Did you know that the first pump that was invented was in 2000 BC by the Egyptians? you might not realize that there are quite a few unexpected uses nowadays for liquid pumps. Keep reading to learn about some of the applications where you might see a liquid pump.
1. Syringe Pump
Some pumps are capable of very high precision and they use a lead screw that is driven by a step motor or servo motor. The higher the motor’s positioning resolution is then the finer the dispensing resolution is. This is why syringe or piston pumps have a wide application when it comes to handling robotics, drug infusion, chromatography, chemical analysis, just to name a few.
A single-piston pump has a fixed displacement where the liquid is able to be drawn in or ejected. Continuous flow is another possibility where the piston pumps can still be used but two or more pistons have to be arranged in order to have one drawing liquid in and another piston dispensing the liquid.
2. Diaphragm Pump
These types of pumps have been used in artificial hearts because they have a simple spinning motor that can generate a reciprocating motion. External air pressure causes the diaphragm to move in and out and pump the blood for a patient.
A diaphragm pump is able to deliver a certain amount of measured liquid. The diaphragm cavity can be arranged to be separate from the drive motor link meaning that a brand new hygienic diaphragm can be swapped out for every patient.
3. Air Pump
Another application of a liquid pump is inside a vacuum with an air pump. It is able to create either negative pressure or positive pressure and it is connected to the working fluid tube. The sensors measure the pressure that the pump gives and determines how much liquid to transfer.
The bonus about air pumps is that they are very cost-effective and they come in many different shapes and sizes.
Powering With Motors
As you can see there are different applications where liquid pumps can be used in the world. Thanks to technology these pumps can also be powered with electric motors such as a Gast air motor.
The pro of using a motor is that the power and the speed can be controlled in order to adjust the pressure and the airflow. The motors can easily be reversed and they can be stalled to keep them from burning out.
Motors can also operate in challenging environments such as hot weather, dirty and dusty environments, etc. This gives you peace of mind that your liquid pump can still function under otherwise potentially hazardous conditions.
