3. Key Features & Benefits
-
Durable Construction: Three-piece cast iron housing provides excellent structural strength and distribution flexibility, enabling resistance to harsh operating environments and corrosive media.
-
Enhanced Efficiency: Balanced thrust plates minimize friction and internal leakage, while precision journal bearings extend service life and maintain high volumetric efficiency even in high-temperature and low-viscosity conditions.
-
Integrated Valve Capabilities: Supports extensive integrated valve options, including load sense flow control, relief valves with anti-cavitation check, priority flow control, and solenoid unloaded relief valves.
-
Flexible Configuration: Available in single, tandem, and multiple-section designs, with cross-frame add-a-pump options. Standardized SAE, ISO, and DIN mounting flanges, shafts, and port connections ensure easy integration.
-
Broad Compatibility: Multiple port types (flange, straight threaded) and locations (side ports, rear ports) with SAE, ISO, NPT, BSPP, and ODT connections adapt to diverse system requirements.
