split case fire pump — End suction and split case centrifugal fire pumps serve different flow ranges and pump room layouts; export buyers should match type to hydraulic calculations and maintenance access. This guide focuses on practical evaluation steps for U.S. industrial and commercial buyers—hydraulic duty, documentation, and lifecycle support—not generic marketing claims. Where equipment selection is involved, cross-check public specifications on borrapumps.com and confirm project-specific limits with your consulting engineer or AHJ. Section checklists can be reused as RFQ attachments and commissioning handover outlines.
Part 1. Hydraulic and Layout Differences
This section supports export and U.S. project buyers evaluating split case fire pump with practical checks tied to site data and supplier documentation.
Confirm flow, head, power, installation constraints, and local code expectations before issuing purchase orders.
Cross-check public product specifications on borrapumps.com and request missing test or curve data in writing.
Fire pump selection starts with the approved hydraulic calculation and the governing code edition referenced in project specifications.
End-suction and split-case designs trade footprint, efficiency, and maintenance access—confirm AHJ and insurer expectations before finalizing.
Cross-check fire pump packages ratings against the duty point on the pump curve, not catalog headline flow alone.
Capture rated flow, total dynamic head, fluid properties, and suction conditions in the RFQ package to reduce back-and-forth during technical review.
If the site mixes intermittent peaks and sustained duty, size the driver for the governing thermal condition—not catalog nameplate alone.
Define acceptance criteria before shipment—flow, head, efficiency, or NFPA witness points—so commissioning disputes are less likely.
Part 2. Maintenance and Spare Parts Planning
This section supports export and U.S. project buyers evaluating split case fire pump with practical checks tied to site data and supplier documentation.
Confirm flow, head, power, installation constraints, and local code expectations before issuing purchase orders.
Cross-check public product specifications on borrapumps.com and request missing test or curve data in writing.
Driver selection (electric vs diesel) must match site utility rules, backup power strategy, and witnessed test requirements.
Jockey or booster stages maintain system pressure between main pump runs—size them to avoid excessive cycling.
Review application and solution pages for packaged skid options when field assembly time is constrained.
Capture rated flow, total dynamic head, fluid properties, and suction conditions in the RFQ package to reduce back-and-forth during technical review.
If the site mixes intermittent peaks and sustained duty, size the driver for the governing thermal condition—not catalog nameplate alone.
Define acceptance criteria before shipment—flow, head, efficiency, or NFPA witness points—so commissioning disputes are less likely.

|---|---|---|
| Duty-point data | Matches pump curve selection | Consulting engineer |
| Installation clearance | Service access and safety | Mechanical contractor |
| Control interface | Reliable start/stop and alarms | Electrical contractor |
Part 3. RFQ and Documentation Checklist
This section supports export and U.S. project buyers evaluating split case fire pump with practical checks tied to site data and supplier documentation.
Confirm flow, head, power, installation constraints, and local code expectations before issuing purchase orders.
Cross-check public product specifications on borrapumps.com and request missing test or curve data in writing.
Acceptance testing should document flow, pressure, and driver performance at agreed load points.
Keep as-built drawings, valve settings, and controller programming with the O&M manual.
Submit NFPA or owner witness parameters via BORRA engineering contact when duty falls outside standard tables.

Part 4. Documentation and Handover Checklist
Industrial acceptance should not rely on energization alone—documentation proves ratings, safety, and maintainability for the next maintenance cycle.
Use the tables below as a starting RFQ checklist; your AHJ, insurer, or EPC contract may require additional items.
For product-specific datasheets, cross-check fire pump packages and request any missing factory test excerpts.
Align factory acceptance tests with items your insurer or owner witness agreement may require.
When comparing quotations, normalize currency, Incoterms, and included commissioning services before ranking suppliers.
| Document / item | Purpose | When to request |
|---|---|---|
| Factory pump performance curve | Verify flow, head, efficiency, and NPSHr at rated speed | Before purchase order |
| Driver nameplate and coupling data | Electrical service and alignment | Design phase |
| Installation and O&M manual | Commissioning and maintenance planning | Before FAT/SAT |
| Spare parts list (5+ year) | Seal kits, impellers, bearings lifecycle | Contract negotiation |
| Commissioning / acceptance checklist | NFPA or owner witness tests | Before energization |
| Application | Duty profile | Typical pump approach |
|---|---|---|
| Municipal fire protection | Sustained rated flow + overload | End-suction or split-case with listed driver |
| Industrial hazard | Variable demand + jockey | Main fire pump + jockey/booster package |
| High-rise booster | Steady pressure maintenance | Vertical multistage or inline booster |
| Skid package export | Fixed layout, witnessed test | Factory-assembled skid with documented FAT |
Part 5. Commissioning, Monitoring, and Long-Term Operations
Commissioning should verify flow, head, and driver performance at the agreed duty points—not only at no-load or nameplate conditions.
Functional tests typically include vibration, seal leakage, control response, and documented comparison to the factory pump curve.
Monitoring after startup helps catch cavitation, hunting, or seal wear before they affect production or fire protection readiness.
Train maintenance staff on lockout/tagout, priming procedures, and which alarms require immediate shutdown versus scheduled service.
Schedule a post-warranty review to reassess duty changes—plant expansions often change flow profiles within three to five years.
Keep a spare-parts criticality list (seals, impellers, bearings, filters) based on lead time and production impact, not catalog defaults alone.

FAQ
When is split case preferred?
Higher flow commercial and industrial applications where horizontal split-case maintenance access is valued.
When is end suction used?
Moderate flows and compact pump rooms where footprint and first cost drive selection.
How do suction conditions differ?
Both require adequate NPSH; end suction layouts are sensitive to suction piping geometry.
What maintenance matters?
Impeller and seal access, coupling alignment, and bearing lubrication intervals.
Export documentation?
Curves, test reports, foundation loads, and flange dimensions in imperial and metric.
Can type change after design?
Changing type late often requires pump room resize—lock type during schematic design.
