The sand dredging pump is a high-efficiency centrifugal pump. Based on the company's ZJ sand and slurry pump series, it integrates the advantages of similar products with self-innovation, focusing on energy efficiency and wear resistance. The pump adopts an optimized hydraulic design to minimize energy consumption while handling abrasive sand slurries. The castings conform to the EN 10204/3.1 certification. Surface inspection and non-destructive testing meet the DIN1690 Class 4 standard.

Sand filling projects for land reclamation.
FAQ
Q: How does the pump handle different sand particle sizes?
A: The pump is designed for sand particles up to 50 mm. For finer sand (≤2 mm), we recommend our ZL light-duty slurry pump variant with higher efficiency; for coarser sand (50-80 mm), the ZG gravel pump series is more suitable.
Q: What is the recommended maintenance schedule for continuous sand dredging?
A: Routine maintenance includes checking wear parts every 900 hours, replacing lubricating oil every 1500 hours, and inspecting the mechanical seal every 1800 hours.
Q: Can the sand dredging pump be used in saltwater environments?
A: Yes, we offer a corrosion-resistant version with 304 stainless steel components for coastal sand dredging, which resists saltwater corrosion for 3-5 years with proper maintenance.
