Vertical Pumps

The Kubota DF-V (Japan) vertical mixed-flow pump is the optimum choice for pump stations with limited footprint, high flow requirements, and varying head conditions. The motor is installed at a safe elevation above flood level; no priming devices are needed as the impeller remains submerged.

Key specifications:

• Suction bore: 200–4,200 mm
• Flow: 4–2,700 m³/min
• Total head: 5–150 m; 1–3 stages depending on bore
• Liquid temperature: 0–65°C; Ambient: -20–40°C
• Fluids: Fresh water, sewage, seawater
• Submerged bearings: Water-lubricated; thrust bearing oil-bath lubricated

Key features:

• Smaller footprint than horizontal pumps, reducing wet-well construction cost
• Motor elevated above flood risk — safe operation during inundation events
• No priming device required — simplified startup and operation
• Quiet, stable operation across wide flow range; suits variable demand
• Applications: Municipal water supply, irrigation pump stations, wastewater transfer
