Our PP & PVDF Immersion Centrifugal Pumps, forming part of our CTV Vertical Centrifugal Pump range, is a reliable solution tailored for fluid transfer and circulation within corrosive Chemical applications. These pumps find many uses in Surface Treatment baths, and circulating through filters and nozzle ramps. The PP variant excels at handling chemicals at temperatures up to 70°C, while the PVDF variant offers higher temperature tolerances at up to 100°C. Once installed, these pumps have near-zero maintenance requirements, boasting a sealless design and ensuring leak-free, safe dry running. Capable of handling liquids with particles up to 6mm, these pumps offer customisation options, including Suction Extensions, Strainers, optional discharge connections, and left-hand threads on the pump cover, enabling tailored configurations to meet specific operational needs.

Overview
Features & Benefits
Specifications
Variations
The PP and PVDF Immersion Centrifugal Pumps are specifically designed to handle highly corrosive chemicals at higher temperatures.
- PP (polypropylene) Immersion Centrifugal Pumps are ideal for handling various chemicals, including pickling baths and acid degreasing solutions, at temperatures up to 70°C
- PVDF (polyvinylidene fluoride) Immersion Centrifugal Pumps offer superior chemical and mechanical resistance at temperatures up to 100°C, making them ideal for hot acids, such as hot hydrofluoric acid
What makes the PP and PVDF Immersion Centrifugal Pumps great?
- Corrosion resistance: constructed with PP (polypropylene) and PVDF (polyvinylidene fluoride), these pumps offer excellent corrosion resistance
- Temperature capabilities: these pumps can maintain performance in challenging conditions thanks to their ability to handle hot fluids up to 70°C for the PP variant and 100°C for the PVDF variant
- Simple design: the simple yet reliable design of these pumps allows for easy maintenance and and troubleshooting, resulting in minimal downtime and reduced maintenance costs
- Sealless: features a sealless design which minimises the risk of leaks
- Operational safety: designed to operate without leakage and can handle dry running conditions
- Particle handling: these pumps can handle liquids with particles up to 6mm ø
- Customisable: there are various options and special executions available for these pumps, including suction extensions, strainers, optional discharge connections and left hand threads on the pump cover (for pumping viscous liquids)

Variations and special executions available:
- Suction Extension (PP, PVDF, SS): a great solution where there’s a need to empty a tank or sump from a lower level than the immersion depth of the pump. A 500mm and 1000mm extension pipe is available as standard
- Strainer (PP, PVDF, SS): A suction strainer is a great option where the liquid is dirty or contains solids
- Optional Discharge Connection (PP, PVDF, SS): The CTV pump can be delivered with optional connections on the discharge side. Flanges following ANSI and DIN standard are available. Loose or welded flange
- Left-hand Thread on Pump Cover (PP, PVDF): To avoid unintentional unscrewing of your pump cover (this is recommended when pumping viscous liquids), there is the option of a left-hand thread on the pump cover. The thread differs from that of the standard option by means of a cut on the socket
