A gravel pump is an industrial centrifugal pump specially designed for conveying strong abrasive solid-liquid mixtures containing large solid particles (such as gravel, ore, and slurry).
Main Functions
Continuously transports high-concentration, large-particle, strongly abrasive materials and is suitable for conditions that general slurry pumps cannot handle.
Suitable for harsh environments such as dredging, sand mining, river channel dredging, mining tailings transport, and metallurgical slag transport.
It can be integrated into special engineering devices, such as minimally invasive road slurry disaster management equipment, for suction and discharge of mixtures of crushed stones and liquids.
Core Technical Features
The flow passage is wide and smooth, allowing materials with a maximum particle size of up to 260mm to pass through.
Flow-through components are made of high-hardness wear-resistant materials (such as high-chromium alloy, hard nickel, wear-resistant alloy steel), with hardness ≥58 HRC.
Good anti-cavitation performance, with optimized structure reducing the required net positive suction head (NPSHr).
The discharge direction can be adjusted freely within 360°, facilitating on-site installation.
Various shaft seal types: packing seal, auxiliary impeller seal, mechanical seal, suitable for different working conditions.
Flexible drive modes: V-belt, elastic coupling, gear reducer, hydraulic coupling, variable frequency drive, etc.
