Mixed Flow Pumps
Mixed flow pumps are dynamic pumps designed to deliver high flow rates at moderate heads—sitting between centrifugal (higher head) and axial flow (highest flow/lowest head) pump behaviour. They’re commonly used for large-volume transfer where you need more pressure than an axial pump can efficiently provide.
What are mixed flow pumps and how do they work?
A mixed flow pump uses an impeller that produces flow both radially and axially. As the impeller rotates, it adds velocity to the liquid and directs it through the casing/diffuser, converting that energy into useful pressure and flow.
They’re typically selected based on required flow, head, efficiency, and installation conditions (e.g., vertical, wet well, or inline arrangements depending on the range).
Typical applications
• Water transfer and distribution: high-volume pumping with moderate head
• Flood control / stormwater: moving large volumes with more lift than axial flow pumps
• Irrigation and drainage
• Cooling water circulation: industrial plants and power applications
• Water & wastewater: intake, transfer, and large-scale circulation duties
Why buy mixed flow pumps from Triark?
Triark can support pump selection, spares supply and aftercare—helping you choose the right mixed flow pump configuration for flow, head, intake conditions, materials compatibility, and operating duty, then supporting uptime with service parts and technical help.
Mixed flow pump spares and service
Common wear/service items include:
• Impeller and diffuser/wear surfaces
• Bearings and lubrication components
• Shaft seals (particularly in vertical or wet installations)
• Wear rings / clearances (model dependent)
Repair and maintenance
Good practice includes:
• Monitor vibration/noise and bearing temperatures (early wear indicators)
• Keep intakes/screens clear to reduce debris damage and performance loss
• Inspect seal condition and lubrication regularly
• Watch for performance changes (drop in flow/head can indicate wear, blockage, or clearance changes)
