Food Grade PE Pressure Tank Material and water safety Made of foodgrade PE material that is safe for contact with drinking water and meets human consumption water standards Environmentally friendly, waterproof, wearresistant, and pressureresistant Odorless and resistant to low temperatures down to 60 C; will not freeze or crack in winter Working principle and operation Pneumatic water supply with simple operation Automatic pumping when water volume decreases Automatic shutdown when the tank is full Low maintenance and easy to install Delivers water pressure to meet daily water demand Capacity and pressure relationship Actual usable storage depends on the pressure setting; a higher pressure setting yields more storage Water storage is approximately 50% to 70% of the total tank volume Pressure resistance and safety features The tank can withstand up to 6 kg of pressure; working pressure is around 3 kg design includes three holes for separate installation of the pressure gauge, the pressure switch, and the safety explosionproof valve Automatic pressure relief helps prevent overpressure and avoids vacuum/negative pressure conditions Practical applications Domestic potable water system with automatic refill for households Small workshop or cleaning station requiring reliable water pressure Offgrid or remotesite water supply where mains pressure is unavailable or intermittent Why this tank stands out Combines foodgrade material with reliable pneumatic operation for safe, unattended water supply Clear relationship between pressure setting and usable capacity allows flexible system design Builtin safety features and accessible ports support easy monitoring and maintenance
