Enquire about this productProduct Overview
DESMI ROTAN GP41EM-1U2B2 is a complete-model reference used in the DESMI ROTAN Pump Selection Users Manual as an item-number search example. DFIN publishes this page for model identification, replacement enquiries and duty review. The example designation does not by itself establish current stock or a guaranteed operating point.

Construction and Configuration
ROTAN GP uses cast-iron construction for general clean, non-abrasive liquid transfer. The complete model code identifies configuration details such as orientation, sealing, lubrication and bearing materials. Final material compatibility must be checked against the actual liquid.
Typical Applications
Typical GP duties include clean oils, glycol, vegetable oil, lubricating oil, compatible solvents, waste oil and other non-abrasive liquids, subject to viscosity, temperature and material-compatibility review.
Selection Information Required
For a replacement or new duty, send the complete nameplate designation, serial number if available, liquid, viscosity at start-up and operating temperature, required flow, differential pressure, suction condition, installation arrangement, motor supply and quantity.
Source and Verification
Primary reference: DESMI ROTAN Pump Selection Users Manual and DESMI ROTAN GP product documentation. DESMI notes that internal CFG numbers are not order numbers. DFIN therefore confirms the current item number / complete configuration before quotation.
