Hydrocyclone Feed Pump & Pressure PSI vs Operating Parameters


For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump … Read more

SRL Pump Performance -Lubrication & Gland Water Packing


As far as performance of SRL pump is concerned, it may be equipped with a VARIABLE SPEED DRIVE or the SIZE RATIO between the drive sheave on the motor and the one on the pump may be changed to increase or decrease RPM of the pump. To obtain maximum performance the distance between the impeller … Read more

SRL Pumps -Operating and Troubleshooting

SRL Pump

SRL Pump stands for Soft Rubber Lined, which means that it is designed to pump a slurry and is lined with soft rubber. There are other forms of lining that may be used for different types of acidic or highly abrasive slurries and of course companies experiment with different materials trying to increase the life … Read more

Diaphragm Pumps

Adjustable Stroke Diaphragm Pump Simplicity and ease of discharge regulation — while in operation—is one of the many distinctive features of the Adjustable Stroke Diaphragm Pump. This is accomplished by means of a conveniently located handwheel which operates a heavy rod, moving the pivot end of the connecting rod closer to the fulcrum point of the … Read more

Diaphragm Pump Working Principle

Diaphragm Pump

To begin, let’s start the description with the Diaphragm Pump and its Working Principle. The name of the diaphragm pump is derived from the RUBBER MEMBRANE that the pump uses to achieve its pumping action. The diaphragm works on an air displacement principle. The membrane is mechanically pushed and pulled in and out of a … Read more

Pumps in Mineral Processing


  The pumps in a mineral processing concentrator (plant) can roughly be classified into two groups, PROCESS pumps and SERVICE pumps. A service pump is any pump that provides a service to the process. A Process pump is one whose function is part of the process. The pump doing this type of job will be … Read more
