⚠️Important Informations before choosing the right dredging pump :
- Pumps designed for 1450 RPM - Thus higher speed results to higher wear of the wear plates, impeller, casing and agitator.
- Higher RPM results in higher capacity and head.
- To avoid higher wear when pumping abrasive sand RPM should be limited to recomended speed of 1150~1200 RPM.
- Silt and mud may be pumped at higher RPM, because it is less abrasive.
- Our performance curves are based on practical duty points for pumping coarse sand up to 4 mm grain size, providing reliable and realistic expectations in the field.
- Pumping sand through PE-pipes diameter 150, 200, 250mm. Distance up to max. 500 meters.
- There are similar dredging pumps from other manufacturer capable to pump dust of 0,1mm over a distance of 3000 meter.
- Note : Every water pump can pump dust of 0,1mm over a distance of 3000 meter.

Engineering Detail
Key Features
Three engineering pillars that distinguish the HDS 110 from generic submersible pumps — wear resistance, reliability, and ease of maintenance in the field.
Versatile Mounting System
Engineered for fast setup and seamless integration with any dredging equipment configuration.
- Threaded fixations both sides of pump casing — attach jetting ring or EXHYC cutterheads
- Threaded fixations both sides of motor housing — mount on lifting frames, rotating shafts, or ladder arms
- Horizontal or vertical ladder arm mounting — prevents spinning or laying on bottom
- Integrated fixation points for discharge hose, power hoses, and jetting hose
- Operator-friendly design — focus on production, not rigging
Reliability by Design
Built to minimise vibration and survive continuous heavy-duty operation in abrasive conditions.
- Bearings positioned close to impeller — reduced vibration and shaft stress
- 3-blade agitator — superior impact resistance in dense material
- AISI T-431 DIN 1-4057 tempered stainless shaft — outperforms 39NiCrMo3 for seawater
- Diamix shaft sleeve with Nitrile + Teflon seals
- EN-GX260Cr27 wear parts — 27% chrome, 62 HRC — outperforms EN-GJN-HV600 (XCr18)
- Double cartridge seal in oil bath
Easy Maintenance & Repair
Designed for fast overhaul in the field — minimal downtime even in remote locations.
- Extraction bolts for easy dismantling during overhaul
- Over-sized cast part thickness — virtually unbreakable casings
- Dismantle and reassemble in record time
- Pumps can be dismantled without removing attached cutterheads
- Continuous duty rating at low speeds — longer service intervals

Before You Order
Important Operating Notes
Read these before specifying the HDS 110 for your project — they apply to all HDS pumps and affect real-world output.
RPM & Wear Trade-off
Pumps are designed for 1450 RPM maximum. Higher speed = higher capacity and head, but also higher wear on wear plates, impeller, casing, and agitator. For abrasive sand, limit to 1150–1200 RPM to control wear.
Sand vs Silt/Mud
Coarse sand is the most abrasive material — run at recommended 1150 RPM max. Silt and mud are far less abrasive and may be pumped at higher RPM without excessive wear.
Performance Curves
All HDS performance curves are based on practical duty points pumping coarse sand up to 4mm grain size — providing realistic field expectations, not laboratory dust figures.
Beware "Dust" Claims
Other manufacturers publish curves for 0.1mm dust particles over 3000m distances. Any water pump can do this. HDS specs are for real dredging: coarse sand, 4mm grain, max 500m pipeline.
Pipeline Sizing
Use PE pipe Ø150mm, 200mm, or 250mm. Maximum recommended discharge distance is 500 metres. Longer runs require a booster pump — contact HDS for system design advice.
Excavator Requirements
Requires 20-tonne class excavator minimum with auxiliary hydraulic circuit. Operating pressure 242–300 BAR, oil flow 120–135 L/min. Compatible with CAT, Hitachi, Komatsu, Volvo, Doosan, and all major brands.
