GHP and GHPP High-pressure Gravel Pumps

Engineered for extreme high-pressure slurry handling, the GHP/GHPP series deliver superior performance in highly abrasive environments. Built upon the proven GH platform, these pumps incorporate reinforced high-pressure plates to withstand continuous operation with large-particle slurries (up to 203 mm), minimizing downtime and total cost of ownership.

Key Features of GHP and GHPP High-pressure Gravel Pumps

Advanced Materials: High-chrome A05, A61, and A14 alloys (≥26.5% Cr, ≥60 HRC) provide 3–5x longer service life than standard steel pumps.
High-Pressure Ratings: GHP handles up to 2,500 kPa for coal refuse backfill; GHPP operates at 2,100 kPa for iron ore tailings.
Optimized Hydraulics: CFD-enhanced impeller and 4-vane closed design ensure efficient flow and superior solids handling.
Robust Construction: Unlined, all-metal body with reinforced casing and optional auto vacuum priming for reliable high-pressure performance.
Low Maintenance Design: Grease-lubricated bearings, removable shaft sleeves, and split release collars simplify servicing and extend operational life.
Seal Options: Gland packing, expeller, or mechanical seals.
