What is a progressive cavity pump?
Progressive cavity pump is a type of pump useful for liquids and sludge with a series of viscotine. This design has a spiral shape mounted inside a sealed container. When the rotor turns, it pulls the liquid up into the container in a series of insulated cavities and drains the other end. The construction is also known as an eccentric screw pump, because it looks similar to a corkscrew inside the container, or as a Moineau pump, for a French inventor who first developed it. This pump does not need activation because it does not rely on maintaining pressure on operation and can handle very low streams and very strong materials, because the rotor acts mechanically to pull the liquid up until the drain pipes reach. The flow rate is adjustable by changing the rotation speed of the rotor, allowing the operator to decide how much fluid to move with the progressing cavity pump in a given time period. Maintenance requirements include shaft lubricationE rotor, periodically cleaning and output pipes to remove obstacles and confirm that the gasket is still tight.
Manufacturers with progressive cavity pump assemblies usually have a number of sizes and speeds for different applications. For customers, the uncertain model for its purposes can help it ask the company's representative for advice and assistance. It is important to select the pump capable of mastering the flow and consider future drawing needs; For example, if volumes are likely to increase, the purchase of a pump assessed for the current application is not enough because it will start with an overload when the volume rises.
Sometimes it is possible to rent a progressive cavity pump for a particular application or use in an experiment to see if it will meet the need. Companies can also offer leasing and sale of used pumps to provide more options. For companies who want to buy a new unit, the manufacturer canOffer regular offers for new customers that can reduce the price and increase the more affordable pump for gradual cavities.
