If you are pumping sludge, high viscosity liquids, and media that contains solids, you should consider using progressive cavity pumps . Sometimes these pumps are called mono pumps, mono pumps or mohno pumps and they are the right pumps for demanding liquids and high gas. They can also be used to pump solid contents. With their benefits, these pumps can handle a lot of sensitive and challenging fluids – with low pulsation, gently and precisely.
Operating principles of mono pumps
Mono pumps are among the rotating PD pumps. They handle or pump liquids by conveying them into a conveying chamber and then displacing them. The conveying movement of these pumps is created by a rotating shaft. The shaft oscillates against a stator.
Because of the turning, the spiral geometry of the components, conveying chambers are created in which the medium flows from the inlet of the pump to the outlet. While the rotor of the pump is made of a hard material, the stator is elastic and made of an elastomer.
The viscosity and consistency of the fluid handled by the pump are irrelevant for the rate of flow with the mono pumps – the quantity pumped is determined by the speed. When combined with a frequency converter, the capacity of the pump can be controlled precisely and easily. The precision is five to three percent.
Funnel pumps with screw conveyors and bridge breakers are suitable for media that contains large amounts of dry material. For the best product supply, the medium is typically handled in a conical tamping area with transport screws.
Which liquids are mono pumps well suited?
Before you buy progressive cavity pumps, it is important to know if they are suitable for your application. Because they can handle liquids gently and powerfully at the same time, these pumps can be used for different types of liquids for which other types of pumps are not recommended. They are suitable for pumping liquids with these properties: adhesive, abrasive, aggressive, contains solids, low to high viscosity, shear sensitive, non-lubricating and lubricating, toxic and so on.
Media with such properties have to be handled in applications where there are very strict hygiene requirements. E.g., in the production of beverages, foodstuffs, and liquid food or in the cosmetic and pharmaceutical sectors. For such environments, there are mono pumps with high quality hygienic designs. The pumps comply with the relevant rules and regulations for hygienic pumps. The pumps can be cleaned reliability and they are dead space-free.
Regardless of the liquid to be pumped, mono pumps provide powerful suction up to 9 mWs, low noise running and quiet with low pulsation. Their direction of rotation and conveying can be reversed. This means that they can be installed in any position.
Benefits of mono pumps
Mono pumps have a conveying principle that provides several benefits. Low pulsation and continuous handling of high viscosity liquids. The pumps have an even rotation that avoids sudden changes in pressure. Progressive cavity pumps Australia have a high suction capability that works fun with high gas content. Another benefit is the gentle handling of media with high solid content.
