AF Seried Paper and Flotation Application Vertical Froth Pump

  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.   Advantage of our slurry pump:   Competitive price; short lead time; powerful technical support for pump selection and problem MF product feature 1. What is a froth pump?  The MF froth pumps has been designed to increase the pumpability of frothy slurry. The pump operation is similar to hydrocyclone seperation.  The basic principle of the froth pump operation is to de-aerate or partially de-aerate the froth before it enters the pumping. Its handling capacity of the pump is muchhigher than that of other types of slurry pump without shaft seal and sealing water.  2. What advantage of MF slurry pump? The advantages of the pump are of excellent performance, easy assebly & disassembly, high and etc.
The MF series froth pumps is a efficiency pump are suitable for handing solids-liquid mixture, special for delivering frothy pulp generated in flotation machines in metalliferous and coal flotation circuits. The MF froth pump is ideal for all applications involving handling of air entrained slurries, such as flotation froth in base metal concentrators, phosphate and apatite washing plants and calcium carbonate upgrading plants. The pump can also be used as a mixing and distribution unit, where dry powder has to be mixed (and wetted) with water. It can also be used with cement in ready mixed concrete and for grouting and injection mixing.  3. What structure of the MF froth pump The construction of pump head is double casings slurry pump. All wet-parts can be supplied in Ni-hard, high chrome alloy iron and pressure-moulded natural or synthetic rubber. The driver end can be exchanged with that of type--SP(R) pumps. The hopper-tank is fabricated with steel plate. Its inner wall of the tank can be covered with liner according to different medium pumped. The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.  parameter selection   Meanings of the model: MF2Q

All of the metal wet parts can are made of high chromium alloy which has superior wear and erosion resistance or grey iron which has a high rigidity. 2. As the expeller ring is assembled together with the expeller, much pressure can be reduced effectively for the impeller. Meanwhile, it can still maintain a reliable sealing performance. 3. The parts such as labyrinth, labyrinth locknut, end cover and shaft sleeve are used for bearing assembly; these parts can be changed easily and have high accuracy and longer service life. 4. Some fastening parts such as studs and bolts can be used for fixing the other parts securely. All the fastening parts can be attached easily, ensuring the safety. 5. All of the rubber parts have superior erosion resisting performance which can be used for a long life. Pump Prossible faults and removal:   Type MF 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.
