FRR090 pump

The FRR090 pump is a hydraulic piston pump from Danfoss' Sauer brand. Here are some of the features and relevant information about it:

1. Basic Features:

Compact design and high power density: The compact design allows for high power output in a small space, which is very advantageous for the installation of space-constrained machinery.

Variable control function: As a variable pump, it can flexibly change the displacement according to the actual working requirements, so as to achieve accurate control of the output flow and pressure, meet the power demand under different working conditions, and improve the efficiency and energy saving of the system.

High-quality plunger structure: The internal axial plunger and shoe structure arranged in parallel adopts the pump displacement to change the piston stroke by the inclined swash plate. This design allows the pump to run more smoothly and can withstand high working pressures, with high reliability and durability.

2. Applications:

Construction machinery: widely used in excavators, loaders, pavers, road rollers and other construction machinery, to provide power support for the hydraulic system of these equipment, to achieve precise control of various actions, such as excavation, loading, paving, compaction, etc.

Agricultural machinery: It is also used in agricultural machinery such as harvesters, seeders, tractors and other equipment, which are used to drive the walking, steering, harvesting, sowing and other actions of machinery to adapt to the complex operating environment in agricultural production.

Mining machinery: It can be used for rock drills, crushers, conveyors, etc. in mining equipment to provide power for the hydraulic system of these equipment and ensure the efficient operation of mining operations.

3. Technical parameters: The specific technical parameters of different models of FRR090 pumps will be different, but they generally have a higher working pressure range, such as tens of megapascals or even higher; There are also a variety of displacements to meet different power requirements.

There are some differences between the Danfoss FRR090 pump and the Kawasaki K5V pump in terms of performance and features, which are as follows:

1. Structural Design:

Danfoss FRR090 pump: Compact and high-pressure open variable displacement piston pump, which adopts a parallel arrangement of axial plungers and sliding shoes, and changes the displacement of the pump by changing the piston stroke by a tilting swash plate. This design allows the pump to achieve high power output in a small space, making it suitable for space-constrained equipment. In addition, the integrated make-up pump on the pump provides the system with supplementary hydraulic oil, cooling oil and pressure oil for control.

Kawasaki K5V Pump: Consists of two swash plate piston pumps connected in series and is fitted with a pilot gear pump to provide controlled oil pressure and power shifting. The internal structure is more complex, but this design allows the pump to work more efficiently and output more power.

2. Performance Parameters:

Pressure & Displacement:

Danfoss FRR090 pump: high pressure level, can meet the needs of a variety of high-pressure working conditions, a wide range of displacement, can be selected according to different application scenarios. For example, in some construction machines with high pressure requirements, the Danfoss FRR090 pump can provide stable power support.

Kawasaki K5V pump: It has a large displacement and high output pressure, and achieves a larger power output by increasing the tilt angle of the swash plate, which can meet the needs of equipment with high power requirements for hydraulic systems such as large construction machinery.

Efficiency:

Danfoss FRR090 pump: High energy efficiency, significantly reducing energy consumption and CO2 emissions, saving energy costs over the long term.

Kawasaki K5V pump: The efficiency is also higher, but comparatively speaking, the Danfoss FRR090 pump may consume less energy under the same operating conditions.

3. Control mode:

Danfoss FRR090 pump: a variety of control methods are available, such as load sensing, pressure compensation, constant power, electronic control, etc., which can meet the specific control requirements of different systems, flexible and convenient operation, and can be accurately controlled and adjusted according to actual work needs.

Kawasaki K5V pump: Equipped with a regulator to adjust the displacement, and equipped with control elements such as electromagnetic proportional pressure reducing valves, it can effectively control the output flow and pressure of the pump, but it may be relatively weaker than the Danfoss FRR090 pump in terms of the diversity of control methods.

4. Applications:

Danfoss FRR090 pump: widely used in construction machinery, agricultural machinery, mining machinery, petroleum equipment and other industries, such as cement mixer trucks, concrete pump trucks, road mixers, cold recyclers and other equipment.

Kawasaki K5V pump: Mainly used in excavators, concrete pump trucks and other large construction machinery, as well as some equipment with high requirements for hydraulic system power, such as some excavator models of Sany use Kawasaki K5V pump.

5. Reliability and Durability:

Danfoss FRR090 pump: As a well-known brand, Danfoss' products have high standards in material selection and manufacturing process, which makes FRR090 pump have good reliability and long service life, and can operate stably in harsh working environments.

Kawasaki K5V Pump: After years of market verification, Kawasaki K5V pump also performs well in terms of reliability and durability, especially the design of its internal structure and the selection of parts and materials, so that it can withstand high working pressure and frequent use.
