Applications
Applications
Mobile Material Handling: A primary choice for forklift attachments, pallet trucks, and scissor lifts, where the bi‑directional pump eliminates complex valve circuits and delivers precise lifting/lowering control.
Agricultural Equipment: Optimized for hydraulic steering systems, reversible seeders, and fertilizer spreaders, handling frequent forward/reverse cycles and variable loads in outdoor field environments.
Construction Machinery: Ideal for small excavator attachments, mini‑loader auxiliary circuits, and concrete mixer drives, providing smooth bi‑directional flow for rotating and lifting functions.
Marine & Deck Equipment: Widely used for winches, crane boom controls, and hatch cover systems, where the pump’s corrosion‑resistant aluminum housing and reversible operation suit marine hydraulic applications.
Industrial Power Units: Perfect for compact hydraulic power packs, small press circuits, and test benches, offering efficient, low‑noise bi‑directional flow for lab and light industrial automation.
Specialized Vehicles: Frequently employed in aerial work platforms, tow truck winch systems, and utility vehicle actuators, providing reliable power for reversible linear and rotary motion.
Factory&FAQ
CB2A-F23 pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
The CB2A‑F23 is a high‑efficiency, fixed‑displacement bi‑directional gear pump, part of Bucher’s CB2A Series. Featuring a lightweight aluminum alloy construction, it is specifically engineered for closed‑loop hydraulic systems requiring reversible operation and compact installation.
Reversible Operation: Its internal porting and pressure compensation design allow seamless forward and reverse rotation without additional directional valves.
Compact Closed‑Loop Design: Optimized for use in closed hydraulic circuits, it eliminates the need for complex valve banks, reducing system complexity and response time.
Lightweight Yet Durable Housing: The high‑strength aluminum alloy body provides a superior power‑to‑weight ratio, making it ideal for mobile applications where weight is a critical factor.
The CB2A‑F23 is a reliable medium‑pressure bi‑directional pump. Its typical pressure ratings are:
Continuous Pressure: Up to 180 bar (2,610 psi).
Intermittent/Peak Pressure: Up to 200 bar (2,900 psi).
This robust rating makes it ideal for light‑to‑medium duty mobile and industrial hydraulic circuits.
Yes, the CB2A‑F23 is a high‑quality alternative to other premium bi‑directional gear pumps. It is often used as a replacement or upgrade for:
Bucher CB‑E series pumps
To ensure a successful swap, verify the Mounting Flange (SAE “A”), Shaft Type (20 mm keyed), Port Size (G3/4" BSPP), and Displacement (23.61 cm³/rev) to match your existing system.
To protect the precision gears and seals, the following is recommended:
Oil Type: Premium mineral‑based hydraulic fluids with strong Anti‑Wear (AW) additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 100 to 150 SUS (20 to 30 cSt).
Filtration: A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the gear faces and seals.
The CB2A‑F23 operates within a standard speed range suitable for most mobile applications:
Continuous Speed: 600–2000 rpm.
Maximum Intermittent Speed: 2200 rpm.
Operating within these ranges ensures optimal efficiency and extends the service life of the pump.

CB2A-F23 pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
