Working Conditions
- Temperature Range: Liquid temperature ≤80°C (up to 120°C), ambient temperature generally ≤40°C
- Maximum Working Pressure (inlet + pump pressure) :
1.0 MPa(G) when H9 ≤ 75m
1.6 MPa(G) when H9 > 75m
- Special configurations available up to 1.6 MPa(G) or 2.5 MPa(G) respectively
- Seal Water Supply: Not required if inlet pressure ≥ 0.03 MPa(G)
Features & Structure Design
Impeller
- Features a double-suction design that minimizes axial force to the lowest level.
- Equipped with an optimal hydraulic model refined through CAD optimization, ensuring excellent performance.
- One pump casing can accommodate both the original impeller and modified versions, allowing adaptation to various operating conditions and improving efficiency.
Pump Casing
- Adopts a double-volute structure to reduce radial forces, resulting in lower bearing loads and extended service life.
- Features a self-aligning pump cover for easy installation.
- The relative position of the motor, pump, and piping can be customized based on site requirements.
- Inlet is free of filtration chambers, ensuring smooth operation and low energy loss.
Bearings
- Utilizes grease-lubricated rolling bearings that are easy to maintain, with enlarged bearing size for longer life.
- The rear-end bearing uses a sleeve-and-key assembly, ensuring secure fixation and convenient disassembly.
Shaft
- Features a thicker shaft with high rigidity, ensuring stable operation and innovative design.
- Short-term reverse rotation causes no damage, and direction changes are convenient.
- The shaft is fully sealed, preventing contact with liquid and eliminating thread corrosion.
- All parts maintain precise assembly dimensions, eliminating the need for on-site adjustments during pump assembly.
Baseplate
- Available with a welded baseplate upon request, offering high impact resistance, good toughness, and durability while remaining lightweight.
Shaft Sealing
- Equipped with a high-quality mechanical seal that ensures zero leakage; the seal sleeve is made of stainless steel to prevent rust and simplify maintenance.
- Offers non-asbestos soft packing that meets environmental standards.
- Features an injection-type soft packing with online maintenance capability, allowing servicing without shutdown, avoiding costly downtime, and minimizing friction losses—all while ensuring no leakage.
