The Casappa BAP32.40 is a premier example of Industrial Hydraulic Pump engineering,specifically designed as a fixed-displacement Bent Axis Pump to deliver reliable performance in the most challenging environments.This model is part of Casappa's STRADA series,renowned for its application in mobile and industrial machinery such as cranes and material handling vehicles.With a robust design that includes a peak pressure rating of 400 bar and a peak operating speed of 2200 rpm,this Bent Axis Pump is built for endurance and high efficiency.Its axial piston design,characterized by a bent axis configuration,ensures superior volumetric efficiency and consistent fluid displacement,making it an ideal power source for a wide array of high-pressure hydraulic systems.

1 In-Depth Technical Overview and Operating Principle
The Casappa BAP32.40 operates on the fundamental principle of a Bent Axis Pump.In this design,the cylinder block and the drive shaft are arranged at an angle to each other.Pistons,housed within the cylinder block,are connected to the drive shaft flange via a link.As the shaft rotates,this angular arrangement forces the pistons to reciprocate within their bores.This reciprocating motion is what draws hydraulic fluid in during the suction stroke and expels it at high pressure during the discharge stroke,thereby converting mechanical power into hydraulic energy.
This specific Industrial Hydraulic Pump is engineered for fixed displacement,meaning the volume of fluid it delivers per revolution is constant.The"32.40"in its model name likely corresponds to its nominal displacement of 40.9 cm³/rev(or 40 cm³/rev),a key parameter for system designers to match the pump's output to their specific flow requirements.The pump is designed to operate with mineral-based hydraulic oils that conform to DIN 51524 standards,and it requires a fluid cleanliness level of NAS1638 class 8 to ensure longevity and reliable operation.
2 Core Design Features and Construction
2.1 Robust Construction for Heavy-Duty Applications
The BAP32.40 is built with durability as a primary focus.Its construction utilizes high-strength materials to withstand the high operating pressures and the mechanical stresses inherent in heavy machinery.The bent axis design itself is known for its ability to handle higher loads and pressures compared to some other pump types,contributing to a long service life.The pump's design includes a rotating group that is precisely machined to minimize internal leakage,which is critical for maintaining high volumetric efficiency,especially under high pressure.
2.2 Installation and Configuration Flexibility
A notable feature of the STRADA series,to which the BAP32.40 belongs,is its versatile mounting capability.The pump's end cover can be rotated 180 degrees,either clockwise or counterclockwise.This flexibility allows system designers to orient the inlet and outlet ports in the most convenient way for their specific machine layout,simplifying hydraulic system integration and reducing potential hose and fitting complications.Furthermore,the pump is designed for direct installation on Power Take-Off(PTO)units,a common feature in mobile equipment,making it a compact and integrated power solution.
3 Performance Specifications and Capabilities
The performance profile of the Casappa BAP32.40 Bent Axis Pump is defined by several key parameters that make it suitable for high-demand tasks.It boasts a peak pressure rating of 400 bar(5,800 psi),allowing it to generate the high forces required for lifting,pressing,and other intensive work functions.Its continuous operating pressure is 350 bar(5,075 psi),ensuring dependable performance under sustained loads.
The pump can achieve a peak rotational speed of 2200 rpm,with a maximum self-priming speed of 1700 rpm,enabling it to be coupled with a range of prime movers.It is designed to function effectively within a wide hydraulic fluid viscosity range,from 10 cSt to 400 cSt,and can operate with fluid temperatures up to 80°C(176°F).This combination of high pressure,respectable speed,and thermal resilience makes this Industrial Hydraulic Pump a versatile and powerful component.

Beyond lifting equipment,this pump is well-suited for a variety of dump trucks,transport vehicles,and industrial material handling equipment.The reliability and high efficiency of this axial piston pump also make it a candidate for use in certain stationary industrial applications,such as in presses or other machinery requiring a robust and continuous hydraulic power supply.
5 Operational Advantages and Economic Benefits
5.1 High Efficiency and Power Density
The bent axis design of the Casappa BAP32.40 is inherently efficient.The direct mechanical connection for piston reciprocation minimizes energy losses,resulting in high volumetric and overall efficiency.This means more of the input mechanical power is converted into useful hydraulic power,reducing fuel consumption in vehicle applications or electricity usage in stationary setups.Furthermore,this design allows for a very compact package relative to its power output,providing a high power density that is crucial in space-constrained mobile machinery.
5.2 Enhanced Reliability and Lower Lifecycle Costs
Built with robust materials and precision engineering,this Industrial Hydraulic Pump is designed for a long operational life with minimal maintenance needs.Its ability to handle high pressures and its tolerance for a range of operating conditions contribute to exceptional system uptime.The resulting reduction in unplanned maintenance and longer service intervals directly translate to lower total cost of ownership,providing significant economic benefits over the pump's lifecycle.
5.3 Low Noise Operation
The BAP32.40,as part of a modern hydraulic pump series,is engineered for low noise emission.This is a critical advantage in both industrial and urban environments where noise pollution is a concern.Lower operational noise also contributes to a better working environment for machine operators and is often an indicator of refined hydraulic performance and reduced mechanical stress.
Frequently Asked Questions(FAQs)
What is the key difference between a bent axis pump and a swashplate pump?
Both are types of axial piston pumps,but they operate on different principles.A swashplate pump uses a tilted plate against which piston slippers ride to create the reciprocating motion.The Casappa BAP32.40 is a Bent Axis Pump,where the pistons'reciprocation is caused by the angular difference between the cylinder block and the drive shaft.Bent axis designs are often noted for their high efficiency and ability to handle higher pressures and loads,making them exceptionally robust for demanding industrial applications.
Can the displacement of the BAP32.40 be adjusted?
No,the Casappa BAP32.40 is a fixed-displacement axial piston pump.Its displacement of approximately 40 cm³/rev is a constant design feature.If a variable flow output is required for an application,a different model from Casappa's variable displacement pump series would need to be selected.
What type of hydraulic fluid is recommended for this pump?
This Industrial Hydraulic Pump is designed to operate with standard mineral-based hydraulic oils that meet DIN 51524 specifications.It is crucial to maintain the fluid's viscosity within the recommended range of 10 to 400 cSt and ensure a high level of fluid cleanliness(NAS1638 class 8 or better)to ensure optimal performance and maximize the pump's service life.
Is the BAP32.40 suitable for use in open-circuit hydraulic systems?
Yes,the Casappa BAP32.40 is typically applied in open-circuit hydraulic systems.In such a system,the pump draws fluid from a reservoir and pressurizes it to actuate components like cylinders or motors,after which the fluid returns to the reservoir.Its design is well-suited for this common system architecture.
How does the rotating end cover benefit the installation?
The feature that allows the end cover to be rotated 180 degrees provides significant installation flexibility.It enables engineers to position the hydraulic ports in the most optimal orientation for their specific machine design.This simplifies plumbing,reduces potential hose stress,and allows for a cleaner and more compact overall system layout.
