Pump Technology Home
Pumps are the most common machine known to man. There are many type of pumps, but mostly divided into two categories. Centrifugal pumps, and Positive displacement pumps. Centrifugal Pumps are machine that used the centrifugal force exerted on the liquid to drive the medium being pump. Positive Displacement Pumps are pumps that will rotate or displace an element, and it will push the water out.
We are going to take a look at this time into the positive displacement pump, and specifically the progressive cavity pump or PC Pump.
Progressive Cavity Pump
PC Pumps or helicoidal pumps have two main elements. One rotating inside the other one. The stationary element is called a stator and is mostly manufactured of rubber; although, some Progressing pump manufacturers make them out of teflon, or steel. The rotating element is called a rotor, and it resembles an elongated pig tail. Rotor manufacture can be of many different materials and coatings. Most commonly, Rotors are made of steel or stainless steel, and are coated with chrome.
Progressive cavity pumps are commonly used in applications where solids, or low emulsions are needed. Some progressing cavity pumps can pump up to 2 inch solids without a problem. They are also very easy to meter as the flow per revolution are known.
There are many different sources of pumps and pump resources on the net. For more information about pumps you can follow this progressive cavity pump information.
