- This video clearly explain various types of hydraulic pumps used in industry and its Working principle.
Types of Hydraulic Pumps:
1.swash plate piston pumps
2.Radial piston pumps
3.Rotary vane pumps
4.External gear pumps
5.Internal gear pumps
6.Hand pumps
Where are hydraulic pumps used?
Hydraulic pumps are an integral component of every hydraulic transmission system. It is the hydraulic pump that is tasked with converting mechanical energy into hydraulic energy. This process is facilitated by the pump inputting a force in a way that creates a flow of the hydraulic fluid. It is the pressure within the hydraulic fluid that facilitates the transfer from mechanical energy to hydraulic.
Hydraulic pumps are most commonly found in steel mills, foundries, lifts, conveyors, injection molding machines, shear and stamping presses, mixers, forklifts, pallet jacks and more.

You missed one of the really neat things about a swashplate piston pump: the ability to change the swashplate angle can be used for automatic pressure regulation. When the outlet pressure increases, a small piston tilts the swashplate to reduce its angle. When the system is at the set max pressure, the swashplate is completely flat so no fluid is pumped. The shaft can be rotating at constant speed from e.g. an internal combustion engine.
बहुत बढ़िया से समझाया है. सारे हाइड्रोलिक पंप को यहां परोसा गया है.
I've worked on and rebuilt every one of those pump types except external gear. Have also worked with; gerotor pumps, air/mechanical/hydraulic powered diaphragm pumps, hose pumps, screw pumps, ram pumps, air-over-hydraulic/hydraulic-over-hydraulic amplifiers and scroll pumps. Along with numerous varieties of non-positive displacement pumps. Often you will find axial piston pumps (the kind with the swash plate) in an automatic compensating design. It adjusts the swash plate to maintain a constant pressure, need more oil then it makes the plate steeper, needs no oil, it drops the plate to 0, you can also find vane pumps in compensating design by adjusting the eccentric housing to change the amount of vane throw.
thank you for the animation. makes understanding very easy. i never knew that the rotary vane pump is not suitable for liquid with high viscosity.
Bravo! Well done and thanks for sharing.
Aku video menambah ilmu saya terimakasih videonya... 👍👍🙏🙏
PERFECTAMENTE CLARO....GRACIAS
Excellent illustrations.
The Ford 1953 NAA tractor first came out with vain pumps, later models came out with piston pumps. My NAA still has the original vain pump. I might have a video of the internals. Really interesting technology
It looks like my Jubilee has a piston pump. I hope it never fails because they're $900 at Steiner's and even more expensive at other places!
You said hand pumps are always a piston type, that's not true there are external gear pumps that are hand powered for transferring oils ,fuels and other liquids. I've used them a lot over the years.
True =) we had one of both types with the lever and the svivel handle , at my old job . And all garage jacks or donkraft is opperated by a handle lever . the same thing he explaines here =)
Looks like the video is stolen so kinda moot
A "hand pump" is a specific type of hydraulic pump. What you are describing is still an external gear pump, regardless of whether it powered by a motor or hand crank.
@@DefensorMilitas a "hand" pump is just a method to drive it. Doesn't really matter, the hand isn't pumping. I think most here understand that the pump; being a gear, vane, piston, diaphragm, etc. is the actual pump. How it is arranged (opposed, radial, excentric, etc.) and or driven is a different matter.
That's right
I worked in pumps manufacturer, most of these are gear pump for high viscosity fluid like oil or fuel.
Great animation tho, but i expect to see pumps like multistage pump, single suction/double suction pump, vertical turbine, or any of that mostly used in industrial/buildings.
So gear pumps are very common?
Very very useful information
I want to send you thousands of like
Nice video presentation, very easy to understand thank you🙏
Pity he didn't say what applications these pumps are used in.
Use them however you want.
What pumps can be backdriven... What pumps convert hydraulic pressure to mechanical power?
We use the radial pump in 80m 3MW wind turbines to pitch blades. 200bar working pressure
Very good video. And no background music - I love it!
