Hygienic transfer of low viscosity liquids

Firstly, this pump is the ideal solution for hygienic transfer of low viscosity products from drums, barrels and IBC containers. F 427 is a seal-less drum pump food grade solution, incorporating unique plug-in PTFE bearings (including the lower bearing housing) to facilitate rapid disassembly for cleaning or de-contamination.

In addition, you can sterilise all disassembled parts in a high-temperature parts washer, or autoclave. The pump is also suitable for Clean-In-Place (CIP) and Sterilise-In-Place (SIP) protocols, where applicable. 

Stainless steel 316 Ti

Additionally, the use of stainless steel 316 Ti, known for its enhanced resistance to pitting and crevice corrosion, ensures this pump endures repeated sterilisation without degradation. The pump tubes are polished to a surface roughness of 0.4 microns, with welds being treated to 1.6 microns. 

Furthermore, the design eliminates any dead spots where product residue could accumulate, helping to reduce the risk of bacterial growth and product contamination. 

Versatile pump for range of applications

This pump is versatile, handling a wide range of liquids, including those containing suspended soft-solids such as pulp, soup or spices. However, the pump is not suitable for transferring highly flammable liquids, or media containing a large quantity of hard solid particles.

Finally, the sealed bearing and two radial shaft seals protect the motor coupling from ingress of vapours and liquids.
