Peristaltic pumps are one of the most used types of industrial pumps today, thanks to their excellent performance and extraordinary versatility to work with all types of fluids, even abrasive or corrosive, without suffering wear. However, as in any industrial equipment, if you want to extend its service life to the maximum it is essential to carry out a proper maintenance. What are the recommended operations for industrial peristaltic pumps? How often should they be done? Do we need specialized personnel to carry them out? Read on and discover how to keep these industrial pumps always in optimal condition.

How long do peristaltic pumps last?

The secret the great durability of peristaltic pumps lies in their design. Unlike other industrial dosing pumps, hose pumps lack valves, washers or mechanical seals, which makes the hose, in direct contact with the fluid, the only piece susceptible to deterioration. This fact makes its maintenance extremely simple and much cheaper, since, in case of breakage, we will only need to change the hose so that our peristaltic pump works again at full capacity.

In addition, industrial pump manufacturers agree to periodically check the lubrication of the hose and rollers. In low-pressure hose pumps, for example, it is advisable to perform this check approximately every 300 hours of operation, although the periodicity of this review depends on the specific characteristics of each model. In case of doubt, it is always advisable to consult with your industrial pump manufacturer on the amount or type of lubricant suitable for each type of pump.

As for the reducer, depending on the model, the pump may have permanent lubrication, so no additional maintenance operation is necessary, or it may be necessary to change the oil periodically, always following the manufacturer’s maintenance instructions.

Replacing hoses in peristaltic pumps

The service life of peristaltic pumps hoses cannot be determined a priori. High temperature products or pump cavitation, for example, can shorten their operating life. Using an improper lubricant will also affect the durability of this element, so it is always advisable to use the lubricant recommended by our pump  manufacturer. Although in the current market you can find lubricants with a wide range of prices and qualities, before choosing consider that choosing a cheaper and lower quality product can cause damage to the pump, whose repair budget will be much more expensive.

The disassembly and assembly of the hose in industrial peristaltic pumps is a very simple process and can be carried out ‘on site’ quickly. Although this operation does not require specialized personnel, it is important to know the pump’s operating system in depth and follow the indications provided by your hose pump manufacturer thoroughly. The process depends on the type of pump in question, but basically, it consists of the disassembly of the suction and discharge pipes and the front cover, to remove the pump body and proceed to replace the hose.

In addition, industrial peristaltic pumps, such as the ones you can find in the online store Bombas Boyser, can also include optional devices that allow extending the life of the system and facilitate its maintenance, such as pulsation dampers, breakage detectors or spacers for hose change, which allow replacing this part without removing the entire pipeline.
