Miniature pumps are characterized by small volume, compact structure, relatively low flow and head; most of their power source is electric, and a very few adopt the type of drive of pneumatic or manual operation.
Miniature pumps have all kinds of types. According to the medium to distinguish, it can be divided into air pumps, liquid pumps. Air pumped through the fluid is a gas, such as conventional atmospheric pressure of air, hydrogen, ozone, etc. Liquid pumps through the fluid is liquid, such as the most common water, disinfectant water (hypochlorite, hydrogen peroxide, 75% alcohol, etc.), oils (white oil, vegetable oils, etc.), viscous liquids (hand sanitizer, laundry detergent, shampoo, etc.), corrosive liquids (hydrochloric acid, sulfuric acid, etc.). According to the material to distinguish, there are diaphragm pumps, aluminum pumps, and so on. According to the working mode to distinguish, there are diaphragm pumps, piston pumps, gear pumps, peristaltic pumps, centrifugal pumps, piezoelectric pumps, and so on.
Miniature pumps are widely used in electronic equipment, medical and health care, automotive equipment, industry, and scientific research, greatly improving people's quality of life.
