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:
drive type:
DC Type: The output shaft of a motor is directly connected to the input shaft of a pump via a pump coupler. This type of connection is suitable for applications where the speed of the slurry pump is the same as that of the motor.
CV Type: The pump is driven by a belt connected to the crankshaft of the engine. This way of connection allows for saving space, easy installation, and fast adjustment of pumping speed. The motor is fixed to the motor support frame which is located on the bearing support above the slurry pump.
ZV Type: Another type of belt drive that allows easy adjustment of pumping speed. The motor is directly fixed to the bearing support. This way of installation is suitable for motors with larger horsepower than is possible with CV type of installation. Due to the installation of motor onto the bearing support, this method helps save installation space.
CR Type: This type of belt drive makes it easier to adjust pumping speed. The installation allows both the motor and slurry pump to be fixed to the ground. The motor is installed to the side of the pump. This installation method is suitable for large-power motors.
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.
