Vertical Turbine Pump Models
Use this ACCA engineering hub to narrow vertical turbine pump configurations by bowl size, hydraulic duty, impeller type, stage count, materials and application—then confirm the final selection from the required flow, total dynamic head, submergence, setting and driver.
Start With the Hydraulic Duty
A model designation is only the beginning of a vertical turbine selection. The bowl assembly must operate at the required capacity and head while satisfying NPSH, minimum submergence, bowl pressure, shaft loading, driver horsepower and site geometry. For replacement work, ACCA can start from an existing model or bowl designation and engineer the replacement around the actual duty.
Flow
Required GPM establishes the practical hydraulic family and bowl diameter. Larger bowls generally cover higher capacities, while the final operating point must remain within the selected performance curve.
Total Dynamic Head
TDH establishes the pressure the pump must develop. With turbine bowls, additional stages can add head while the basic flow range of the selected hydraulic remains essentially unchanged.
Submergence & NPSH
Minimum water level, drawdown and suction-bell elevation must provide adequate submergence and NPSH margin and avoid vortexing or air entrainment.
Setting & Driver
Column length, lineshaft, thrust, speed, horsepower, motor or gear drive and discharge-head arrangement are engineered as part of the complete pump—not selected independently.
Bowl Size & Hydraulic Range
Vertical turbine bowl diameter is a useful first screening dimension, but it is not a capacity rating by itself. Hydraulic design, speed and impeller trim determine the actual curve. ACCA selections can cover compact deep-well bowls through large wet-pit and high-capacity configurations; the main ACCA VTP range extends to approximately 15,500 GPM and 1,730 ft of head, subject to the selected hydraulic and number of stages.
Small & Medium Bowls
Common in water wells, municipal supply, irrigation and industrial-water systems where casing diameter and setting constrain the pump envelope.
Large Turbine Bowls
Used as capacity increases for municipal intake, industrial water, cooling water, irrigation and other high-flow services.
Mixed-Flow Bowls
Useful where the application calls for higher flow at moderate head. Hydraulic selection balances capacity, head per stage, efficiency and required submergence.
Axial / Propeller Hydraulics
Applied to very-high-flow, low-head duties such as drainage, flood control and large water-transfer systems where a conventional radial turbine hydraulic is not the best fit.

Impeller Types
Enclosed Impeller
A common vertical turbine configuration for clean-water and general industrial service. The impeller operates within diffuser bowls and is selected from the performance curve for the required duty.
Semi-Open Impeller
Available on selected hydraulics where the application benefits from a more open passage or where solids and wear considerations differ from conventional enclosed-impeller service.
Mixed-Flow Impeller
Develops head through both radial and axial velocity components, providing an effective solution for higher-capacity, moderate-head applications.
Axial-Flow Propeller
Moves liquid primarily parallel to the shaft and is suited to exceptionally high capacity at comparatively low head.
Single-Stage & Multistage Selection
One impeller and diffuser bowl form one hydraulic stage. For a selected turbine hydraulic, adding stages increases total developed head while the operating flow remains tied to the bowl’s performance range. Stage count is therefore determined from the required TDH and practical head per stage at the selected duty point—not simply from pump depth.
Single Stage
Appropriate when one bowl stage can produce the required head at the desired capacity and speed.
Multiple Stages
Stages are added in series for higher-head service. Final design must also verify bowl pressure, shaft power, thrust, shaft stretch and driver capacity.
Impeller Trim & Speed
Impeller diameter and operating speed provide additional selection flexibility. Final trim should be based on the manufacturer’s hydraulic curve rather than a nominal model size alone.
Materials of Construction
ACCA can configure the bowl assembly, impellers, shafts and related wetted components around the liquid and project specification. Material selection should account for corrosion, chlorides, abrasion, potable-water requirements and expected service life.
Cast / Ductile Iron
Practical for many clean-water and general municipal or industrial applications when the water chemistry permits.
Bronze
Frequently used for impellers and wear components in water service where improved corrosion performance is desired.
316 Stainless Steel
Available for shafts, impellers and other wetted components where increased corrosion resistance is required.
Nickel-Aluminum Bronze & Special Alloys
Available for selected corrosive, marine and demanding water services when supported by the liquid chemistry and project requirements.
Application-Based Model Selection
Municipal & Deep Wells
Select from required production rate, pumping water level, drawdown, well diameter, TDH, setting and potable-water requirements.
Raw-Water Intake
Consider minimum water elevation, sump geometry, submergence, debris, corrosion and continuous-duty operating range.
Industrial & Cooling Water
Selection may be driven by high duty cycle, system pressure, material requirements, redundancy and compatibility with existing piping and controls.
Irrigation
High-capacity groundwater or surface-water service is selected around seasonal water levels, system pressure, efficiency and available driver power.
Mining & Dewatering
Water chemistry, suspended solids, abrasion, changing water levels and site accessibility can materially affect hydraulic and material selection.
Flood Control & Drainage
High-flow, low-head duties may favor mixed-flow or axial-flow hydraulics rather than a conventional multistage turbine selection.

How to Select From an Existing Model
1. Identify the Existing Pump
Send the manufacturer, complete model, bowl designation, serial number and clear nameplate photographs.
2. Confirm the Hydraulic Duty
Provide actual required GPM and TDH rather than assuming the existing pump was correctly selected for current system conditions.
3. Confirm Bowl & Stages
Record bowl size or designation, stage count, impeller information and any existing performance curve.
4. Confirm Construction
Provide bowl, impeller and shaft materials, column size and length, lubrication arrangement and discharge-head details.
5. Confirm the Driver
Provide horsepower, RPM, voltage, phase, frequency, enclosure and available thrust information.
6. Engineer the Replacement
ACCA reviews the identification data and duty together so the proposed replacement is selected for the installation rather than by model name alone.
