The vacuum PPH measuring tanks of China supplier Xinda Chemical is specially designed for the precise metering of corrosive media in high-end industries. The tank body is made of high-crystallinity polypropylene homopolymer (PPH) through a spiral extrusion winding process in one piece, without welds and with good overall sealing performance. It can stably withstand vacuum conditions and long-term erosion by strong corrosive media such as hydrochloric acid and hydrofluoric acid.
This equipment integrates a precise metering system, enabling precise quantitative dosing and transportation of high-demand materials such as pharmaceutical raw materials and lithium battery electrolytes under negative pressure conditions. It effectively resolves the challenges of traditional material equipment in terms of corrosion resistance and metering accuracy, and is a reliable solution for fields such as fine chemicals, pharmaceuticals, and new energy.
Vacuum PPH measuring tanks are manufactured with large-scale equipment. The cylinder body is formed through the PP extrusion integral winding process. The weld-free design not only enhances the overall structural strength, avoids the possible weak links caused by welding, but also reduces the risk of leakage or failure due to structural defects. The appearance is smooth and beautiful. Its product sizes range from 50L to 5000L, and different series such as vertical or hanging types can be selected according to needs.

Our vacuum PPH measuring tanks are often installed at the front end of a bottom-suction water pump without self-priming function. Its working process is as follows:
Water replenishment stage: Before the pump starts, water is replenished to a certain height through the top water replenishment port.
Negative pressure formation stage: After the water pump is turned on, the liquid level in the tank drops. As the water pump continues to work, negative pressure is formed in the tank.
Material suction and metering stage: When the negative pressure reaches a certain level, the material pressure in the low-level trough is injected into the metering tank, simultaneously achieving accurate metering of the material and control of the conveying volume.
