Product introduction

Product introduction:

SG Series Gravel Pump: The impeller, guard plate, and wet flow parts are made of metal material.

SGH Series High Head Gravel Pump: The impeller, guard plate, and wet flow parts are made of metal material.

The pump shaft seal: Stuffing seal, auxiliary impeller + stuffing seal, mechanical seal.

The pump is suitable for Conditions where the particles are too large and the materials are highly abrasive, which cannot be continuously transported by ordinary slurry pumps. It is suitable for mud dredging by dredgers, river dredging, mining, and transportation of blast slag in metal smelting, etc.

Structural Features:

1. Horizontal, single-stage single-suction, cantilever, single pump case structure gravel pump.

2. This pump adopts a single pump case structure with a cassette connection, and the flow channel is wider than other slurry pumps.

3. Excellent cavitation performance.

4. The discharge direction of the pump can be in any position of 360°, which has the characteristic of convenient installation and use.

5. The bracket part adopts adjustable vinegar lubrication, with an external oil injection nozzle for convenient maintenance.

6. Small size, lightweight, simple structure, easy to disassemble, easy for workers to maintain, saving a lot of labor.

7. The product is designed using CAD design method, excellent hydraulic performance, high efficiency, energy-saving, long service life, reasonable structure, reliable operation, low vibration and low noise, and convenient maintenance.

8. The flow parts are made of various metal materials, good wear and corrosion resistance, low product wear rate, and the overall efficiency declines slowly and smoothly as the flow parts wear out.



Production capacity

The total design and production capacity of our factory is 10,000 units (sets) per year, and we can produce 2,000 tons of various high-chromium alloy castings annually. The production area currently includes the following production zones. Namely:casting workshop, heat treatment workshop, machining workshop, metal forming and welding workshop,assembly and painting workshop, spare parts warehouse and finished parts warehouse; Two centers:quality inspection and analysis center and the overall hydraulic test center. 

Our products are mainly made of high-chromium wear-resistant white cast iron such as A05, A07, A49, A33, etc. The product development and process formulation all adopt CFD and CAPP new technologies. All castings use resin sand molding and newly introduced lost foam casting technology, which can pour 8-10 tons of castings at one time. The heat treatment workshop has two 20 cubic electric resistance heat treatment furnaces, and the machining shop has two large vertical lathes of 4.2M and 4.5M and more than 20 other types of machine tools. In addition,there are various types of hoisting equipment,metal cutting and welding equipment,impeller level tuning equipment,molding equipment,sandblasting polishing equipment.

Our main products includes a full range of slurry pumps, desulfurization pumps, gravel pumps, dredging pumps, foam pumps, chemical process pumps, PU rubber slurry pumps, and other dozens of varieties, hundreds of models.Widely used in mining (mineral processing), metallurgy, coal, power plant, flue gas desulfurization, silt dredging, sewage treatment industries, chemicals, municipal and environmental protection and so on.
