VERDERFLEX HOSES industrial peristaltic hose pumps - Hoses

Some industrial hose pumps in today’s market have machined exteriors, a process generally employed to achieve an equal wall thickness. In comparison, the unique Verderflex® production process is so precise that the exact wall thickness and outer diameter tolerances are maintained at each and every point. For this reason Verderflex® hoses do not have to undergo this additional process of external machining. When Verderflex® hoses are tested alongside their competitors, results indicate that there is no additional friction loss due to the wound surface. The textured surface actually creates micro-pockets of lubricant which promotes even lubrication coverage which results in longer hose life . 12 standard hose sizes from 5mm (3/16”) to 125mm (5”) All hoses are designed to maximize hose life by increasing the the hoses’ fatigue strength Hoses are available in Natural Rubber (NR), Nitrile Buna Rubber (NBR), Food Grade NBR (NBRF), EPDM and Hypalon® (CSM) Hoses have colour coded identification tapes bonded into the outer surface during manufacture to clearly identify material type
	NR - Natural Rubber Suitable for use with lightly corrosive chemicals, highly abrasive slurries and inorganic products. Temperature range -20°C/-5°F to +80°C/+175°F
	NBR - Nitrite Buna Rubber The hose is particularly suitable for use with oily or fatty products and with organic materials. Temperature range -20°C/-5°F to +80°C/+175°F
	Food Grade - NBRF The NBRF hose has an FDA approved food grade liner for use in hygienic applications. Temperature range -20°C/-5°F to +80°C/+175°F
	EPDM This hose is suitable for corrosive chemicals and inorganic products. Solid construction, made totally from EPDM rubber. Temperature range -20°C/-5°F to +100°C/+210°F
	Hypalon - CSM The CSM or Hypalon® hose is used to pump highly corrosive products. The hose has a CSM inner liner and an SBR/NR outer cover. Temperature range -20°C/-5°F to +85°C/+175°F

The successful use of hose pumps in a number of situations led Verder to develop a hose with an enhanced construction. Hoses in peristaltic pumps generally fail due to fatigue between the rubber layers and the reinforcement layer. Verder hoses are specifically designed and manufactured to maximise fatigue resistance, resulting in an extremely long hose service life.

A peristaltic hose pump flow rate is determined by the hose’s internal diameter and the pump’s rotor speed. In turn the hose’s wall thickness compared to its diameter and its number of reinforcement layers create the hose’s restitution after compression which creates a vacuum in the hose and hence the pump’s priming mechanism. By combining these facets with an optimum textile reinforcement construction, the Verderflex hose generates a discharge pressure up to 16 Bar/230 PSI for all pump sizes whilst maximizing the hose’s longevity.
