Calpeda Peripheral close coupled electropumps - T, Tp

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 from -10 °C to +90 °C.

Ambient temperature up to 40 °C.

Total suction lift up to 7 m.

Maximum permissible pressure in the pump casing: 12.5 bar, (16 bar for TP series).

Continuous duty.

Motor

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

T, TP: three-phase 230/400 V ± 10%.

                            400/690 V ± 10%, from 4 to 7.5 kW;

TM, TPM: 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.

IE3 efficiency class for three-phase motors (IE2 up to 0.65 kW).

Constructed in accordance with EN 60034-1; EN 60034-30-1.

EN 60335-1, EN 60335-2-41.
