CE & ISO 9001:2015 certified manufacturer · Est. 2014 · 150,000+ installations · Greater Noida, India
The OZ India Ozone Recirculation Pump is used to recirculate water from the ozone contact tank outlet back through the ozone injection point, increasing ozone contact time and achieving the required CT value. All wetted parts are SS316L stainless steel — ozone rapidly degrades standard pump materials including cast iron, bronze, and standard rubber seals. Available from 0.5 HP to 5 HP to match any ozone contact system flow requirement. Mechanical seals are PTFE-based for ozone resistance.

Frequently Asked Questions
Ozone-compatible materials include PVDF (polyvinylidene fluoride), PTFE, 316L stainless steel, titanium, and silicone. Ozone attacks and degrades: PVC, natural rubber, neoprene, most plastics and elastomers, and copper (at concentrations above 0.3 mg/L). All Ozone India Technology accessories use PVDF or SS316L construction.
A venturi injector creates a low-pressure zone as water flows through the narrowed throat, drawing ozone gas into the water stream by the Venturi effect. The resulting micro-bubbles dissolve at 85–95% efficiency. The water must be at sufficient pressure (1–3 bar) and flow (matched to the injector's rated flow range) for effective ozone transfer.
Yes. All fittings used with PVDF ozone pipe must also be ozone-compatible — PVDF compression fittings or 316L stainless steel fittings are used. Standard PVC fittings must not be used with ozone pipework. All Ozone India Technology PVDF pipe and fittings are pre-certified for ozone compatibility.
Ozone India Technology static mixers are sized to match the ozone generator's sidestream or main water flow and are available for flow ranges from 0.5 m³/hr (50 mm pipe) to 100 m³/hr (200 mm pipe). Static mixers achieve >95% ozone dissolution efficiency when sized correctly for the water flow rate.
