Introduction
Are you looking for a pump that is reliable, safe, cost-effective, and suitable to transfer highly corrosive fluids and wastewater? Then the vertical Polypropylene (PP) and PVDF immersible pumps are the right solutions.
We know that the pump works on the basic principle of pushing the liquid to the surface by converting rotary energy to kinetic energy and finally into pressure energy.
An immersible pump is different from a submersible pump as it has to transfer highly corrosive liquid, and due to it, the motor is mounted above the tank with a shaft extended to the pump end at the bottom of the tank.
The immersible pumps are a cost-effective and flood proof solution, especially suitable for dry environments. They are designed especially for corrosive and aggressive situations and applications such as sump emptying, recirculation, and transfer.
They are made from different materials ranging from 316 stainless steel to engineered plastics such as polypropylene (PP) and PVDF that allow indefinite run-dry capabilities.
So let us understand the features and applications of vertical PP and PVDF immersible pumps.
Working
Immersible pumps are designed using Totally enclosed non-ventilated enclosures(TENV) in smaller frames, and Totally enclosed blower cooled(TEBC) enclosures on larger frames. A special sealing system allows continuous operation submerged underwater at a maximum depth of 9 feet of water.
The extended shaft is encased in a Polypropylene/PVDF/PTFE tube and connected to the impeller at the opposite end. All the parts in contact with the liquid are made up of polypropylene or PVDF material to avoid corrosion. The impeller is designed to keep the corrosive liquid out without any oil seal configuration.
The impeller ensures that the liquid does not travel to the motor side. The overflow passes the annular space between the shaft and the column pipe. The excess liquid flows back to the tank through the drain holes in the column pipe. Thus the vertical PP and PVDF immersible pumps are the most cost-effective solution to maintain, fix and purchase and operate.
Features
- All the wetted parts of the pump are made up of Polypropylene (PP) or PVDF or PTFE material.
- There is no intermediate bearing, so absolutely safe to run dry.
- It is abrasion-free, thus suitable for high purity applications.
- It has an energy-efficient design.
- These pumps have low maintenance, hence the cost-effective operation
- The pump parts made of PVDF material are carbon fiber reinforced, which reduces thermal expansion at higher temperatures and ensures high energy efficiency.
- It has a reinforced motor ball bearing and extended shaft for stability and durability.
Applications
- Scrubber systems such as gas and fume scrubbers, exhaust scrubber for ships
- Filtration of liquids
- Using in coating plants
- Used for operation in water treatment plants
- Purging applications
- Electroplating equipment
- Disinfection systems
- Effluent treatment
- Recirculation process
- Transfer of Acids
- Handling corrosive liquids
Conclusion
The vertical polypropylene and PVDF immersible pumps thus stand the test of time that offers the best performance constantly throughout the pump's life, minimizing the operation and maintenance cost while keeping your process running efficiently.
Our immersible pumps can run-dry indefinitely with the benefits of impellers that prevent the liquid from backing up the pump shaft.
Our vertical PP and PVDF immersible pumps are suitable for all types of applications, such as tank emptying, recirculation, effluent treatment, and many other corrosive applications. Hence, every PP and PVDF vertical immersible pump can be tailored as per your requirements regarding column length, mounting plate, or outlet position.
