Pump Testing Software & PLC Automation

Pump testing software and PLC automation are transforming how manufacturers measure pump performance, manage quality control, and document factory testing results. As industrial operations demand more consistent testing procedures, reliable measurements, and traceable documentation, automated pump testing systems are becoming an important part of modern manufacturing workflows.

Traditional pump testing can involve manual readings, handwritten observations, spreadsheets, and repetitive data entry. Although these methods can be effective when carefully managed, they may introduce transcription errors, inconsistent recording intervals, and additional administrative work.

By connecting test-bed instrumentation, programmable logic controllers (PLCs), and digital software, manufacturers can improve data collection, standardise testing procedures, and generate more consistent performance documentation.

At Velotech Solutions, pump testing software and PLC automation form part of a specialised engineering software portfolio designed for industrial pump manufacturers.

In this comprehensive guide, we explain how pump testing software and PLC automation improve accuracy, productivity, efficiency, reporting, and quality assurance in manufacturing.

What Is Pump Testing Software?

Pump testing software is a digital system used to collect, process, display, analyse, and document performance measurements obtained during pump testing.

Manufacturers use pump testing to evaluate whether a pump meets specified operating requirements.

Depending on the pump type and testing procedure, important parameters may include:

Flow rate
Total dynamic head
Suction and discharge pressure
Pump rotational speed
Electrical input power
Shaft power
Pump efficiency
Temperature
Vibration measurements
Net Positive Suction Head (NPSH)

Modern pump testing software can consolidate measurements from multiple instruments into a common interface.

This helps engineers review pump performance, identify deviations, and document results more systematically.

However, software accuracy depends on the quality of instruments, calibration, installation, test procedures, and calculations. Automation alone cannot guarantee accurate measurements.

What Is PLC Automation in Pump Testing?

A Programmable Logic Controller (PLC) is an industrial controller designed to operate machinery and equipment through programmed logic.

In pump testing facilities, PLC systems can coordinate parts of the test sequence and exchange data with connected instruments and supervisory software.

Depending on the installed equipment and configuration, PLC automation may support:

Pump motor control
Valve operation
Instrument signal acquisition
Test sequence coordination
Motor speed control through variable-frequency drives
Operating-condition monitoring
Alarm handling
Equipment interlocks
Communication with supervisory software

For example, a configured PLC may help coordinate pump operation while sensors measure pressure, flow, speed, and other parameters.

These measurements can be transferred to software for display, analysis, and reporting.

Safety-related functions require appropriate risk assessment and engineering design. A standard PLC should not be assumed to replace a dedicated safety controller or independently engineered protective system.

How Pump Testing Software & PLC Automation Work Together

A connected pump testing system typically brings together five important components.

1. Pump Test Bench

The test bench provides the physical arrangement required to operate the pump under controlled conditions.

Depending on the installation, it may include piping, valves, a reservoir, instrumentation, and suitable electrical equipment.

2. Measurement Instruments

Flow meters, pressure transmitters, power analysers, speed sensors, and other devices collect physical measurements during testing.

Instrument selection and calibration are essential for reliable results.

3. PLC and Control Panel

The PLC communicates with connected devices and coordinates the programmed operating sequence.

The control panel may also contain motor starters, drives, communication modules, and protective equipment.

4. Pump Testing Software

The software receives and processes measurement data, allowing engineers to monitor test conditions and review performance calculations.

5. Digital Reports and Records

After testing, results can be organised into reports containing measured values, calculated parameters, test conditions, and relevant acceptance criteria.

The actual capabilities depend on the configured system and available interfaces.

10 Benefits of Pump Testing Software and PLC Automation in Manufacturing

1. Improved Measurement Consistency

Consistent data collection is essential for reliable pump testing.

In manual workflows, measurements may be recorded at slightly different moments or operating conditions.

Connected instrumentation and software allow readings to be captured according to a defined procedure.

This can improve consistency between test runs.

Manufacturing benefit: More repeatable data collection and easier comparison of pump performance.

2. Reduced Manual Data Entry

Manually transferring readings from instruments into spreadsheets or reports takes time.

It also creates opportunities for transcription mistakes.

Automated data acquisition reduces the need for repeated manual entry when instruments are properly integrated.

Manufacturing benefit: Less administrative work and fewer opportunities for data transcription errors.

3. Real-Time Monitoring of Pump Performance

A connected testing system can display live measurements during a test.

Engineers may review parameters such as:

Flow
Pressure
Speed
Power
Head
Efficiency

This helps the test operator understand how the pump is performing under different operating conditions.

Manufacturing benefit: Faster visibility into test conditions and potential abnormalities.

4. Better Pump Performance Curve Analysis

Pump performance curves show the relationship between operating parameters.

Common examples include:

Flow versus Head (Q-H)
Flow versus Efficiency (Q-η)
Flow versus Power (Q-P)

These curves help engineers understand pump behaviour across the tested operating range.

Software can organise recorded points and produce performance graphs using agreed calculation and presentation methods.

Manufacturing benefit: Easier technical evaluation of pump performance.

5. More Standardised Testing Procedures

Manufacturers may need to test numerous pump models and production units.

A structured digital workflow can help establish consistent procedures for test preparation, measurement capture, review, and reporting.

