LD Series — Rigid Long-Coupled Pumps
Featuring a spacer coupling and dedicated bearing bracket to thermally isolate the motor. Back Pull-Out design lets service teams replace seals without removing the motor. Ideal for district heating & cooling towers. |
SL Series — Compact Close-Coupled Pumps
Stub-shaft architecture with impeller keyed directly to the motor. Saves up to 40% footprint, eliminates shaft coupling alignment issues, and reduces vibration. Perfect for HVAC skids and OEM packages. |
HVAC Utility & Process Cooling Network Specifications
The operational grid below represents FILIPUSI's validated engineering limits. Casing patterns can be modified at our foundry for high-pressure or aggressive fluid demands:
| Engineering Metric | Design Threshold & Regulatory Standard Match |
|---|---|
| Volumetric Flow (Q) | Up to 1,200 m³/h (Custom trimmed impellers to hit exact condenser & cooling tower BEP points) |
| Discharge Head (H) | 12 to 160 Meters (Optimized for high-rise commercial vertical head losses and district loops) |
| Thermal Operating Band | -10°C to +120°C (Handles sub-zero ethylene glycol mixtures up to super-heated water loops) |
| Casing Pressure Class | Standard PN16 pressure limits / Reinforced PN25 optional for high-static skyscraper boosting |
| Advanced Metallurgy | Grade 250 Cast Iron (HVAC), Ductile Iron (High-Head), SS316L / Zinc-Free Bronze (Corrosive Seawater) |
| VFD Automation Integration | Fully compatible with external VFD controllers via Modbus / BACnet standard PLC communication protocols |
Micrometric Alignment: Eliminating Radial Run-Out
FILIPUSI CNC machining centers process motor registers, bearing brackets, and seal chambers within a single structural setup. This micrometric concentricity ensures the shaft rotates strictly on its central axis, eliminating localized run-out, preventing mechanical seal leakage, and extending routine maintenance cycles by up to 40%.
Field Selection Guide — Resolving Pipeline Centrifugal Engineering Challenges
Q1: What are the primary installation advantages of a vertical inline layout over traditional horizontal end suction configurations?
A: Inline pumps install like standard valves directly in horizontal pipelines, cutting baseline footprint requirements by up to 50%. This eliminates complex concrete inertia foundations and shields assemblies from thermal pipe expansion alignment issues.
Q2: How does your vertical long-coupled series streamline emergency mechanical seal replacement?
A: The LD series features a heavy-duty spacer coupling. Technicians can extract the mechanical seal cartridge through the side gap after unbolting the spacer, replacing seals in under one hour without disturbing the electric motor or breaking pipeline flanges.
