Metering Pump EMEC WDPHRH Series

Metering Pump EMEC WDPHRH Series has been created by EMEC to provide a complete and small-sized solution for swimming pool water treatment. WDPHRH systems are all-in-one, compact instruments which integrate two dosing pumps and a control instrument into a single, easy to use, highly precise system.

WDPHRH systems can measure pH and another parameter that depends on the chosen model; chlorine, bromine, Redox, antialgae, flocculant, active oxygen. A wide range of products for the highest flexibility.

WDPHRH PER: Reliable and Noiseless

WDPHRH proportional dosing systems in the versions with peristaltic dosing pumps (WDPHRH PER) are the best solution to be installed where silent operation and high reliability are required, like in spa and wellness facilities.

The integrated peristaltic pumps are indeed the most suitable for micro-dosing needs with lower pressure, ensuring at the same time an absolutely constant and accurate flow rate. Moreover, peristaltic pumps promise to have low power consumption thanks to low voltage.

Complete Control, Even Remotely

A clear reading of data and an easy browsing through function menus are made simple by a wide backlit LCD display and by the “ENCODER” control knob, in order to quickly program the working modes you need, to set alarms and to manage outputs.

You can also remotely control WPDHRH systems from any smartphone or PC with EMEC exclusive online system ERMES, so to keep the status of your plant always under control whereever you are.
