What is a progressive cavity pump?

Sometimes referred to as an eccentric screw pump or simply a cavity pump, a progressive cavity pump is a device that allows you to move through a number of small chambers or cavities using a rotor. This type of effect allows you to control the flow of liquid in a way that ensures that the progress of flow is consistent and easily managed. Pumps of this type are used in a number of different applications, including drilling for oil, water and natural gas.

While there are slightly different design elements in different versions of the progressive cavity pump, most of the models have a spiral rotor together with a number of smaller chambers or cavities. The stator, usually made of rubber, works in a tandem with a rotor and creates a safe seal. As the rotor initiates movement, each of the chambers or cavities also moves, the filler continues during the rotation.

The advantage of this design is that it is possible to use progressive cavity pumps to move the liquid at a slower pace while applying the liquida variety of pressure speeds. The wear of the pump itself is kept to a minimum, as each subsequent cavity must only deal with the level of pressure related to the transfer of the liquid to the next chamber. This helps maintain a constant pressure balance while providing a certain degree of control that is not possible in other types of pumps.

There are a number of different applications for progressive cavity pump. In the case of oil wells, this type of device is ideal for pumping oil through the well and into storage containers. Many sewage systems use this type of pump as a means of controlling the flow of waste water and sludge by the cleaning process. It is not unusual for corporations that use a large amount of chemicals in their production processes for the use of a progressive cavity pump to ensure that the exact amount of each chemical compound is used in any product.

There are other uses for a progressive cavity pump. Winery canUse the pump to move the liquid after the distillation process at a measured pace. The shipyards and other marine centers often use the progressive cavity pumps as part of the process of lubricating engines and filler tanks. The pump of this type can even be used in building projects to move cement and grouting to the position.

, which has been developed for the first time in 30 years, there are a number of different names for a progressive cavity pump. Some of these names are related to the intended purpose of the pump, while others are associated with the pump brand produced by a particular company. While the name differs, the basic function of the progressive moving liquid via the controlled channel of the chamber remains the same.
