vacuum pump with dc brushless explosion-proof motor

Built-in filters, all-copper air intake, large oil window design and grill-type heat sinks are among the featured designs, which not only improve the durability and safety of the equipment, but also improve the convenience of operation and environmental protection.

Description

Intelligent vacuum pumps are widely used in laboratories, medical equipment, industrial automation, and refrigeration equipment such as air conditioning installation.

Vacuum pump Main features:

  1. DC brushless explosion-proof motor
    Adopting DC brushless motor, it has the features of no spark and no friction, which ensures safe operation in demanding working environments.
    Explosion-proof function: avoiding sparks or arcs, it is suitable for flammable and explosive environments, improving equipment safety.
    High reliability: brushless motor is not affected by brush wear, smooth operation, low maintenance cost, and long service life.
  2. Integrated cylinder design, built-in solenoid valve and vacuum gauge
    One-piece cylinder: integrated design reduces parts connection, compact structure, and reduces air leakage and failure points.
    Built-in solenoid valve: accurately controls the suction and discharge of the vacuum pump to ensure stable operation.
    Built-in vacuum gauge: real-time monitoring of the vacuum level, ensuring the vacuum status of the system is always within the set range.

Vacuum pump Functional features:

  1. Built-in filter mesh, filter oil mist, reduce pollution
    Oil mist filtration: Built-in high-efficiency filter can effectively filter oil mist, keeping the pump and environment clean, especially suitable for non-polluting environments such as medical and laboratory use.
    Environmental protection: reduces oil mist emissions, maintains a clean working area, and protects the environment and equipment from oil mist pollution.
  2. Full copper air inlet, strong and durable
    High-strength material: All-copper air inlet is wear-resistant, corrosion-resistant, can withstand long-term and high-frequency work, and reduces wear.
    High temperature and oxidation resistance: Copper material has excellent thermal conductivity and oxidation resistance, ensuring stable work in high temperature environments and extending service life.
  3. Large oil window design prevents oil shortage and enables timely refueling
    Oil level monitoring: The large oil window design allows users to observe the oil level in real time, avoiding overheating or damage caused by lack of oil.
    Timely refueling: Users can refuel as needed based on the oil window marking, protecting equipment operation and avoiding mechanical damage.
  4. Grid type heat dissipation port, effectively protects machine performance
    Optimized heat dissipation design: The grille type heat sink improves air flow efficiency, enhances heat dissipation, and prevents pump body overheating.
    Protects motor performance: The heat dissipation design reduces temperature buildup, preventing high temperature damage to the motor and components, thus extending the equipment’s service life and ensuring stable long-term operation.