But hand pumps are not always pistons. And you forgot the ram pump (Widder) which needs no motor.
Thanks for video....
I got help watching your video......
Vídeo incrível!
This video is good informative on gear pumps
Thanks alot for your explanations.
Really informative.. Thanks 🌹
I worked on a swash plate variable volume pump, constant pressure but volume could be varied by tilt of swash plate via pilot control providing variable speed at constant pressure to hydraulic motors.
The radial and the swash plate seem very similar to each other.
That's the type I was hoping they'd go into in detail when I clicked on this video
Swash
@@brodriguez11000 Yes and No. You can vary the displacement (volume per revolution) of the axial piston design, but not on the radial piston type. Both are similar in that it's a reciprocating piston that provides the flow aspect.
Dear,which gear is best perfomance in exavator operation ?
Hi,
What software tools were used to make this video?
Thank you!
What program did you draw on?😊
The rotary vane pump doesn't make sense to me. Well, it makes sense, but I see a problem. I was taught that water is incompressible. This pump is trying to force it into smaller and smaller volumes, which you just cannot do to water.
Is water not "low viscosity"? Is this pump only meant for compressible fluids (like most gasses)? Or is there something else I'm missing?
I suppose they could make the intake and output cover almost all of the circle, allowing the water to go in/out of the pipe and not break physics
great video
All of these remind me of components I've worked on in a car XD except rotary vein pumps.
The last PAS pump I had to bits was a rotary vane type.
To be fair I didn't put it back together again..
Great explanation
I used one of these well .. Im pretty sure it works like this. Was used for lifting car engines but we are useing it for rocks. Super heavy stuff id watch out for hate it when my boss scoots between the load and me. Im just a safty sally because if seen some bad accedents. I love this though ! You can move super heavy stuff without useing gas engine just your arms and that jack. Its pretty cool though I hope I 100 percent understand this how it works its just to cool.
Very GOOD 😀
Great explanation sir
Thanks and welcome
by external gear pomp :
does size of inlet and outlet ports matter? one is clearly bigger from another...
Different sizes to force placement in only one direction.
You never want a restriction on the supply side.
What is the reason no pressure build in positive displacement pump ?
A Pump does nothing more than generate FLOW. Load or resistance to flow is what creates (back)pressure. So if you have a route back to tank without resistance than can handle all of the pump flow, you will never generate pressure.
Missing the air driven Sandpiper pump, the hose pump, sinus pump, screw pumps (Bornemann), lobe pumps.
All positive displacement pumps. So some animation to do.
But, what is now in the video looks very well 👍
Diaphragm pumps - but why not include non-positive displacement pumps ?
Not to mention the ion getter pump. Man this is a eight minute video.
Which one is the pump for hydraulic elevators?
អគុណបងthank
Which type is the quietest?
Can anyone suggest what type of pump can operate , medium thick liquid + small particals of sand.
អគុណបង
sir, I need a parts book of hydralic press cutting machine .can I have pdf file ?
What about vibration pomp?
I never saw a swash plate piston pump that used springs, the pistons are attached to the plate.
Vane pumps are used at lower volume but 2500 to 2800 psi in some applications on trash trucks.
On a Cat 651B scraper they used a vane pump at 3500psi if i remember right, it's been a looong time.
Best alternative to the internal gear pump on engines for engine oil? Would a vari displacement vane pump be more efficient, keeping the pressure at required 8bar but not pushing exes oil over the pressure relief valve?
@@LukaS-iy1gs I believe the 'excess' is the bit that flows through the oil filter.
Only come across 1 vane pump - high volume air compressor.Correction - I think marine engine water pumps are of a flexible vane type and, as it happens, I've similar that can be attached to an electric drill.
@@LukaS-iy1gs cost, complexity and probably size would be 3 reasons to stay with a gear pump
I have seen spring loaded swash plate pistons in Hydrostatic drive units on lawn and garden tractors. Look up a Tuff Torq K-46 it has spring loaded pistons
Thanks
superb animations. makes the learning experience a fun.
