Series G sand gravel pumps are designed to handle very large particles for gravel and dredging operations. G series sand pumps are qualified for the continuous handling of the most difficult higher abrasive slurry, containing solids too large to be pumped by a standard slurry pump.

Tech-macro Dredge and Gravel pumps is designed to provide continuous pumping of highly abrasive slurries containing large particles at high maintained efficiency with low maintenance and ownership costs.
Description (Technological Characteristic:)

Construction of this pump is of single casing connected by means of clamp bands and wide wet-passage.The wet-parts are made of Ni-hard and high chromium abrasion-resistance alloys.This type of pump possesses the advantages of easy installation and operation.

1. Horizontal, cantilevered, single-casing structure, centrifugal pump.
2. Wide passage , good performance of NPSH, anti-wearing and anti-corrosion, high efficiency
3. Easy installation.discharge outlet can be adjusted at any direction of 360.
4. Cylinder bearing assembly,grease lubrication ,adjusting the distance between impeller and pump.
5. Mechanical seal, expeller seal and packing seal for selection.
6. Drive type: V-belt drive, gearbox drive, elastic coupling drive, fluid couplings drive, frequency conversion drive, silicon controlled rectifier speed regulation,etc.

Applications

Series G sand pump is widely used in the sand excavation, dredging, mining, coal washery,

power plant, metallurgy, petrochemical and other industrial departments, etc. 

G sand pump has far better performance than common pumps in dredging, sand

mining, barge loading and mineral processing, etc. Featured with all the advantages of G series,

G(GH) series sand pump has achieved extra high head for special working conditions.
