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

Petrochemical-duty construction; the shared HD/PD stock designation must be checked against the project build.

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.

This page preserves an official DESMI full-model string. Availability and a new order configuration still require current verification.

• 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.

• 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.
