Product Introduction
The fully automatic dosing equipment primarily consists of a dosing tank, a dosing metering pump, an automatic control system, a safety valve, a buffer, a filter, detection instruments, and pipe fittings and valves. All these components are installed on a fixed base frame.
The dual-pump single-control combined automatic dosing device consists of one dosing tank, two metering pumps (mutually standby), one set of AC variable frequency automatic dosing control system, pipe valves, and a base frame.
The three-pump dual-control combined automatic dosing device consists of two dosing tanks, three metering pumps, three sets of AC variable frequency automatic dosing control systems, pipe fittings, valves, and a base.
Working Principle
Through automatic sensing, data-driven decision-making and closed-loop control execution, the intelligent reagent precise dosing system realizes the leap from "experience dosing" to "intelligent precise dosing".
Equipment Selection
1. Material selection:
Chemical Type | Tank / Piping | Pump Head | Seal / Diaphragm |

| Strong acid (sulfuric acid, hydrochloric acid) | PVDF, PP | PVDF, PTFE | PTFE, FKM |
| Strong alkali (NaOH) | Carbon steel lined with rubber, 316L | 316L, Hastelloy | PTFE |
| Sodium hypochlorite, ClO₂ | UPVC, PE | PVDF | PTFE |
| PAM, PAC | PE, PP | PVC, 304 | EPDM |
2. Selection of dissolution/storage units
Single bucket (50-2000L): PE/PP; Liquid pharmaceuticals, small systems
Double bucket (one in use and one backup): continuous production, non-stop liquid change
Three chamber dissolution device: dedicated for dry powder PAM; Maturation silo → Mixing silo → Storage silo
Large storage tanks (>5m ³): carbon steel lined with adhesive/304/316; Municipal and chemical engineering systems
