Unique Working Design of 16 Inch Heavy-Duty Gravel Pump

Different from common slurry pumps with narrow impeller gaps, our 16-inch gravel pump adopts a single-stage large-flow open structure, specially optimized for coarse gravel and large-particle solid mixtures.
1. Ultra-wide particle passage The optimized oversized flow channel allows ultra-large solid particles to pass smoothly without crushing, fundamentally eliminating blockage caused by stone jamming. It can handle coarse sand, gravel, pebbles and mixed sediment that ordinary pumps cannot transport.
2. High-volume centrifugal pressurization The large-diameter customized impeller provides strong centrifugal power, realizing super-large hourly slurry throughput and stable high-lift delivery. It maintains high transportation efficiency even under full-load heavy abrasive working conditions.
3. Full wear-resistant structural matching All flow-through parts including impeller, volute, liner and guard plate are made of high-hardness high-chrome alloy. The overall impact resistance and abrasion resistance are greatly improved, adapting to long-term 24-hour continuous heavy-load operation.

Core Advantages of Yuanyang 16 Inch Gravel Pump

1. Large Particle Passing Capacity, True Zero-Clog

This 16-inch gravel pump features an ultra-wide open flow channel structure, supporting super-large particle passage. It can freely transport coarse gravel, pebbles and heavy sediment mixtures, completely avoiding frequent shutdowns and maintenance caused by blockage. It is the preferred equipment for harsh gravel mining and rough dredging environments.

2. High-Chrome Full Wet Parts, Super Wear Resistance

Unlike ordinary pumps that only use partial alloy materials, our 16-inch gravel pump adopts full high-chrome alloy wet parts. The hardness and impact resistance are 3 times higher than ordinary cast iron pumps. It can withstand long-term high-intensity scouring of gravel and abrasive materials, greatly extending the service life and reducing parts replacement costs.

3. Super Large Flow & High Working Efficiency

Professional hydraulic model optimization ensures ultra-large hourly processing capacity. Under the same power configuration, the slurry output is far higher than that of conventional pumps. It perfectly matches large-scale sand mining, dredging and tailings treatment projects, effectively shortening the construction cycle and improving overall project benefits.

4. Stable Long-Distance Transportation Performance

With strong pressurization capacity and stable hydraulic performance, the pump supports long-distance pipeline slurry transportation. It can work stably for a long time without pressure attenuation or pipeline deposition, meeting the requirements of remote sand stacking, tailings discharge and land reclamation filling.

5. Factory Direct High Cost-Performance Flat Replacement

As a professional pump R&D and manufacturing factory, we have no middleman markup or brand premium. Our 16-inch gravel pump achieves import-level heavy-duty performance at half the market price, with lower failure rate and more affordable after-sales spare parts, maximizing profit margins for engineering contractors.
