inputs and outputs. This means that the gamma/ XL can be networked with all common systems, devices and platforms. Like the gamma/ X, the gamma/ XL has an intuitive operating concept. The pump is adjusted via click-wheel and 4 additional operating buttons. Pressure detection without wetted parts ensures maximum operational safety. Hydraulic faults such as "gas in the dosing head", "overpressure" and "no pressure" are detected.
Pressure fluctuations in the system are detected and compensated for. This ensures high dosing precision and reduces chemical consumption to the required amount.
The last 300 events are recorded retrospectively in the integrated log book. This enables quick root cause analysis and troubleshooting if necessary.
Deviations from the dosing quantity or hydraulic faults are immediately detected and corrected by the gamma/ XL. The pump's operating menu contains ordering information for the required wear parts.
As a smart product, it can also be connected to our web-based IIoT platform. This allows users to monitor their dosing process in real time, avoid downtimes and generate reports fully automatically.
New: gamma/ XL meets hygienic design: a hygienic design liquid end is available for small capacity ranges in the food environment
