Built for Resilience in Demanding Environments
The AL A10VO pump is synonymous with durability, backed by a comprehensive one-year warranty. Its design is focused on providing superior resistance to extreme pressure shocks, abrasive contamination, and harsh operating conditions. In the dusty, high-vibration environment of a construction site, its robust construction—featuring hardened components and advanced sealing technologies—ensures unwavering performance. This resilience, critical for parts like 20/602100, directly translates to extended service intervals and maximum machine uptime for equipment from leading manufacturers like JCB (jcb.com).

Powering the Versatile JCB Equipment Range
The intelligence and compact design of the AL A10VO pump make it an ideal power source across the diverse spectrum of JCB machinery, renowned for its application in construction, agriculture, and specialized industries.

• Compact and Mid-Size Excavators: In machines like the JCB 3CX backhoe loader and the robust JS series excavators, this pump serves as the main hydraulic source, providing the precise, high-pressure flow needed for simultaneous digging, lifting, and swing movements. Its load-sensing capability is key to the machine’s fuel efficiency and smooth operation, with configurations often referenced under part numbers like 20/914100 and 20/912200.
• Telehandlers and Access Platforms: JCB’s extensive range of Loadall telehandlers relies on steady hydraulic power for lifting, extending, and precise positioning. The AL A10VO hydraulic pump delivers this performance reliably.
• Specialized and Defense Equipment: From JCB’s high-speed tractors to its specialized military engineering vehicles, durable and intelligent hydraulics are paramount. The pump’s ability to perform under variable and severe loads supports these unique applications.
• Global Parts and Service Support: The pump’s integration across JCB models is confirmed by its common presence in global parts systems under various codes, including 332/U2812, 332/U0900, and 20/950303, facilitating maintenance and service worldwide.

FAQ (Frequently Asked Questions)

Q1: What is the primary advantage of using a variable displacement pump like the AL A10VO as a main pump?
A1: Its key advantage is efficiency. Unlike fixed pumps, it automatically adjusts its output flow to precisely match the system’s real-time demand through load-sensing control. This eliminates wasteful energy conversion to heat, significantly reducing fuel consumption and allowing for cooler, more responsive hydraulic operation.

Q2: How does the “AL A10VO” designation enhance this pump for excavator applications?
A2: The AL A10VO variant is specifically engineered for severe-duty, long-life applications. It typically incorporates enhanced materials, upgraded bearing systems, and improved contamination resistance, making it exceptionally capable of handling the constant pressure shocks, high cycles, and abrasive environments inherent to excavator work.

Q3: Can this pump withstand the shock loads from a hydraulic hammer or during aggressive digging?
A3: Absolutely. The pump’s robust internal design, including its pressure-compensated control and heavy-duty rotating group, is built to absorb and manage the severe pressure transients and shock loads generated during such operations, protecting the entire hydraulic system.

Q4: We need a replacement main pump for our JCB excavator, identified by part number 332/U0900. Can you supply it?
A4: Yes. We provide high-quality, cross-compatible hydraulic pump solutions for JCB and other major OEM equipment. For precise technical specifications and compatibility verification for part 332/U0900 or 20/950303, please contact our engineering team via www.baolilai-pump.com/contact_us/.
