Explosion-Proof Submersible Sump Pump WQB

Introduction

Explosion-Proof Submersible Sump Pump WQB

Explosion-Proof Submersible Sump Pump WQB is a type of pump specifically designed for safely discharging sewage in hazardous environments containing flammable and explosive gas mixtures such as methane and coal dust.
When the explosive gas mixture inside the explo-sion-proof submersible water and electricity pump motor explodes, the explosion-proof shell should not be dam-aged, and the internal flame should not ignite the explo-sive environment formed by one or more gases or vaporsoutside through the joint surface of the explosion-proofshell. The components that make up the explosion-proofshell shall undergo hydrostatic testing in accordance withGB3836.2-2000 to ensure that they can withstand themaximum internal explosive pressure.
Note: Customized is acceptable.
Application: Explosion-Proof Submersible Sump Pump WQB are used for wastewater discharge in places where combustible gases or vapors form explosive mixtures with air at temperature levels T1-T4 and are classified as lB/C in factories.
