Feed-water transfer
Move clean or pretreated water to the next process stage.
MCKARLEN VIETNAM · ENGINEERING SOLUTIONS
Water Treatment and RO
Define the pump duty by process stage, water quality, temperature, pressure and materials—without inferring plant capacity or treatment results.
01 · APPLICATION CONTEXT
Application and system context
RO and membrane duty
Review pump duty against the pressure required by process documents.
Process water
Circulate or transfer water between tanks and treatment equipment.
CIP and utilities
Review liquid, temperature, materials and operating cycle.
02 · ENGINEERING CHALLENGES
Common engineering challenges
Unclear water quality
TDS, pH, chemicals, solids and temperature are insufficient for material confirmation.
Changing duty
Valves, membranes, fouling and operating modes change system resistance.
Process boundary
The pump does not represent treatment performance or outlet-water quality.
Fragmented documents
P&ID, datasheet, Pump Schedule and BOQ are not aligned.
03 · REQUIRED PROJECT DATA
Required project data
| Process stage | Pump location in PFD/P&ID, duty and operating mode. |
|---|---|
| Hydraulics | Flow, pressure/head, tank levels, piping and equipment losses. |
| Liquid | Composition, TDS, pH, temperature, solids, chemicals and material requirement. |
| Documents | Pump Schedule, process datasheet, electrical/control data and document requirement. |
04 · ENGINEERING APPROACH
Review and selection flow
- Define the process stage and pump-equipment boundary.
- Normalize hydraulic data and operating modes.
- Review liquid, materials and seal by model.
- Compare HCR, CI/VI or HSS against duty and arrangement.
- Confirm model, documents and items requiring process-engineer approval.
05 · PRODUCT ROLE
Relevant product families
HCR is a vertical multistage stainless-steel centrifugal pump; CI/VI covers suitable inline circulation or transfer duties; HSS is a horizontal multistage stainless-steel centrifugal pump for compatible clean-water duties. Every option requires model and liquid confirmation.
HCR
Use only after duty, liquid, model and configuration are confirmed.
CI / VI
Use only after duty, liquid, model and configuration are confirmed.
HSS
Use only after duty, liquid, model and configuration are confirmed.
06 · RESPONSIBILITY CONTROL
Selection and responsibility boundaries
McKarlen scope
- Review pump duty from supplied process data
- Recommend family/model and required material checks
- Provide model-controlled curve, drawing and datasheet
Responsible-party scope
- Guarantee treated-water quality or RO recovery
- Design the complete water-treatment process
- Publish plant capacity or project results without evidence
07 · DOCUMENT CONTROL
Technical documents and evidence
- Reviewed Pump Schedule / BOQAvailable
- Correct model curveRequest by model
- Model-specific dimensional drawingRequest by model
- Datasheet and material confirmationRequest by model
Document-use principle
Release only the confirmed family, model and revision. Legacy catalogues or documents with obsolete identity are not converted into public downloads.
08 · EVIDENCE GATE
Project evidence
No project record currently meets the evidence and usage-right threshold for publication on this page. No Project Case card is created until that evidence exists.
09 · KNOWLEDGE
Engineering knowledge / FAQ
What is required beyond flow and pressure?
Process stage, liquid, temperature, materials, operating modes and system documents are needed.
Can one pump family cover every stage?
No. Duty, liquid, arrangement and material requirements differ.
Does McKarlen guarantee outlet-water quality?
No. This page addresses pump equipment within supplied data.
Which catalogues are public?
Only approved documents. Model-specific records remain request-controlled.
