IDENTIFY THE RIGHT BUILD
Models & configuration
A family or hydraulic size is the starting reference. Include the complete nameplate designation, serial number, materials, seals, drive and connection details when ordering.
Materials & performance
Stainless-steel construction is published for the identified family. Confirm the exact stainless grade, elastomers, mechanical seals, fasteners and motor construction for the selected size.
Provide the duty point, well or basin dimensions, installation depth, water analysis, sand content, power supply, cable requirements and required material execution.
DFIN reviews the operating point together with the suction condition and drive. Supply the fluid properties at both start-up and normal operation so the proposed arrangement can be checked against the appropriate curve.
Application industries
DFIN application links identify duties to discuss, subject to the specified fluid and complete pump configuration.
Typical duties to review
- Deep well pumping / building water supply
- Water supply
- Fire Fighting System
- Mining
- Industrial field
Published design points noted for this family include: stamped stainless steel material, the efficiency can reach 85%; can provide full 316SS anti-corrosion material; Sand content ≤ 50 g/m3. Confirm which points apply to the selected size and execution.
Compatible parts & service
Use the complete VS designation, equipment serial number and nameplate to identify the installed hydraulic, motor and control configuration before ordering a replacement or service part.
For service planning, record operating history and the required drawing positions. Confirm seals, bearings, wear parts, impellers, cables, sensors and control components against the actual build.
Maintenance planning
Use the selected model’s operating manual for isolation, draining, inspection and reassembly. Report leakage, unusual noise, loss of output or visible wear with photographs and the operating history. DFIN can use the equipment identity and drawing positions to prepare a parts enquiry.

PRODUCT & ENGINEERING FAQ
Questions about U-FLO VS
Use these answers to prepare a technically complete comparison and enquiry.
How should U-FLO VS be selected?
Start with the real duty point: fluid, flow, differential pressure or head, temperature, viscosity, solids, suction condition and operating pattern. DFIN then reviews size, materials, sealing and drive.
Are the listed maximum values a guaranteed operating point?
No. They describe independent catalog boundaries for the family or model. The selected point must be checked against the applicable curve, size, speed, fluid and drive arrangement.
What information confirms the complete model code?
Provide the full nameplate designation and serial number plus materials, seal arrangement, ports, drive, motor supply and any special option. A family name alone is not an order code.
Can DFIN help identify service parts?
Yes. Send the equipment identity, drawing position, existing part code, photographs, material and failure description. DFIN can prepare a parts enquiry matched to the installed configuration.
What should be included in the quotation request?
Include quantity, fluid data, operating point, installation, connection standard, available utilities, hazardous-area requirements and delivery destination. For a replacement, include the nameplate and current drawing.
