Overview

This document provides detailed technical specifications and product information for hydraulic pumps and cylinders designed for industrial applications. It covers various types of hydraulic cylinders (single acting, double acting, hollow plunger) and pumps (manual and air-hydraulic), including their capacities, pressures, dimensions, and optional accessories.

1. Single Acting Hydraulic Cylinders

These cylinders operate with hydraulic pressure on one side of the piston and use gravity or spring return for the opposite stroke. The document lists multiple models (e.g., 359, 360, 361 series) with varying tonnage capacities from 5 to 50 tons, oil capacities ranging from approximately 0.6 to 7.1 liters, and maximum operating pressures of 520 to 640 bar.

Dimensions (A, B, C, D) and oil capacities are provided for each model, with options for low height (compact) designs and different return mechanisms (gravity or spring).

2. Long Stroke Single Acting Cylinders

Models such as 359/EM to 363/HM offer extended stroke lengths for applications requiring greater piston travel. These cylinders maintain similar tonnage ratings but have increased oil capacities (up to 2355 cm³) and larger dimensions. Thread sizes and mounting details are specified for precise integration.

3. High Tonnage Cylinders

Heavy-duty cylinders (models 364/M to 368/DM) are designed for higher load capacities (up to 245 tons) with oil capacities up to 7 liters and pressures up to 520 bar. These cylinders feature robust construction and larger dimensions to handle demanding industrial tasks.

4. Double Acting Hydraulic Cylinders

Double acting cylinders (models 366 to 367/C) provide hydraulic power on both sides of the piston for controlled movement in both directions. Capacities range from 12 to 37 tons, with oil volumes from 15 to 760 cm³ and pressures up to 640 bar. Detailed dimensions and thread specifications are included for each variant.

5. Hollow Plunger Cylinders

These single and double acting cylinders feature a hollow piston design to allow passage of rods or cables through the cylinder. Models 369 series and 367 series are detailed with oil capacities, pressures (up to 700 bar), and dimensional data, suitable for specialized industrial applications.

6. Manual Pumps

Manual hydraulic pumps (models 350/A to 358/LX) are supplied complete with flexible hoses and quick couplings. They offer various oil displacements per stroke (2.26 to 40 cm³), tank capacities (up to 7500 cm³), and maximum pressures from 520 to 700 bar. Pump types include one-speed and two-speed options, with dimensional data for installation.

7. Air-Hydraulic Pumps

Air-hydraulic pumps (models 357 series) combine pneumatic power with hydraulic output, suitable for higher flow rates (up to 1.4 l/min) and pressures up to 700 bar. They come with hoses and quick couplings, tank capacities ranging from 1100 to 8000 cm³, and include 4-way valves for control.

8. Accessories and Optional Equipment

The document lists additional accessories such as glycerine-filled pressure gauges, base plates, and gauge adaptors to enhance system integration and monitoring. Compatibility with various cylinder models is specified.

Critical Parameters and Recommendations

• Pressure Ratings: Cylinders and pumps are rated between 520 and 700 bar; selecting equipment within these limits is essential for safety and performance.
• Oil Capacity and Displacement: Proper matching of cylinder oil capacity and pump displacement ensures efficient operation.
• Return Mechanisms: Gravity or spring return options are available; choice depends on application requirements.
• Mounting and Dimensions: Detailed dimensional data and thread sizes facilitate correct installation and compatibility.
• Accessories: Use recommended gauges and base plates for accurate pressure monitoring and stable mounting.

Summary

This technical document serves as a comprehensive guide for selecting and specifying hydraulic pumps and cylinders for industrial use. It provides essential data on capacities, pressures, dimensions, and options to ensure proper application and integration in hydraulic systems.
