Beta® Solenoid Diaphragm Metering Pump

The solenoid metering pump Beta® is equipped with all setting and control functions for modern water treatment and chemical metering. As compared to its predecessor model, it features a pulse step down and step up function. This facilitates a more accurate adaptation to external signal transducers. The result is an easier and more precise adjustment of the metering to the actual requirements. Thanks to the use of new technologies, the energy consumption could be reduced by approx. 50 %. The Beta® can be easily re-adjusted during operation.

Advantages

Pulse-controlled step up and step down for optimal adaptation to existing signal transducers
For each chemical a matching liquid end
Thus universal use possible
Drive with almost no wear
Excellent permanent operation properties
Optimal price/performance ratio
Energy saving of 50 % thanks to higher efficiency
Adjustable, integrated pulse step up and step down
Optional: Relay module, quick and easy to refit
