How to Save Money When Buying Marine Dredging Pump wholesale

Tip 1. Stay close to the Best Efficiency Point of the pump.

As mentioned before, mobile pumpsets are oftentimes overlooked regarding cost-effectiveness. However, it is possible to save considerably by starting with the selection of a pump based on the Best Efficiency Point (BEP)(Helmreich, ).

Example: A temporary pumping system requires a duty point of 350 m³/h at 28 mwc. There are two different diesel driven pumps available that can be deployed for this job. A

The BA150E is spot-on at BEP with a pump efficiency of 80 percent; with a required power of 33 kW the fuel consumption will be 9 litres per hour. With the same duty point, the BA180E operates to the left of BEP with a pump efficiency of 68 percent. As a result, the required power is 39 kW and the fuel consumption is more than 1,5 litres per hour higher.  

'Selecting a centrifugal pump on BEP will also have a positive impact on the life span of the pump and reduces maintenance costs.'

There are two different diesel driven pumps available that can be deployed for this job. A BA150E D285 needs to run at rpm and a BA180E D328 can do it at rpm. By comparing both performance curves it becomes clear that the BA150E is the best choice for this duty point.The BA150E is spot-on at BEP with a pump efficiency of 80 percent; with a required power of 33 kW the fuel consumption will be 9 litres per hour.

Dredge Pump For Dredger

Sent to Ghana

Cutter Suction dredger is mostly used in landfilling projects .which is suitable for excavating sandy soil, silt, and other loose river bottoms. Because of the high price of sand dredgers, so many clients or shipbuilding companies choose to use our sand dredge pump set to make dredgers by themselves.

Dredge Pump For Dredger

set as the main part of the cutter dredger with high roles for dredging.
It decides the sand output and the discharge distance.

The customer chose the WEICHAI Brand engine as the driving power and also use the gearbox to make rotation speed changes.
 

 

The customer said why he has been cooperating with us because he bought a 10-inch sand pump dredger from us in , which brought him a lot of wealth. At the same time, because it has been in operation for 6 years, he wants to change to a larger one. He came to work, but due to the impact of the epidemic and the economic situation is not good, he also wanted to save money, so he bought the steel-welded dredger hull locally. We were very moved after hearing this. I really thank him for believing in us for so many years.

18 days after payment, all the goods were produced. We ordered the container and sent it to Tema in Ghana. We hope that the customer can complete his sand pump dredger soon after receiving it.
