Gear Pump & Explosion-Proof Motor Set


Applications (for Explosion-Proof Motor):

Hazardous environments with explosive gas or vapors should adopt a explosion-proof motor to prevent explosion or fire hazard which cause substantial damages to people and properties. Some examples of these dangerous environments include:

1. Places with flammable gas or liquid stored inside concealed machineries or containers. In the event of sabotage, operating error or omissions, the explosive gas or liquid can leak to inflict danger;
2. Places similar to (1) listed above but equipped with ventilation device to prevent gas explosion. Again explosive gas leakages can occur when the ventilation device malfunctions;
3. Places close to (1) and (2) above where dangerous levels of explosive gas are present or are likely to get inside.

Features (for Explosion-Proof Motor):

- This explosion-proof motor conforms to the stringent Taiwan's National Standards (CNS). Its design is aimed at eliminating any unusual sparks, electric arcs or over-heating which can occur in wire wrapping, stator and various other places inside the motor. This highly precise and reliable motor greatly enhances operational safety.
- Design of the motor's fan housing conforms to European Union (EN294) requirements. Another assurance on its durability and product safety.
- Built using heat and chemical tolerant insulative material for improved safety and longer useful life.
- Under the requirement of revised CNS, the motor's specifications comply with IEC international standards for better interchangeability and easy of install.
- Taps complying with BS 4999 specifications are included for better flexibility and convenience of use.
