Hydraulic pumps are a vital part of hydraulic systems, determining flow rate, pressure and efficiency. The A2FO series from Bosch Rexroth is an axial piston fixed pump designed for industrial applications. This blog post will explain the main specifications, performance features and applications of the A2FO axial piston fixed pump.
A2FO Series Overview
The A2FO series is an axial piston fixed pump, meaning the pumping pistons are arranged axially along a shaft rather than radially. Some key details:
- Piston design: The pistons are oriented parallel to the pump shaft and move axially in and out of cylinder bores to pump fluid.
- Монтаж: The pumps are designed for fixed mounting to a system, rather than mounting on a swing plate.
- Контроль: The delivery flow rate can be controlled by either rotating the shaft speed or tilting the swashplate angle.
- Функции: The pumps offer high efficiency, smooth flow, good controllability and compact design.
- Media: The pumps can handle various hydraulic fluids like mineral oils, HFA fluids and fire-resistant fluids.
- Output: The A2FO series provides flow rates from 0.4 к 110 L/min and pressures up to 350 бар.
