Rugid cast iron single stage
Our compact single pumps provide high power density, relief valves, and optional process flow diagrams (PFDs) on their covers.
Features and benefits
- High-strength cast iron construction allows consistently efficient performance
- Custom-engineered shaft bearings and dual pressure-balanced thrust plates optimize internal bearing lubrication, allowing for high starting torque and long life with fluid viscosity as low as 8 mm²/sec [52 SUS]
- Compact three-piece ductile iron construction with bearings located in the front flange and rear cover minimizes overall package length and increases radial load-carrying capability
- Pressure-balanced thrust plates provide improved efficiency at extreme pressures and temperatures
- High-temperature Viton® seals are well suited for today’s hotter-running machines
- Located in the front flange, high-quality steel-backed bronze bearings provide maximum pressure handling capacity, allowing extended radial loading without an external roller bearing
- Available with side or rear ports, SAE A or B flange, an a variety of shaft options
Applications
- Agriculture
- Construction
