Superior High Airtightness & Low Leakage Performance

This pump is professionally designed for high-airtight working scenarios and adopts a special low-leakage sealing structure. Every product is fully inspected for airtightness before delivery to ensure an extremely low gas leakage rate, which fully satisfies the strict sealing standards of analytical instruments. It is fitted with a 304 stainless steel pump head, matched with EPDM diaphragms, EPDM check valves and FKM sealing components. The mature material combination maintains stable sealing performance even during long-term continuous operation and effectively prevents gas leakage.

High Vacuum & High Pressure Dual Performance

The series includes two core models. D37TSV high vacuum version can reach a maximum relative vacuum of -90 kPa with a maximum output pressure of 50 kPa, perfectly suited for high-vacuum gas sampling and extraction work. D37TSP high pressure version provides stable output pressure up to 300 kPa and a relative vacuum of -65 kPa, ideal for high-pressure gas delivery and circulation tasks.

Premium version achieves 10,000 hours full-load design lifespan, 12,000 hours no-load lifespan, and motor design lifespan up to 15,000 hours. It delivers outstanding durability for long-term industrial and laboratory operation.

 Dual Material Options for Media Compatibility

The D15TS offers two complete material sets to match different gas compositions. The EL material set uses EPDM for the diaphragm, check valve, and seal, making it ideal for air, moisture-rich gases, and mild environments. The FG material set uses FKM for all wetted parts, providing excellent resistance to more aggressive or chemically active gases. This flexibility allows the diaphragm pump to be tailored to a wide range of applications.

Modular & Replaceable Structural Design

Adopt replaceable modular nozzle connector design; optional M3 / M5 internal thread connectors for flexible pipeline matching. The air inlet and outlet nozzle can rotate 360° freely, allowing flexible installation orientation to adapt to complex space layout requirements.

Industrial-grade Reliability

Industrial-grade Reliability 

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.

Speed Control Function for Micro Diaphragm Pump

The flow rate of the high efficiency micro diaphragm pump can be changed by adjusting the motor speed and changing the input voltage. For brushless motor version, the flow rate of the pump can be changed by adjusting the motor speed through PWM signal.
