PRODUCT SUPPORT
Before you order
Complete item numbers are essential for correct identification.
What should I include in an enquiry?
Include the full model, item number, quantity, fluid, temperature, required flow and pressure. For repairs, add nameplate and component photographs.
Can a photograph confirm the exact configuration?
No. Some configurations share a model image, and reference parts images are identified. The supplied product must be confirmed by the complete item number and technical details.
Can DFIN help identify a repair kit?
Yes. Send the nameplate and maintenance requirements so we can review the pump generation, materials and the relevant air-side or wet-end kit.
