This Ex d IIC T4 Explosion Proof Motor B5 Flange Mounted is a flange-mounted direct-drive power unit specifically designed for explosive gas environments in industries such as petroleum, chemical, and pharmaceutical. Unlike the B3 horizontal motor, the B5 motor eliminates the foot and uses a D-end cover for vertical mounting, directly connecting to pumps, reducers, or fan impellers via a standard flange.
Feetless Design: The machine stands vertically and is rigidly connected to the equipment via a flange, eliminating the horizontal space occupied by pulleys and couplings. This is particularly suitable for high-risk work positions with limited installation space or dense piping.
CT4-Level Hardcore Protection: Strictly adhering to GB 3836 standards, it possesses Ex d IIC T4 Gb explosion-proof ratings. The high-strength explosion-proof housing can lock internal sparks, controlling the surface temperature to ≤85℃, preventing the ignition of highly reactive hazardous gases such as hydrogen and acetylene.
Direct-Connect High-Efficiency Transmission: The output shaft is directly inserted into the load equipment, resulting in lossless power transmission, smoother operation, and less vibration. It is the preferred partner for chemical process pumps and mixing equipment.
CT4 Highest Safety Standard: Designed for the most demanding chemical environments. IIC-level explosion-proof (protected against hydrogen/acetylene) combined with T4 group temperature (≤85℃) can adapt to most extreme and hazardous locations, providing a "safety fortress" that ordinary motors cannot match.
High efficiency, energy saving, and low noise: Ex d IIC T4 Explosion Proof Motor B5 Flange Mounted adopts an IE3/IE4 ultra-high efficiency magnetic circuit design, coupled with NSK bearings, it not only saves electricity but also operates with low noise and minimal vibration. It maintains a low failure rate and ultra-long lifespan even under harsh conditions such as high temperature, high humidity, and high altitude.
Certification and compliance guaranteed: Each Ex d IIC T4 Explosion Proof Motor B5 Flange Mounted holds CCC explosion-proof certification and an explosion-proof certificate of conformity. For export, it is equipped with ATEX or IECEx certification. Certificates and nameplates correspond one-to-one, ensuring smooth project acceptance.
Widely used in high-risk areas with direct connections in chemical plants, closed systems in pharmaceutical plants, and confined spaces, the Ex d IIC T4 Explosion Proof Motor B5 Flange Mounted, with its unique flange structure, is the preferred choice for the following scenarios:
Chemical process pumps: Directly drives chemical centrifugal pumps and pipeline pumps. The motor stands vertically above the pipeline, saving floor space and eliminating the risk of leakage.
Pharmaceutical closed equipment: Used in pharmaceutical workshops for reactor stirring and vacuum dryers. The B5 flange can be perfectly integrated into the sealed tank, meeting GMP cleanliness requirements.
Direct-drive fans/blowers: Installed on ventilation ducts or explosion-proof air conditioning units, directly drives the impeller, eliminating the need for belt drives and resulting in higher efficiency.
Oil and mining: Extraction pumps and water injection pumps in gas environments, as well as compact equipment for offshore drilling platforms.

Secure Packaging: Industrial wooden crates are used, with special attention paid to protecting the flange face and shaft extension of the Ex d IIC T4 Explosion Proof Motor B5 Flange Mounted to prevent damage during transportation and ensure installation accuracy.
Delivery Time: Leveraging the core logistics advantages of the Pearl River Delta, standard models are shipped quickly, and customized requests are delivered on time according to the contract schedule.
Q1: What's the difference between the B5 and B3 installation methods? How should I choose?
A: B3 is horizontal (with feet), fixed to the ground by foot bolts, and usually connected to equipment via belt or coupling; B5 is a vertical flange, without feet, and the flange at the front of the motor is directly screwed onto the equipment.
Choose B5: If you have a water pump, centrifuge, or are in a confined space and need high transmission efficiency, choose B5.
Choose B3: If you need belt drive, or if you are installing on a flat concrete surface, choose B3.
Q2: Why does the flange of the B5 motor need special protection?
A: The B5 motor relies on the flatness and sealing accuracy of the flange to mate with the equipment. If the flange is damaged or deformed during transportation, it may cause the motor to misalign with the equipment holes during installation, or generate excessive vibration after installation, or even damage the seal of the explosion-proof surface, creating a safety hazard.
Q3: Can this Ex d IIC T4 Explosion Proof Motor B5 Flange Mounted be used in an environment with hydrogen?
A: Yes. This motor has IIC-level explosion-proof certification (Ex d IIC T4 Gb), making it one of the highest-rated general-purpose motors currently available. It is specifically designed for use in highly explosive gas environments such as hydrogen and acetylene. Please use it with confidence.
Q4: Are there any special precautions for maintaining the explosion-proof motor?
The key is to "keep the explosion-proof surface intact."
1. Unauthorized modification is strictly prohibited: Never drill holes or grind the explosion-proof surface on the casing.
2. Regular inspection: Check monthly for aging of the cable seals and for rust on the explosion-proof surface (apply anti-rust oil).
3. Professional operation: Operation must be performed by a certified electrician. Opening the cover while the power is on is strictly prohibited.
