Uchida Hydraulic Pump Catalogue Pdf Top [2021] Here

Uchida hydraulic pumps, now primarily integrated under the Bosch Rexroth brand, are renowned for their high-pressure performance and durability in mobile machinery. Overview of Top Uchida Hydraulic Pump Series

Uchida's product line is characterized by its axial piston designs, which are industry standards for excavators and heavy construction equipment. AP2D Series:

Application: Primarily used in mini-excavators (1.5 to 5 tons).

Features: This is a double-variable displacement piston pump with an additional gear pump. It is designed for compact spaces while maintaining high efficiency. A10V / A10VO Series: Application: General industrial and mobile hydraulics.

Features: Known for medium-pressure applications, these pumps offer good suction characteristics and low noise levels. A4V Series: Application: High-pressure closed-circuit drives.

Features: Swashplate design allows for infinitely variable flow, commonly found in travel drives for heavy machinery. Key Specifications & Performance uchida hydraulic pump catalogue pdf top

Based on the standard technical documentation found in Uchida-Rexroth catalogs, these pumps share several high-end technical traits:

Displacement Range: Varies from small 10cc units to large-scale 250cc+ models.

Operating Pressure: Nominal pressures typically range between 250 bar (3,625 psi) and 350 bar (5,076 psi), with peak pressures reaching up to 400 bar.

Mounting Standards: Most utilize SAE or ISO standard mounting flanges and shafts for easy replacement and integration. Maintenance and Catalog Access

Since Uchida was acquired by Rexroth, most "top" PDF catalogs are now hosted under the Bosch Rexroth technical documentation portal. Uchida hydraulic pumps, now primarily integrated under the

Seal Kits: When searching for parts, catalogs often specify "Uchida-Rexroth" kits to ensure compatibility with older Japanese-manufactured units.

Identification: Always check the Type Code on the pump's nameplate (e.g., AP2D25LV1RS), as this specifies the exact displacement, control device, and rotation required for a matching replacement.

Uchida Hydraulic Pump Catalogue: A Complete Guide to Top Models and PDF Resources

Uchida Hydraulics, a subsidiary of the Bosch Rexroth Group, is a premier manufacturer of high-performance hydraulic components. Known for merging Japanese precision with German engineering, Uchida pumps are essential in sectors like construction, marine, and mining. This guide explores the most sought-after models, their technical specifications, and where to find official Uchida hydraulic pump catalogue PDFs. 1. Top Uchida Hydraulic Pump Models

Uchida's product line is extensive, ranging from axial piston pumps to specialized gear units. These models are frequently used as original equipment in heavy machinery brands like Komatsu and Hitachi. A7V Hydromatik Rexroth Pump Overview | PDF - Scribd Where to Find the Top Uchida Hydraulic Pump

Where to Find the Top Uchida Hydraulic Pump Catalogue PDF

Unlike generic manuals, the "top" Uchida catalogues are not always on the first page of Google. Here is a strategic approach to finding the highest-quality PDF:

📘 Why "TOP" Matters

When a technician searches for the top of a catalogue PDF, they likely want:

  1. Model numbering system – Decoding Uchida's naming logic (e.g., UCHIDA-AP-22-V-R).
  2. Flow & pressure specs – Top pages often summarize the entire range.
  3. Cross-section diagrams – For seal kit or rotating group identification.
  4. Compatibility notes – "Which Uchida pump replaces a Rexroth or Eaton?"

3. Uchida GPP Series (Gear Pumps)

  • Models: GPP-12, GPP-20, GPP-25, GPP-32, GPP-40
  • Key Features: Fixed displacement, bi-rotational options.
  • Catalogue Must-Have: Flow ripple charts and viscosity range charts.

Note: In 2005, Uchida’s hydraulic division merged with Sunfab (Sweden). Therefore, many "top" catalogues are archived under the Sunfab name but still reference Uchida model codes. A truly top-tier PDF will include a cross-reference section.

2. Cross-Referencing with Sunfab

The top PDF will list both old Uchida and new Sunfab part numbers. For example, a Uchida AP-22 may cross to Sunfab SC-46. This is gold for procurement.
