A Self-filling centrifugal pumps with open impeller

The A-series includes Self-priming centrifugal pumps with open impeller in block construction, designed for applications with dirty water or solids.
An integrated backflow preventer in the suction nozzle prevents the siphon effect when switching off and ensures automatic refilling when restarting, even if the pump housing is partially filled.

Data sheet (incl. characteristic curves)

Execution

  • Pump type: Self-priming centrifugal pump with open impeller
  • Construction method:
    - Block design with directly flange-mounted electric motor
    - Open impeller for pumping media with solids content
    - Backflow preventer integrated in the suction nozzle to prevent the siphon effect
    - Self-filling even when the pump housing is only partially filled and the suction pipe is empty
  • Material variants:
    A: Pump housing and lantern made of gray cast iron
    B-A: Bronze pump housing and lantern

Applications

  • Pumping clean or slightly contaminated water
  • Media with solids content (up to 10 mm for A 40/A 50, up to 15 mm for A 65/A 80)
  • Basin and pit emptying
  • Irrigation systems in agriculture or horticulture
  • Use in civil facilities and industrial processes

Operating conditions

  • Medium temperature: from -10 °C to +90 °C
  • Ambient temperature: up to 40 °C
  • Maximum suction height: up to 8 m
  • Maximum permissible pressure in the pump body:
    - Standard: 6 bar
    - Model A 80-170: 10 bar
  • Operating mode: Continuous operation (S1)

Special versions (on request)

  • Deviating voltages
  • Operation at 60 Hz
  • Alternative mechanical seals
  • Extended temperature ranges (higher or lower medium or ambient temperatures)
