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

Cast-iron construction; final bearing, seal and drive details follow the complete verified designation.

Use this full designation as an identification reference. For a new order or replacement, confirm duty point, fluid, viscosity, temperature, differential pressure, connection, seal, motor/drive and current availability with the DESMI Selection Program or nameplate data.

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

  • Configuration-specific transfer duty — final application review required

Compatible parts & service

Quote the complete model and DESMI item number when requesting a replacement or service review.

For installed equipment, add a nameplate photo and serial number to avoid confusing similar suffix combinations.

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 GP26EFM-1U3B2

Use these answers to prepare a technically complete comparison and enquiry.

How should DESMI ROTAN GP26EFM-1U3B2 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.
