Product questions
What power supply does the A 50-125CE need?
Calpeda lists a 0.75 kW, three-phase motor rated 230/400 V at 50 Hz. Check the motor nameplate and available supply before ordering; this is not the single-phase AM version.
What flow and head does this pump deliver?
For the listed 50 Hz version, Calpeda gives a flow range of 6–27 m³/h and a head range of 3.3–12.8 m. These are not simultaneous maximums; the operating point depends on the system.
Can the A 50-125CE handle slightly dirty water?
Calpeda specifies clean or slightly dirty water, with solids up to 10 mm for the A 50 size. Check the liquid, solids and operating conditions before selecting the pump.
Does this self-priming pump need liquid in the casing?
The built-in backflow preventer supports automatic re-priming. Calpeda states that re-priming can occur with the pump partially filled and the suction pipe empty; do not assume it can prime from a completely dry casing.
What connections and operating limits should I check?
The listed inlet and outlet are both G 2. Calpeda gives a liquid temperature range of −10 to +90 °C and a maximum casing pressure of 6 bar. For replacement, provide the existing pump nameplate and serial number to verify the configuration.
