How to distinguish between different sizes of peristaltic pumps tubing?
Peristaltic pumps are marked in two ways. One type uses “a*b” to indicate the inner diameter of the pump tubing, where “a” represents the inner diameter and “b” represents the wall thickness. For example, a 3*1 tubing indicates an inner diameter of 3mm, a wall thickness of 1mm, and an outer diameter of 5mm. Tubings […]
What is the difference between the inlet and outlet of a peristaltic pump?
Like many pumps, peristaltic pumps also have inlets and outlets, but there are significant differences between them. 1. Pressure Difference: The pressure at the inlet is actually suction, generated by the rebound of the peristaltic pump tubing. This pressure is generally close to the wall thickness of the tubing; for example, the pressure of a […]
What are the differences between peristaltic pumps and diaphragm pumps?
Peristaltic pumps and diaphragm pumps are two common types of positive displacement pumps. Their main differences lie in their working principles, structures, performance characteristics, and application scenarios. 1. Working Principle: Peristaltic pumps propel liquid media by squeezing the space between two rollers in a flexible tube, while diaphragm pumps utilize the reciprocating motion of a […]
How long is the life of a peristaltic pump?
Generally, the pump body of a peristaltic pump does not experience wear and tear. Therefore, the life of a peristaltic pump mainly refers to the life of the motor and the pump tubing. 1. Motor Life: Different types of motors have different lifespans. Motor lifespan is expressed in hours, referring to the cumulative time of […]
How to understand the flow rate of a peristaltic pump?
The flow rate of a peristaltic pump is measured in ml/min. It’s generally described as a range, such as 0-10 ml/min (or a-b). The actual flow rate is a number and is proportional to the pump’s rotational speed. The formula is: Rotational speed * Flow rate per revolution = Flow rate. 1. Rotational speed: The […]
What are some commonly used peristaltic pump tubing options?
Common peristaltic pump tubing options include silicone tubing, Pharmed BPT tubing, A-60-G tubing, A-60-F tubing, Viton tubing, and Chemical tubing. 1.Silicone tubing, also known as platinum-cured silicone tubing, is a sanitary tubing manufactured using a platinum curing process. It features high temperature resistance (-60°C to 200°C) and low exudation, and is widely used in the […]
How to determine if a liquid medium can be transported by a peristaltic pump?
To determine if a peristaltic pump can transport a liquid medium, you can consider four aspects: viscosity, temperature, pressure, corrosiveness, and chemical state: 1) Liquid Viscosity: Viscosity affects the ease of transport by a peristaltic pump. We generally use absolute viscosity to indicate the viscosity of a liquid medium. Common liquid media viscosities are as […]
What industries can peristaltic pumps be used in?
Peristaltic pumps can be used in most industries that require liquid transfer. Some notable industries include:
How to install an OEM peristaltic pump?
There are two main ways to install an OEM peristaltic pump: 1. Installing through the mounting holes on the peristaltic pump. In this case, a hole of the same size as the motor needs to be pre-drilled at the installation location, along with matching screw holes around the motor. This method is also known as […]
How to choose the peristaltic pump flow rate?
Many factors influence the flow rate of a peristaltic pump, primarily the following:
