ALLDOS announces two TrueDos® flow monitor digital dosing pumps. The 209 Series, for pumping rates as low as 0.005 L/h (0.001 gph), can be adapted quickly and easily to the user-specific process requirements with a straightforward calibration process. Dosing rate is entered in liters-per-hour and the units take care of the rest. Pressure is constantly monitored within the dosing head and alarm immediately on error or loss of chemicals or over pressure within the discharge line. Series 222 pumps (for digital dosing of high-viscosity media up to 2,600 mPa) extend the rates up to 150 L/h (39.63 gph). They can also be Profibus-enabled and have integrated diaphragm rupture detection. The units are dual voltage 110-230V, one pH, 50/60Hz, IP65 with an optional 24V DC version.www.alldos.com
