Choose between a horizontal split case and a vertical turbine fire pump mainly from water-source geometry, suction conditions, required duty, site layout, maintenance access, driver arrangement, and approved listing. A horizontal split case pump normally needs a dependable flooded or otherwise acceptable suction arrangement and offers accessible casing inspection. A vertical turbine pump is suited to wet pits, wells, or tanks where the pumping element must remain submerged below the lowest usable water level. Keep the calculation and acceptance record with the final project documents so future tests use the same basis.
Sicherheit und Geltungsbereich: Feuerlöschpumpen und deren Antriebe sind lebensrettende Einrichtungen. Arbeiten an Hydraulik, Elektrik, Diesel, Kraftstoff, Batterie, Druck, rotierenden Geräten, Prüfungen und Betriebsstörungen müssen dem aktuellen genehmigten Entwurf, den Herstelleranweisungen, den geltenden Normen und der zuständigen Behörde entsprechen. Dieser Leitfaden erläutert den ingenieurtechnischen Entscheidungsweg; er berechtigt nicht zu Änderungen vor Ort, Umgehungen oder zum Betrieb durch unqualifiziertes Personal.
Start with the water source
Define tank, reservoir, wet pit, well, or main; record minimum usable level, variation, sediment, water quality, and access. Treat this as a system condition rather than an isolated component choice. Identify the source of every input, the unit used, the operating condition it represents, and the person responsible for approval. If information is preliminary, mark the assumption and test how the decision changes at a conservative boundary. This prevents a neat calculation from hiding an uncertain water level, pressure, valve position, driver condition, or simultaneous demand.
For horizontal split case vs vertical turbine fire pump, verify this section against the selected pump curve, the actual site arrangement, manufacturer instructions, and the current requirements accepted by the authority having jurisdiction. Check the installed condition as well as the drawing because pipe routes, elevations, supports, controls, and access often change during construction. Record the result in a form that can be repeated during commissioning and later inspection. Do not change a safety-critical setting or isolate fire protection without the approved impairment and restoration process.
Compare suction conditions
A split case pump relies on a properly designed suction pipe and available pressure. A vertical turbine places bowls below water but requires correct submergence and intake design. The most useful evidence is measured or approved project data, not a copied rule of thumb. Identify the source of every input, the unit used, the operating condition it represents, and the person responsible for approval. If information is preliminary, mark the assumption and test how the decision changes at a conservative boundary. This prevents a neat calculation from hiding an uncertain water level, pressure, valve position, driver condition, or simultaneous demand.

Match flow and head
Use certified curves for the required duty and test range. Confirm driver power, speed, pressure limits, and suction or submergence criteria. Review this condition at normal, test, and credible abnormal states before procurement.

Review footprint and structure
Split case units need horizontal floor space and pipe access. Vertical turbine units need a pit or well, vertical clearance, discharge head support, and a removal path. The design team should turn this point into a traceable calculation or drawing note. Identify the source of every input, the unit used, the operating condition it represents, and the person responsible for approval.

Praktische Entscheidungstabelle
| Entscheidungsfaktor | Horizontal split case | Vertical turbine |
|---|---|---|
| Typical source arrangement | Flooded or acceptable suction piping | Wet pit, tank, reservoir, or well |
| Pump element location | In pump room on base | Bowls submerged below water |
| Space demand | More horizontal floor space | More vertical and lifting clearance |
| Suction design focus | Pipe velocity, loss, fittings, air | Submergence, intake flow, vortices |
| Wartungszugang | Casing split gives rotor access | Column and bowls may need lifting |
| Structural need | Base and aligned piping | Discharge head, pit, column support |

Split casings can provide rotor access without removing all piping. Vertical turbines may require lifting the column and bowl assembly from the source. Treat this as a system condition rather than an isolated component choice. Identify the source of every input, the unit used, the operating condition it represents, and the person responsible for approval. If information is preliminary, mark the assumption and test how the decision changes at a conservative boundary. This prevents a neat calculation from hiding an uncertain water level, pressure, valve position, driver condition, or simultaneous demand.

Both arrangements can use approved electric or diesel drivers in suitable configurations. Review shafting, gear drives where applicable, alignment, cooling, and controls.

Häufig gestellte Fragen
Is a vertical turbine pump always better for a tank?
No. The choice depends on tank geometry, minimum level, duty, access, structure, maintenance, and approved design.
Can a split case pump lift water from below?
Use only an acceptable suction arrangement supported by hydraulic analysis and applicable requirements; avoid unsupported assumptions.
Welche Pumpe ist einfacher zu warten?
Split case internals are often more accessible in the room, while vertical turbine maintenance needs lifting access; actual design matters.
What intake information does a vertical turbine supplier need?
Provide pit or tank geometry, water levels, submergence, approach flow, sediment, water quality, duty, driver, and site constraints.
