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
The selected thermal-oil service determines the casing, impeller, shaft-seal and internal material execution. The family designation alone does not specify the complete wetted construction.
State the intended horizontal or vertical arrangement, motor supply, oil temperature, flow, head and suction condition. Verify maintenance access around the close-coupled assembly.
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
- Compact organic heat-transfer oil circulation
- Thermal-oil heating systems with restricted installation space
- Industrial heating duties in chemical, rubber, asphalt, detergent, wood and food-equipment plants
NBT circulates heat-transfer oil. Listing a food-industry heating system does not establish direct food contact or hygienic certification.
Compatible parts & service
Identify rotating parts, shaft seal and casing components using the complete type and serial number. The close-coupled construction must be matched to the existing motor interface.
For a replacement, provide pump and motor nameplates, orientation, base dimensions, pipe connections and the actual thermal-oil duty.
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.

DFIN technical notes for NBT
Shanghai Dfin Pump Co., Ltd. has reorganised the available product facts into practical notes for identification, selection, application review and maintenance planning. These notes support an initial comparison; the final duty point and order code still require project-specific confirmation.
PERFORMANCE NOTE
NBT: how to read the operating range
Maximum family flow: 270 m³/h; Maximum delivery head: 145 m; Maximum outlet pressure: 16 bar; Maximum fluid temperature: 350 °C. These figures describe the documented family or model reference; the usable duty point must be checked against speed, liquid properties, suction conditions and the selected drive.
MODEL IDENTIFICATION
NBT: model and configuration checklist
Identification references include NBT. Use the complete nameplate designation, serial number, connection, materials, seal arrangement and drive details when requesting a replacement or quotation.
APPLICATION REVIEW
NBT: materials and suitable duties
The selected thermal-oil service determines the casing, impeller, shaft-seal and internal material execution. The family designation alone does not specify the complete wetted construction. Typical duties to review include Compact organic heat-transfer oil circulation, Thermal-oil heating systems with restricted installation space, Industrial heating duties in chemical, rubber, asphalt, detergent, wood and food-equipment plants. State the intended horizontal or vertical arrangement, motor supply, oil temperature, flow, head and suction condition. Verify maintenance access around the close-coupled assembly.
SERVICE PLANNING
NBT: maintenance and spare-parts preparation
Identify rotating parts, shaft seal and casing components using the complete type and serial number. The close-coupled construction must be matched to the existing motor interface. Isolate the equipment, follow the applicable maintenance procedure and confirm every replacement item against the installed configuration before ordering.
PRODUCT & ENGINEERING FAQ
Questions about ALLWEILER NBT
Use these answers to prepare a technically complete comparison and enquiry.
How should ALLWEILER NBT 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.
