Product Advantages
Core Positioning
Ultra-compact variable displacement axial piston pump engineered by Rexroth, tailored for space-constrained industrial scenarios. Its swashplate-driven open-circuit design delivers exceptional flow stability, making it a top choice for small-scale equipment where precision and footprint efficiency are non-negotiable.
Key Performance Metrics
Geometric displacement of 40 cm³/rev, paired with a nominal speed of 2600 rpm. At full displacement, it delivers 104 l/min rated flow and peaks at 170 l/min, with a standard nominal pressure of 350 bar (max 400 bar). Opting for port plate 36 boosts nominal pressure to 380 bar and max pressure to 420 bar, expanding its versatility across light to medium load applications.
Variable Displacement Advantages
Flow output dynamically adjusts with drive speed and swashplate angle, compatible with DR/DP/FR control modules for seamless tuning. Built-in pre-compression volume minimizes pressure pulsation (≤3 bar deviation), while advanced suction technology (0.8 bar absolute minimum inlet pressure) prevents cavitation even in low-fluid conditions. An integrated optical swivel angle indicator enables real-time displacement monitoring for precise system calibration.
Structural & Installation Highlights
Weighing just 39 kg, it features an ISO 3019-2 metric 4-hole flange (Ø125) for easy mounting. SAE J518 ports (1.5 in suction, 3/4 in pressure) come with metric fastening threads (M12×1.75 and M10×1.5), and it supports all installation orientations-vertical mounting (drive shaft upward) requires full fluid filling and air bleeding to avoid dry running. The M22×1.5 R(L) drain port must be connected to the reservoir for effective leakage management.
Fluid & Environmental Adaptability
Compatible with mineral oils (HL/HLP per DIN 51524), flame-resistant fluids (HFC/HFDU), and biodegradable options (HETG/HEES). Operates reliably within a -20~+80°C temperature range, with optimal hydraulic fluid viscosity between 16–36 mm²/s. FKM seals come standard, with NBR/PTFE options available (ordered with code P in position 09) for HFA/HFB/HFC fluids.
Durability & Reliability Features
Modular construction simplifies maintenance, while a low noise level (≤75 dB(A) at nominal speed) enhances operator comfort. The pump withstands 1000 N maximum radial force and 600 N axial force at X/2, ensuring stability under dynamic loads. Backed by Rexroth's MTTFd certification, it requires hydraulic fluid cleanliness of ISO 4406 20/18/15 (19/17/14 for viscosity <10 mm²/s) to maximize service life.
Industry Applications
Ideal for precision compact hydraulic power units, laboratory testing equipment, small robotic arms, and electronic component assembly lines. Excels in medical device manufacturing and packaging machinery where space efficiency, low noise, and pinpoint flow control are critical.
