TrueDos 222 extends the features of the TrueDos 209 series (0.004 to 20 l/h) to higher rates of up to 150 l/h, and many special features have been developed for equally special dosing tasks.

Two-step Slow Mode:

TrueDos 222 offers reliable and digital dosing of high-viscosity media up to 2600 mPa/s

The Two-Step Slow Mode function decelerates the suction stroke systematically, and with the specially developed valve combinations high process quality, even for the most viscous media is ensured:

• Slow Mode 1 (approx. 60 % of the maximum dosing rate) allows media up to 1000 mPa/s to be dosed
• Slow Mode 2 (approx. 40 % of the maximum dosing rate) manages even extremely viscous media up to 2600 mPa/s This represents huge cost savings for the user as he can now add expensive chemicals directly, without connecting dilution or treatment systems.

Optional diaphragm monitoring with innovative double diaphragm technology for optimal process reliability.

In applications where the dosing diaphragm is monitored and the process must not be interrupted in the event of a diaphragm rupture there is one optionally integrated double diaphragm system with a differential pressure sensor for TrueDos 222. If there is a working diaphragm defect, the pump continues to dose with the equally robust protective diaphragm. The system immediately sends a diaphragm rupture signal and initiates remedial measures.

Cost-effective

Thanks to the advanced EC motor technology, energy costs are kept at a low and maximum efficiency is also ensured. At dosing rates of 150 l/h, it offers smooth and virtually continuous dosing. This produces remarkably smooth pumping and mixing of media, resulting in exceptional process reliability.

The optional Flow Monitor checks the system for excess pressure and dosing malfunctions.
