1. Efficient Dredging with Vertical Sand Suction Pump
The vertical sand suction pump is extensively utilized for dredging and land filling operations in lakes and rivers. OCEAN Pump’s brand of vertical sand suction pump is specifically engineered to be submerged in liquid for effectively conveying abrasive, coarse particles, dirty water, and particle-contaminated water. Additionally, it’s feasible to integrate multiple vertical sand suction pumps and horizontal sand suction pumps into an operational group to execute sand excavation and digging through hydraulic action.
By employing high-pressure water guns, a high-pressure water column is injected, subsequently impacting the sand. This process humidifies and disintegrates the sand, forming a mixture of mud and water, which is then lifted by a vertical sand suction pump and transported through the pipeline. The vertical sand suction pump boasts high efficiency, favorable overflow conditions, wear resistance, and a long service life. Furthermore, it offers low investment costs, excellent project quality, and remains unaffected by adverse weather conditions during construction.



2. Vertical Sand Pump in Tunnel Mining Projects
Transporting mortar via a grouting truck is a common practice in tunnel mining projects. These trucks are equipped with vertical sand suction pumps to efficiently transport mortar from the tank to the construction site. This setup is widely used in tunnel construction sites across various locations.
Mr. Kim, who primarily operates water pump equipment and serves as an equipment supplier for a local construction group’s project department, had previously purchased a 4-inch vertical sand pump to complement their grouting truck. Following thorough communication, Mr. Kim confirmed the model parameters, specific dimensions, and weight of the 4-inch vertical suction pump.
Upon agreement with the project department, Mr. Kim proceeded to purchase six sets of 4-inch vertical sand pumps from our factory. After the advance deposit was paid, our factory promptly arranged the production plan. Given the tight construction schedule, we expedited the production process and coordinated efforts across the casting, workshop, and assembly departments to ensure timely delivery.
Two vertical pumps were swiftly dispatched to the customer site to meet immediate needs, while the remaining four units were also delivered promptly. The exceptional product quality and attentive service provided by our team instilled trust and confidence in the customer, laying a solid foundation for long-term cooperation.
