D50 High Vacuum High Flow Dual head Diaphragm Pump

D50 High Vacuum High Flow Dual head Diaphragm Pump

The dual-head D50 series includes two models: the D50VB and D50FB. The D50VB offers higher vacuum performance, while the D50FB delivers greater flow rates. Both models operate at 24V and can also function as positive pressure pumps, capable of generating up to 50kPa of positive pressure.the dual-pump heads support flexible configurations—they can be connected in series, in parallel, or operated as two independent pump units to adapt to various application requirements. Designed for industrial durability, these pumps can run continuously under maximum load 24/7, with a proven lifespan exceeding 7,500 hours in full-load endurance testing.

Overall Descriptions

The D50 series are high-vacuum, high-flow dual head diaphragm pumps with a 24V operating voltage. They achieve a relative vacuum level exceeding -98kPa and a maximum flow rate of up to 22L/min. These pumps feature premium brushless motors, allowing speed adjustment via PWM duty cycle control. Multiple pipe fitting options are provided, including PC6, PC8, Rp1/8, NPSC1/8 cylindrical internal threads, as well as hose connectors, meeting diverse customer requirements for pipeline connections.
Dual head Diaphragm Pump

Powerful Suction,High Flow

The D50VB vacuum pump delivers exceptional performance with a vacuum level up to -98kPa(3kPa.abs) and a peak flow rate reaching 13L/min. Its balanced high-vacuum and high-flow design caters to critical processes like gas sampling, analytical instrumentation, and automated systems where both speed and suction depth are essential.

High Flow,High Vacuum

The D50FB vacuum pump delivers outstanding performance with both high flow rate and high vacuum capability, achieving an impressive vacuum level up to -88kPa and a peak flow rate of 22L/min. Despite its remarkably compact design, this powerful unit maximizes performance to fully meet demanding requirements for both strong vacuum and high flow applications.If you need a pump with high air-tightness, please check the D50TS model

Modular Connections

This mini gas pump offers comprehensive connection compatibility with multiple standard fitting options including 8mm and 4mm hose connector,quick-connect PC6 and PC8, , as well as internal threaded Rp1/8 and NPSC1/8 connections.

Dual Head Diaphragm Pump Design

The two pump heads can be connected in series, in parallel, or used as two independent pump heads to meet various application requirements.

Long Lifetime

This pump is equipped with a high-quality brushless DC motor capable of continuous operation, delivering reliable performance with an extended service life of up to 7,500 hours under full load conditions. The premium motor design ensures smooth, maintenance-free operation while providing excellent durability for demanding industrial 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.

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 

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.

Test conditions

Fully-loaded lifetime: Pumps are fully loaded under rated voltage ,the inlet is blocked, and the outlet is directly connected to the atmosphere; the fully-loaded lifetime represents the continuous operating life under the most extreme and harsh working conditions. When the actual working condition is intermittent use or the working pressure is lower than the maximum rated pressure, the product lifetime will approach the unloaded lifetime

Unloaded lifetime: Both the inlet and the outlet of the pump are connected to the atmosphere, and the pump operates continuously for 7*2 4 hours without stopping;

Motor lifetime: The motors run continuously for 7*2 4 hours without load under good ventilation and heat dissipation conditions   

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

EA material tolerance to alcohol, acid, alkali, etc. (except strong acid, concentrated acid, lipids, benzene, gasoline, etc.),PV material has excellent corrosion resistance and tolerance to strong acids, strong alkalinity and various corrosive gases
