Pump Construction

pumps structure

The diaphragm pump circulates and drives the air flow through the reciprocating motion of the diaphragm and the opening and closing of the one-way valve group in the pump chamber, so negative pressure and positive pressure are generated.

Pumps features: oil-free, low power consumption, durable, maintenance-free, multiple options of brushed and brushless.

Let's start

Customization of parameters


Air pumps (1-7 bar, 0.5-80 LPM)
Vacuum pump (30-85kpa, 1-30LPM)
Liquid pump (100-150psi, 0.1-2LPM)

Beauty Instruments

Beauty instruments mainly use the negative pressure of the pump, that is, the micro vacuum pump, according to the size of the instrument, the most frequently used negative pressure is -60kpa, -70kpa, -80kpa, -85kpa, -90kpa. 


Environmental Protection

Common applications are gas sampling pumps, environmental monitoring pumps, automotive emission reduction, spray disinfection. Generally choose low power consumption, high flow rate, continuous working gas pump.

More Applications

Air Pumps: medical and health equipment, mainly used in analytical instruments, negative pressure therapy, suction apparatus, physical therapy instruments. Industrial equipment, such as SMT placement machine, vacuum control suction cup.
Liquid pumps: such as ink pump, fragrance water pump, paint spraying, chemical liquid transfer and other corrosive liquids.
