Tobee® self-balancing multistage pumps typically consist of two or more impellers mounted on a common shaft. Each impeller, known as a stage, adds energy to the fluid, increasing the overall pressure head. This arrangement allows the pump to generate higher pressures compared to a single-stage pump.
Tobee® Self-balancing Multistage Pump is a horizontal single suction multistage centrifugal pump designed by API610 standard, with advantages of high efficiency, wide performance, steady and safe operation, low noise, long work life, easy installation, etc. It can transport the medium with solid particles (the particle size should be less than a quarter of the impeller channel), and the pump can use different materials, and seal types, adding a cooling system for delivering clean water, hot water, boiler feed water, corrosive liquids, oils, and abrasive medium etc.
Self-balancing Multistage PumpDesign Features:
• With symmetrically arranged impeller rotor components, axial forces generated by all levels of symmetrical impeller forces offset each other, and automatic balancing of huge axial thrust within the pump cavity can be realized without the balanced disc structure.
• Unique throttling and pressure reduction devices, odd-level balancing device
• Using an advanced hydraulic model, independent R&D energy-efficient products, Good centering of the impeller and guide vane channel, and efficiency will not significantly drop as balancing disc wears and rotor components move forward. No leakage of balancing water reduces loss of volume and improves pump efficiency and pump efficiency is on average 2-5% higher than normal pumps
• By canceling the easy-failing balancing disc, pump reliability is greatly improved, and maintenance frequency and maintenance cost are reduced
• By adopting precision casting and unique throttling and pressure-reducing devices for auxiliary support pump vibration and noise are greatly reduced and service life is prolonged
• Excellent hydraulic model and design, unique first stage double suction impeller, forging casting, reliable anti-abrasive materials make sure the pump with excellent NPSH, pump works steadily, there is no noise, and users do not need to add a preposition pump or increase the height of the inlet chest
• No axial clearances when the pump is working and stops.
• It can change the mechanical seal, and bearing without disassembling the inlet/outlet pipes.
• Forging casting spare parts can save the maintenance cost
• No balance device makes the pump more wider application.
Tobee® Self-balancing multistage pumps are specifically designed for high-pressure applications where a significant pressure boost is required. They are commonly used in industrial processes such as boiler feed water, reverse osmosis systems, water supply, irrigation, and high-pressure cleaning systems.
