7 reasons to buy peristaltic pumps
![[Img #68852]](upload/img/periodico/img_68852.jpg)
A peristaltic pump is a positive displacement pump with multiple applications. Its operating system, based on a rotor with rollers or pads attached to a flexible tube, makes this type of pumps have interesting advantages over other industrial pumps with moving parts, such as valves, pistons or closures. If you are thinking about purchasing a peristaltic pump for your company, it will be very useful to know its main advantages and applications.
Versatility
The peristaltic pump offers a high precision in the dosing of fluids of very different nature and different viscosity, which makes it extremely versatile. Among its most common applications are the food industry or cosmetics, with fragile fluids and sensitive to cutting; chemistry and pharmaceuticals, where a peristaltic pump allows a programmable and exact dosage; the health sector, used for dialysis machines or for open heart bypass; mining or ceramic industry.
Suitable for high risk fluids
The system of a peristaltic pump eliminates the risk of leaking, so they are indicated to work with acids or abrasive fluids such as cement or lime, typical in the construction sector; fertilizers or farm waste, typical of the agricultural and livestock industry; hydrocarbons, in the case of the petrochemical industry; or wastewater treatment.
No risk of contamination
Using a peristaltic pump ensures that the fluid never comes in contact with the moving parts of the pump, eliminating risks of contamination, leakage or corrosion. This characteristic makes a peristaltic pump suitable for working in industries such as food, cosmetics and industrial drugstore or oenology.
Constant flow
The absence of moving parts allows a peristaltic pump to deliver a constant flow at different pressures. This feature is an advantage over other industrial pumps, such as membrane pumps, which are not capable of pumping products such as gases when it’s empty or working reliably with solid products.
If you have doubts about the model of peristaltic pump that you must choose ask for advice of a specialized peristaltic pumps manufacturer on the most suitable type according to the flow and the pressure that you need. A peristaltic pump can work with a wide range of flow rates, from 10 to 45,000 litres / hour. High pressure peristaltic pumps, commonly referred to as hose pumps, can operate at up to 16 bar and usually have reinforced tubes and covered with lubricant to prevent abrasion, while low pressure peristaltic pumps, called tube pumps, have dry covers and use rollers.
Dry running capacity
A peristaltic pump does not need refrigerant or lubricant, so it can run dry indefinitely.
Long useful life
The roller that is part of the system of a peristaltic pump does not generate friction, so it is not necessary to use coolant inside the pump. It is one of the most interesting advantages of the use of a peristaltic pump, since it allows extending its useful life.
Low maintenance cost
The operating cost of a peristaltic pump is significantly lower than the rest of pumping technologies currently available on the market. The hose is the only piece of the peristaltic pump that wears out with use and can be replaced quickly and easily. The risk of clogging the filters is also very low and at the end of each batch the pump can be cleaned in a significantly shorter time than other types of pumps, such as gear pumps.
