Customer Witness

Defying Sri Lanka's Coastal Challenges

Ayubowan! Our engineering team has been working along Sri Lanka's coast for years, where traditional slurry pumps often fail due to monsoon silt and saltwater corrosion. Last year, during the Colombo South Port Expansion Project, we tested the RAY hydraulic dredging pump—and the results exceeded all expectations!

Its hydraulic drive system maintained stable discharge even in 30-meter-deep silt (density 1.6t/m³), with 40% lower energy consumption than diesel pumps, significantly easing cost pressures from CEB power shortages. What amazed us most was the salt-corrosion-resistant coating—the pump operated flawlessly for 6 months in saline conditions without rusting, unlike other brands that required seal replacements every 2 months!

Maintenance became effortless: local technicians can now replace wear parts in 30 minutes using a toolkit, eliminating delays from overseas spare parts shipments. We’ve already ordered a second batch for the Jaffna Salt Lake Development, proving its reliability across diverse projects.

Bohoma istuti! RAY’s equipment isn’t just machinery—it’s a steadfast partner in Sri Lanka’s infrastructure, enabling us to deliver projects on schedule through monsoons and salt spray!

Excavator Dredge Pump Advantages

This pump can handle solid matter with a maximum particle size of 150mm, and the solid-liquid extraction concentration can reach more than 70%. Due to different working conditions, the output of the pump may also vary depending on the medium being processed, on-site operations, transportation distance, and other factors.

This device is mainly installed on the excavator. The power is provided by the hydraulic station of the excavator, which can realize free transition. The power source is a diesel engine, which can solve the problem of inconvenient power during construction in remote areas.

Flow parts: pump casing, impeller, guard plate, and stirring impeller are all made of high chromium alloy. Other materials can be customized.

Use a unique sealing device to avoid frequent replacement of mechanical seals and improve work efficiency.

Excavator Dredge Pump FAQ

What are the precautions for using hydraulic dredging pumps?

1. Ensure that the system hydraulic oil is pure, less impurities, and has good lubricity, compatibility and stability.

2. According to the existing hydraulic system pressure, displacement, efficiency, etc., the silt pump should be reasonably equipped so that the system can operate normally and the system should not be overloaded for a long time.

3. When used with an excavator, the excavator arm should move lightly and slowly. It is strictly forbidden to knock or smash it hard under harder working conditions to avoid damaging the pump body.

4. Select hydraulic oil pipes of standard specifications, use the specified bolts and tighten them with the specified torque. Unqualified installation will cause malfunctions, damage or oil leakage.

5. When the equipment is transferred, the hydraulic oil port should be kept clean to prevent impurities from entering, etc., which will affect the normal service life of the motor.

6. It is prohibited to modify or disassemble the equipment without permission, otherwise it will not operate normally or abnormally.
Compared with electric submersible sand pumps, what are the advantages of hydraulic dredging pumps?

1. Hydraulic drive offers low motion inertia and rapid response, enabling stepless speed regulation across a wide range.

2. It provides automatic overload protection, eliminating the risk of motor burnout.

3. It can handle media with high solid concentrations (up to 70%+), such as mortar, sediment, and slag.

4. When connected to hydraulic-powered equipment like excavators, it allows for flexible site relocation—a distinct advantage in remote areas with insufficient power supply.

5. As an attachment for excavators, it can suction and transport materials over long distances in scenarios where direct excavation is challenging, enhancing the excavator’s operational versatility.
How to choose the right model?

1. What is the tonnage of your excavator?

2. What is the medium, concentration and particle size that you need for dredging pump?

3. What is the horizontal distance and height of the medium transported by the dredging pump?
How does a Hydraulic Dredging Pump work?

Powered by a hydraulic system, the pump uses a motor to convert hydraulic energy into mechanical motion. Mixing devices on both sides agitate settled sludge, while blades direct solids toward the suction inlet. A unique sealing design ensures reliable mechanical seals and a longer lifespan, with hydraulic drive enabling stable operation in harsh conditions.
What is a Hydraulic Dredging Pump?

A hydraulic dredging pump is a hydraulic machine with mixing functions that features high-quality materials, advanced design, and strong particle-handling capability. It conveys media with solid particles (sediment, coal cinder, tailings, etc.) and is ideal for dredging in mining, power plants, water treatment, ports, and rivers, as well as hydraulic filling in beach/coastal construction. It replaces traditional mud pumps, working flexibly with excavators/loaders for easy relocation, especially in remote areas without power constraints.
