Tender text

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 and 45 kW/2-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. Flange with R 1/8 pressure measuring connections. 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.
