P Series
Thanks to magnetic coupling, these pumps operate contact-free and wear-free. This is ideal for toxic, environmentally hazardous or aggressive media. They are designed for high pressures and can be controlled very precisely.
The P series can pump media up to a temperature of 60 °C. Under the designation P-EX, we also offer an ATEX-certified version for use in ATEX zone 2.
Special features of the P Series
- Very precise pump control due to linear pump curve
- Hermetically sealed and absolutely leak-free (no mechanical seal)
- Particularly suited for toxic, environmentally harmful and corrosive media
- Very suitable for pumping low-boiling liquids
Features
- Hermetically sealed and absolutely leak-free (no mechanical seal)
- Powerful magnetic drive with neodymium magnets
- Practically maintenance-free in normal operation due to extra-large slide bearings
- Runs in partial dry run conditions due to large diameter PTFE slide bearings – design without impeller shaft Features
- All wet parts made of high-quality, corrosion-resistant plastics (PVDF or PP)
- Threaded connections (ISO 228-1) as standard
- Universally applicable, low-noise and compact close-coupled design
- Approved for use in explosive atmospheres ATEX zones 2
- Corrosion-resistant paint finish
- All stainless steel screws in 1.4571 (316Ti)
- FDA-certified materials (PVDF versions)
Fields of applications
Delivery of acids, bases, lye or other corrosive, harmful or toxic liquids in such applications, where even small leakages are not acceptable and a hermetically sealed pump is required. Delivery of highly pure and sensitive liquids, where contamination must absolutely be avoided.
For example in the following applications:
- Plating and surface coating
- Semiconductor technology and solar cell production
- PCB and electronics manufacturing
- Wastewater and fresh water treatment
- Laboratory equipment and medical technology
- Emission controls and gas scrubbers
- Battery production and energy storage
- High-purity applications, demineralized water, ultrapure water
