Our experienced Homogenizer Shop also offers completely rebuilt Gaulin homogenizers and high pressure pumps with a limited warranty to give you peace of mind. We have the ability, people, and experience to configure and build a homogenizer that you need for your application – we don’t just offer you whatever configuration suited the previous owner.

Our position as authorized distributors for APV Homogenizers (via SPX Flow) gives us access to OEM parts and factory support, so we can offer expert advice as well as parts & service. If you have an older machine gathering dust as an idle asset in a warehouse, we can offer a full shop-rebuild of your existing Gaulin homogenizer to return it to service. Our 30+ years of experience means that the result is as close to “factory refurbished” as you can get. Our rebuild service includes:
