What Are the Dimensions and Installation Details?
For stable performance and long life, connect the miniature DC piston pump using short, soft silicone or PU tubing with airtight fittings and minimal bends. Horizontal installation is preferred; side mounting is allowed, but inverted installation should be avoided. Avoid heavy loads on the pump head. For reliability, add a filter for dusty air, a muffler for noise, a buffer tank for pressure stability, and a check valve for vacuum use.

How Do I Choose the Right Version of This Miniature DC Piston Pump?
The Miniature DC brush piston pump BD-07A/V-M can be configured with different motors, control methods, and sealing materials.
Choosing the correct version depends on lifetime, noise, control method, and working media.
For a Beauty Device
1.If you need longer lifetime, choose a brushless version.
For devices that run frequently or for long periods, lifetime becomes important.A brushless pump usually provides longer service life, lower wear, and more stable performance than a brushed motor version.
2.If you need lower cost, choose a brushed version.
For cost-sensitive products, the brushed motor version is usually more economical while still providing reliable performance for normal duty cycles.
3.If you need adjustable airflow or suction, choose PWM control.
Some devices require different working levels.A PWM control version allows flexible speed adjustment and more precise flow control.
4.If the pump may contact corrosive gas or moisture, choose suitable sealing materials.
For special gases, humid air, or chemical environment, materials such as FKM or PTFE can improve sealing performance and durability.
