Engineered for Flammable, Toxic, and Corrosive Gases. Safety First.
For toxic and flammable gases, sealing is everything. ZIQI uses advanced mechanical seals and pressurized crankcases to ensure zero leakage to the environment.
Seal: Double-acting seal / Magnetic coupling
Safety: Equipped with gas detection probes
Reliability: 100% Tested before delivery
Engineered to meet strict industry standards (API 618 / API 619). All electrical components are explosion-proof (Ex d II B/C T4) for hazardous zones.
Motor: EX-proof variable frequency motor
Material: Stainless steel pipeline / Special coating
Compliance: ISO / CE / ASME available
Expertly handling Inert (N2, Ar), Flammable (H2, CH4), Industrial (CO2, NH3) and Medical (O2) gases with purity protection.
Process Screw:For large flow medium pressure.
Oil-Free Piston:For high pressure (up to 450 bar).
Every unit is engineered to order. We customize based on your specific inlet pressure, discharge pressure, and flow requirements.
