D15 Dual-Head Positive Negative Pressure Mini Gas Pump

D15 Dual-Head Positive Negative Pressure Mini Gas Pump

The D15 series is a versatile micro diaphragm pump that functions as both a vacuum pump and a compressor. It is distinguished by its dual-head design: the D15PB (series connection) is optimized for high pressure (up to 100 kPa positive pressure and -75 kPa relative vacuum), while the D15HB (parallel connection) is designed for high flow (up to 3.2 L/min peak flow). Despite its powerful output, the pump maintains a compact size of approximately 56x49x25mm and weighs only about 80g. Driven by a high-quality BLDC motor, it supports PWM speed control, tachometer (FG) feedback, and features comprehensive protection (stall, over-current, reverse polarity). The standard wetted parts (EPDM) offer good resistance to alcohols, acids, alkalis, and ozone, making it suitable for a wide range of media.

Overall Descriptions

The D15 series is a high-performance Mini gas pump engineered for continuous operation in demanding environments. Designed with a dual-head configuration (available in series for high pressure or parallel for high flow), this pump delivers exceptional vacuum and pressure capabilities within a remarkably compact footprint. Powered by a long-life brushless DC motor, the D15 is built for 7/24 continuous duty, offering industrial-grade reliability for applications such as gas sampling, analytical instruments, medical devices, and industrial automation.

Mini Gas Pump

Dual‑Head High Performance (High Flow / High Pressure Versions)

The D15 series comes in two optimized configurations to match different application demands. The D15PB (series) model delivers exceptional positive pressure (100 kPa) and strong vacuum (-75 kPa), making it ideal for applications requiring high sealing force or strong suction. The D15HB (parallel) model prioritizes volume, achieving a peak flow rate of 3.2 L/min (average 2.0 L/min) for applications requiring rapid sampling or inflation. This flexibility allows you to select the perfect balance of pressure and flow for your specific use case.If you need a single-head pump of this series, please visit D15L

 

Compact Vacuum Pump & Compressor

The overall size of the this high efficiency micro diaphragm pump(equipped with a brushless BL tpye motor) is about 56x49x25mm,it is suitable for applications that require a very small space of air pumps.

 

Premium Brushless DC Motor Drive

Equipped with a long‑life BLDC motor, the pump offers low electromagnetic interference, low heat generation, and high efficiency. It supports full‑load restart capability and stable continuous operation even under maximum pressure or vacuum load, ensuring consistent performance in demanding environments.

 

Complete Self‑Protection Mechanism

The pump integrates multiple safety protections: over‑current protection, locked‑rotor protection, and reverse‑polarity protection. These prevent damage from miswiring, excessive load, or system faults, improving overall system stability and service life.

 

Industrial-grade Reliability

Unlike pumps designed for intermittent home use, the D15 is built for the rigors of industrial applications. It has passed rigorous life tests at our dedicated aging and life laboratory. The pump is designed for 7/24 continuous duty under maximum load (e.g., fully stalled inlet or outlet). It achieves a 6,000-hour full-load lifespan, an 8,000-hour no-load lifespan, and the BLDC motor itself has a design life of 10,000 hours. This reliability ensures minimal downtime and a longer operational life for your equipment.

Speed Control Function for Mini Gas Pump

For brushless motor version, the flow rate of the pump can be changed by adjusting the motor speed through PWM signal.

 

Reliable Start-Up Under Full Load

A common issue with many miniature pumps is the inability to start under a significant pressure differential. The D15 excels in this area. It is designed for stable and reliable start-up even when operating at maximum positive pressure (100 kPa) or maximum vacuum (-75 kPa). Furthermore, it can run continuously under these extreme loads without damage, providing exceptional robustness for your most challenging applications.

Compact, Lightweight & Easy Installation

Weighing only 80g, the pump has a miniaturized outline for tight‑space integration. It supports anti‑vibration mounting feet to reduce noise and transfer. Standard 3 mm ID hose barb connectors allow fast, secure tubing connection.

Test conditions

In a clean and non-corrosive laboratory, the pump is fully loaded (the outlet is blocked, the inlet is directly connected to the atmosphere) or unloaded (the inlet and outlet are directly connected to the atmosphere), and runs continuously around the clock; ambient temperature: 5~33 degrees, relative humidity: 50%-85%, fluctuates with the climate.

Working Condition

Operating temperature

Permissible ambient temperature is 0~50 degrees, it is not suitable to be exposed to the sun, and it should work in a clean and ventilated environment

Medium

Permissible temperature of the medium is 0~40 degrees, the transferring gas is allowed to be rich in water vapor, but cannot contain solid particles

Wetted materials