For example, engineers can define:

Pump identification and specification.
Test conditions and operating points.
Required measurement parameters.
Acceptance criteria.
Report requirements.

Manufacturing benefit: Greater procedural consistency and improved traceability.

6. Faster Report Preparation

Manual report generation often involves copying measurements, preparing performance curves, and formatting technical documents.

Pump testing software can help organise this information into predefined reporting formats.

A configured report may include pump identification, test date, measured values, calculations, performance curves, and acceptance observations.

Manufacturing benefit: Reduced repetitive documentation work.

7. Improved Quality Control and Traceability

Pump manufacturing quality teams need reliable records to understand whether tested units meet agreed specifications.

Digital records can make it easier to associate test data with:

Pump model
Serial number
Customer order
Test operator
Date and time
Test conditions
Inspection records

When properly implemented, these records can support technical reviews, quality audits, and investigations.

Manufacturing benefit: Better access to historical testing information.

8. Support for NPSH Testing

Net Positive Suction Head (NPSH) is an important concept in pump engineering.

NPSH testing may be required to understand pump suction performance under specified operating conditions.

A suitably configured testing system can support measurement collection and documentation for NPSH-related procedures.

However, NPSH testing requires appropriate instrumentation, test arrangements, procedures, and calculation methods.

Manufacturing benefit: Structured collection of specialised test information where the necessary hardware and procedures are available.

9. Potential Integration with Other Engineering Systems

Manufacturers often use separate applications for pump selection, manufacturing, quality management, and business operations.

Connecting suitable systems can reduce duplicated data entry and improve information flow.

For example, a pump testing workflow may exchange relevant information with:

Pump selection software
ERP systems
Production records
Customer documentation systems
Quality management applications

Such integration depends on available APIs, communication interfaces, access permissions, and implementation requirements.

Manufacturing benefit: Better coordination between engineering and operational workflows.

10. Improved Operational Efficiency

A properly designed automated test workflow can reduce repeated manual activities and improve the organisation of testing operations.

Potential benefits include:

Reduced time spent recording measurements
Faster access to performance data
More consistent reporting
Easier review of historical results
Reduced dependence on manual document preparation
Better coordination of testing activities

These benefits depend on system design, test-bed instrumentation, staff training, and the nature of the testing process.

Manual Pump Testing vs Automated Pump Testing

Parameter	Manual Testing	Automated Testing
Data Collection	Operator-recorded readings	Connected instrument acquisition
Monitoring	Individual instruments	Centralised live display
Data Entry	Manual recording	Potentially automatic
Report Preparation	Spreadsheet or manual documents	Configured digital outputs
Performance Curves	Manually prepared	Software-generated
Traceability	Paper or separate records	Structured digital records
Procedure Consistency	Dependent on operators	Supported by programmed workflows
Initial Investment	Often lower	May require integration investment
Maintenance	Instrument and procedure upkeep	Hardware, software and calibration upkeep

Both methods can produce accurate results when the equipment, measurement process, and personnel are appropriately managed.

The primary advantage of automation is that it can improve workflow consistency and reduce repetitive manual operations.

Understanding Pump Testing Standards: ISO 9906 and ANSI/HI 14.6

Pump performance testing is guided by recognised technical standards.

ISO 9906:2012

ISO 9906:2012 addresses hydraulic performance acceptance testing for rotodynamic pumps, including centrifugal, mixed-flow, and axial-flow pumps.

It defines test procedures and acceptance grades used to evaluate hydraulic performance against specified guarantees.

Testing must follow the applicable standard requirements and agreed acceptance criteria.

ANSI/HI 14.6-2022

ANSI/HI 14.6-2022 addresses hydraulic performance acceptance testing for rotodynamic pumps.

It includes procedures and acceptance criteria relating to performance testing, NPSH, hydrostatic pressure testing, data recording, and reporting.

Why Testing Standards Matter

Standards provide a framework for consistent measurement procedures and technical evaluation.

However, using pump testing software does not automatically establish compliance with ISO or ANSI/HI requirements.

Compliance depends on the complete testing arrangement, instrumentation, measurement uncertainty, calculations, documented procedures, and acceptance conditions.

Manufacturers should confirm the applicable standard, edition, and contractual requirements before conducting acceptance tests.

Key Performance Parameters in Pump Testing

Understanding the measured and calculated parameters is essential for interpreting test results.

Flow Rate

Flow rate represents the volume of liquid passing through the pump per unit time.

Common units include cubic metres per hour (m³/h) and litres per second (L/s).

Total Dynamic Head

Head represents the energy transferred to the fluid per unit weight, expressed as an equivalent height of liquid.

It is calculated using the appropriate pressure, velocity, and elevation measurements.

Power

Power measurements help engineers understand the energy required to operate the pump.

The distinction between electrical input power and mechanical shaft power is important when calculating efficiency.

Pump Efficiency

Pump efficiency is calculated by comparing hydraulic output power with mechanical shaft input power.

For water and other suitable fluids:

Hydraulic Power (W) = Density × Gravity × Flow Rate × Head

Pump Efficiency (%) = (Hydraulic Power ÷ Shaft Input Power) × 100

Accurate efficiency calculations require consistent units and suitable measurement methods.

NPSH

NPSH is used in assessing suction conditions and the risk of cavitation.

Specific NPSH test procedures should be selected according to the pump application and applicable standard.
