Lamborghini HLPD series gear pumps with integrated relief valves

The Lamborghini HLPD series gear pump incorporates an integrated direct acting pressure relief valve within its rear cover. This structural layout protects hydraulic circuits against sudden pressure spikes and excessive overloads, ensuring dependable fluid system operation.

Built in adjustable relief valve mechanism limiting peak circuit pressure
Displacement capacities spanning from one to sixty cubic centimeters per turn
Resilient continuous performance under fluid pressure levels reaching 280 bar
Extruded aluminum alloy body paired with specialized anti friction bushings

Lamborghini HLPS series standard external gear hydraulic pumps

The HLPS series consists of standard external gear hydraulic pump units equipped with solid rear covers without internal relief valves. These models are engineered for stationary power units, industrial machine drives, and mobile mobile machinery fluid supply lines.

High hydromechanical efficiency reaching 92 to 94 percent across duty cycles
Tapered and splined drive shafts conforming to European and SAE standards
Flanged connection ports ensuring dependable fluid line sealing under strain
Hydraulic axial clearance compensation maintaining optimal tooth gear mesh

Lamborghini MLPD and MLPS modular hydraulic pumps and fluid motors

The compact modular MLPD and MLPS fluid unit series are developed to drive auxiliary mechanisms across mobile machinery and plant installations. These units provide low operational sound levels, uniform oil displacement, and bi directional fluid motor capability.

Compact installation dimensions fitting into restricted machine envelope space
Bi directional hydraulic motor capability supported by external drain ports
Uniform volumetric flow minimizing output ripples across low speed rotations
High precision gear teeth machined from alloy steel with thermal hardening

Lamborghini pressure relief, check, and sequence hydraulic valves

Lamborghini Oleodinamica valve hardware delivers accurate pressure and flow regulation throughout industrial hydraulic circuits. The range comprises in line and cartridge style relief valves, adjustable flow regulators, and single direction pilot operated check valves.

Direct acting and pilot operated relief valves delivering precise setpoints
Stable maintenance of calibrated pressure thresholds without internal leakage
Threaded cartridge form factors for direct cavity installation into manifolds
Protective anti corrosion exterior surface treatment on forged steel bodies

Mounting flanges, drive couplings, and hydraulic seal overhaul kits

To ensure rigid alignment between hydraulic pumps and prime mover electric motors or combustion engines, bell housings, flexible spider couplings, and mounting flanges are manufactured. Comprehensive elastomeric seal overhaul kits restore pump volumetric tightness.

Standard European four bolt mounting flanges and SAE pilot adapter plates
Flexible drive shaft couplings compensating for angular and axial misalignment
Molded fluoroelastomer shaft seals and shaped profile rings for fluid blocks
Maintenance overhaul packages containing seals and backup rings for pumps

Manufacturing history, reliability criteria, and Argelato plant operations

Founded in 1969 by Ferruccio Lamborghini, Lamborghini Oleodinamica established a high precision production facility in Argelato, Bologna.

The enterprise was created to deliver specialized hydraulic power units, fluid pumps, and control hardware to agricultural machinery and industrial vehicle manufacturers.

Under the leadership of Tonino Lamborghini, the plant developed modular gear pump designs featuring hydrodynamic tooth profiles and floating thrust plates. The historical plant building was later converted into the Ferruccio Lamborghini Museum, preserving the engineering heritage of the brand.

HLPD series design features and internal pressure relief valve calibration

Lamborghini HLPD series gear pumps feature a direct acting pressure relief valve built directly into the rear pump cover.

This integrated layout eliminates external piping requirements while protecting the delivery line against sudden pressure surges when hydraulic cylinders reach mechanical stroke limits.

The adjustment screw is sealed with a protective cap and locknut to secure the calibrated pressure setting. During machine assembly, the relief threshold is verified with a master pressure gauge, ensuring overload protection for fluid motors while avoiding excessive oil heating.

Hydromechanical efficiency and axial clearance compensation in HLPS pumps

The standard HLPS series utilizes hydrodynamic compensation for axial gear face clearances. Operating fluid pressure is routed to balancing chambers behind floating side bushings, pressing them against gear faces with proportional force to maintain hydromechanical efficiency around 92 to 94 percent.

Bushings are manufactured from low friction bearing bronze with solid lubricant deposits, protecting against dry friction during cold pump startups. Precision gear tooth finishing minimizes high frequency fluid pressure ripple and vibration along rigid machine pipework.

Drive alignment standards and prevention of radial input shaft side loads

Lamborghini external gear pumps are engineered to transmit torque via flexible couplings or direct splined shaft engagement. Radial and axial side loads on the drive stub must be strictly prevented, as excessive lateral force accelerates journal bearing wear and compromises the front shaft seal.

When mounting pump flanges onto electric motor bell housings, radial and angular alignment error must remain below 0.05 mm. Belt or chain drives must incorporate independent intermediate bearing blocks with paired angular contact bearings to isolate external tension from the pump.

Hydraulic fluid quality standards and recommended filtration thresholds

Service life of HLPD, HLPS, and MLPS gear pumps depends directly on fluid cleanliness. Premium petroleum based hydraulic fluids with kinematic viscosity between 20 and 100 cSt are recommended, maintaining a solid contamination level no coarser than ISO 4406 cleanliness rating 19/16.

Suction lines require a strainer mesh no tighter than 125 microns to prevent pump cavitation, while return or pressure lines must include high efficiency filter elements with an absolute rating of 10 to 25 microns. Periodic oil renewal prevents degradation of elastomeric fluid seals.

Multiple pump tandem configurations and periodic seal maintenance rules

The modular construction of Lamborghini pumps enables multi section tandem assemblies to feed independent hydraulic circuits simultaneously. Pump sections are coupled through internal splined drive sleeves and spigot pilots, providing rigid mechanical alignment within a compact footprint.

Routine servicing involves inspecting drive shaft lip seals and replacing shaped housing profile rings using manufacturer overhaul kits. Tightening bolts must be torqued to specified torque values in diagonal sequence to avoid housing distortion or gear binding.
