ALLWEILER NBT — Close-coupled thermal-oil centrifugal pump — Product series

PRODUCT RECORD

Recorded specifications and identification

This is a series, model or configuration reference. Family maximum values are independent catalogue limits and must not be combined as a guaranteed operating point. It is not a stock or delivery promise.

SELECTION AND SERVICE

Configuration and operating conditions

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.

Published family limits are independent maxima and do not describe one simultaneous operating point.

• 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.

• Use the complete nameplate designation, serial number and component item number to confirm the equipment revision and fit.
• Check the fluid, temperature, viscosity, required flow, pressure, suction conditions and connection standard for the actual application.
• Confirm all wetted materials, seals, diaphragms and other selected components against the operating conditions. A material name alone does not establish suitability.
• For replacement parts, include photographs of the old part, its assembly position and relevant dimensions.
