Introduction: Why Sand Pump Selection Matters in Unloading and Reclamation Projects
Sand unloading, river dredging, and land reclamation projects require highly reliable pumping systems capable of handling abrasive, high-density sand slurry under continuous heavy-duty working conditions. Unlike ordinary water pumps, sand pumps must withstand extreme wear, high solids concentration, long-distance pipeline resistance, and elevation changes such as embankments or reclamation dikes.
Selecting the correct sand pump directly determines:
Project efficiency and cycle time
Fuel or electricity consumption
Pipeline stability and blockage risk
Maintenance cost and service life
Overall project profitability
As a professional manufacturer in the dredging industry, Taian OCEAN Pump Co., Ltd. provides complete engineered sand pumping solutions for global customers engaged in river sand mining, port dredging, offshore reclamation, beach nourishment, and hydraulic filling projects.
With decades of engineering experience, OCEAN Pump designs and manufactures high-performance sand pumps, slurry pumps, dredge pumps, booster pump stations, and complete sand pumping systems for demanding environments worldwide.
Typical Sand Unloading and Reclamation Project Challenges
In real engineering applications such as barge unloading and land reclamation, operators often face complex working conditions:
2.1 High Solid Concentration
Sand slurry concentration can reach 20%–60%, which significantly increases pump wear and energy consumption.
2.2 Long Distance Transportation
Discharge distances range from 100 meters to over 1000 meters, requiring multi-stage pumping or booster pump stations.
2.3 Elevation Differences
Many projects require pumping sand over embankments, river dikes, or coastal protection walls with vertical lifts of 5–20 meters.
2.4 Limited Power Supply
Remote construction sites often lack stable electricity, making diesel engine-driven pump systems essential.
2.5 Abrasive Material
River sand, sea sand, and gravel contain high hardness particles that severely impact impeller, casing, and pipeline life.
3.Engineering Case Study: Jiangxi Yangtze River Sand Backfilling Project
A typical project comes from Jiangxi Province, China, where a customer required efficient unloading of river sand from transport barges into a reclamation area along the Yangtze River.
3.1 Project Requirements
Barge capacity: 1500 tons
Unloading time target: 2 hours per vessel
Discharge distance: 200 meters
Embankment height: 15 meters
Material: Medium to fine river sand
Power limitation: No grid electricity available
This project required a high-capacity diesel-driven sand pumping system with strong head capability and stable continuous operation.
4.Recommended Solution: 300PN Heavy Duty Sand Pump System
After hydraulic calculation of flow rate, pipeline friction loss, slurry density, and elevation head, the recommended solution was the OCEAN Pump 300PN sand pump system powered by a diesel engine unit.

5.Case Study 2: Nanjing Port Sand Unloading and Backfilling Project
Another representative project was completed at Nanjing Port, where fine river sand needed to be transported from barges to a distant reclamation area.
5.1 Working Conditions
Sand handling capacity: 300 tons/hour
Transport distance: 500–600 meters
Embankment height: 8 meters
Operation time: 18–20 hours per day
Barge size: 300-ton vessels

Head: 18 m
Inlet/Outlet: DN150
Power: 22 kW electric motor
Function: Internal sand agitation and extraction
This stage ensures continuous feeding of sand slurry into the main pipeline system.
6.2 Stage Two: Main Horizontal Sand Pump
A high-capacity 300PN sand pump was used for long-distance transportation.
Horizontal Pump Specifications
Flow capacity: 1450 m³/h
Head: 35 m
Pipeline diameter: DN300
Drive system: 260 kW diesel engine
Function: Long-distance sand transfer to reclamation site
6.3 System Performance Results
The combined system achieved:
