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.

Commissioning
Commissioning Glanded pumps
    
2219391

For perfect functioning of the pump(s) / system(s), it is recommended to have the commissioning carried out by the works' own WILO SE Customer Service Department. Optimum setting and efficient operation of the system are ensured as a result. Commissioning is comprised of the following points:

  • Commissioning of system(s) according to checklist
  • Parameterisation and setting of switchgear
  • Testing and adaptation of initial compressing of pressure tanks (filling up to 80 litres incl.)
  • Functional check of fitted system(s)
  • Practice-oriented operation instruction
  • Wilo commissioning protocol

The price for commissioning only applies to system(s) which have been installed in accordance with the installation and operating instructions and state-of-the-art technology. No costs for any materials which may be required are included.
