Frequently Asked Questions
How durable is it? How long does it last?
+
-
Hardened gears + sliding bearings: impact-resistant and wear-resistant, with automatic clearance compensation. Efficiency declines slowly over time, and with proper maintenance, the service life far exceeds that of standard gear pumps.
Are the requirements for the hydraulic fluid stringent? How resistant is it to contamination?
+
-
Gear pumps feature a simple design and have relatively low requirements for fluid cleanliness, making them suitable for hydraulic systems in construction machinery, agricultural machinery, and machine tools operating under less-than-ideal conditions.
What about the warranty and after-sales service?
+
-
Products purchased through official channels come with the manufacturer's warranty, and aftermarket parts are widely compatible, making repairs and replacements convenient.
What types of equipment is it primarily used in?
+
-
CNC machine tools, hydraulic power units, hydraulic fixtures, small construction machinery, agricultural machinery, and auxiliary systems for injection molding machines; applications requiring low flow rates, medium to high pressure, and stable, reliable performance.
How high can the pressure go? Is that enough?
+
-
Rated pressure: 200 bar, peak pressure: 250 bar, suitable for most machine tools, hydraulic power units, and small construction machinery applications.
Basic Information
The product model is AZPF-11-008RRR20KB-S0081, with material code 0510425041. It belongs to the Rexroth AZPF series of external gear pumps, is a fixed-displacement type, and has 12 teeth.
Key Performance Parameters
Displacement is 8 cm³/rev, rated continuous operating pressure is 250 bar, short-term overload intermittent pressure is 280 bar, and the typical maximum speed is 3000 rpm (subject to slight variation depending on operating conditions). It features a sliding bearing design, supports dry start-up, and delivers excellent low-speed performance. High-pressure gap seals ensure efficient operation with low heat generation.
Structural and Installation Parameters
Viewed from the shaft end, the rotation direction is clockwise. The shaft extension is an SAE J744 16-4 (9T 16/32DP) spline shaft. The mounting flange is an SAE J744 82-2 (A) two-hole flange, and the oil port is a square flange compliant with ISO 8434-1. The unit is designed for high-precision manufacturing and features a long service life, with support for custom ISO/SAE shaft extensions.
Model Designation Explanation
In the model number AZPF-11-008RRR20KB-S0081, AZPF represents the F-series external gear pump, 11 denotes the size series, 008 corresponds to a displacement of 8 cm³/rev, RRR indicates clockwise rotation + SAE spline shaft + 2-hole flange configuration, and 20KB is the port and mounting detail code. and S0081 denotes the version and seal configuration.
Typical Applications
Primarily used in industrial hydraulic systems (such as machine tools, injection molding machines, and hydraulic power units), auxiliary systems for construction machinery, vehicle hydraulic power units, as well as low- to medium-pressure open and closed circuits.
