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 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. Pump are equipped as standard with a PTC thermistor sensor for motor protection.
