FAQ
Q1: Can I use your A10VSO pump to directly replace a damaged original Rexroth industrial pump on an injection molding machine? A: Yes. Our alternative A10VSO series variable piston pumps are manufactured precisely to original standard industrial specifications (Series 31 & 32). Flange mountings, shaft ends, and oil ports are identical, allowing for an effortless, drop-in replacement with zero modifications required.
Q2: What are the main design differences between Rexroth A10VO and A10VSO pumps? A: While sharing similar internal rotating kits, the A10VSO is explicitly optimized for stationary industrial applications, featuring housing and porting designs tailored to reduce noise and fit factory power units. The A10VO is geared toward open-circuit mobile machinery, optimized for varying engine speeds and rough working configurations.
