Ordering Information: The pump configuration is identified by an alphanumeric code specifying series, displacement, shaft end, rotation direction, seals, mounting flange, and control options. It is crucial to refer to the catalog for accurate code completion.
Displacement Specifications: The document outlines the displacement range for various pump models, from 0 cm³/rev to 93 cm³/rev. Availability of through drive options is specified for each displacement category, with certain configurations marked as available or not available.
Maximum and Minimum Displacement Limitations: Maximum displacement is limited to 93 cm³/rev, while minimum displacement starts from 0 cm³/rev. Specific configurations are available for different displacement ranges.
Through Drive Configurations: Various through drive options are available, including SAE A, B, B-B, C, and C-C configurations. These are applicable to different displacement models, with some configurations not available for certain models.
Tandem Pump Assemblies: Tandem pump combinations are available with through drive configurations such as SAE A, B, B-B, and C. Specific configurations are recommended for tandem combinations with the S5AV pump series.

Operating Curves: The document includes operating curves representative of standard production, tested with mineral oil ISO VG 46 at 50°C.
Pressure Control Devices: Pressure control devices maintain constant pressure in the hydraulic circuit, with calibration fields between 50 and 350 bar. The pressure relief valve must be set at least 20 bar higher than the control device setting.
Load Sensing Control: Load sensing control devices adjust pump displacement based on working pressure, maintaining a constant pressure drop across a restrictor. Calibration ranges for Δp are between 18 and 35 bar.
Dimensions: Dimensions for the S5AV 032/045 pump and controls are provided, including mounting flange specifications and port sizes.
Specifications: The document provides detailed specifications for various models of the S5AV pump series, including S5AV 032/045, S5AV 050/063, and S5AV 075/093. Each model is described with its mounting flange type, control options, and port specifications. The ports include pressure, suction, case drain, gauge, case vent, bearing flushing, load sensing, and remote ports, with dimensions provided in BSPP and SAE standards.
Procedures: The document outlines the procedures for using the through drive feature, which allows the connection of a second pump. It specifies the available flanges and the maximum permissible torques for the drive shaft and through drive.
Standards: The document references several standards, including ANSI B92.1a-1976 for splined shafts and UNI 6604-A for parallel with key shafts. It also mentions DIN 5480 for splined shaft options.
Recommendations: Users are advised to refer to specific control models (e.g., PCXXX, NLP0X-NLP1X) for ports not explicitly shown. The document emphasizes the importance of adhering to operating limits and assessing application conditions to ensure safety.
Dimensions: Dimensions for pumps and controls, through drives, and tandem combinations are provided in both metric and imperial units. Specific dimensions are given for different pump sizes and configurations.
Warnings: The document includes warnings about the effective torque value on the first pump's shaft, which is the sum of the torques required by each pump in the system. It also highlights the limitations on shaft options for tandem pump configurations.
Legal and Usage Notes: The document states that the technical features are non-binding and subject to change without notice. It prohibits reproduction without written consent and directs users to the company's website for general terms and conditions of sale.

SH5AV Pumps-2

DESCRIZIONE - CARATTERISTICHE DESCRIPTION - FEATURES La S5AV è una pompa a pistoni assiali per circuito aperto studiata per applicazioni mobili e industriali. La pompa è dotata di un gruppo rotante che permette di raggiungere elevate pressioni di funzionamento continuo e di picco. Il sistema brevettato di sostentamento idrostatico dei pattini dei pistoni, assicura minimi trafilamenti e, quindi, elevati rendimenti volumetrici. Il sistema di limitazione della cilindrata massima e minima permette di adattare le caratteristiche di portata della pompa alle esigenze dell'impianto. I sistemi di regolazione...
