Flux Pump Hose Connectors | DN19 Hose Fittings for JuniorFlux and CombiFlux

In any pump system, the integrity of the connection between pump and hose is crucial. These connections are designed for use with the JuniorFlux and CombiFlux pump series, and are manufactured to precise standards, ensuring leak-free operation, chemical compatibility and operational safety. Each connector features a DN19 hose tail, a female union nut and a PE flat seal to guarantee a leak-free, re-usable connection. These components are engineered to resist loosening or leakage under pressure and vibration. By selecting the correct material to match the pump tube (polypropylene, PVDF, or stainless steel), compatibility with the media being transferred is assured, whether it’s water, acids, alkalis, or oils. Whether you're transferring chemicals in a pharmaceutical lab or dispensing fluids from an IBC, Flux pump hose connectors offer the safe, efficient connection you can trust.

A hose fitting, or hose connector, is a mechanical device that joins a hose to a pump, tank, pipe, or other equipment. It is a critical interface in any fluid handling system, ensuring an airtight and liquid-tight seal between the hose and the equipment. Therefore, the quality and integrity of this connection is essential.

In pumping applications, hose fittings must withstand both internal pressure and external mechanical stress, such as bending, compression, vibration, or thermal expansion. Flux pump hose connectors are specifically designed to handle these challenges. The female union nut creates a secure attachment to the pump outlet, while the PE flat seal provides a durable, re-usable contact surface to eliminate leaks. In addition, the DN19 hose tail is compatible with standard industrial hoses, for integration with a range of systems.

The best pump hose connectors are those that are durable, re-usable, chemically compatible and prevent leaks in demanding fluid transfer environments. Hose connections should be a fit-and-forget item. To determine the most suitable connector, it is essential to consider:

Hose diameter – Matching the connector tail outer diameter (e.g., DN19) to the hose bore (I.D.) ensures optimal sealing.

Material compatibility – The connector material must match the pump material to ensure chemical and temperature resistance. Flux offers variants in polypropylene, PVDF and stainless steel to suit our drum pump range.

Seal integrity – Replaceable, re-usable PE flat seals are a chemically-resistant, reliable barrier against leaks.

Connection type – The female union nut simplifies installation and removal, making them ideal for systems requiring regular maintenance or hose changes.

Flux pump hose connectors have been widely tested in every conceivable pumping application. Their compatibility with the JuniorFlux and CombiFlux pumps makes them the first choice for safe drum and IBC fluid transfer. Furthermore, hose connections are also available for Flux F 400 and F 500 series pumps.
