Calpeda Peripheral close coupled electropumps - Ct

Applications

For clean liquids without abrasives, without suspended solids, non-explosive and non-aggressive for the pump materials.

For increasing network pressure (follow local regulations).

Due to their compact dimensions, these pumps are highly suitable for installation in cooling and air-conditioning systems and equipment, as well as for circulation applications.

Operating conditions

Liquid temperature up to 60 °C.

Ambient temperature up to 40 °C.

Total suction lift up to 7 m.

Continuous duty. (S3 60% for three-phase).

Motor

2-pole induction motor, 50 Hz (n ≈ 2900 rpm).

CT: three-phase 230/400 V ± 10%.

CTM: single-phase 230 V ± 10%, with thermal protector.

Capacitor inside the terminal box.

Insulation class F.

Protection IP54.

IE2 efficiency class for single-phase motors.

IE2 efficiency class for three-phase motors.

Constructed in accordance with EN 60034-1; EN 60335-1, EN 60335-2-41.

Special features on request

Other voltages.

Frequency 60 Hz (as per 60 Hz data sheet).

Special mechanical seal.
