Standard Across All Models
Shared Specifications
Every HDS pump is built on the same engineering platform — same wear material, same shaft grade, same mounting system. What changes is power and hydraulics.
Wear Parts Material
EN-GX260Cr27 — 27% chrome cast iron, 62 HRC hardness. Extreme abrasion resistance for sand and gravel.
Pump Shaft
AISI T-431 stainless steel — seawater and marine-grade corrosion resistance for all environments.
Shaft Sleeve
Diamix ceramic-reinforced sleeve for maximum sealing life and reduced shaft wear under abrasive slurry.
Max Operating Pressure
430 BAR — robust hydraulic circuit rated for high-demand excavator hydraulic systems.
Max Grain Size
4 mm maximum grain passthrough on standard impeller. Vortex suction design prevents clogging.
Mounting System
Universal HDS frame — fits all excavator boom arms. Horizontal or vertical shaft orientation. Quick-change brackets for discharge and suction pipe.
Hydraulic Drive
Axial piston hydraulic motor. Direct drive, no gearbox, no belt. Compatible with any excavator hydraulic system.
Suction Options
Standard suction strainer OR suction pipe connection. Threaded mounting points on both sides of vortex casing for agitators, mixers or cutterheads.
Engineering Details
Design Philosophy
Developed by field engineers with real jobsite experience. Every decision prioritises uptime, serviceability and operator safety.
01
Non-Round Profile
Unlike cylindrical competitors, the HDS rectangular cross-section is easy to grip, chain and orient. No rolling on deck, no struggle adapting to existing machine geometry.
02
Discharge Pipe Clamp
Integrated threaded clamp on motor housing allows fixing the discharge pipe directly to the pump — operator keeps focus on dredging, not on pipe management.
03
Self-Cleaning Agitator
Side-mounted agitator with self-cleaning blades ejects oversized material away from the suction inlet. Prevents blockage without stopping the pump — ±125 m/min circumferential speed.
04
Anti-Rotation System
Horizontal or vertical shaft fitting to the excavator ladder arm prevents unit rotation in operation — no twist, no pipe stress, no production loss.
05
Suction Pipe Option
Designed from the start to accept a suction pipe in place of the standard strainer — enabling deep dredging through combi wall sheets, harbour walls and confined piling.
06
Vortex Casing Ports
Threaded mounting points on both sides of the vortex casing accept: jetting rings for hard clay, agitators for heavy silt, or cutterhead connectors for rock dredging.
