▶ Series 6

▶ Size 32 … 180

▶ Nominal pressure / Maximum pressure: 400 / 450 bar

▶ Open circuit

▶ Fixed pump with axial tapered piston rotary group of bent-axis design, for hydrostatic drives in an open circuit

▶ For use in mobile and stationary applications

▶ The flow is proportional to the drive speed and displacement

▶ The drive shaft bearings are designed for the bearing service life requirements usually encountered in these areas

▶ High power density

▶ Small dimensions

▶ High total efficiency

▶ Economical design

▶ One-piece tapered piston with piston rings for sealing

• ▶ NG45: Extreme Angular Acceleration Outlier Within the entire NG32–180 range, the size 45 stands out with a maximum angular acceleration of 14600 rad/s² - nearly double the next-highest value (7500 rad/s² at NG56/63) and more than four times the NG160/180 rating. This exceptional dynamic capability suits high-frequency stamping presses, injection molding clamp units, and other cyclic-duty machines where start-stop response time directly governs production cycle efficiency.

  ▶ Mass Plateau: Free Displacement Upgrades The Series 6 range features four distinct mass plateaus - 9.5 kg (NG32), 18 kg (NG56/63), 32 kg (NG107/125), and 45 kg (NG160/180). At each plateau, the larger size delivers more displacement, flow, and torque at zero additional weight. For example, selecting the NG125 over the NG107 gains 18 cc/rev (+17%) and 29 L/min flow - with no change to mounting footprint or installed mass. This allows upsizing without re-engineering the surrounding structure.

  ▶ Port Plate Configuration Matrix Four port plate codes - PPB, PBB, VPB, VBB - cover the installation spectrum:

  P prefix: threaded ports (DIN 3852) for compact plumbing

  V prefix: metric flange mounting per ISO 3019-2 with rear suction

  B suffix: parallel keyed shaft (DIN 6885)

  P suffix: splined shaft (DIN 5480)

  This matrix enables the pump to be oriented and connected in tight machinery envelopes - side-entry service lines with rear suction, or rear-entry with side drainage - without rerouting existing piping layouts.

  ▶ Full Torque Spectrum in One Series From 204 Nm (NG32) to 1146 Nm (NG180), the A2FO Series 6 spans a 5.6× torque range within a single product family sharing identical bent-axis architecture, sealing philosophy, and bearing design principles. Equipment manufacturers serving multiple market segments - from mini-excavator auxiliary pumps (NG32) to marine winch and crane main drives (NG160/180) - can standardize on one pump series across their product line, reducing spare parts inventory and service training overhead.

▶ Can I order multiple sizes from this range in a single shipment?

Yes. We accept mixed-size orders within the A2FO Series 6 range. Contact us with your size and quantity requirements for a consolidated quotation and shipping arrangement.

▶ What warranty terms apply across the NG32–180 range?

All sizes carry a standard 12-month warranty from delivery date, covering material and manufacturing defects under specified operating conditions (pressure, speed, fluid cleanliness within published limits).

▶ Is sample availability guaranteed for every size?

Samples for popular sizes (NG32, NG45, NG63, NG80) are typically available from stock. For less common sizes, lead time depends on current production scheduling - please inquire for specific availability.

▶ How should I select the correct A2FO size for my hydraulic circuit?

Match the required flow at your prime-mover speed to the nominal flow column in the Technical Specifications table. If your engine runs at 1800 rpm and you need approximately 145 L/min, the NG80 is the direct match. Always verify that torque demand stays within the rated value at your operating pressure.

▶ What do the port plate codes (PPB, PBB, VPB, VBB) mean in the ordering code?

The first letter (P or V) indicates port plate type - P for threaded connections (DIN 3852), V for metric flange mounting (ISO 3019-2) with rear suction. The second letter (P or B) specifies the drive shaft - P for splined (DIN 5480), B for parallel keyed (DIN 6885). The final digit sequence (05 or 06) denotes the shaft seal material and standard version configuration.
