The diesel driven centrifugal slurry suction pump, also known as the gravel pump, large particle sand pump, or big particle sand suction pump. Under the OCEAN brand, it is constructed using high-quality and highly wear-resistant materials. It is specifically designed and manufactured for the extraction and long-distance transportation of large particles such as pebbles, small stones, and river debris, with a maximum passing particle size of up to 240 mm. The OCEAN brand centrifugal sand suction pump boasts wear resistance, corrosion resistance, high sand absorption efficiency, large overcurrent particle capacity, and excellent cavitation resistance. Currently, the slurry suction pump finds extensive application in reservoirs, lakes, seas for the transportation of large particles, river dredging, and various other working conditions.
Additionally, the centrifugal slurry suction pump is utilized in dredging, gravel and pebble suction, as well as in mining and metal smelting waste slag transportation. How to choose diesel driven centrifugal slurry suction pump for Qingzhou China market? What’s it design and parameters? In this text, we will give you guidance about that.



1. How to choose a diesel driven centrifugal slurry suction pump for Customers from Qingzhou?
Recently, a customer from Qingzhou expressed interest in purchasing a centrifugal diesel engine slurry suction pump for their sand suction dredger. Tai’an OCEAN Pump has numerous sets of slurry suction pumps operating in that area. When customers send inquiries, we provide comprehensive dredging solutions. In March 2020, a shipyard customer signed a river dredging project contract. The working site featured an 8-inch discharging pipeline spanning approximately 300m, with various garbage and stones present in the target river.
Following communication between our engineers and the shipyard personnel, our engineer recommended opting for the 8-inch centrifugal diesel engine slurry suction pump ZS200 to collaborate with the existing pipeline for construction purposes. This pump’s casing, impeller, and guard plate are crafted from high-chromium wear-resistant alloy material. Furthermore, the impeller flow channel was redesigned by our technician to enhance particle passing capability. Currently, the pump can accommodate stones up to 120 mm in size, thus averting flow channel blockage caused by pebbles and preserving sand pumping efficiency.
2. How does customer selected OCEAN Pump’s diesel driven centrifugal slurry suction pump?
During discussions, the customer inquired extensively about the wear resistance and replacement schedule of the centrifugal sand suction pump. After reviewing the construction videos of our products, the customer compared pump types from other companies and concluded that our large-particle sand pump’s transportation distance meets requirements and offers superior wear resistance. Consequently, the customer signed a purchase contract with our company on the same day. Upon receiving payment, we committed to delivering the centrifugal diesel engine slurry suction pump to the shipyard within 7 working days as per the contract.
3. What are the designed parameters of the diesel driven centrifugal slurry suction pump?
- Flow capacity: 500m3/h
- Head- 25m
- Speed-1500rpm
