Both vertical and horizontal multistage pumps do the same core job — build high pressure through several impeller stages — but their shape changes how they fit, sound and serve. Choosing between them is mostly about your plant room and duty.
Vertical inline multistage (AQB-HP-VM)
Our flagship, with the motor stacked directly above the pump.
- Compact footprint — takes up little floor area, ideal for tight plant rooms.
- High head — many stages in a small vertical envelope.
- Quiet operation — well suited to residential and commercial buildings.
Horizontal inline multistage (CHF / CHL / CHT)
The pump and motor sit side by side on a base frame.
- Low headroom — fits rooms where vertical clearance is limited.
- Easy access — components are reachable for service without lifting a tall assembly.
- Three metallurgies — CHF cast iron, CHL SS304 and CHT SS316 for different media.
Simple test: short on floor space but plenty of height → go vertical. Low ceiling or easy servicing matters most → go horizontal.
Metallurgy matters as much as orientation
Whichever orientation you pick, match the material to the water:
- CHF — Cast Iron: robust and cost-effective for clean water boosting.
- CHL — SS304: hygienic and corrosion-resistant; the popular all-rounder.
- CHT — SS316: for aggressive media, industrial and marine duty.
Control options apply to both
Either family can be supplied as a bare pumpset, with an auto controller (DB series), or as a smart VFD variant with IoT (DBS series) — so orientation and intelligence are independent choices.
Key takeaways
- Vertical (VM): compact footprint, high head, quiet — tight plant rooms
- Horizontal (HM): low headroom and easy servicing
- Match metallurgy: CHF (CI), CHL (SS304), CHT (SS316) to your media
- Both offer bare / DB auto-controller / DBS smart-VFD options
- Planned range 2–20 m³ across the pumpset family
