Flowrox™ FXM metering pumps
FXM pumps for accurate metering

Flowrox™ FXM metering pump is ideal for chemical dosing applications which require accurate metering. To optimise metering performance, we offer FXM2 and FXM3 series pumps with improved performance. As flow control specialists, we know it is a big advantage to have only one wear-resistant part (tube assembly) in contact with corrosive or abrasive mediums. Flowrox FXM pump has low consumption of spare parts, reduces maintenance and downtime, improves process performance and provides accurate dosing.
Benefits and features
Accurate and safe metering
Positive displacement provides same output on every cycle
Versatile system connectivity
Diverse programming options and controllability
Safety
Maintenance mode for safe tube changing.
Technically improved Utilizes latest technology for highest reliability
Improved performance
To optimise metering performance, we offer FXM2 and FXM3 series pumps with improved performance. Compared to the previous generation, FXM pumps have expanded logic programming and functionality and also higher capacity. Maximum flow of the FXM2 model reaches up to 176 l/hr (46.5 GPH) and FXM3 up to 840 l/hr (221.9 GPH). Working pressure of FXM2 goes up to 8.6 bar (125 psi) and FXM3 up to 4.5 bar (65 psi). They can also withstand fluid temperature up to 54° C (130° F). Combined with accurate metering and a selection of different tube materials, the FXM pumps are an ultimate choice for chemical dosing applications.

Both models, FXM2 and FXM3 pumps have a handle and are easy to carry.
Technical specifications
Reliability and safety improved
Accurate and reliable operation
Positive displacement of the tube bore with zero slip provides same output volume on every cycle. There is no variation due to the discharge pressure condition. The compression point of the tube acts as
self-cleaning check valve without clogging risk providing clear flow path with no possibility for vapour lock.
