[Hilintec] D28 Speed-Adjustable Positive Negative Pressure Diaphragm Pump
The D28 series is a high-performance speed-adjustable positive & negative pressure diaphragm pump engineered for industrial-grade continuous operation, weighing only 177g with a compact dimension of 59x37x62mm. It delivers an impressive peak flow rate up to 5.0 L/min and a maximum relative vacuum of -50kPa, paired with a 40kPa positive pressure output—realizing dual positive & negative pressure functionality in a miniaturized design.

Maintains ultra-small volume while providing peak flow up to 5.0 L/min, -50kPa maximum vacuum and 40kPa positive pressure. Enables both vacuum suction and pressure boosting in one unit, meeting diverse pressure requirements of industrial applications.If you need a pump with lower flow rate, please refer to D15

The D28 series offers three motor versions to suit different application needs. The DC Brushed Motor (Simplified Version) delivers a 2000-hour full-load lifespan, providing a cost-effective solution for general scenarios. For continuous operation with low electromagnetic interference, the BL Brushless Motor (Standard Version) extends the lifespan to 7000 hours under full load. The BA Brushless Motor (Premium Version) is designed for heavy-duty 7/24 working conditions, featuring a 12000-hour full-load lifespan and a 18000-hour motor lifespan. All motors undergo rigorous life testing.

This mini gas pump offers comprehensive connection compatibility with multiple standard fitting options including 4mm hose connector,quick-connect PC6, as well as internal threaded Rp1/8 and NPSC1/8 connections.
Optimized structural design ensures low operating noise and minimal electromagnetic interference, complying with industrial EMC standards and suitable for precision instrument and medical equipment applications.

Advanced Multi-Protection System
This model features intelligent self-protection with stall protection, over-current protection, and reverse-connection protection. This comprehensive safety system actively prevents damage from high-load conditions, power supply faults, or operational errors, ensuring uninterrupted performance and extended service life.
In response to industrial-grade reliability requirements, we have designed a special test process for possible load conditions. Therefore, no matter what load the product actually works under, its actual service life can reach and exceed its nominal service life. If the actual working load is less than the nominal maximum load, its life can be further extended. Therefore tt can operate without stopping for a long time under the maximum load. The product has passed the life test under the maximum load, and can promise to reach the nominal life under various loads.

Under the premise of extremely compact size, it can achieve flow rate 0.6L/min and maximum positive pressure 70kPa. In such a small volume, the ability to generate such a high flow and pressure is a major feature of this product.
D09Q is a low noise level model designed for noise sensative application. It has a very low noise and vibertion as low as 40Db.
The mini gas pump’s flow rate can be adjusted by controlling the motor speed. For brushless motor (BLDC) models, speed regulation is achieved by adjusting the PWM duty cycle.
