Gravel Pumps

Heavy-Duty Pumps for Sand, Gravel & Large Particle Slurries

SMI’s G/GH Sand & Gravel Pumps are specifically engineered to handle highly abrasive slurries containing large solids and coarse particles. Designed for demanding dredging, mining and aggregate applications, the G/GH Series combines heavy-duty construction with exceptional wear resistance and reliable hydraulic performance.

The single casing design, oversized flow passages and flexible discharge configuration make these pumps ideal for transporting sand, gravel, dredged material and other highly abrasive slurries under challenging operating conditions.

Key Features

  • Heavy-Duty Single Casing Construction
  • Wide Flow Passages for Large Solids
  • 360° Adjustable Discharge Orientation
Advantages

Advantages of the G/GH Sand & Gravel Pump

The G/GH Series is purpose-built for handling coarse, abrasive materials where conventional slurry pumps are unable to perform efficiently.

Heavy-Duty Single Casing Design

The pump features a robust single casing construction secured with clamp bands, allowing quick access for inspection and maintenance while providing exceptional structural strength for demanding applications.

Wide Wet-End Passages

Large internal flow passages enable the pump to handle oversized particles and highly abrasive slurries with reduced risk of blockages, making it ideal for dredging, sand and gravel transport.

Flexible Installation

The discharge outlet can be positioned in any of eight directions (360° rotation), providing greater flexibility during installation and simplifying integration into existing pumping systems.

Exceptional Wear Resistance

Critical wet-end components are manufactured from premium high chrome and Ni-Hard wear-resistant alloys, delivering excellent abrasion resistance and extended service life in aggressive operating environments.

Excellent Suction Performance

Designed with favourable Net Positive Suction Head (NPSH) characteristics, the G/GH Series maintains stable performance even under demanding suction conditions, improving reliability across a wide range of applications.

High Head Capability

The GH models are specifically engineered for higher head applications where greater discharge pressures are required, making them suitable for long-distance slurry transport and demanding pumping duties.
