Summary

SAER ELETTROPOMPE KF Series (Peripheral Electric Pumps)

Product identification

The SAER KF series consists of peripheral electric pumps designed with a peripheral type impeller featuring numerous radial paddles. This design imparts kinetic energy to the pumped fluid, creating a rapid radial recirculation motion between the impeller blades and the pump body. This progressively increases pressure, resulting in a regular, non-pulsating flow and high pressures with steep curves.

Applications:

• Domestic systems
• Water supply
• Small gardening
• Emptying and filling cisterns
• Pressure boosting in aqueduct networks

These pumps operate only with clean fluids.

Operating limits

• Capacities: Up to 4.2 m³/h
• Heads: Up to 88 m
• Liquid temperature: From -15°C to +70°C
• Maximum operating pressure: 9 bar
• Maximum ambient temperature: 40°C (for higher temperatures, verification required)
• Manometric suction lift: Up to 8 m with a foot valve. For suction lifts above 5 m, installation of a suction pipe with an internal diameter larger than the pump inlet is advisable.
• Service: Continuous service for clear water (specific weight = 1000 kg/m³).

Feed water

• Liquid quality: Clean, free from solids or abrasive substances, and non-aggressive.
• Specific weight: 1000 kg/m³ (for clear water).

Electrical

• Motor type: Totally enclosed fan cooled (TEFC)
• Motor protection: IP 44
• Insulation class: B (for motors size 63), F (for other sizes)
• Standard voltage:
  • Single phase: 230V/50Hz
  • Three phase: 230-400V/50Hz
• Thermal overload protection: Built-in (single phase), user's responsibility (three phase).
• Capacitor: Permanently in circuit (single phase).
• Special executions are available upon request.

Mechanical / hydraulic

• Installation: Pump must be installed with the motor shaft in the horizontal position.
• Construction materials:
  • Pump body and motor support: Cast iron G20 (Bronze G-CuSn10 available on request)
  • Impeller: Brass
  • Shaft: Stainless steel, AISI 431
  • Mechanical seal: Carbon/Ceramic
  • O-Ring: Rubber NBR (Rubber EPDM available on request)

Dimensions and weights

• Inlet/Outlet connections: G 1” for all KF 0-3-4-5-6-1-2 models.
• Weights:
  • KF 0: 5.2 Kg
  • KF 3: 8.2 Kg
  • KF 4: 9.3 Kg
  • KF 5: 14.5 Kg
  • KF 6: 15.5 Kg
  • KF 1: 5.5 Kg
  • KF 2: 9.3 Kg
• Other dimensions: See the official PDF for exact tabulated values.

Hydraulic performance data

Performance curves are based on kinematic viscosity values = 1 mm²/s and density = 1000 kg/m³. The nominal power for specific models includes an overload coefficient: KF 3 (30%), KF 4 (40%), KF 5 (25%), KF 6 (10%), KF 2 (10%). See the official PDF for exact tabulated values of P1 Max (kW), P2 Nominal (kW, HP), absorbed current (A), flow rates (l/min, m³/h, U.S. g.p.m.), and head (m) for each model.

SAER ELETTROPOMPE CM-CMP Series (Electric Single Impeller Centrifugal Pumps)

Product identification

The SAER CM-CMP series comprises electric single impeller close-coupled centrifugal pumps, with the impeller directly splined onto the motor shaft. The hydrodynamic design of the impeller, with minimal hydraulic losses, transfers kinetic energy to the pumped liquid, which is then converted into dynamic pressure energy within the pump body's spiral volute.

Applications:

• Domestic systems
• Water supply
• Small gardening
• Pressure boosting in aqueduct networks
• Industrial water supply
• Horticultural and agricultural irrigation
• Civil and domestic water transfer

These pumps operate with clean and chemically non-aggressive fluids.

Operating limits

• Capacities: Up to 8 m³/h
• Heads: Up to 59 m
• Liquid temperature: From -15°C to +70°C
• Maximum operating pressure: 9 bar
• Maximum ambient temperature: 40°C (for higher temperatures, verification required)
• Manometric suction lift: Up to 8 m with a foot valve. For suction lifts above 5 m, installation of a suction pipe with an internal diameter larger than the pump inlet is advisable.
• Service: Continuous service for clear water (specific weight = 1000 kg/m³).

Feed water

• Liquid quality: Clean, free from solids or abrasive substances, and chemically non-aggressive.
• Specific weight: 1000 kg/m³ (for clear water).

Electrical

• Motor protection: IP 44 (IP 55 available upon request)
• Insulation class: B (for motors size 63), F (for other sizes)
• Standard voltage:
  • Single phase: 230V/50Hz
  • Three phase: 230-400V/50Hz
• Thermal overload protection: Built-in (single phase, on request), user's responsibility (three phase).
• Capacitor: Permanently in circuit (single phase).
• Special executions are available upon request.

Mechanical / hydraulic

• Installation: Pumps can be installed with the motor shaft in either horizontal or vertical position. If installed vertically, the motor must always be positioned above the pump body.
• Construction materials:
  • Pump body: Cast iron G20
  • Motor support: Aluminum alloy (Cast iron also mentioned in prose)
  • Impeller: Pressed brass or thermoplastic resin (Brass available on request for CM1 models)
  • Shaft: Stainless steel, AISI 304 (Stainless steel, AISI 431 available on request)
