Hydraulic Gear Pump
In the 1960s the aerospace industry was growing by leaps and bounds. During that time, Eaton began making
Dump truck parts lifting gear pumps GPG55 Hydraulic pump models for both that industry and other manufacturers. These days, they deliver all their gears and pumps to customers all over the world for mobile and industrial applications.
Any Eaton hydraulic gear pump or other product is cutting edge. Eaton has spent years coming up with designs and ways to manufacture gears. Every one of their customers want each to buy a product that will work better, quieter and longer than the one before. On top of that, each product must have more features and options. To satisfy this need, Eaton has a large variety of gear pumps so that each customer's needs are met. They incorporate as many features right into the pumps to maximize function and minimize size requirements. Whatever your application, there is an Eaton gear pump for it.
Every Eaton hydraulic gear pump has a floating bushing, pressure balanced design. The body is extruded of an aluminum alloy that has a high resistance. the end cover and flange are both made out of cast iron. You have a huge choice of flanges, shafts and ports, so that you can meet with the standards for your county and industry. It also means that you can get a pump that fits in exactly with what you need. There are plenty of benefits to getting an Eaton pump. They are low noise and have a low pressure ripple. They can be used for just about anything in any industry. They are small enough to fit in almost any space, but big enough to do anything you want them to do. The pumps are also pre-engineered so you don't have to deal with it. With their long experience, Eaton has a pump that will work for you.

Know About the Two Basic Types of Fuel Pumps
A fuel pump is an essential component in an automobile's fuel delivery system. In most of the vehicles we find engine located at the front-end of the vehicle and the fuel tank at the other end. The main function of fuel pump is to draw the fuel from the storage tank and force it to the engine.
Though some old designs do not require fuel pump, for
VQ Series Pump Core Suppliers many of the latest non-gravity based engines it is an essential component and is often termed as 'the heart of the vehicle'. In this article, we will discuss about the two basic types and the advantages of one over the other.
Types of fuel pumps
• Mechanical: There are two types of mechanical pumps - old style mechanical pumps and new style GDI pumps.
o Old style mechanical: They can be found in few old model engines that have carburetors. The pump draws fuel from the tank and pushes it to the carburetor when the engine is running. Their output pressure is quite low - 4 to 10 psi. These low pressure pumps are often mounted on the top of the engine.
o New style high pressure GDI pumps - The advent of Gasoline Direct Injection (GDI) systems which can deliver fuel at very high pressures has given rise to the high pressure fuel pumps driven by camshaft. These high pressure pumps can generate fuel pressure up to 2,000 psi and higher, which help the GDI engines to achieve improved fuel economy with high power output and reduced emissions.
• Electrical: Electrical fuel pumps are used in fuel injection systems (introduced prior to GDI system) to pump the fuel from the fuel tank to the injectors. They typically deliver fuel at 30-85 psi to the fuel injector, which then opens and sprays the pressurized fuel into the engine. Unlike old mechanical, electrical fuel pump is typically located in or near the fuel tank.
Today, a variety of electrical fuel pumps meant for various applications are available in the market, such as:
o Roller vane pumps: They are positive displacement pumps that consist of vanes/blades to push the gas through the pump. They are often used in large trucks and also in diesel powered cars.
o Turbine pumps: They are not positive-displacement pumps. They have an impeller ring attached to the motor, which has blades to push the fuel through the pump. This pump runs smoothly and quietly and is mostly used in the latest vehicles.
o Gerotor pump: This is another positive displacement pump which uses an offset rotor to deliver the fuel through the pump. They are used in passenger vehicles.
o Solenoid pumps: They use a piston which is activated by an electromagnetic coil to generate pressure and thus help the fuel flow. They have many applications and are considered as universal type of electric fuel pumps.
o Peripheral pumps: They have impellers which pull and push the fuel. This is the standard type of pump used in many vehicles. Though they work much quieter, they produce limited pressure.
o Brushless pumps: These pumps have a fuel inlet and outlet between which a fuel mechanism is positioned with an armature to pump the fuel under pressure from the inlet to the outlet. Brushless pumps are generally used in diesel engines.
• Advantages of electric over mechanical fuel pumps
o Smaller and lighter: Compared to the old style low pressure mechanical fuel pumps, electrical ones are small in size and light in weight. This compact size allows them to easily accommodate inside the fuel tank. Moreover, usage of small devices reduces the electrical load and thus, controls the fuel consumption. However, electrical pumps are bit expensive.
o Ability to deliver fuel at higher pressures: Old styled mechanical pumps deliver pressure of only 4 - 10 psi, electric pumps can deliver gasoline at pressures typically between 30 - 85 psi. Fuel injection system requires the gasoline to be delivered at high pressures. However, new style high pressure mechanical pumps used in GDI systems can deliver greater pressures as high as 2,000-3,000 psi.
o Improved safety: Fuel injection systems have a special device called Electronic Control Unit (ECU) which controls power to the fuel pump. It is specially programmed to shut off the fuel pump if it detects low or zero pressure. This safety feature avoids the risk of fire in engine compartment in case of collisions or terminal failures. As mechanical fuel pumps lack this feature, electrical pumps are considered to be safer.
o Highly durable: The presence of pump inside the tank allows it to get cooled by the flow of the gasoline. This prevents overheating of the electric pump, which is an issue with mechanical pumps (as they are mounted on the top of the engine), and thus increases the life of the electric pump.
o Alleviating vapor lock issues: If the vehicle is left unused for some time, the liquid fuel inside the tank changes to gaseous state and thus disrupts the operation of fuel pump causing loss of feed pressure to the carburetor. Vapor locks are quite common in old fuel systems with low pressure mechanical pumps. But in case of electric pumps, as the pump is in the interior of the tank and runs cooler, the pump pressurizes the fuel lines and prevents vapor locks.
With the increased use of aftermarket fuel pumps many companies have started manufacturing various varieties. Purchasing them from a reputed and experienced manufacturer is always a good idea.

Do you know someone that has just been diagnosed with diabetes
Do you know someone that has just been diagnosed with diabetes? Here's the DSG series gear oil pumps experiences of one teenager and how they learned to cope with being diabetic, using an insulin pump and so much more - that teenager is me!
You'd have thought that having had diabetes for almost 8 years I would have gotten to a complete and utter control, but the fact is that I haven't! I have found it really very difficult to control my sugar levels, and even harder over the last year, my first year of university.
I was diagnosed with diabetes at age 11, two weeks into my first year of secondary school. I was put onto 2 injections a day, which seemed to suit me fine at the time. (Of course at 11 there weren't really any hormones and there was a strict routine!) But after two years of 2 injections and increasingly poor health my mother decided that we needed to find a more suitable option for me. She found out about Minimed via the internet, and after some serious research and trials with our local health authorities I was given an insulin pump. I was used to it after a week, and seemed to know exactly what to do.
Over the next few years I would experience some difficult doctors advice, one of which told me that I would become ill if I didn't sort out my sugar levels. This is because of one thing that we would never have counted upon - with the freedom that is given by an insulin pump, the less you feel restricted, the less you feel like you have diabetes, and therefore the lazier you get. It seemed to be a slippery slope down (or I should say up as my blood sugar levels were rising!) into poorer health. The thing is the worse your levels become the harder it is to get them back to normal again, because your body gets used to all the extra sugar. I would love to blame lack of proper support from my local medical authorities, but really it all comes down to how much effort you put in to make you feel 100%.
Anyway, so I am currently at the stage of working out exactly what it is that I need to do in my life currently to make things work for me, but that is an entirely different, and I need to go and check my blood sugar level.
Remember, you can live with diabetes and enjoy your life.
