In-line twin-head pump with two single-stage glanded centrifugal pumps in the same housing with switchover valve, for pipe installation or installation on a base. Housing blind flange and mounting brackets available at additional charge. Low-vibration and low-noise monobloc design with lantern and rigidly connected standard flange motor (standard motor). With forced-flow circulation, bidirectional bellows mechanical seal 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.
