An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder block. It can be used as a stand-alone pump, a hydraulic motor or an automotive air conditioning compressor.
A radial piston pump is a form of hydraulic pump. The working pistons extend in a radial direction symmetrically around the drive shaft, in contrast to the axial piston pump.

What is difference between internal gear pump and extenal gear pumps?
one has external teeth the other has internal teeth
What are the disadvantages of piston pumps?
Piston pumps can be more complex and expensive to manufacture and maintain compared to other pump types, such as diaphragm or centrifugal pumps. They are also prone to issues like wear and tear on seals and pistons, which can lead to leaks and reduced efficiency over time. Additionally, piston pumps can generate a pulsating flow, which may require additional components, such as dampeners, to ensure smooth operation in certain applications. Lastly, they tend to have lower flow rates and can be less efficient at handling viscous fluids compared to some alternatives.
How oil pumps work?
Oil field pushrod pumps ("donkey pumps") are reciprocating piston pumps. The long rod attached to the nodding head of the donkey pump extends down the well pipe. At the bottom of the pipe, an attached piston is moved up and down by the motion of the rod. The piston is fitted with a one-way valve, and the bottom of the pipe is also fitted with a one-way valve. As the piston descends, its valve (the "travelling valve") opens, allowing oil to pass through into the space above the piston. At the same time, the valve at the bottom of the well pipe (the "standing valve") closes, so that no oil is pushed out the bottom of the pipe. When the piston begins to rise, the travelling valve closes so that the oil now above it is lifted up the well pipe...while the standing valve now opens, allowing more oil from underground to be sucked into the bottom of the well pipe. The process repeats, with each upward stroke of the pump delivering around one to ten gallons of liquid...oil, possibly with some water mixed in.
Is it possible to run a piston using either steam or an electric motor?
You can run a piston with any sort of power, steam, hydro, electric motor. Electric motors are often used to move a piston in pumps, but the rotary type pump is much more efficient. Today steam is normally used to move a turbine, not a piston. Most pistons are used in internal combustion machines and are used to capture to power of the explosion.
Comparison between centrifugal pump and gear pump?
both gear pump and reciprocating pumps are positive displacement pumps.but the different is gear pump rotary type.reciprocating pump moves liner motion.the piston moves up and down in straight line.
Types of positive displacement pump?
gear pump, crescent gear pump, axial-piston pump, radial-piston pump, linear-piston pump, & vane pump Also, fuel injection pumps such as linear piston pumps and rotary piston pumps.
What is the difference in working between axial flow pumps and mixed flow pumps?
In axial flow pumps, fluid enters and exits along the same direction parallel to the rotating shaft giving high flow rates and low head. In radial flow pumps, fluid enters and leaves perpendicular to the rotating shaft giving high head and low flow rates. Thus, in mixed we have combined of both axial and radial.i.e.Liquid will go behind the impeller at certain angle between 0-90degrees normally below 45degree.Mixed flow replace axial when we require head not provided by the axial pump as we have to lift water from a water a lower level and then discharge it. physically,mixed flow can be identified by bellmouth(diverging converging shape) which shows its between axial and radial.

Is a piston pump hydraulic or pneumatic?
both, if it pumps liquid then it's hydraulic, if it pumps gas it is pneumatic
What are the advantages and disadvantages of axial piston pump?
Axial piston pumps offer high efficiency and compact design, making them suitable for applications requiring precise flow control and high pressure. They are capable of variable displacement, allowing for adaptable performance based on system demands. However, disadvantages include potential sensitivity to contamination, which can lead to wear, and typically higher manufacturing and maintenance costs compared to other pump types. Additionally, they can be more complex to install and operate.

How many types of pump use in industries?
In industries, there are various types of pumps employed for different applications. These include centrifugal pumps, positive displacement pumps, diaphragm pumps, peristaltic pumps, and gear pumps, among others. When it comes to precision infusion tasks, such as in medical or laboratory settings, IPS Syringe Pumps are often favored for their accuracy, reliability, and ease of use. These pumps excel in delivering controlled and consistent flow rates, making them a popular choice for a wide range of industrial applications.
What is the difference between stilettos heels and pumps?
The heels are stilleto-like (skinny) on one & not the other.
What is the difference between a amateur and professional runner?
There is not significant difference between rest cardiac output but during the load amateur heart pumps 18-24 l/min, professional heart pumps 32-38l/min.
Why pumps not used to pump the gases?
That's not strictly true. Gases are pumped by using pumps such as piston pumps and vane pumps. A garage compressor has the air pumped into the tank by a piston pump. Even a bicycle pump is often used. however, when gases are "pumped" it by definition becomes a compressor. pumps move basically un-compressible fluids. low pressure gas transfer is termed a blower, while higher pressure usage requires a compressor.
