Mixed flow pumps

Mixed flow pumps are hydraulic devices designed to pump fluid where the flow moves along the axis of the pump (axial flow) and around the axis of the pump (radial flow). These pumps are widely used in various fields such as water supply, irrigation, and industry for pumping water, wastewater, liquid fertiliser and other liquid media. They are characterised by high efficiency and the ability to deliver a large volume of pumped liquid at a relatively low lift height.

Sandpiper plastic series

Sandpiper plastic series

The SANDPIPER Non-Metallic AODD Pumps for standard applications are one of the most popular diaphragm pump series. The pumps are available in a wide range of sizes (1/4'' - 3''), casing materials and elastomers. The pumps are most commonly used in production areas where aggressive and explosive liquids need to be pumped. Due to their light weight, these pumps are used in portable versions for pumping liquids from drums.

Flow Range:up to 1060 l/min
Temperature:depends on elastomer
Pressure:up to 7 bar
Solids:up to 19 mm
Materials:corrosion-resistant polypropylene or PVDF
Dimensions:up to 3''
Hygienic Series

Hygienic Series

Pneumatic diaphragm pumps of the hygienic series are made of polished stainless steel AISI 316L. The pumps are hermetically sealed, self-priming, and are designed primarily for pumping of slightly aggressive media, food and cosmetic products. They are used in those industries where there are increased requirements to hygiene, for example dairy production.

Flow Range:max. 850 l/min
Temperature:up to 120°C
Pressure:8 bar
Solids:max. 15 mm

Dellmeco plastic series

Dellmeco plastic series

DELLMECO air-operated diaphragm pumps (AODD) are suitable for a wide range of applications. They have high abrasion resistance and can withstand aggressive chemicals, including acids, oils, solvents, paints, sludge and even media containing solid particles, such as in wastewater. These pumps can also be used for pumping powders.
All pumps are self-priming and their performance and pressure can be easily controlled. This pump is a positive displacement pump that pumps liquids by the movement of diaphragms driven by compressed air. The casing in contact with the liquid is made of polyethylene (PE), polyethylene conductive, polytetrafluoroethylene (PTFE), polytetrafluoroethylene conductive.

Flow Range:up to 850 l/min
Viscosity:max. 20.000 mPas
Temperature:max. 110 °С
Pressure:up to 8 bar
Solids:max. 15 mm
Materials:polyethylene, fluoroplastic, teflon, including conductive
Dimensions:up to 3 in.

Mixed-flow pumps

Mixed-flow pumps

Industrial mixed-flow pumps are important equipment for pumping liquids in various industries. These pumps provide efficient operation due to their ability to create a liquid flow that combines axial and radial directions of movement.

Mixed-flow principle

A mixed-flow pump is characterized by the fact that the liquid simultaneously moves along the pump axis and around it. This allows the pump to efficiently pump both large volumes of liquid and provide a significant lifting height.

Applications in various industries

Industrial mixed-flow pumps are used in various fields of activity. They are widely used in water supply and drainage systems, in agricultural irrigation, as well as in industry for pumping water, wastewater, aggressive liquids and other media.

Industrial mixed-flow pumps

Advantages of mixed-flow pumps

The use of mixed-flow pumps has a number of advantages. One of the main ones is high efficiency at large volumes of pumped liquid and relatively low head. In addition, these pumps have good adaptability to various operating conditions and reliability in operation.

Choosing a mixed flow pump

When choosing a mixed flow pump, it is necessary to take into account a number of factors, including the required volume and head of the liquid, the characteristics of the medium, operating conditions and other parameters. Professional consultants can help you choose the most suitable option, taking into account all the requirements and features of your project.
