BEd201/12 Series Explosion-Protected Electro-Hydraulic

BEd201/12 series is an explosion‑protected, wet‑type electro‑hydraulic thruster (also called electro‑hydraulic pusher), used as a safe driving and releasing device for industrial drum brakes, wheel brakes and other braking mechanisms in hazardous environments.

Basic Identification

Model: BEd201/12 series

Type: Explosion‑protected electro‑hydraulic thruster

Protection: Explosion‑proof construction for gas / dust hazardous areas

Application: Actuation and release of spring‑applied brakes

Key Parameters

Rated thrust: 2000 N

Working stroke: 120 mm

Power supply: Three‑phase AC 380 V, 50 Hz

Explosion‑proof grade: Ex d II CT4 / DIP A21 TA, T4 (typical)

Protection class: IP65

Insulation class: F

Working Principle

When powered on, the explosion‑proof submersible motor drives the impeller to produce hydraulic pressure, extending the push rod to release the brake.When power is cut off, hydraulic pressure dissipates; the return spring retracts the push rod, allowing the brake to engage automatically.The fully enclosed, explosion‑proof structure ensures safe and stable operation in flammable, explosive or dusty environments.

Features

Special explosion‑proof design for hazardous locations

Stable thrust, smooth action, low noise

High sealing performance, long service life

Suitable for frequent operation

Compatible with YWZ9B, BYWZ series explosion‑proof brakes

Applications

Coal mines, oil fields, chemical plants, gas stations

Port and metallurgical machinery in explosion‑hazardous areas

Cranes, hoists and conveying equipment requiring explosion protection

Short version 

BEd201/12 series explosion‑protected electro‑hydraulic thrusters are hydraulic pushers with 2000 N thrust and 120 mm stroke, used for safe brake actuation in flammable and explosive industrial environments.
