• Restoring aquatic habitats and ecosystems.

 

 

What is the depth of dredging?
The dredging depth depends on project requirements, maritime needs, and environmental considerations. Dredging depths can range from shallow areas to deeper channels.

 

What is the cost of dredging?
Dredging costs vary depending on project size, duration, location, equipment, and disposal methods. For large-scale projects, they can range from thousands to millions.

 

How is dredging quantity calculated?
Dredging quantity is calculated based on factors such as the volume of material, dredging depth, and sediment density. Hydraulic calculations and survey data estimate the amount of material to be removed.

 

What are the two main types of dredging?
The two main types of dredging are hydraulic dredging and mechanical dredging. Hydraulic dredging uses water jets or suction to excavate sediment, while mechanical dredging uses buckets, scoops, or cutting devices to remove material.

What to bear in mind before buying a pump

Naipu® factory of slurry pump , gravel sand pump , dredging pump and spare parts.

There's much to consider before buying a pump.

Anyone wanting to buy a new pump for their water logistics system will need to answer a lot of questions first before the manufacturers choose the suitable pump Model.

Here is a brief overview of what to expect:

What should be pumped?

This is a fundamental question. Pumps cannot pump all fluids. What medium the slurry pump transport ? Used in which industry ? like gold mining , iron mining , or river sand pump suction? Or others industry . The Slurry Density ? the Solid Concentration? Corrosive or not ?

What pumping volume?

The water volume that needs to be pumped (l/min or m³/h) is usually the factor that dictates the required pump output. Each pump covers one range and has an optimum, which is why there are so many types &#; for instance, Naipu has more 30 model pumps . Naipu Slurry Pump can reach 5-m3/h. Don&#;t forget to take into account the diameter of any pipes through which the pumped volume needs to pass.

How high can the medium be pumped?

This question is linked to the previous one because the pumping volume will decrease the higher it is pumped. The main factor here is the absolute height difference between the lower and upper water level (geodetic head). High pressure pumps can pump up to more than 100 m. The same thing also applies if, instead, the horizontal distance is very large. If possible , could you please try to draw a sketch drawing about how you plan to install the pump , transport from where to where ? the horizontal tansport distance ? the vertical height? so that our engineer can calculate the exact head required. , Tip: Sometimes two (identical) pumps can be operated in series if an adapter is used &#; the second pump acts as a booster and almost doubles the output. 

Does snoring occur?

This is what experts refer to when not only water, but also air, is suctioned in; for instance, at removal points where the water level is (too) low in some cases. This is critical for many pump motors because they will overheat very quickly without any water to cool them. Tip: Ensure that the pumps have a dry-run protection feature &#; this will allow them to withstand this torture.

Does the water volume vary?

If the pump is required infrequently, pumps with permanently attached level sensors are the solution because they switch on and off automatically. Electrode sensors are much more reliable than mechanical contact switches. Alternatively, an external control unit can be used. Tip: Frequency converters ensure a gentle start-up, prevent pressure surges and balance out multi-pump systems. 

Electrical connection?

There are pumps for almost all capacity ranges. The higher the range, the higher the connected load needs to be, and an appropriate connection on site is required. Often the (high!) start-up current of the pump is not taken into account, especially when a power set is used. Most pumps are operated in in three phases .

Naipu Slurry Sand Pump can be drived by Motor or diesel. We can help to calculate the Motor power required.

Installation and operation?

Some pumps may only be installed in a dry environment in the pumping station. In contrast, submersible pumps are operated whilst submerged in the medium. The maximum submersion depth is stated in the data sheet. Some can even be mounted in a dry environment. Just ask if they are suitable for permanent operation. Tip: Ensure that the pump has a centrifugal oil lubrication system because these will work perfectly in either horizontal or vertical installation positions.

Should I carry out the maintenance work myself?

Anyone seeking to save money can carry out the most common maintenance tasks themselves on site, thereby ensuring that there are no downtimes because the pumps do not have to be returned to the manufacturer for servicing. Therefore, it is always a good idea to opt for modular pumps.

Naipu Pump is easy to maintenance , and we also can help you to do so and reduce the downtime.

Summary

It is advisable being well prepared when you talk to pump experts, because having the information about the application and local environment at your fingertips will speed up the process considerably.

And then there is the question of the delivery time. This might be decisive because there are only few manufacturers that have large stocks of pumps - most usually produce to order.

anyone who does not know the needs exactly can experiment before investing.
