China Explosion Proof Sewage Pump Suppliers Manufacturers Factory

Product Details

Explosion proof sewage pumps are suitable for chemical, petroleum, pharmaceutical, mining, paper industry, cement plants, steel mills, power plants, coal processing industries, and urban sewage treatment plant drainage systems, municipal engineering, construction sites and other industries to transport sewage and dirt with particles.

Features:

1. The explosion proof sewage pump adopts a unique single-piece or double-blade impeller structure, which greatly improves the dirt passing ability, and can effectively pass 5 times of the fiber diameter of the pump and the solid particles with a diameter of about 50% of the pump diameter.

2. The mechanical seal of the equipment adopts a new type of hard and corrosion-resistant titanium tungsten carbide material, which can make the pump run safely for more than 8000 hours.

3. The overall structure is compact, small in size, low in noise, and remarkable in energy saving effect. It is easy to overhaul, no need to build a pump room, can work in submerged water, greatly reducing the project cost.

4. The pump sealing oil chamber is provided with a high-precision anti-interference water leakage detecting sensor, and a thermal element is embedded in the stator winding to automatically protect the pump motor.

5. It can be equipped with automatic control cabinet according to user needs, and automatically protects the pump from water leakage, leakage overload and over-temperature, which improves product safety and reliability.

Use conditions:

◆ The temperature of the pump medium does not exceed 60 ° C, the medium weight is 1-1.3 kg / dm3, and the PH value is in the range of 5-9.

◆ The pump has no internal self-flow circulating cooling system pump, and the motor part does not exceed 1/2 of the liquid level.

◆ The main parts of the explosion-proof sewage pump are cast iron, so it cannot be used to pump highly corrosive liquids.
