Membrane dosing pump. The PTM series, featuring all-new power supply technology available from 90 V ac up to 265 V ac and 50-60 Hz, guarantees unprecedented dosing precision and adaptability. Many more functions are now integrated, thanks to the ease of programming, the alpha-numeric display, the multi-language menu programming options and the new technology which allows pool owners to fully control the flow rate and counter-pressure levels, permitting solutions to a wide range of dosing requirements with a single pump, without the need to sacrifice dosing accuracy.
Pump models:
B-type pump of 5-10 bar and 2-5 l / h
C-type pump of 5 bar and 10 l / h
D-type pump of 5 bar and 20 l / h
The analog dosing pumps of the PTM series only require electrical power supply. The flow rate can be set as a percentage using the potentiometer under the front panel, which modifies the pump's operation frequency. Double control scale: PTM analog dosing pumps can divide the maximum dosing frequency by 5. This double scale allows the user to employ two pumps with a single model. The selector under the front panel provides easy changeover. Double regulation: 0-100% and 0-20%. Lubrication and scheduled maintenance are not required. The electrodes and calibration solutions are not included. Also available with peristaltic pump.
