FAQ about Corrosive Liquid Filling Machine

Q1: What corrosive liquids can the equipment handle?

A:

• Applicable media: strong acids (such as hydrochloric acid, sulfuric acid), strong alkalis (such as sodium hydroxide), organic solvents, pesticide concentrates, chlorine-containing disinfectants, food preservatives (sodium benzoate, etc.);

• Material guarantee: The core contact parts are made of 316L stainless steel + polytetrafluoroethylene (PTFE) coating/ceramic piston, and the acid and alkali resistance level reaches PH 0-14.

Q2: How to prevent liquid from corroding the inside of the equipment?

A: Triple protection design:

• Material protection: valve body/pipe inner wall composite PTFE coating (temperature resistance -200℃~260℃);
• Structural protection: fully sealed pneumatic system (IP65 protection level) to prevent steam intrusion;
• Active protection: automatic CIP cleaning after filling (optional SIP sterilization) to avoid residual corrosion.

Q3: Can the accuracy meet the ±0.5% requirement of the chemical industry?

A:

• Dynamic accuracy: ±0.3%~0.8% (depending on viscosity), supports closed-loop control of mass flowmeter (optional), real-time compensation of temperature/density changes;
  
  Calibration method: automatic zero point calibration per shift (in compliance with GMP standards).

Q4: Can the equipment be used in explosion-proof environments?

A:
Explosion-proof certified model:
Complies with ATEX/IECEx standards (Ex d IIB T4 level);
The whole machine has a spark-free circuit + grounding static elimination device.
