NMG(GH) Series Gravel Pump

The NMG(GH) Series Gravel Pump is a cantilevered centrifugal pump featuring a single-casing structure connected by clamp bands. It offers excellent wear resistance, corrosion resistance, and high operational reliability. The pump is characterized by a rational structural design, reliable operation, and long service life. It is particularly suitable for the continuous handling of highly abrasive materials containing particles too large to be conveyed by conventional slurry pumps. The NMG(GH) Series is widely used in dredging operations on dredgers, river and channel dredging projects, slurry transportation for tunnel boring machines (TBMs), as well as the handling of slag and other abrasive materials in mining and metallurgical industries.

1. The pump adopts a single-casing structure secured by clamp bands, featuring a wide flow passage. Wetted components are manufactured from wear-resistant materials such as hard nickel and high-chromium alloys, providing excellent wear resistance, reliable performance, and good cavitation resistance.
2. The bearing assembly adopts a cartridge-type design and is equipped with high-capacity bearings. Both grease lubrication and oil lubrication are available to suit different operating conditions.
3. The clearance between the impeller and wear plate can be adjusted to ensure sustained high-efficiency operation.
4. Multiple shaft sealing options are available, including packing seal, expeller seal, and cartridge mechanical seal, to meet various application requirements.
5. The pump can be driven by direct coupling, V-belt drive, hydraulic coupling drive, or gear reducer drive, providing flexibility for different installation and operating conditions.
6. The discharge outlet can be positioned at any angle within 360°, allowing the pump to adapt to different site layout and installation requirements.
