Tapflo UK’s 3-Inch Diaphragm Pumps for Demanding Applications

High Capacity & Efficiency:

Max flow rate of 820 l/min, making it perfect for high-volume fluid transfer. This increased capacity reduces operational time and enhances productivity

Superior Chemical & Abrasion Resistance

Made from Polyethylene (PE) or PTFE, the pump handles even the most aggressive chemicals (acids, alkalis, solvents) and abrasive slurries with ease

Low-Maintenance Design

With fewer components than traditional pumps, the design minimises service costs and downtime. Easy access to parts makes maintenance quick and simple

Self-Priming Operation

The diaphragm technology allows for self-priming, even in systems with air pockets, delivering reliable performance across a variety of fluid types in difficult environments

Versatility Across Industries

Ideal for a wide range of applications, from chemical handling and food processing to water treatment and mining

Sanitary Design Options

Available in sanitary configurations for food, beverage, pharmaceutical, and cosmetic industries, well suited to CIP processes as the pump can be thoroughly cleaned without disassembly

ATEX Certification

ATEX-certified versions are available for explosive environments

Long Service Life

PE and PTFE materials provide superior wear resistance, with PE being 6 – 7 times more wear-resistant than polypropylene (PP), making it suitable for handling abrasive slurries and extending the pump’s life

Lubrication-Free Operation

This Diaphragm Pump operates without the need for lubrication, reducing maintenance and increasing reliability by eliminating common lubrication issues
