Case Description

A large-scale river desilting project was carried out in a city with the aim of improving the water quality and flood control and drainage capacity of the river. The dredging process produces a large amount of slurry, which needs to be transported to the designated sludge disposal site in a timely manner. The centrifugal pumps used in the past had serious impeller wear and frequent failures when conveying river slurry with high concentration and large particles. At the same time, the head of the centrifugal pump was limited, making it difficult to meet the demand for long-distance transportation, resulting in low slurry transportation efficiency and slow progress of the dredging project.

Solution

The construction team brought in eight high-flow Rotary Lobe Pump from Bonve. These Rotary Lobe Pump have a strong conveying capacity and can easily cope with high concentration and large particles of slurry, and the head can be customized according to the actual demand. The unique design of the over-flow components effectively reduces the wear and tear of the slurry on the pump body and extends the service life of the equipment.

The equipment supplier follows up the installation and commissioning of the equipment and provides on-site technical support. After the introduction of Rotary Lobe Pump, the slurry conveying efficiency increased by 5 times, and the number of equipment maintenance was reduced from 3-4 times per week to less than 1 time per month, which guaranteed the smooth progress of the river dredging project, greatly shortened the construction period, and made the water quality and ecological environment of the river channel get rapid improvement.
