Product Description
This brushless diaphragm pump is driven by a BLDC motor. 4-wire brushless speed regulating motor, compatible with both analog and PWM signal speed control.
A brushless diaphragm pump is a type of positive displacement pump powered by a brushless DC (BLDC) motor, where a flexible diaphragm creates a vacuum to move fluids. By eliminating brushes, these pumps offer high efficiency, precise flow control, long service life, and minimal maintenance.
Brushless diaphragm pumps are ideal for applications requiring chemical resistance, accuracy, and sterile operation, such as laboratory dosing, medical devices, and chemical transfer systems.
• Micro Diaphragm Air Pump, compact size with high flow rate, maintenance-free
• Low noise, low vibration
• Precision engineered, high vacuum, ensuring excellent air tightness
• High reliability, superior stability, with a motor continuous operation lifespan of over 10,000 hours.

The BLDC motor drives a cam, eccentric, or mechanical linkage that moves the diaphragm back and forth. This motion creates a vacuum to draw in fluid and then push it through the outlet.
