Abrasion Resistant Peristaltic Pumps

This type of design is called a positive displacement pump. Unlike centrifugal pumps, only the hose size or speed can vary the flow rate. The pressure developed is not proportional to the flow. This means that when selected correctly, this pump will deliver a specific flow at a wide variety of pressures. We can change that flow only by using a speed control device such as an inverter drive
Larox Heavy Duty Peristaltic Hose Pumps are ideal for heavy, viscous, abrasive media and especially effective where viscosity can change during a process for example during the life cycle of biomass in effluent treatment plants
The unique Larox contra-rotating roller design means that there is only one compression of the hose for every revolution of the pump. Only Larox uses this technology and it is this reason why the Larox pump is capable of continuous operation, provide the longest hose life possible and have the smallest quantities of lubricant in the pump chamber
It is the friction created by multi-lobe design, adjustable shoes or multiple contact points that defeat the best features of this pump type. Simply explained, if a pump has three lobes, all imparting heat into the hose three times every revolution, it is obvious that the hose life will be compromised and that to try and stem this high wear rate, masses of lubricant will be needed or an oversized pump installed unless you use a Larox Pump
Larox heavy duty peristaltic pumps are developed from years of experience in mineral recovery, mineral processing, metal processing industries, paper and pulp mills, sugar and molasses production and chemical process plants such as TiO2 manufacture, Lime Slurry transfer, Cement and Aircrete Block manufacture
If it can be pumped, there is every chance that somewhere in the world, a Larox Pump has done it, ask us for references for your application
