Product Introduction

3-Stage Double Output Motor Pump

Model: BJQ-72/0.4B

High-Pressure Dual-Circuit Hydraulic Power Unit for Rescue Tools

The Aolai BJQ-72/0.4B 3-Stage Double Output Motor Pump is a high-pressure gasoline-powered hydraulic power unit designed to provide reliable hydraulic power for professional rescue and emergency response equipment.

Featuring a minimum 3-stage hydraulic pump and a maximum working pressure of 720 bar, the BJQ-72/0.4B delivers stable and powerful hydraulic output for demanding rescue operations.

The double-output configuration allows two hydraulic rescue tools to be connected and operated simultaneously, significantly improving operational efficiency during vehicle extrication, structural rescue, and other emergency response operations.

With a 4.5 L hydraulic oil tank, 3.0 L fuel tank, 20 m × 2 hydraulic hoses, and a continuous operating time of at least 150 minutes, the pump is designed for extended rescue operations in demanding field environments.

Key Features

1. 720 Bar High-Pressure Hydraulic System

The BJQ-72/0.4B provides a maximum working pressure of 720 bar, making it suitable for professional high-pressure hydraulic rescue equipment.

2. 3-Stage Hydraulic Pump

The minimum 3-stage pump design provides stable hydraulic performance and efficient pressure delivery for demanding rescue operations.

3. Double Hydraulic Outputs

The pump is equipped with two hydraulic outputs, allowing two compatible hydraulic rescue tools to be connected and operated simultaneously.

This configuration can significantly improve rescue efficiency when multiple tools are required at the same time.

4. Extended Continuous Operation

With a continuous operating time of ≥150 minutes, the BJQ-72/0.4B is suitable for prolonged emergency rescue operations.

5. Long Hydraulic Hoses

The standard configuration includes:

2 hydraulic hoses

20 m length per hose

25 mm diameter

Safety factor: 4:1

Nominal pressure: 720 bar

The long hoses provide greater operating flexibility and allow rescue personnel to position the power unit away from the immediate rescue area.

6. Gasoline Engine Drive

The pump is powered by a 4-stroke gasoline engine with a minimum power output of 3.6 kW, providing independent hydraulic power for field rescue operations.

7. Manual and/or Electric Starting

The starting system can be configured with manual and/or electric starting, providing flexible operation according to customer requirements.

8. Robust Protective Housing

The pump is protected by a corrosion-resistant metal/alloy housing, providing additional protection for the power unit during demanding field operations.

9. Portable Rescue Power Unit

With dimensions of 900 × 500 × 500 mm and a total weight of 73 kg, the BJQ-72/0.4B is designed as a portable hydraulic power source for emergency rescue teams.
