Improved plant flexibility and the protection of your existing investments have been one of our key objectives for years. The refurbishment of critical plant components extends the operating life and can often contribute to improved plant performance, minimize the use of costly resources, such as energy and reduce waste of valuable ingredients. Turn your existing homogenizer into a “like-new” machine by having it reconditioned at one of our approved service centers.


With optimum process performance and reliability built-in - SPX FLOW replacement parts represent remarkable value and reliability. SPX FLOW genuine homogenizer replacement parts are designed to fit the equipment specifically, to optimize performance and reduce wear on the homogenizer. The smallest inconsistency in a homogenizer’s valve or valve seat could affect a product's quality or the production lines output directly.


SPX FLOW's pumps, valves, heat exchangers and homogenizers are at the heart of the process plant. Upgrading your homogenizer can raise performance levels, enhance controls or reduce energy consumption.

Due to how critical the homogenizer is to a production line, an untested upgrade could affect the product. SPX FLOW can test homogenizers within the controlled SPX FLOW Innovation Centers. SPX FLOW Innovation Center engineers can replicate a customer’s process and product to accurately test and calibrate any proposed homogenizer solutions.
