Description
Technical Parameters
Peristalic pump, also known as peristaltic pump pressure control, is a fluid transmission equipment widely used in scientific research, medical, industrial and other fields. Its working principle and structural characteristics give it unique advantages and broad application prospects in specific fields. As an important fluid transport device, it has broad application prospects in various fields such as food processing, pharmaceuticals, environmental protection, chemical engineering, printing and coating. By adjusting the speed, selecting appropriate pum head models, and hose materials, precise flow control and stable pressure output can be achieved. However, during use, there are also challenges such as hose wear and replacement, fluid characteristic adaptability, and maintenance and upkeep.The pressure control method of peristaltic pump has two kinds of manual adjustment and automatic adjustment.
Specifications
Working principle
The core of a peristaltic pump pressure control is to use one or more rotating rollers or cams to compress the flexible hose installed inside the pump casing. When the roller rotates and squeezes the hose, the cross-sectional area of the squeezed part of the hose decreases, forcing the fluid inside the hose to move forward. After the roller is released, the hose returns to its original state, forming a negative pressure area that attracts more fluid into the rear of the hose. As the roller continues to rotate, this squeeze release cycle repeats, achieving continuous and precise fluid transport.
The main components of a peristalic pum include:
Efficiency leap Precision and stability
Drive mechanism: Provides a source of power, commonly including electric motors, pneumatic motors, or manual crankshafts.
Roller assembly: This is the core component of a peristalic pump, typically consisting of two or more rollers (sometimes camshafts) that alternately squeeze the hose. The rotation of the roller creates a closed fluid chamber inside the hose, pushing the liquid forward.
Hose/tubing: The peristalic pum uses a specially designed elastic hose as a fluid channel. The material of the hose depends on the properties of the liquid being transported, such as chemical compatibility and temperature range. It is a consumable and needs to be replaced regularly.
Efficiency leap Precision and stability
Pump head/pump casing: Fix the roller assembly and hose to provide support for the hose and keep it in the correct position. The pum head design ensures that the hose is uniformly and appropriately compressed, while also facilitating the installation and replacement of the hose.
Inlet/outlet connector: Connect the two ends of the hose, corresponding to the inlet and outlet of the liquid respectively, to ensure smooth flow of liquid in and out.
Control system: In an electric peristalic pump, the control system is responsible for adjusting the motor speed, monitoring the working status of the pump (such as flow rate and speed), and may include a digital display interface that allows users to set and adjust pum parameters.
The working principle of peristalic pumps is simple and efficient, which gives them unique advantages in the field of fluid transmission.
Advantages and Challenges

advantage
Pollution free transmission:
When a peristalic pump transfers fluid, only the hose comes into contact with the fluid, so replacing the hose can be applied to different media, avoiding the problem of cross contamination. This characteristic gives peristalic pumps a unique advantage in industries such as food processing and pharmaceuticals that require maintaining fluid purity.
High precision flow control:
By controlling the roller speed or stepper motor, peristalic pumps can achieve precise flow control. This characteristic makes peristalic pumps have broad application prospects in situations that require precise measurement, such as liquid ratio in pharmaceutical processes and reactant feeding in chemical processes.
Low shear force:
Due to the almost smooth movement of fluid within the hose, peristalic pumps have unique advantages in conveying liquids with high shear sensitivity. For example, in the pharmaceutical process, solutions containing cells need to avoid excessive shear forces, and peristalic pumps can meet this requirement.
Bidirectional conveying capability:
Peristalic pumps have the ability to deliver media in both directions simultaneously. This feature improves work efficiency and gives peristalic pumps a unique advantage in certain situations that require bidirectional transmission.
Challenge
(1) Wear and replacement of hoses
As the main consumable of peristaltic pump pressure control, hoses need to be regularly inspected and replaced. Hose wear can lead to fluid leakage and pum head wear, thereby affecting the service life and performance of peristaltc pumps. Therefore, how to extend the service life of the hose and reduce the frequency of replacement is a challenge faced by peristalic pumps.
(2) Fluid characteristic adaptability
Different fluids have different viscosity and flowability characteristics, which can affect the flow behavior and pressure distribution of fluids inside hoses. Therefore, how to choose the appropriate pum head model, hose material, and speed parameters based on fluid characteristics to achieve stable delivery performance and precise flow control is another challenge faced by peristalic pumps.
(3) Maintenance and upkeep
Regular inspection and maintenance of peristalic pumps are key to maintaining their stable operation and extending their service life. However, in practical applications, due to complex working environments and uneven skill levels of operators, the maintenance and upkeep of peristalic pumps are often difficult to receive sufficient attention and implementation. Therefore, how to strengthen the maintenance and upkeep of peristalic pumps to ensure their long-term stable operation is an important challenge facing peristalic pumps.
Practical application cases
In order to better understand the performance of peristalic pumps in practical applications, the following are several typical application cases:
Case 1: Cell culture in the pharmaceutical industry
In the pharmaceutical industry, cell culture is an important step. Due to the high sensitivity of cells to shear forces, it is necessary to choose a fluid transport device that can deliver at low shear rates. Peristalic pumps, with their low shear force characteristics, have become an ideal choice in cell culture processes. By precisely controlling the speed and selecting the appropriate hose material, the peristalic pump can stably deliver solutions containing cells, ensuring that the cells are not damaged during the delivery process.
Case 2: Sewage treatment in the field of environmental protection
In the field of environmental protection, sewage treatment is an important application direction. Peristalic pumps are capable of treating wastewater containing particulate matter and high concentration sludge, while also withstanding the corrosion of corrosive liquids. In the process of sewage treatment, peristalic pumps are used to transport sewage and add chemical agents. By precisely controlling the flow rate and pressure, peristalic pumps can ensure that chemical agents are added to wastewater at predetermined ratios and speeds, thereby achieving effective wastewater treatment effects.
Case 3: Sauce filling in food processing
In the food processing industry, sauce filling is a common task. Due to the high viscosity and fluidity differences of sauces, it is necessary to choose a fluid transport equipment that can adapt to different fluid characteristics. Peristalic pumps, with their strong adaptability, ease of cleaning and maintenance, have become an ideal choice for sauce filling processes. By selecting the appropriate pump head model and hose material, the peristalic pump can stably deliver sauce and ensure that the filling accuracy and hygiene standards meet the requirements.
