The horizontal pump is horizontally arranged (the liquid inlet pipe is lower than the liquid discharge pipe), and heating gas (set behind the pump or in front of the filter in front of the pump to prevent impurities from entering), seal gas, liquid discharge exhaust valve (discharge at low place and exhaust at high place) and return pipeline (return liquid inlet phase) are required.

The self-cleaning filter generally increases with the increase of gas volume, the number of filter cartridges increases and the number of layers is higher. Generally, it is arranged in two layers above 25000 and three layers above 60000; Generally, a single compressor needs to be arranged with a filter separately and at the upper air outlet at the same time.
