pump to dredge navigable canals

  Company Information Shijiazhuang Gravel Slurry Pump Industry Co.,ltd locates in Shijiazhuang, Hebei Province,China, it is an integrative production, research, design and sales company, specialized in manufacturing slurry pump products. The company acting as one of the national heavy machinery industry unit, now has been developed into a professional manufacturer of slurry pump, mud pump, slush pump, foam pump, sand-slurry pump.  pump to dredge navigable canals Advantage of our slurry pump: Competitive price; short lead time; powerful technical support for pump selection and problem solving Product Features MG detailed specification 1. Advanced hydraulic dredging pump model, CAD 3D design, high efficiency and obvious energy-saving 2. Large dredging sand depth, high density of dredging mud, good pump NPSH and strong suction lift ability. 3. Strong through-put. The dredging pump can persistently discharge gravel, high plastic soil lump,etc. 4.The dredging pump can be directly matched with either motor or diesel engine. 5. Wide application. The dredging pump can be used in various kinds of soil quality. Generally,the dredge pump is matched with an impeller with 3 or 5 pieces of vane. At the same time,the impellers can be provided with various diameters and vane types to suit kinds of working conditions. 6. Little hydraulic loss, high efficiency and low oil-consumption. 7. Little volume, light weight. 8. Steady operating, little vibration, low noise. 9. Simple & reliable constrution, easily disassembly & assembly,convenient maintainc 10. Reliable sealing without leakage. 11. Long operating life of parts  parameter selection   Shaft seal:   Packing Seal :
As one of the most commonly used seals for rotating shafts, the packing seal can come with low-flush or full flush arrangement which uses flushing water to prevent media from escaping the pump housing. This kind of seal is suitable for use under all pumping conditions. In situations where corrosive solids or high temperature might be encountered, Teflon or aramid fiber is used as the packing material for the gland. For high abrasion conditions, a ceramic shaft sleeve is available.  Expeller seal:  The combination of impeller and expeller creates the pressure needed to seal against leakage. Together with the gland seal or lip seal which is used as the shut-down seal, this type of seal can handle sealing requirements for applications where full-flush gland seal is impractical due to lack of water on the site, or sealing water is allowed to enter inside the pumping chamber to dilute the slurry.   Mechanical Seal :
MH series heavy duty slurry pump utilizes a leak-proof mechanical seal design which allows easy installation and replacement. Other types of mechanical seal are among options to suit the slurry pump for various pumping applications.   We also utilize special ceramic and alloys of high strength and hardness on parts that are subjected to friction. Unique design of and seamless fit between the mechanical seal and seal chamber provides excellent resistance to abrasion and shock that ensures its effectiveness under the toughest conditions.  Component diagram: Pump Prossible faults and removal:   Type MG pump has a compact construction. If it is correctly installed and operated, the pump will have a long life.

Faults	Reason	Removal
Pump fails to discharge any liquid.	Incorrect direction of pump rota- tion and impeller worn. Suction pipe blocked	Check direction of rotation and replace a new impeller
Power consumption on sh- aft is excessive	Rotating component is rubbing on a stationary part. Bearing worn. Drive belt tension too tight Flow rate too large Pump speed and ratio too high. Misalignment or unparallel of ddrive shaft and pump shaft.	Removal the rub Replace the bearing Adjust belt Modify the pump duty and speed. Adjust drive and pump shaft
Bearing is over hearing	Lubricants too much or less. Containing impurities in the lubricant Bearing worn.	Lubricating as requirements. Replace clean lubricant. Replace new bearing.
Bearing has short life.	Misalignment or unparallel of drive and pump motor. Shaft bent. Impeller unbalanced due to wear Foreign object entered into the bearing or insufficient lubrication Incorrect procedure followed in fitting bearings.	Adjusting drive and pump shaft. Replacing shaft. Remove rubbing and replace new impeller Clean the bearing. Replace or refit the bearings.
Pump vibrates or is noisy.	Bearings worn. Impeller unbalanced. Air entered into suction pipe or blocked. Flow rate is none—uniform and pump not primed.	Replaced by new bearings. Replaced by new impeller. Discharge air and remove block. Improve on the pump feeding.
