AFX
HOSES

At the heart of every AFX peristaltic pump lies a heavy-duty peristaltic hose specially developed to work hand in hand with the pump roller technology installed in the AFX PUMP SERIES. We stock a comprehensive range of hose materials for each pump to be compatible with the unique chemical and abrasive characteristics of every application. A carefully designed and manufactured hose element is the single most vital component for the performance durability and efficiency of any peristaltic pump. To ensure a good pump you must have a good hose, and this is where AFX excels. Each hose we supply is built under stringent quality control measures, using high-quality, compounded rubbers, reinforced with four individual layers of braided nylon carefully set at optimum angles. Once cured, the outer diameter of each hose is precision machined to exacting tolerances ensuring a perfectly sized hose. An accurately sized hose ensures perfect compression, which eliminates internal slip (which reduces pump efficiency and allows for the abrasive slurries to prematurely destroy the hose).

DESIGNED AND MANUFACTURED TO PERFECTION

Utilising design tools such as Finite Element Analysis (FEA), backed up by physical tests and theoretical calculations, our hoses are designed to perfection – right down to the position of the reinforcing layers, the braid angles, cord thickness, and the thickness of the surrounding rubber. The roller geometry and the profile of the pump housing are all designed and engineered to optimise the performance of the pump hose. To ensure a good repeatable and consistent hose life, you must have a hose built and machined to exacting tolerances. To us, the ISO standards are not good enough. All our hoses exceed the requirements set out in ISO 1307 and DIN7715.

AVAILABLE HOSE LINER MATERIALS

NATURAL RUBBER (NR)

HOSES FOR USE IN OTHER MANUFACTURERS’ PUMPS

So confident are we about the quality of our hose, that we will supply hoses produced to original tolerances for many of the major peristaltic pump manufacturers pumps. We have successfully reduced operational costs for a large number of customers by using our hose in their existing peristaltic hose pumps.
