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

Stainless-steel chemical-duty ROTAN construction; exact wetted materials and seal details follow the verified designation.

Use the exact model and item number for identification. For a new order or replacement, confirm the duty point, fluid, viscosity, temperature, differential pressure, connection, seal, drive and current availability in the DESMI Selection Program or from the installed pump nameplate.

This page preserves a DESMI-documented model string. Current availability and a new-order configuration still require verification.

• Quote the complete model and item number when available.
• For installed equipment, include a nameplate photo and serial number to distinguish 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.
