Hidrolik pompalar hidrolik sistemlerin arkasındaki itici güçtür, silindirlere akış ve basınç sağlamak, motorlar, ve diğer bileşenler. Önde gelen üreticilerin sunduğu pek çok pompa modeliyle, selecting the right one for your application can be challenging. Variables like pump design, displacement, pressure rating, and controls all factor into the decision. In this article, we’ll look at popular pump lines from Bosch Rexroth, Parker Hannifin, and Eaton Vickers to shed light on the options.
Bosch Rexroth A6VM and A4VG Axial Piston Pumps
Bosch Rexroth is a major global player in hydraulics, producing a diverse range of pumps, vanalar, silindirler, ve diğer bileşenler. Their A6vm series 71 and A4VG lines of variable displacement axial piston pumps cover a wide range of applications with sophisticated design and precise controls.
The A6VM series utilizes a swashplate design to achieve pressure compensation, variable displacement, and fast response times. With eleven frame sizes and displacements from 1 ile 500 cc/devir, it can be tailored precisely to specific flow and pressure requirements. The unique multi-angle swashplate design reduces friction losses and increases mechanical efficiency.
For mobile applications and other demanding duties, the rexroth a4vg series 40 offers similar advanced features with several advantages. Its unique valve plate design with no kidney slots allows higher pressures, reduced noise, and greater efficiency across variable speeds. The dual-axis design keeps thrust loads balanced for long service life. Displacements from 32 ile 250 cc/rev equip it for tough jobs.
Both lines offer options for load sensing, pressure compensation, and electronic controls. This allows them to maintain precise pressures and respond quickly to system demands. For challenging hydraulic power needs, the A6VM and A4VG deliver sophisticated engineering and technology.
Parker F1 Series Fixed Displacement Pumps
While Rexroth focuses on variable pumps, Parker Hannifin provides a diverse hydraulic pump catalog including extensive fixed displacement models. Their F1 series offers an example of a rugged, high-performance fixed pump line spanning a wide range of applications.
F1 models utilize a compact radial piston design, with pressure ratings up to 5,000 psi and flows to 265 GPM depending on displacement. The forged steel rotating group and thermally-stable shaft deliver robust performance and minimal seal wear in demanding conditions. Replaceable inlet filters protect the pump.
Parker engineered the F1 line for quiet operation across operating speeds. This makes them well-suited for equipment cab installations. Options like pressure compensation, shock valves, and custom ports provide flexibility. Displacements range from 1-6 cubic inches to handle various flow requirements.
With a compact modular design, the F1 fits well into tight spaces. It can be directly coupled to engines and motors or driven remotely. For reliable, efficient hydraulic flow across operating speeds and conditions, Parker’s F1 series is an excellent choice.

Eaton Vickers V Series Vane Pumps
Moving to vane pump designs, Eaton Vickers offers the versatile V Series. These fixed displacement vane pumps provide smooth, pulse-free output across operating speeds. The double-sided vanes conform closely to the cam ring, delivering efficient flow across a wide viscosity range.
Vickers vane pumps are engineered for long service life with features like replaceable cam rings, end disks, and vanes. The rear cover can be rotated to orient ports in the best direction. Rugged cast iron construction provides durability, with pressure ratings up to 3,000 PSI.
Eleven displacements from 3-250 cc/rev equip the V series for a range of flows and applications. Compact inline and right-angle models fit well into tight spaces. Options like backflow limiters and pressure regulators allow customization for specific needs.
Choosing Your Hydraulic Pump
This overview of popular hydraulic pump lines provides a snapshot of the range of options on the market. Variable displacement pumps like Rexroth’s A6VM and A4VG series offer maximum flexibility and control. For simple robust fixed flow, Parker’s F1 radial pistons or Eaton Vickers V series vanes are great solutions.
