Caisson Well Submersible Pumps

Detailed Information on Caisson Well Submersible Pumps

Caisson well submersible pumps are specialized submersible pump models designed for water supply from shallow but wide-diameter wells. They are ideal for caisson wells where water levels may fluctuate seasonally and are designed to provide uninterrupted suction even at low water levels. They are widely used for the reliable and silent transfer of clean water.

What is a Caisson Well?

Caisson wells are typically 1–2 meters in diameter, with reinforced concrete or brick walls, collecting water close to the surface. Although they require lower head (lift) compared to deep well pumps, they need to be fed by powerful and efficient submersible pumps since water is drawn from a large volume.

Pump Features

• • Medium pressure – high flow rate production
• • Multi-vane impeller design suitable for shallow wells
• • Stainless steel body and motor protection
• • Silent motor structure
• • Models with automatic float switch control
• • Options with water circulation jackets for rapid cooling

Material Structure

• • Body: AISI 304/316 stainless steel or cast iron
• • Impeller: Noryl, PPO, or stainless steel
• • Shaft: Stainless steel AISI 304/316
• • Seal: Double mechanical seal – SiC/SiC, Carbon/Ceramic
• • Motor: Fully hermetic submersible motor

Application Areas

• • Water supply from caisson wells
• • Garden and hobby garden irrigation
• • Small agricultural irrigation systems
• • Reservoir and tank feeding applications
• • Residential water pressurization systems
• • Clean water transfer at low depths

Performance Capacities

Caisson well submersible pumps are generally manufactured with:
• 3 – 30 m³/h flow rate
• 10 – 70 m head (lift)
• 0.75 – 7.5 kW motor power range. They offer high-efficiency, long-lasting, and silent solutions for shallow and large-volume wells.
