APPLICATIONS
Chemical Dosing Pumps for Water Treatment & pH Control
Keep pH, flocculation and disinfection on target — reliably, day after day. PERIFLOW peristaltic dosing pumps meter chemicals precisely, without valves to clog or seals to leak.
Why Peristaltic for Dosing
Why Chemical Dosing Needs Peristaltic Pumps
Chemical-Resistant Tubing
PTFE-lined and reinforced tubing handles acids, alkalis, coagulants and flocculants — while the pump mechanism never touches the chemical.
Self-Priming & Run-Dry Safe
No check valves to clog, no prime loss after a suction line empties. The pump re-primes automatically and tolerates dry running safely.
Precise Metering Up to 6 Bar
Accurate, repeatable dosing of pH control agents and flocculants at system pressures up to 6 bar, with ±1% flow repeatability.
Low Maintenance, Long Tube Life
One consumable — the tube. No valves, diaphragms or seals to rebuild, keeping chemical rooms cleaner and simpler to run.
DOSING SCENARIOS
Chemical Dosing Application Scenarios
| Application | Typical Requirement | Recommended Product |
|---|---|---|
| pH control dosing | Continuous, precise acid/alkali addition, fast response | Dosing pumps |
| Flocculant & coagulant dosing | Viscous polymer metering without shear damage | Dosing pumps, pump heads |
| Chlorine & disinfectant dosing | Chemical-resistant tubing, reliable metering | Dosing pumps |
| Antifoam & biocide addition | Small, repeatable doses, remote control | Dosing pumps |
| Boiler & cooling water treatment | Pressure up to 6 bar, unattended operation | Dosing pumps |

Chemical Dosing Questions
Can a peristaltic pump dose aggressive chemicals?
Yes. The chemical only touches the tube bore, so PTFE-lined or reinforced tubing is chosen to match the chemical — and the pump head itself stays clean.
What happens if the chemical tank runs empty?
The pump simply runs dry without damage and re-primes automatically when liquid returns — no air lock, no burnt seals, no priming pump required.
What pressure can your dosing pumps handle?
Our dosing pumps meter reliably at system pressures up to 6 bar, covering most water treatment and process injection points.
How accurate is chemical dosing?
Digital speed control gives ±1% flow repeatability, so pH correction and flocculant addition stay consistent even at low flow rates.
Do the pumps support external control?
Yes — analog 4-20mA, external trigger and RS485 options allow integration with pH controllers, PLCs and SCADA systems.
How often do I need to replace the tubing?
Tube life depends on chemical, speed and pressure — typically weeks to months. Tube replacement takes minutes and costs a fraction of rebuilding a diaphragm pump.
