MultiEco

Summary

Product identification

The KSB MultiEco is a self-priming, close-coupled, multistage centrifugal pump designed for domestic water supply systems and various water transfer applications.

Operating limits

• Flow rate (Q): ≤ 8 m³/h (≤ 2.2 l/s)
• Head (H): ≤ 54 m
• Fluid temperature (T):
  • ≤ +50 °C for continuous duty
  • ≤ +70 °C for 10 minutes
• Operating pressure (pd): ≤ 10 bar or ≤ 6 bar, depending on the specific size
• Suction lift (HS): ≤ 8 m

Feed water

The pump is suitable for handling:

• Clean to turbid water not containing aggressive, abrasive, or solid substances.
• River water, lake water, and groundwater.

Product water

Main applications include:

• Domestic water supply systems
• Spray irrigation systems
• General irrigation systems
• Rainwater harvesting
• Washing plants

Electrical

The MultiEco is available with single-phase AC or three-phase motors:

• Single-phase AC motor:
  • Rated voltage range: 220 - 240 V
  • Frequency: 50 Hz
  • Includes thermal overload protection
• Three-phase motor:
  • Rated voltage range: 380 - 415 V
  • Frequency: 50 Hz
  • Enclosure: IP44
  • Thermal class: F

Specific electrical data (P1, IN, power cable type and length) vary by model (e.g., MultiEco 33 P, 35 E, 65 D) and are tabulated in the official PDF.

Mechanical / hydraulic

• Design: Centrifugal pump, close-coupled, multistage, self-priming.
• Bearings: Deep groove ball bearings, grease-packed, sealed for life.
• Materials:
  • Pump casing: Grey cast iron with anti-corrosive coating
  • Discharge cover: Grey cast iron with anti-corrosive coating
  • Impeller/stage casing: Noryl
  • Shroud: Stainless steel
  • Shaft: Chrome steel
  • Motor housing: Aluminium
• Connections: Suction and discharge nozzle connections vary by model, typically G 1 or G 1 1/4 for suction and G 1 for discharge.
• Dimensions: Detailed dimensions (l1, l2, H, M) are provided in the official PDF, varying by pump size and model type (E, D, P).

Product benefits

• Reliable and sturdy installation due to corrosion-protected pump casing with a stainless steel jacket.
• Automatic and quick priming with a suction lift up to 8 m, enabled by its self-priming design (KSB patent).
• Energy-efficient and low-noise operation, achieved through a wear-resistant multistage hydraulic system with optimized efficiency.

Accessories

A range of accessories is available, including:

• Pump accessories: Connection parts (brass, Rp 1 / G 1, Rp 1 1/4 / G 1), suction strainers with foot valves (G 1), suction hose kits (G 1, 7 m), float switches (with NO or NC contact, H07RN-F3G1 power cable in 3 m or 5 m lengths), float switch weights (not for drinking water), and anti-vibration pump brackets.
• Control unit / switchgear accessories: Safety switch STECKMAT (1~230 V), and automatic control units such as Cervomatic EDP.2 and Controlmatic E.
