Generally, shampoo, shower gel and other care plastic packaging bottles are equipped with lotion pumps, which are widely used. Brands or buyers need to refer to many factors when choosing a lotion pump.

1. For the sake of safety, it is necessary to judge whether the raw materials and materials of the emulsion pump are compatible. Lotion pump manufacturers

2. Choose the specifications of the emulsion pump according to the use of the product. There is a formula: recommended usage = (1-2) * pump output.

3. Choose according to the product's capacity specifications and expected use times. Generally, one pack is used 100-300 times. Lotion pump manufacturers

4. According to the specifications of the emulsion pump and bottle mouth, the common calibers are 18 mm, 20 mm, 22 mm, 24 mm, 28 mm, 33 mm and 38 mm; common specifications are 400, 410, 415.

When choosing an emulsion pump, you need to ensure the sealing function of cleaning and protecting the plastic packaging bottle, because this is a key factor in product storage and transportation.

The emulsion and bitumen are delivered to the colloid mill at the same time. If the inlet of the colloid mill presents a positive pressure, the asphalt pump adopts a positive displacement pump. If the head of the emulsion pump is low, the bitumen will enter the emulsion system. At this time, the selection of emulsion pump adopts high-lift pump. Emulsion is a diluent of water and emulsifier. Whether it is a cationic asphalt emulsifier for road emulsified asphalt, or an anionic asphalt emulsifier for waterproof emulsified asphalt. It is corrosive to a certain extent, so pay attention to corrosion resistance when choosing a pump. Lotion pump manufacturers

The stainless steel gear pump relies on the small gap between the gear and the cavity to ensure the high lift of the emulsion pump. After using the emulsified asphalt equipment, the cavity and gear are corroded by the emulsion, and the gear is worn (the gear is more easily worn by the water emulsion). The mechanical fit gap becomes larger, and the emulsion pump head gradually becomes smaller. This is also the reason why the equipment that was able to produce high-content emulsified asphalt could not produce such a high content after one year.
