Our mix flow pump range, also known as diagonal flow pumps or mixed flow centrifugal pumps, occupies the performance space between purely axial flow and radial centrifugal pump designs. This intermediate characteristic makes them the optimum choice for applications requiring flow rates and head values that neither axial flow nor conventional centrifugal pumps can serve efficiently on their own. Manufactured at our Ahmedabad, Gujarat facility, our mixed flow pumps are globally recognised for their flawless performance, wide adaptability and strong after sales service network.
Our AF model mix flow pump range is available in vertical and horizontal configurations, sealed and seal-less variants, and in sizes from 6 inch to 30-inch nominal diameter to match the flow requirements of municipal, agricultural, industrial and power sector installations.
Propeller Pumps is one of the leading manufacturers, exporters and suppliers of Mix Flow Pumps and Mixed Flow Water Pumps in India, exporting to worldwide destinations including UAE, Saudi Arabia, Singapore, Indonesia, Philippines, Egypt, Ethiopia, Nigeria, Kenya, Russia, Uzbekistan, Kazakhstan and across the globe.
Mixed Flow Pump Model Features and Configuration Options
The AF model mixed flow pump range from Propeller Pumps is available in a wide variety of configurations to address the diverse requirements of industrial, municipal and agricultural pumping installations.
Pumps are available in cast iron, stainless steel and nickel chrome alloy base materials as standard. Where service conditions demand specific alloy properties, customers are invited to specify their preference and our engineering team will confirm the most appropriate material solution for the duty. This flexibility in material selection allows our mix flow pumps to be used in applications ranging from clean water service through to mildly corrosive or mildly abrasive liquids.
The shaft sealing arrangement incorporates a cylindrical bored stuffing box that ensures long seal life by maintaining consistent face contact geometry throughout the operating cycle. For applications where any fluid emission is unacceptable, seal-less configurations of the AF model are also available. The robust bearing frame and shaft assembly maintain their structural integrity and alignment even when the propeller is operating in demanding or critical service conditions, ensuring long term durability without premature wear.
A specially designed pedestal bearing arrangement provides additional shaft balancing support in adverse operating conditions, maintaining shaft alignment and reducing vibration under off design flow conditions. Vertical or horizontal configurations of the propeller assembly are available, and the pump can be specified as sealed or seal-less depending on the client requirement.
The AF model mix flow pump is available with low NPSH requirements, which is an important advantage in installations where the available suction head is limited, such as low water level pump stations, irrigation headworks and tidal intake structures.
Mix Flow Pump Efficiency, Versatility and Low Vibration Benefits
The performance characteristics of our AF model mix flow pumps are built on three core operational strengths that our customers value highly.
Efficiency is achieved through innovative propeller design geometry that allows each mix flow pump to realise its maximum hydraulic potential at the specified flow and head duty point. This efficiency translates directly to reduced energy consumption and lower operating cost, which is particularly significant in large scale water supply, irrigation and industrial cooling applications where the pumps run continuously or for extended periods.
Versatility is delivered through the wide range of AF model sizes, configurations and material options available. Whatever the pumping requirement, whether vertical or horizontal installation, sealed or seal-less operation, corrosion resistant or standard alloy construction, inline or open channel siting, the AF model mixed flow pump range can be configured to meet the specification precisely.
Minimal noise and vibration characterise the operation of our mix flow pumps across the entire flow range. The propeller design and balanced rotating assembly minimise mechanical vibration and acoustic emission, making these pumps suitable for installation in residential proximity infrastructure, water supply stations and environmentally sensitive locations.
Mixed Flow Pump Maintenance and Service Network
Both the service life and the sustained performance of our mixed flow pumps are maximised by following the manufacturer recommended maintenance schedule of a routine service inspection every two to three years. This extended maintenance interval is achievable because of the robust mechanical design and quality of materials used in each pump, and it represents a significant advantage over pump types that require more frequent intervention.
Propeller Pumps supports its customers with a comprehensive service network that is capable of providing timely maintenance and repair services regardless of the geographic location of the installation. This strong service network is an integral part of the value proposition of the AF model range, ensuring that the long-term performance and reliability of every mixed flow pump installation is maintained throughout its service life.
The AF model mix flow pump is the ideal and dependable solution for any high flow or high capacity pumping requirement, capable of handling corrosive fluids, abrasive slurries, extreme temperature liquids and hazardous process fluids without compromising its performance or operational reliability.
