Brevini Gear Pump Product Catalog
Overview
Brevini (Brevini Hydraulics), a renowned Italian manufacturer of hydraulic components, specializes in high-performance gear pumps designed for heavy-duty industrial, mobile, and marine hydraulic applications. Its product range mainly coversHigh-Pressure Helical Gear Pumps (PHC1 Series) and Fixed-Displacement External Gear Pumps (OT Series), including OT100, OT200, and OT300 subgroups. All Brevini gear pumps feature robust cast iron construction, axial clearance compensation, low noise operation, and high reliability, widely applied in construction machinery, industrial hydraulic stations, marine equipment, and metallurgical systems.
1. High-Pressure Helical Gear Pumps (PHC1 Series)
The PHC1 series is Brevini’s high-pressure helical gear pump, characterized by its compact structure, high efficiency, and long service life. It adopts a helical gear design to reduce noise and pressure pulsation, with axial clearance compensation to minimize internal leakage, making it ideal for heavy-duty hydraulic systems and high-pressure working conditions.
