T Series

These durable and chemically resistant vertical plastic immersion pumps work in the standard version without seals and up to 95 °C. Optionally also available with shaft seal as vapour barrier.

The T series features a vertical shaft extension that directly drives the impeller. The rotating shaft runs completely contact- and abrasion-free inside the housing (“cantilever” design). This design concept eliminates the need for shaft seals and additional bearings

Special features of the T Series

Absolutely dry run safe because of contact-free shaft and impeller rotation
No abrasion into the fluid, therefore well-suited for high-purity applications
Maintenance-free operation as no wearing parts such as slide bearings or mechanical seals

Features

Absolutely dry run safe because of contact-free shaft and impeller rotation
Maintenance-free operation as no wearing parts such as slide bearings or mechanical seals
Available with extension tubes in different lengths to individually adjust the immersion depth
Available with inlet strainer to prevent rough dirt and objects from entering the pump housing
All wetted parts made of high-quality, corrosion-resistant plastics (PVDF or PP)
Threaded connections (ISO 228-1) as standard
Optionally available with flange connections (from size 130)
Universally applicable, low-noise and compact close-coupled design
Corrosion resistant motor finish

Fields of application

Installation in return vessels, tank tops, container lids, pump sumps, etc. Delivery of acids, bases, lye or other corrosive liquids. Useful in applications, where dry running of the pump cannot be prevented at times.

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
