Introduction of Peristaltic Pump

The peristaltic pump is a kind of leak free positive displacement pump that operates by squeezing and releasing a flexible hose to generate flow. It uses a rotating mechanism with rollers or shoes that compress the tube against a fixed housing or track, creating a series of occlusions that move along the length of the tube. As the occlusion progresses, it pushes the fluid trapped in the tube forward. Due to the special working principle, users also call it hose pump, tube pump or squeeze pump.

SeFluid is a leading peristaltic pump manufacturers in China.  We adhere to the highest product quality standards. In addition, during the lifetime use of our products, we ensure complete after-sales technical support to serve users with confidence and satisfaction.

Principle of Peristaltic Pump

Video abspielen über Peristaltikpumpenschlauch | SeFluid

On its rotor, there are two or more pressure rollers or sliding shoes. These rollers or shoes alternately squeeze the hose to divide the hose into different sections of enclosed space. Consequently, there is vacuum appears in the hose. The vacuum generates suction force to suck the medium into the hose and then squeeze it out. This working process is similar to the peristalsis of human intestines. Therefore, the pump is called peristaltic pump, hose pump or squeeze pump.

What fluidity range peristaltic pump can handle?

From water to almost powder like material, it can handle the widest fluidity range than other kinds of pump. Especially for those medium without flowability (like mud), a peristaltic hose pump is your best choice (the percentage is the liquid content of the medium).

What fluid types peristaltc pump can handle?

Peristaltic pumps are known for their versatility and ability to handle a wide range of fluids. They are commonly used in various industries and applications due to their gentle pumping action and the ability to handle both corrosive and non-corrosive fluids. Here are some fluid types that peristaltic pumps can typically handle:

Wide liquid range

Peristaltic pumps are suitable for handling a wide range of liquids, including water, chemicals, solvents, acids, bases, oils, slurries, suspensions, and viscous fluids.

Abrasive Fluids

Peristaltic pumps are suitable for handling a wide range of liquids, including water, chemicals, solvents, acids, bases, oils, slurries, suspensions, and viscous fluids.

Peristaltic Pump is Ideal for Shear-sensitive Fluids

Peristaltic pumps are gentle and provide low shear pumping, making them suitable for handling shear-sensitive fluids such as pharmaceuticals, biotech products, food and beverages, and delicate emulsions.

High-viscosity Fluids

Peristaltic pumps are capable of pumping fluids with high viscosity, including thick and sticky substances such as adhesives, pastes, gels, and creams.

Hazardous & Corrosive Fluids

Peristaltic pumps offer excellent chemical resistance, making them suitable for handling hazardous and corrosive fluids, including acids, alkalis, solvents, and aggressive chemicals.

Clean Fluids

Peristaltic pumps can handle clean fluids, including water, beverages, juices, and liquid food products.

Features of SEP Peristaltic Pump Series

Long Life Hose

A hose is the core component of a peristaltic pump. Generally, there are three layers on the hose: the inner layer, middle layer and outer layer. SeFluid’s hoses have an inner layer of special rubber. The high quality inner rubber is specially for application with corrosive and abrasive fluids. For middle layer of reinforcement, the material is high quality nylon. This nylon enables the hose to withstand pressures up to 16 bars. Moreover, it has excellent fatigue resistance.

Meanwhile, for the outer layer, the material is high quality wear-resistant rubber. This type of rubber strengthens the strength of the hose. In addition, it has excellent wear resistance ability and can withstand frequent rolling and high temperatures generated by friction. Moreover, SeFluid applies high precision equipment to machine each hose to ensure that the hoses fit the pump perfectly.

No Need of Lubricant

In current market, most peristaltic pump brands use a sliding shoe as squeezing device. The contact between the squeezing device and the hose is by means of sliding friction. In order to reduce damage to the hose from the sliding friction, it is necessary to fill in the pump cavity with a large amount of lubricant. Besides, users need to replace the lubricant after extended use or when replace the hose. Replacing the lubricant is cumbersome, time-consuming and costly. Furthermore, the replaced lubricant has the potential to contaminate the environment.

Moreover, after the hose has reached its service life, it may rupture unexpectedly for special reasons. Then the lubricant may penetrate directly into the pumped fluid. Consequently, serious contamination of the fluid may occurs. For industries such as pharmaceuticals or foodstuffs, this will make very serious consequences.

Meanwhile, all SeFluid’s pumps take rollers as the squeezing device to replace sliding friction with rolling friction. Therefore, there is no need to fill the pump cavity with lubricant. In conclusion, our peristaltic pump series has features of  lower maintenance costs, easy hose replacement, short downtime and no contamination of the environment or the material.

High Performance Gearbox

The gearbox is also an important component. It determines factor for the life of a peristaltic pump. The gearbox greatly increases the torque of the central shaft by reducing the speed of the motor. It drives the pump rotor to crush the hose and transfer the material. On all SeFluid’s pumps, top brands of gearboxes are applied to offer small size, high torque, long life and quiet operation. Each gearbox is carefully regulated and tested before delivery. Our pumps are designed to work well throughout their lifetime without special or additional maintenance.
