The Caprari NC centrifugal pump is a single-stage horizontal pump conforming to EN733 (DIN24255), designed for building water supply and fire-fighting applications. The NCH variant handles high head (high-rise buildings), the NC.E/NCF variants carry EN12259-12 fire-fighting certification, and the MEC series couples a diesel engine for backup pumping per TCVN.
EN733 Standard — Why It Matters
NC complies with EN733 (DIN24255) — the European standard governing dimensions and connections of single-stage centrifugal pumps. Practical benefits: direct replacement of existing DIN24255 pumps without modifying pipework, and no vendor lock-in. The Back Pull Out design allows removal of the wet end (impeller, seal) without dismounting the motor or piping — enabling fast maintenance.
Series specifications: DN 32–250 mm · flow rate up to 450 l/s · head up to 160 m · power up to 355 kW · materials: cast iron / AISI 316 / Duplex.
Complete Caprari Fire-Fighting System
A building fire-fighting pump station per Vietnamese code requires 3 pumps:
- Main electric pump: NCH (high head for high-rise buildings), NC.E/NCF variants certified to EN12259-12.
- Diesel backup pump: MEC directly coupled to a diesel engine (SAE3/4/5) — mandatory per TCVN.
- Jockey pump (pressure make-up): CVX multi-stage vertical.
Reference projects: Pullman Hotel Hải Phòng (NCH100-315), Cityland Tower, Bcons Miền Đông (NCH + CVX + MEC).
Technical Notes
- Maximum suction head for NC is ~7–8 m — verify NPSHa before finalizing order.
- Fire-fighting in high-rise buildings (H > 80 m) → use NCH.
- Fire-fighting applications require confirmation of EN12259-12 certification (NC.E / NCF).
