Features
Titanium and Titanium Alloy Pumps
| Specification | Centrifugal Pump | Positive Displacement Pump | Submersible Pump |
| Operation Principle | Uses rotational kinetic energy to move fluid | Traps a fixed amount of fluid and displaces it | Fully submerged in the fluid it pumps |
| Common Types | Single-stage, multi-stage, axial, radial | Gear, piston, diaphragm, screw, vane | Well pumps, sewage pumps, slurry pumps |
| Flow Rate | High, continuous flow | Precise, low to medium flow | Medium to high, depending on application |
| Pressure | Variable, generally lower than PD pumps | High pressure, suitable for thick and viscous fluids | Variable, can handle significant head pressure |
| Viscosity Handling | Low to medium viscosity fluids | High viscosity fluids | Typically low to medium viscosity fluids |
| Efficiency | High efficiency at optimal flow rates | High efficiency across a range of viscosities | High efficiency in submerged conditions |
| Self-Priming | Generally not self-priming, requires priming | Typically self-priming | Not applicable, always submerged |
| Installation | Above fluid level, needs priming | Can be installed above or below fluid level | Installed below fluid level |
| Maintenance | Moderate, easy access to components | Generally higher maintenance | Low maintenance due to submerged design |
| Applications | Water supply, HVAC, irrigation, chemical transfer | Oil and gas, chemical processing, food and beverage | Wastewater management, dewatering, mining |
| Material Options | Cast iron, stainless steel, titanium, composites | Stainless steel, titanium, various alloys | Cast iron, stainless steel, titanium, plastic |
| Temperature Range | Wide range, depending on materials used | Wide range, highly adaptable | Moderate to high, depending on design |
| Cost | Generally lower initial cost | Higher initial cost | Variable, typically moderate |
| Advantages | Simple design, easy to operate and maintain | Accurate flow rate, handles viscous fluids well | Can operate in flooded environments, reliable |
| Disadvantages | Not suitable for high viscosity fluids, requires priming | More complex, can be expensive, higher maintenance | Limited to submerged applications |
| Key Performance Metric | Flow rate (GPM, LPM) | Volume per revolution (cc/rev, L/rev) | Head height, flow rate (GPM, LPM) |
| Features | |
| Corrosion Resistance | High resistance to acids, chlorides, and other corrosive chemicals |
| Durability | Long service life with minimal maintenance |
| Versatility | Suitable for a wide range of fluids and operational conditions |
| Ease of Maintenance | Designed for easy disassembly and reassembly for maintenance |
