Hose pump elements

NR Metering hose

Overview

Natural rubber (NR) Metering hose elements

Manufactured for high consistency and repeatability. Suitable for fluid metering and heavy duty applications. Outstanding abrasion resistance from extruded inner layer. Machined surface finish to dimension. Maximised pumphead life by low stress on bearings.

Examples of compatible media:

  • Slurries and sludges with up to 80 % solids
  • Magnesium oxide and titanium dioxide
  • Water-based paints and pigments

Chemical Compatibility Guide
