PPH Water Jet Vacuum Unit

Xinda Chemical's PPH water jet vacuum units made in China are specially for efficient vacuum pumping in highly corrosive conditions. The main body of the unit is made of high-crystallinity polypropylene homopolymer (PPH) in one piece, with no welds throughout and excellent corrosion resistance. It can withstand the erosion of acid mist, solvent vapor and other media for a long time, fundamentally replacing the traditional metal units that are prone to corrosion.

It integrates multi-stage high-efficiency injectors, an optimized gas-liquid separation system and an intelligent control system. It generates vacuum by water jet and features high pumping efficiency, low operating energy consumption, less prone to internal scaling and easy maintenance.The unit is widely used in harsh vacuum processes in chemical, pharmaceutical and new energy fields, with significant advantages in corrosion resistance, operation stability and comprehensive energy efficiency.

Key Advantages

Core workflow

Our PPH water jet vacuum unit is a device that achieves vacuum extraction based on the principle of high-speed fluid jet. The following is its core mechanism.

Vacuum formation stage: after the water pump is pumped and pressurized, the high-pressure water flow is speared out through the nozzle at high speed to form a negative pressure area, and the gas in the system is inhaled into the injection pipeline.

Gas-liquid mixing and separation: High-speed water flow compresses the gas and forms a gas-liquid mixture. Gas-liquid separation is achieved through a separator, with the gas discharged from the exhaust port and the liquid recycled.

Double adsorption purification: the unit built-in activated carbon, molecular sieve and other physical adsorbent, through the surface molecular gravity to capture gas impurities; At the same time, it is combined with chemical adsorbents such as oxidants or reducing agents, which react with harmful gases and convert them into harmless substances to achieve deep purification.
