Stainless Steel Submersible Drainage Pumps

Detailed Information on Stainless Steel Submersible Drainage Pumps

Stainless steel submersible drainage pumps are professional pumps developed for drainage applications requiring high corrosion resistance. Thanks to their AISI 304 or AISI 316 stainless steel bodies, they provide chemical resistance, rustproofing, and long-lasting operation. They are preferred for the rapid discharge of clean water, rainwater, surface accumulation, and slightly dirty water.

Advantages

• • Full stainless steel body (AISI 304 / AISI 316)
• • High durability – long service life
• • Superior resistance to chemicals and corrosion
• • Quiet and efficient operation
• • Models with automatic float switches
• • Ability to drain at low water levels
• • High-clog-resistance hydraulic design for slightly dirty water

Operating Principle

The pump operates by being fully submerged in water. The stainless steel body rapidly dissipates heat underwater to cool the motor. The impeller structure adds energy to the fluid and delivers the water to the discharge line. The float system automatically starts or stops the pump when the water level reaches a certain point.

Material Structure

• • Body: AISI 304 / AISI 316 stainless steel
• • Impeller: Stainless steel or Noryl
• • Shaft: AISI 304 / 316
• • Motor: Submersible motor with thermal protection
• • Seal: Double mechanical seal (SiC/SiC – Carbon/Ceramic)
• • Strainer: Stainless steel design suitable for liquids with fine particles

Application Areas

• • Basement and parking lot water drainage
• • Rainwater drainage
• • Reservoir and tank emptying
• • Pool and decorative pond drainage
• • Landscape irrigation and water circulation systems
• • Slightly dirty water drainage
• • Saline or slightly chemical-containing waters

Performance Capacities

Stainless steel drainage pumps generally feature:
• 3 – 25 m³/h flow rate
• 5 – 20 m head (lift)
• 0.37 – 2.2 kW motor power
• Particle tolerance: 5 – 10 mm in standard models, 5 – 80 mm in vortex models. They offer longevity and high durability in industrial, commercial, and domestic drainage applications.