One of the external gear pumps' biggest disadvantages is missing: the liquid flow is uneven, pulsating, so they are not appropriate where even and continous liquid supply is required.
In what applications this is issue? In hydraulic motors?
thats why pressure regulators were invented. takes the hammer out of the fluid.
@@_AndromedaGalaxy_ Not even close. Pressure regulators are similar in scope but light years different in performance than spike clipping relief valves.
Thank you indeed. It make my head so clear.
which type is best for liquids that are contaminated with particulates? (i.e. muddy water)
the discflo pump, like a tesla to look at is available. Can even pump live fish they claim!
in which category the swash plate pump exists
Thank you more
Nice video
а спиральных, винтовых, центробежных, шнековых типа не существуе?
tq sir
Very good vedio .....
Immpresive
❤️
Which of these used in tractors
excellent video💕💕💕💕💕💕💕💕
3:05 also used in engine lubrication, albiet with different teeth profile. Trochoid pumps they're often called. More modern design but they've been circulating engine oil for decades in their own right; my 36 year old Ford truck uses a trochoid pump for oiling itself.
peristaltic pump?
How about screw pump ?i have it sir..
Problem with external gear pump design is a high chance for cavitation.
and high chance of contamination in your system too
@@phen0m54 Contamination with what?
Was a maintenance electrician for 50 years and was amazed how much lower hydraulic pumps produce. Only down side appears that every hydraulic hose leaks. Had a company come in and spend over a week during yearly shutdown to replace every hydraulic hose on a large machine. Laughed in their face when prima donnas said " you will never have a leaking hose" . Several started leaking first week. Best one that I saw was in a large slaughter house that used a hydraulic piston to split cow & steer heads in halve. Would split 6 by 6" lumber in it.
Please make the bell ringing louder
That was excellent video, Great help understanding
2:03 very common engine oil pump design, especially in older engines.
What about turbine and impeller pumps
No mono pump?
How much price of hydraulic master cylinder
None of the centrifugal pumps are mentioned and missing info given for the ones explained. There are API pumps around
This is about hydraulic pumps and Centrifugal pumps are non positive displacement pumps and therefore not used in hydraulics.
somebody please explain: why does the hydraulic pump multiply the force created by thepower source, rather than be a decimal of it?
It doesn't multiply force..... it simply convert mechanical energy (or electrical energy into mechanical energy via electric motor) into hydraulic energy. The hydraulic energy is simply liquid flow at a given backpressure (resistance to flow).
Missed shuttle black pump?
So what hydraulic pumps go in a excavator?
The tilted swash plate piston pump is used in many excavators. I guess the radial one could be good for them too. They seem to produce constant pressure, and high power.
3:12 Moje gratulacje. Wymyśliłeś okrągły wirnik, którego oś obrotu nie znajduje się w jego środku!!!
no
w czym problem
Search by write : load signal hydraulic pum piston
Missed out screw pump
Centrifugal pump
Hey, did you straight up "stole" this video from another channel? Or something else is happening here?
The internal gear pump has a banana in it?
You forgot the Belier pump!
In reverse the first gears
Sarang Patel (TY ME)
very goo
Which one work better ?
First
Depends on application. A piston pump is real common because you can vary flow rate an direction with the pump. An they can "idle" with no flow an minimal hp drag.

Hello
I see
He left out diaphragm pumps
He left out most pumps
Mboh
Good video. But horrible robotic narration.
Mr. robot voice is talking to you please pay attention
this video is directly stolen from a different youtube channel
السي التطواني أنا لا أريد قتل أحد هم يأخذون بعض الكلام في حالة الغضب حجة علي
Yeah, that voice over is gonna be a no for me dog.
Pumps only rotate counterclockwise. Half of what you said is a lie.
Another type of pump is the steam injector used on locomotives. These have no moving parts but can inject water into a pressurised boiler. See en.wikipedia.org/wiki/Injector
