FAQ

  • Q What are the precautions for using hydraulic dredging pumps?

    A
    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.
  • Q Compared with electric submersible sand pumps, what are the advantages of hydraulic dredging pumps?

    A
    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.
  • Q How to choose the right model?

    A
    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?
  • Q How does a Hydraulic Dredging Pump work?​

    A 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.
  • Q What is a Hydraulic Dredging Pump?​

    A 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.​
  • Q What does a skid steer/excavator mulcher do?

    A Skid steer mulcher attachments cut down and grind up brush, trees, and stumps with ease. You'll see these mulchers at work on construction sites, farmland, disaster sites, and landscaping projects. Anywhere that trees and brush need to be cut and cleared, skid steer mulchers become a valuable tool. They make quick work out of an otherwise tough job—toppling trees, munching through stubborn vegetation, and clearing land as efficiently as possible.
  • Q How does a skid steer/excavator forestry mulcher work?

    A To create mulch, skid steer mulchers use durable metal teeth that grind brush down into smaller pieces. They come in two types: Disc mulchers and Drum mulchers.
  • Q How much do skid steer/excavator mulchers cost?

    A SKID STEER MULCHER/EXCAVATOR COSTS & OPTIONS. Disc mulcher skid steer attachments are less expensive. RAY mulchers fall into a $4000-$16000 price range and have a 36'', 48'', 60'', 72'', and 84'' cut width.
  • Q What size skid steer do I need for a mulcher?

    A To run a mulcher, you'll need a 10-45 GPM hydraulic output, and the operating pressure caps out at 4,200 psi.
  • Q When should you use a forestry mulcher?

    A A forestry mulcher is a go-to attachment when your goal is to clear land quickly. It is designed to topple and grind logs, trees, and thick brush. Keep in mind, however, that these attachments should be considered advanced forestry equipment.
  • Q What pipeline is connected to the pile breaker on the excavator?

    A Connect the hydraulic oil line of bucket cylinder of the excavator to the oil line of the pile breaker's cylinder through the balance valve.
  • Q The cylinder will damaged when we use pile breaker?

    A It does not affect the cylinder because our structure is different from other suppliers. Our reaction force acts on the flange, not the cylinder.
  • Q Vulnerable parts of Pile Breaker

    A Pin & Chisel : Normally, our chisel don't need to be changed as long as the worker operate in properly.
  • Q What's the material of chisel? How much service life?

    A Warranty is 12 months except wear parts( Elastic pin & Chisels, Chisel service life is around 10,000 time). But you should operate it in correctly.
  • Q What is a hydraulic breaker on a excavator?

    A A breaker is a powerful impact hammer mounted on an excavator or skid steer for the demolition of concrete structures or rock. It is powered by the excavator/skid steer's auxiliary hydraulic system, which is equipped with a foot valve for this purpose.
  • Q How do I choose a hydraulic breaker?

    A Instructions for choosing a hydraulic breaker from a variety of models and brands. 1. Weight of the basic machine. The hydraulic breaker should not exceed 10% of the weight of the base machine. 2. Oil flow rate. ... 3. Working pressure. ... 4. Productivity. ... 5. Construction. ... 6. Ease of use and maintenance ... 7. External noise and vibration.
  • Q Which rock breaker is best?

    A For hard materials, we recommend a 7,500 to 10,000 ft-lb breaker, and if high production is required a 13,500 ft-lb breaker would be beneficial. CONCRETE BREAKING: When breaking concrete, the hammer must penetrate the material so that it cracks and separates from the reinforcing steel.
  • Q What's the principle of hydraulic breaker?

    A The piston is moved by the high and low pressure of the hydraulic oil to hit the chisel, and then the chisel hits the stone for crushing work.
  • Q What's the different among three models breaker?

    A
    Top Type: 1. easy to locate and control 2. More conducive to excavator 3. Weight lighter, the lower risk of broken chisel 
    Box Type: 1. Reduce noise 2. Protect the enviroment 
    Side Type: 1. Overall length shorter 2. Hook back things conveniently 3. Maintenance free
  • Q What's main parts of hydraulic breaker? And how about their fundation?

    A
    Cylinder: This contains the moving piston which strikes the tool. The seals for both ends of the piston are also located in the cylinder. The seals for the upper end of the piston are located in a removable seal retainer while the seals for the lower end of the piston are located in proves machined directly into the cylinder. 
    Piston: The piston transfers impact power to the tool, generated by hydraulic power. 
    Front head assembly: This retains the tool, using the tool pins. By removing these pins, the tool can be changed.
    Ring Bush: This guides the tool, Ring Bush limits the uppermost position of the tool. It is consumable parts, which should be checked for wear limits. If needed, they should be replaced. 
    Back head assembly: This contains the cushion chamber charged with N2 gas that is compressed during upward strokes of the piston, and serves to provide maximum absorption of the piston recoil, efficiently storing this energy for the next blow. 
    Through bolts: These are used to assemble the front head, the cylinder, and the back head. They have to be constantly tightened to the specified torque. Inspect the bolts for loosening, and re-tighten them weekly.
