PPH Vacuum Unit

The PPH vacuum unit of China Xinda Chemical is specially designed for negative pressure processes with highly corrosive media. The core components of the unit (vacuum pump, separator and pipeline) are all made of high-crystallinity polypropylene homopolymer (PPH) or lined with it. The overall seal is reliable and can fundamentally solve the problems of corrosion perforation and seal failure of traditional metal or lined equipment under harsh working conditions such as acid mist and solvent vapor.The system can integrate a variety of vacuum pump types, providing a stable and clean vacuum environment for chemical vacuum distillation, pharmaceutical solvent drying, new energy material degaging and other processes. It has significant advantages such as strong resistance to mixed corrosive media, long service life, and low comprehensive maintenance cost.

Typical Application Industries and Scenarios

Performance characteristics

Excellent corrosion resistance: PPH material (polypropylene modified material) can resist the attack of strong acid, alkali and a variety of organic solvents, suitable for dealing with complex conditions containing corrosive gases, and the service life of the equipment is significantly extended.

High efficiency vacuum control: THE precision seal design ensures the vacuum degree is stable, and the pumping rate meets the strict requirements of industrial production, which can quickly establish and maintain the vacuum environment required by the process.

Stable and reliable operation: The internal structure has been optimized and calibrated, with tight component fit. The failure rate is low during long-term operation, reducing production interruptions caused by equipment downtime.

Environmental protection and economy: Our PPH vacuum unit has lower energy consumption, in line with the needs of energy conservation and emission reduction;Equipment maintenance costs are low, no wearing parts, help enterprises reduce comprehensive production costs.
