Lutz-Jesco Dosing Electronic Motor Memdos
Electronic MEMDOS LP dosing pumps are driven by DC motors, which deliver the kind of control that you can’t get with the Memdos LB pumps. If a pump can shift 100 litres per hour maximum, and it can be turned down to 10 litres an hour, it has a 10 to 1 turndown ratio. The Lutz Jesco Dosing Electronic Motor Memdos pumps can give a 200:1 turndown - very fine control that’s easily enough for most chemical dosing requirements, which need a wide range of flow volumes.
The pumps can be run manually to increase or decrease the flow rate. Alternatively, there's flow proportional pulse control, usually using a contact head water meter, or alternatively a process controller.
A remote start/stop control can override all of the inputs from the signals, and the pumps have a low-level alarm output and switch input, so you get an immediate fault indication.
