About us
Shijiazhuang Gravel Slurry Pump Industry Co.,Ltd is a huge manufacturer of slurry pump, Gravel sand pump, Dredging pump, Chemical pump, Multistage pump, Split case pump, Water pump, Submersible sewage pump and pump spares which are widely used in mining, metallurgy, coal washery, power plant, sewage water treatment, dredging, and chemical and petroleum industry.
Description
1.1MG Gravel sand suction dredge slurry pumps introduction:
1.Sand suction dredge pumps are designed for continuously handling the most difficult higher abrasive slurry which contain too big solids to be pumped by a common pump.
2.Dredging, suck gravel in the dredger, course of rivers.
3.Delivering slurries in mining, explosive sludge in metal smelting.
4.The discharge direction of pump can be oriented in any direction of 360°.
5.They are widely used for delivering slurry with strong abrasion and high concentration for metallurgy, mines, coal and power plant, etc
1.2The structure
Sand suction dredge pump's casing and spare parts are all made of high chrome, anti-wear, anti-abrasive material,so the dredge pump can have very longer life .
Sand suction dredge pump's discharge direction can be oriented in any direction of 360°.
Features
MG Series gravel sand suction dredge slurry pump:
1.Long wear life
2.High efficiency
3.Excellent suction performance
4.Ease of maintenance
5.Large sphere passage
6.Competitive price
7.Short lead time
8.100% interchangeable
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.
Seal Type
There are three standard shaft seal methods: Packing seal, Expeller seal, Mechanical 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.
Spare parts
Bearing assembly - a large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
Liners - easily replaceable liners are bolted, not glued, to the casing for positive attachment and east of maintance. Hard metal liners are completely interchangeable with pressure molded elastomer. Elastomer seal ring back all liner joints.
Casing - Casing halves of cast or ductile iron with exernal reinforcing ribs provide high operating pressure capabilities and extra measure of safety.
Impeller - front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and molded elastomrer impellers are completely interchangeable. Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
Throatbush - wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
Pump Base - a very robust onepiece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance
Application
Horizontal centrifugal mining slurry pump is widely used in transport slurry with slurry with strong corrosive proof and high concentration for many industries such as metallurgy, mine, coal, electric power, building materials and so on.
