Each dosing skid is fully assembled, wired and wet-run tested in our Shanghai factory — connect the chemical lines and power on site, and it runs. Single-pump or duplex duty/standby configurations, from simple timer control to PLC-based automatic dosing with remote monitoring.
Duplex duty/standby design — two metering pumps with automatic changeover keep dosing online while one pump is serviced
Metering pumps 1-60 L/h, up to 10 bar — SEKO or Newdoz electromagnetic and mechanical diaphragm pumps; Grundfos fitted on request
UV-stabilised PE dosing tanks 60-200 L with level sight tube; low-level switch and refill alarm available
Control from timer to PLC — conductivity / ORP controlled automatic injection with Modbus RTU output to your BMS
Corrosion-resistant build — SS304 or SS316 skid and manifold; PP / PVDF wetted parts for aggressive chemicals
Every skid pressure-tested and wet-run with water — test report, wiring diagrams and English manual ship with the unit

All models are customisable — send your chemical, dose rate and pressure for a tailored design. FOB Shanghai, packed in ISPM-15 export plywood boxes.
Ideally: chemical type and concentration, dosing rate (L/h), system pressure, preferred tank volume, power supply and control preference. Even two of these are enough — we will propose the rest and confirm with a GA drawing.
One unit. We are a custom workshop and are glad to start with a trial order before you scale up.
15-20 working days for standard models, 25-30 working days for custom builds, counted from receipt of deposit and drawing approval.
Yes. OEM nameplates, English manuals and neutral export packaging are available for distributors and EPC contractors.
ISPM-15 export plywood boxes. The pump set, tank and piping are fixed to the skid; gauges and delicate parts ship protected. DDP to selected markets on request.
12-month warranty on the complete unit, lifetime remote technical support by email and video call. For remote sites we recommend a spare pump and seal kit shipped with the order.
