The Four Main Types of Hydraulic Pumps

The Four Main Types of Hydraulic PumpsIf you have a hydraulic system, you ned to understand the differences in hydraulic pumps. With the right knowledge, you can make sure all of you pumps operate correctly and give you the performance you need.

There are many different types of hydraulic pumps available, but let’s look at the four main kinds that you will need to know…

Understanding the Different Types of Hydraulic Pumps

Gear Pumps

Machines and combustion engines need the right amount of lubricant in order to operate smoothly. Depending on the machine, there could be thousands of gears that need lubricant, and a gear pump helps keep all of these components running strong. Gear pumps are used as a lubrication systems that injected fluids into gears using pressure to make sure the lubrication reaches all the nooks and crannies. Gear pumps can also be used in hydraulic power steering systems to move fluids.

Vane Pumps

Used in die-casting and injection-molding machinery, vane pumps operate with a much lower flow pulsation. In other words, they have a constant flow, which produces much less noise while helping the machinery maintain a high speed. In most cases, the operating pressure of a vane pump will not go over 175 bars, but there are vane pumps that can operate at pressures exceeding 300 bars. Available in both single-chamber and double-chamber, hydraulic vain pumps are also an important component for land and road construction machinery.

Axial Piston Pumps

These types of pumps operate in open or closed circuits, offering variable speed settings that can be set to fixed or fluctuating input speeds. They offer an immediate and jolt-free change in direction for fluids, and have a simple operation with a high turnaround. Axial pistons are extremely useful for the travel drive and working hydraulics  for mobile machines.  Axial pistons have an important components that will change depending on your needs. The pumps can have either a swash plate or a bent axis design.

Radial Piston Pumps

If you have a system that runs at high pressures, you will need to know about radial piston pumps, which are generally made to operate at pressures between 400 and 700 bars. Inside these pumps, the pistons extend in a radial direction around the drive shaft. They are generally very efficient and have a low noise level. They are often used in presses, machines that process plastics, and machine tools that clamp hydraulics. As the only type of pump that is capable of working at these high pressures, especially at continual operations, radial pumps are an essential part of many hydraulic operations.
