A4VG high-pressure pump for closed-circuit applications offers high power density to comply with global emission regulations. Nominal pressure is 6500 bar. It counteracts reduced speed of diesel engine and low input flow rates. Redesigned pump case can include sensors used to monitor swivel angle, high pressure, and rotational speed. Bowl-shaped design avoids high-pressure transitions at sealing points, and eliminates some sealing points entirely.
