Product catalog summary

Overview: The document provides comprehensive technical specifications and performance data for Casappa's FORMULA range of hydraulic gear pumps. These pumps are designed for high-pressure applications at low speeds, such as in truck-mounted cranes and lift-trucks. They are available with various mounting flanges and are compatible with different fluid types.

Key Features:

External gear type construction with ISO, Italian, and SAE mounting flanges.
Maximum continuous pressure: 4205 psi (290 bar); Maximum intermittent pressure: 4568 psi (315 bar); Maximum peak pressure: 4713 psi (325 bar).
Maximum speed: 3000 min^-1.
Two-piece cast iron housing for high performance at low speeds.

Specifications:

Displacement ranges from 0.50 in³/rev (8.26 cm³/rev) to 9.20 in³/rev (150.79 cm³/rev).
Fluid temperature range varies based on seal type and fluid composition.
Viscosity range: 60 to 456 SSU recommended, up to 3410 SSU permitted.
Filtering requirements depend on working pressure, with specific contamination classes outlined.

Performance Curves:

Performance data is provided for different pump models (FP 20, FP 30, FP 40) under specified conditions, including temperature and viscosity.
Each model's performance is detailed with maximum pressures and speeds.

Applications and Instructions:

Suitable for various applications requiring high pressure at low speeds.
Instructions for changing rotation and assembling pumps with support are included.

Warnings:

Improper use can cause damage to the product or system.
Ensure the latest issue of the document is used for reference.

Ordering Instructions:

For triple pumps, the length is calculated by summing specific dimensions (A+B+C+B+C+D).
Ordering requires specifying the front, intermediate, and rear pump types, rotation direction, and seal type.
Example: Triple pump FP40•63-06S8-LOF/OD/ 40•63-LOF/OD/40•63-LOF/OD S-0-N.

Torque and Port Specifications:

GAS Straight Thread Ports: Torque values range from 15 +1 Nm (133 ÷ 142 lbf in) to 70 +5 Nm (620 ÷ 664 lbf in) depending on the port code.
SAE Straight Thread Ports: Torque values range from 15 +1 Nm (133 ÷ 142 lbf in) to 40 +2.5 Nm (354 lbf in).

Key Dimensions:

Dimensions for various pump types are provided in both millimeters and inches, with specific port codes for IN and OUT configurations.
ISO and SAE versions have specific dimension adjustments, such as A (Z0) being A (19 T) + 11.5 mm (0.453 in).

Additional Notes:

Special versions are available for applications with specific load requirements on the drive shaft.
Seals should be chosen based on temperature requirements as indicated on page 3 of the document.

Procedures:
The document provides detailed instructions for changing the rotation of unidirectional pumps, including steps for disassembling and reassembling components, ensuring proper alignment, and checking for free rotation.

Installation Instructions:
Guidelines are provided for the installation of pumps, emphasizing the importance of matching the direction of rotation with the drive shaft, ensuring proper alignment, and avoiding axial or radial loads. Recommendations for tank capacity, line diameter, and filter usage are also included.

Hydraulic Fluid and Starting Up:
Recommendations for hydraulic fluid usage are provided, including avoiding mixtures of different oils. The starting up procedure includes checking connections, bleeding the circuit, and gradually increasing pressure and speed.

Maintenance:
Regular maintenance is advised, including keeping surfaces clean, replacing filters, and checking oil levels. The document emphasizes the importance of maintaining clean fluid to ensure system longevity.

Additional Information:
The document notes that specifications may change without notice as part of continuous product improvement. Contact information for CASAPPA S.p.A. is provided for further inquiries.
