Gravel Pump (also known as a sand and gravel pump) is a centrifugal impurity pump specifically designed to transport strongly abrasive solid-liquid mixtures containing large solid particles (such as gravel, ore, slurry, etc.). Its core design objective is to meet the continuous transport requirements of coarse particles, high wear, and high concentration materials that ordinary slurry pumps cannot handle.
Core Features
Structure Type: Usually horizontal, single-stage single-suction, cantilever type, single pump casing structure, with clamp or hoop connections between pump casing and pump cover. The discharge direction can be adjusted within a 360° range.
Flow Component Material: Commonly uses high-hardness wear-resistant materials, such as high-chrome alloys, hard nickel, or wear-resistant alloy steel, with a hardness of not less than 58 HRC.
Flow Channel Design: Wide flow channels, capable of passing particles with diameters up to 178–260mm, optimized for cavitation performance, suitable for large particle transport.
Sealing Type: Optional packing seal, expeller seal, mechanical seal, or combination form.
Drive Method: Supports various methods, including V-belt, flexible coupling, gearbox, hydraulic coupling, and variable frequency drive.
Lubrication Method: Bearings mostly use grease lubrication, with some models supporting oil lubrication.
