How much pressure can a peristaltic pump generate?
Typically, peristaltic tubing pumps offer flow rates as low as 0.0007 mL/min to 45 litres/min and are able to generate pressures up to 8.6 bar (125 psi).
What is the maximum viscosity for a peristaltic pump?
Peristaltic pump technology can pump high viscosity products up to 30,000 cps. This range of pumps allows dry running without deterioration.
How many types of peristaltic pumps are there?
two types
There are two types of peristaltic pumps: hose pumps and tube pumps. Tube pumps are perfect for lower flow rates, are fully programmable, with the option of multiple heads, while hose pumps are perfect for pumping highly solid content.
Which tube is used in peristaltic pump?
Vinyl tubing cannot be autoclaved and should not be exposed to temperatures above 80°C. Silicone is the most commonly used peristaltic pump tubing. It has the longest service life and good chemical compatibility for aqueous and many organic solvents and is often used on the Sulfate chemistry which contains alcohol.
Can a peristaltic pump pump air?
As a precision peristaltic pump, can a peristaltic pump pump air? The answer is yes. Through the working principle of the peristaltic air pump, we can know that the peristaltic tube pump transfers liquid through rollers squeezing the hose.
How do you calculate the flow rate of a peristaltic pump?
The first,The flow rate Q is proportional to the speed n. The higher the speed, the greater the flow rate. For example, when the peristaltic pump is 1rpm, the flow rate Q= 1ml/min, and it can be deduced that when the peristaltic pump is 10rpm, the flow rate Q= 10ml/min.
How deep can a peristaltic pump work?
The mechanical peristaltic operation uses rotating rollers to depress the silicone tubing, creating a vacuum, which displaces any fluid or gas in the chosen direction. It is effective to depths up to the suction lift limit, which varies with elevation, and can be as much as 33 ft. or 10 m at sea level.
Which pump is used for high viscous fluid?
The EDDY Pump makes a great choice for pumping highly viscous material. The EDDY Pump’s geometric rotor acts as a mixer on thixotropic materials and provides a shear thinning effect enabling the pump to move high viscosity liquids much more efficiently than other pumps.
What is the maximum viscosity for a centrifugal pump?
Maximum Viscosity for a Centrifugal Pump
Several references limit centrifugal pumps to a maximum of 3,000 centistokes. (Note that this limit is also published as 3,300 centistokes.)
What motor is used in peristaltic pump?
Typical motor speeds for peristaltic pumps range between 0-400 revolutions per minute. Usually, DC and BLDC motors are used together with a gearbox to set speed depending on the flow need.
Can a peristaltic pump run dry?
Peristaltic pumps do not require pumped fluid to be continually present, and pumps can run dry without costly downtime or repairs. The recovery of the hose or tube creates a powerful self-priming action and allows the pumps to move liquids containing entrapped air or that can offgas.
How do you calculate flow rate from RPM?
FLOW RATE – Centrifugal Pump Sizing Calculation: RPM – YouTube
How do I calculate flow rate?
Rate is the flow rate or speed of the water, using the unit “meters per second. “ For example: The object travels a 5 meter length of stream in 8 seconds. Divide 5 (length traveled) by 8 (time it took to travel the distance) for an answer of .
How long do peristaltic pumps last?
Life depends on the hose in speed, outlet pressure, hose material and chemical compatibility, Shen Chen standard peristaltic pump hose life is about 200-300 hours (600rpm, 3 wheel), the lower the speed, longer hose.
Which type of pump is most efficient?
The most efficient type of pump is a rotary vane pump. This type of pump has a maximum efficiency when the fluid is moving in a circle. Other types of pumps have different efficiencies when pumping different fluids.
Does viscosity affect flow rate?
The short answer is; as viscosity increases, flow rates decrease.
How is viscosity calculated?
There are several formulas and equations to calculate viscosity, the most common of which is Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.
How do I choose a pump size?
In pump sizing, two factors are needed to select a pump: flow and pressure. Flow is generally measured in gallons per minute (gpm). The max instantaneous flow that will be entering the pump’s basin needs to be determined so that a pump can be selected to efficiently maintain the system.
What is normal flow rate?
Normal flow rate is 1 atmosphere (101.3 kPa) or 14.696 psia at 32 0F (0 0C). Actual flow rate is the actual volume of fluid that passes a given point based on given pressure and temperature of the process.
What is m3 per hour?
m3/hr means cubic metre of gas per hour; and. Sample 1.
What are the 2 main classification of pumps?
Main Types of Pumps: Centrifugal and Positive Displacement.
What does API 610 mean?
API 610 is the API standard relating specifically to centrifugal pumps and centrifugal pumping systems. It provides design criteria for the design of the actual centrifugal pump, as well as how the centrifugal pump is to be tested, and what type of base it is to be mounted on.
What is unit of viscosity?
The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.
What are pump specifications?
Specifications. Pumps are commonly rated by horsepower, volumetric flow rate, outlet pressure in metres (or feet) of head, inlet suction in suction feet (or metres) of head. The head can be simplified as the number of feet or metres the pump can raise or lower a column of water at atmospheric pressure.
