Product Introduction
ATUS PFB/PVB Series swash plate axial piston pumps cover fixed displacement PFB and variable displacement PVB models, designed for open-circuit industrial hydraulic systems. PFB is fixed displacement pump with stable constant flow output; PVB variable pump can adjust flow automatically to match system demand. Displacement options from 10.5cc to 197.5cc, continuous working pressure up to 210 bar. Widely recognized for high efficiency, stable pressure performance and interchangeable structure, ideal direct replacement for original hydraulic pumps for industrial equipment.

Advantages
Drop-in replacement design, standard mounting dimensions, minimal modification during retrofit
PVB variable pump automatically adjusts flow to match load demand, saving energy and reducing operating cost
PFB fixed pump delivers stable constant flow, suitable for constant-duty industrial cycles
Robust bearing system, withstands pressure fluctuation and intermittent shock loads
Low flow pulsation, reduces vibration and protects valves, pipelines and actuators
Modular control assembly, flexible to switch control types according to working requirements
Wide displacement range, one series covers multiple flow requirements for different machines
Simple internal structure, easy on-site inspection and component replacement
100% pressure tested before delivery, consistent batch quality and reliable performance
ATUS global technical support, fast spare parts supply for after-market maintenance
Installation Method
Dual mounting options: SAE standard flange mounting, optional foot bracket mounting for selected models.
Preferred installation: horizontal mounting to maintain proper oil level inside pump housing. Shaft-up vertical mounting is available with specified drain port configuration.
Drive connection: splined shaft or straight shaft, connect via flexible coupling.
Oil ports: side or rear port layout, inch thread or metric thread with O-ring seal.
Drain line requirement: full size drain pipe routed directly to tank, housing pressure limited below 0.35~0.7 bar.
Pre-commissioning: fill oil into pump housing and bleed air before startup to avoid cavitation damage.
Application Range
Injection molding machines, metal forming equipment, mining machinery, hydraulic presses, conveyor systems, oil & gas auxiliary units, test benches and general heavy-duty industrial hydraulic systems.
