High-Performance 4-Inch Sand Mining Centrifugal for Efficient Operations Pump

Multi-groove pulley on top, matched with single-cylinder diesel engine or 3-phase motor; work independently off-grid, ideal for water well drillers and river dredgers

High-chrome wear-resistant impeller & pump casing, durable for sand-laden muddy water

Alloy cast pump housing & impeller resist abrasion from sand, gravel and silt; service life over 3 times longer than clean water pumps.

Wide square suction port without narrow dead space, smoothly pass straw, gravel and thick silt to avoid pump blockage, stable sand pumping efficiency.

Extended vertical shaft design, allow semi-submerged operation in mud ponds and shallow rivers

Long vertical barrel structure, only pump head submerged in water; maintenance and moving without diving, safer operation.

Split flange assembly, fast replacement of wearable parts

Pump body and barrel connected by flange bolts; impeller and seals can be taken out easily without full disassembly, low on-site maintenance cost.

Full cast iron with anti-rust paint coating, anti-corrosion for outdoor use

Thick integrated cast iron construction with internal & external anti-rust paint, resist acid & alkali mud corrosion for long outdoor service.
