McKarlen Inline Pump Engineering Family
CI / VI Series – Horizontal and Vertical Inline Pumps
Horizontal and Vertical Inline Pumps
Inline pump solutions for HVAC, chiller, water circulation and technical piping in buildings and factories.
CI — Horizontal Inline Pump
VI — Vertical Inline Pump
Two configurations in one product family
CI and VI belong to the same McKarlen inline-pump family but use different physical configurations. Selection must consider system layout, installation conditions and operating data.
CI Series – Horizontal Inline Pump
- Horizontal inline configuration
- HVAC & Chiller
- Cooling water circulation
- Industrial piping
- Building services
- Factory utility systems
VI Series – Vertical Inline Pump
- Vertical inline configuration
- HVAC
- Water circulation
- Technical piping systems
- Building services
- Factory utility systems
Which configuration should you choose?
The two configurations suit different layout requirements. Product appearance alone is not a selection criterion.
CI Series – Horizontal Inline Pump
- Horizontal equipment arrangement
- Limited vertical clearance
- Horizontal access for maintenance
- Suited to corresponding piping and plant-room layouts
VI Series – Vertical Inline Pump
- Optimises floor space
- Vertical equipment and piping arrangement
- Limited floor space
- Suited to compact plant-room layouts
Final selection must consider flow, head, installation space, operating conditions and system drawings.
