This food grade drum pump kit is engineered to meet the stringent demands of modern food production facilities. Here’s the reasons why this drum pump kit is the perfect choice: 

1. Seal-less construction for reduced maintenance

Firstly, with no wetted mechanical seal, maintenance requirements are reduced and the pump can handle dry running (for limited periods). Additionally, this pump is easy to disassemble for cleaning and is ideal for cleanroom and open production areas. Moreover, it’s smooth, polished surfaces eliminate crevices where microbes may grow, ensuring optimal hygiene. 

2. PTFE plug-in bearings for class-leading vibration resistance

Five PTFE bearings support the driveshaft over a wide contact area, therefore minimising vibration and shaft deflection. Furthermore, this extends pump life, reduces maintenance and promotes optimal drainage of residual liquid. 

3. Reversible 316 stainless steel driveshaft

Additionally, the unique heavy-duty, reversible driveshaft effectively doubles service life. Furthermore, the 6mm diameter increases resistance to torsional and axial stress, thereby maintaining precision alignment over time. 

4. Certified safe for food and pharma

This kit is fully compliant with FDA CFR 21 and EC 1935/2004 global hygiene and safety standards. The pump can be used with consumable products, pharmaceutical compounds and cosmetic liquids. Furthermore, this food grade drum pump is suitable for handling pure, non-crystallising, non-abrasive liquids.  

5. Full disassembly without tools

Finally, F 427 S is designed for fast and efficient cleaning. The pump can be stripped down in minutes and re-assembled easily. Moreover, all wetted parts are compatible with sterilisation and autoclave cycles. 

• Food production: Fruit juices with pulp, syrups, dairy products, sauces 

• Pharmaceutical: Sterile solutions, nutrient liquids 

• Cosmetics: Creams, lotions and essential oils 

• Biotech and labs: Sterile buffer solutions, culture media 

• R&D: Hygienic transfer of test media 

• Cooking oils
