Solenoid-Driven Diaphragm Dosing Pump
Electromagnetic Precision, Adjustable on the Fly
A solenoid-driven diaphragm pump uses an electromagnet to pulse a PTFE-faced diaphragm back and forth at a set stroke length and frequency. Each backstroke draws chemical in through a ceramic-ball check valve; each forward stroke pushes a fixed dose out through a second check valve — with no rotating seals in contact with the chemical. Dosing rate is adjusted two ways: stroke length (a manual dial, for coarse constant-flow adjustment) and stroke frequency (electronically, on digital models, for proportional dosing driven by an external signal, pulse count, or ppm setpoint). A PVDF pump head keeps the wetted parts compatible with the aggressive chemicals common in industrial, water treatment, and swimming pool applications across Malaysia.
Electromagnetic actuation — no motor or gearbox, just a solenoid coil pulsing the diaphragm at a set frequency
Dual adjustment — stroke length for coarse flow setting, stroke frequency for proportional/digital dosing
PVDF head, ceramic balls, PTFE diaphragm — wetted parts built for chemical compatibility and long service life
