Raw-water transfer
Use after suspended matter and liquid condition are checked for compatibility.
Pump equipment for water systems
Industrial Water Supply
Engineering guidance for water transfer, distribution and circulation duties in factories, MEP projects and water-treatment systems. Selection is reviewed against the required flow and head, suction conditions, liquid properties, operating mode and available project documents.
Applications
Typical Applications
Identify the system duty before selecting a pump family and model.
Clean-water transfer
Supply or transfer clean water between stages and points of use.
Process-water supply
Deliver water to equipment at the required duty point.
Tank-to-tank transfer
Review elevation, route losses and operating sequence.
Factory utility water
Support washdown, cooling and shared utility-water duties.
Cooling-water support
Supply or circulate after arrangement and temperature review.
Stable-pressure supply
Confirm demand, source pressure and control scope.
Factory circulation systems
Maintain circulation in compatible technical-water systems.
MEP technical water
Coordinate with the Pump Schedule, BOQ and installation space.
Water-treatment feed and transfer
Use after liquid and material requirements are confirmed.
Input risks
Common Project Problems
Items that should be resolved before the pump configuration is confirmed.
Demand changes over time
Demand may vary by shift, process stage or operating period; one isolated value is not a complete selection basis.
The duty point is incomplete
Flow and head must be reviewed with source conditions, outlet pressure and losses across the complete route.
Suction conditions are unclear
Source level, inlet pressure, transfer distance and unstable inlet conditions need review.
Pipeline losses are incomplete
Valves, fittings, equipment, pipe diameter and static elevation all affect total dynamic head.
Standby requirements are undefined
Pump quantity, alternation and standby duty depend on the required continuity of service.
Water properties are not confirmed
Temperature, suspended matter, contamination and material requirements must be checked before selecting a family.

Review sequence
Recommended System Approach
A practical workflow for turning project information into a reviewable pump-selection request.
Separate demand cases
Define normal demand, peak demand and processes that may operate simultaneously.
Review the source and suction condition
Confirm source level or pressure, transfer distance and any unstable inlet condition.
Establish the duty point
Combine flow, static elevation, required outlet pressure and losses across the complete route.
Confirm liquid and material requirements
Review temperature, suspended matter, contamination and material needs before family selection.
Define the operating configuration
Evaluate pump quantity, alternation, standby duty and the required control scope.
Confirm the model and submittal
Select against approved inputs, then issue the relevant curve, drawing and technical documents.
This is a project-preparation and technical-review workflow. It does not replace complete system design or the consultant’s design responsibility.
Relevant pump families
Relevant Product Families
Each family has a distinct system role. The final model is confirmed only after the project inputs are reviewed.
CI / VI Series
Inline pumps for compatible water-supply, transfer or circulation duties where the piping arrangement and installation space suit a horizontal or vertical inline configuration.
HCR Series
Vertical multistage stainless-steel centrifugal pumps for clean water and compatible industrial-water duties where a multistage or higher-head approach is required.
Application conditions
Selection Boundaries and Limitations
Keep solution scoping, pump-family selection and final model confirmation clearly separated.
Not a complete design service
This page supports solution scoping; it does not confirm a model when project inputs are incomplete.
No direct substitution
CI / VI and HCR have different roles and must not be selected on size or motor power alone.
Review raw-water quality
Suspended matter, contamination and liquid properties must be checked before a pump is confirmed.
Separate wastewater duties
Wastewater and solids-handling applications are outside this page.
Model-specific parameters
Temperature, pressure, materials, power supply and curves are confirmed by model.
Configuration follows operation
Pump quantity, standby duty and controls depend on the operating profile and project scope.
Controlled documents
Technical Documents and Support
Use approved public documents where available; model-specific submittals follow a technical request and project review.
CI / VI Catalogues
Publicly available
Access controlled public documents through the CI / VI Product page.
HCR Catalogue
Available on request
Supplied through a technical-document request and project review.
Curves and drawings
Project review required
Confirmed for the selected model, frequency, configuration and duty point.
Material information
Project review required
Confirmed against the liquid, temperature and selected construction.
Installation guidance
Available on request
Supplied according to pump type, piping arrangement and maintenance access.
Equipment evidence
Equipment References
Equipment-reference records are governed by application, industry, approved location and McKarlen equipment-supply or product-support scope. Only records with sufficient technical evidence and approved image rights are made public.
Engineering knowledge
Engineering Knowledge
Three practical entry points for preparing a more complete project request.
Pump-selection data guide
Review the information required before submitting a selection request.
Duty point and suction conditions
Understand the factors that affect flow, head and stable operation.
Model-specific documents
Identify when catalogues, curves, drawings, material information or installation guidance are required.
Engineering FAQ
Engineering FAQ
Answers focused on project inputs, selection boundaries and document control.
Does every industrial water-supply system use the same pump configuration?
No. Demand, source condition, piping, liquid properties, operating schedule and redundancy requirements vary by project.
When should CI / VI be reviewed, and when should HCR be considered?
CI / VI is relevant to suitable inline duties. HCR is considered for clean water or compatible industrial water where a multistage approach is required.
Can pump selection start with flow alone?
It should not. Total head, suction conditions, liquid information, operating schedule and basic piping data are also required.
Can CI / VI or HCR handle raw water directly?
Only after suspended matter, contamination and liquid properties are confirmed as compatible with the proposed construction.
What should total dynamic head include?
The review should include static elevation, required pressure at the point of use, pipe and equipment losses, and the source condition.
When is a standby pump required?
The decision depends on production continuity, maintenance strategy, allowable shutdown time and the agreed project responsibility.
Can curves and drawings be requested before the model is finalised?
A request can be submitted, but the correct document set is issued after the duty point, model, frequency and configuration are confirmed.
Project enquiry
Do you have a Pump Schedule, BOQ or operating data?
Submit the available documents with the required flow and head, liquid, temperature, power supply, material requirements and project location for technical review.
