Saat Anda mencari vertical turbine pump diagram, you are likely evaluating how these pumps work and whether they fit your application—whether it’s moving seawater, supplying a fire protection system, or handling industrial water transfer.
This comprehensive guide provides clear vertical turbine pump diagrams, explains each component, and introduces the LC series vertical turbine pump from Pompa Hunan Durafort—a trusted manufacturer for seawater intake and vertical turbine fire pump applications.
Why a Vertical Turbine Pump Diagram Matters
A vertical turbine pump diagram helps engineers and procurement professionals understand:
- How the pump achieves high flow from deep water sources
- The relationship between the bowl assembly, column pipe, and driver
- Which components contact the pumped fluid (critical for material selection)
- How to specify the correct pump for seawater or fire protection duty
Below is a functional breakdown of a typical vertical turbine pump, followed by how the LC series implements this design.
Vertical Turbine Pump Diagram: Key Components
| Komponen | Fungsi |
|---|---|
| Driver (Motor/Engine) | Mounted on top; provides rotational power (980, 1480, or 2970 r/min) |
| Tinggi Aliran | Houses the stuffing box or mechanical seal; directs flow to piping |
| Pipa Kolom | Shaft enclosure; connects discharge head to bowl assembly |
| Poros Penghubung | Long vertical shaft with bushings; transmits torque down to impellers |
| Perakitan Mangkuk | Contains one or more impellers and diffusers; where pumping occurs |
| Suction Bell/Strainer | Bottom intake; prevents debris entry |
| Impeler (satu atau lebih) | Radial or mixed-flow design; imparts energy to fluid |
| Diffuser (Bowl) | Converts velocity to pressure; guides flow to next stage or column |
Diagram Note: In a multistage vertical turbine pump, multiple bowls are stacked. Seawater applications often use fewer stages (low head), while fire pumps may use additional stages for required pressure.

Broader Material Capabilities (Durafort Pumps)
Beyond standard materials, Durafort also produces pumps in carbon steel, 904L, CD4MCu, and more for highly corrosive or abrasive services.
Vertical Turbine Pump Diagram for Seawater Applications
Seawater intake pumps require special attention to corrosion resistance. The LC series vertical turbine pump diagram for seawater service highlights:
- Wetted materials: SS316L (standard seawater), SS2205 duplex, or SS2507 super duplex for higher chloride resistance
- Low NPSH requirement: Vertical turbine configuration naturally performs well with limited suction head
- Strainer design: Fine enough to prevent marine debris but open enough to avoid excessive loss
Typical Seawater Applications for LC Series
| Industri | Aplikasi |
|---|---|
| Power plants | Cooling water intake from ocean or bay |
| Pabrik baja | Process cooling with seawater |
| Desalination | Feed to reverse osmosis or thermal desalination |
| Marine terminals | Transfer air pemberat |
| Coastal industrial facilities | Raw seawater supply |
Buyer tip: When using the LC pump for seawater, specify SS2205 or SS2507 for the bowl assembly, impeller(s), and line shaft bushings. Cast iron and carbon steel are not suitable for continuous seawater service.
Vertical Turbine Fire Pump Diagram: LC Series in Fire Protection
Vertical turbine fire pumps are essential when the water source is below grade—such as a river, lake, underground tank, or seawater intake. The vertical turbine fire pump diagram differs from a standard vertical turbine pump in several ways:
| Fitur | Standard Vertical Turbine | Vertical Turbine Fire Pump (LC Series) |
|---|---|---|
| Driver | Electric motor | Electric motor or diesel engine |
| Approvals | General industrial | Fire protection listings (varies by region) |
| Peringkat tekanan casing | Standar | Higher (per NFPA 20) |
| Materials for seawater | Optional | Corrosion-resistant alloys required |
| Pengujian | Shop performance | Strict fire pump acceptance testing |
Fire Protection Applications for LC Series
- Coastal refineries and tank farms: Seawater supply to fire water ring mains
- LNG terminals: High-volume fire protection from seawater intake structures
- Power plants: Backup fire water supply from cooling water intake
- Industrial ports: Fire protection for marine loading docks
LC Series Advantages for Fire Service
- Wide flow range (50–8,400 m³/h) covers small to very large fire water demands
- Multiple speed options allow matching pump curve to system requirements
- Materials suitable for seawater (SS2205/SS2507) ensure longevity in corrosive environments
- Vertical configuration saves floor space compared to horizontal split case pumps
How to Read a Vertical Turbine Pump Diagram for Selection
When using a vertical turbine pump diagram to specify an LC series pump, pay attention to:
- Number of stages (bowls) – Determines total head. More stages = higher head.
- Column pipe length – Distance from pump mounting plate to lowest bowl (water level + submergence).
- Drive shaft material – Carbon steel for fresh water; SS316L or duplex for seawater.
- Bearing material – Bronze or Teflon-impregnated for seawater; rubber-lined for abrasive fresh water.
- Discharge head type – Standard (electric motor) or right-angle gear drive (diesel engine for fire pump).
