The BD-05T60WB is a compact, brushless micro diaphragm liquid pump designed for precise, low-pulsation liquid handling in OEM and analytical equipment. A brushless DC motor drives an elastic diaphragm to create alternating suction and discharge, delivering stable flow while fully isolating the liquid from mechanical parts. This oil-free design ensures clean operation, low leakage risk, and suitability for continuous duty.
With a PPS pump head, EPDM/PTFE diaphragm, and PA66 housing, the pump provides up to 280 mL/min water flow with low noise and vibration. Its ultra-small footprint makes it well suited for inkjet systems, IVD devices, and laboratory instruments where space and reliability are critical.

Q1｜Why is a diaphragm pump suitable for precision liquid dosing?
The diaphragm mechanism generates controlled displacement with minimal backflow, resulting in stable flow and reduced pulsation compared to rotary micro pumps.
Q2｜How does a brushless motor improve reliability in liquid pumps?
Brushless motors eliminate mechanical commutation wear, offering longer lifespan, stable torque output, and improved suitability for continuous-duty applications.
Q3｜What factors affect diaphragm pump chemical compatibility?
Compatibility depends on diaphragm and valve materials. EPDM provides general resistance, while PTFE supports aggressive or high-purity liquids with minimal absorption.
Q4｜Can the pump handle intermittent dry running?
Short intermittent dry running is acceptable, but continuous dry operation is not recommended as liquid is required to dissipate heat and maintain diaphragm durability.
Q5｜What integration points should OEM engineers consider?
Key factors include inlet filtration, vibration isolation, tubing elasticity, and adequate thermal dissipation to ensure long-term stable operation.
Q6｜Is there a brushed motor version of the BD-05T60WB?
Yes. A brushed DC motor version is available for cost-sensitive or simpler control applications:
