QBG Large-Flow Mining Pneumatic Diaphragm Pump

1.No Overheating: Driven by compressed air, the pump cools during operation due to the expansion of exhaust air, eliminating harmful emissions.

2.Spark-Free Operation: Uses no electricity and is grounded to prevent electrostatic sparks.

3.Particle-Handling Capability: Positive displacement action with ball valves resists clogging from solids.

4.Low Shear Force: Gentle suction and discharge minimize agitation, ideal for shear-sensitive materials.

5.Adjustable Flow: Flow rate can be regulated via a throttle valve at the outlet.

6.Self-Priming: Capable of automatic priming without external assistance.

7.Dry-Run Safe: Operates safely without fluid for short periods.

8.Submersible: Suitable for underwater applications.

9.Wide Fluid Compatibility: Handles viscosities from low to high, including corrosive and viscous media.

10.Simplified Control: No complex electronics, cables, or fuses required.

11.Portable Design: Compact and lightweight for easy relocation.

12.Maintenance-Free: No lubrication needed; leak-free operation prevents contamination.

13.Consistent Efficiency: Maintains performance even under wear.

14.Energy-Efficient: Automatically stops when the outlet is blocked, preventing overheating or damage.

15.Leak-Proof: Sealless design eliminates leaks and dead spots in operation.

16.Advanced Air Valve: Dead spot-free operation with anti-icing exhaust ports.
