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; bush, seal and elastomer materials require chemical-compatibility review.
Provide liquid, concentration, start-up and operating temperature, viscosity, required flow, differential pressure, suction condition, connection standard, installation orientation, hazardous-area requirement, motor/drive supply and delivery destination. Confirm the complete order code before quotation.
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
- Compatible acids, alkalis and specialty-chemical transfer
- Resins, soaps, shampoo, polymer solutions and other compatible chemicals
Compatible parts & service
Use the complete nameplate designation and serial number when identifying replacement pumps or service parts.
DFIN verifies the selected size, materials, bearing arrangement, shaft seal, connection standard and drive against the actual duty before quotation.
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 DESMI ROTAN CD26 Inline Flanged Packing
Use these answers to prepare a technically complete comparison and enquiry.
How should DESMI ROTAN CD26 Inline Flanged Packing 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.
