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. 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.   related product: We can produce many kinds of centrifugal slurry pump for mining, sand and other solids slurry transporting.

All Pump Spare Parts shijiazhuang gravel slurry pump company workshop dredging pump processing:   Pump Prossible faults and removal:

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.
