Atmos GIGA-B 40/125-0,75/4
Single-stage glanded centrifugal pump in monobloc design for installation on a base.
Low-vibration and low-noise monobloc design with lantern and rigidly connected standard motor.
With force-flushed, bidirectional bellows mechanical seal (from 37 kW/4-pole, optionally available with a cartridge mechanical seal in back pull-out design for mechanical seal replacement without dismantling the motor) and cavitation-reducing impeller.
Flanges with pressure measuring connections R 1/8. The pump housing and lantern are cataphoretic-coated.
Motors in IE3 technology as standard. Pump with motor ≥ 5.5 kW are equipped as standard with a PTC thermistor sensor for motor protection.
The motor terminal box ≤ 7.5 kW can be made of metal or plastic. If a metal terminal box is absolutely necessary, please order the appropriate special variant. The motor terminal boxes > 7.5 kW are always made of metal.
