Dosing pump

WDPHCL system integrates a control instrument and two proportional metering pumps and it is the perfect solution for specific dosage need like that of swimming pools sector.

It is equipped with backlit LCD display, encoder control, PVDF pump heads and liquid ends, stand-by, flow sensor input, programmable delay at dosing startup, pH priority dosage, service menu with probe reading value, probe check-up and alarms.

RS485 output enables remote control of WDPHCL through the exclusive ERMES system.

WDPHCL system has acid/base (pH) and chlorine/bromine dosing parameters
