- Sealless side-channel (peripheral) pump with PTFE/PFA lining in close-coupled configuration — eliminates shaft seals and leaks
- Hermetically sealed containment shell, resistant to aggressive and hazardous fluids — insensitive to cavitation
- PTFE impeller mounted on ceramic shaft, supported by silicon carbide bearings — ensures dry-run tolerance and smooth operation
- Permanent-magnet coupling with carbon-fibre/PTFE or zirconium oxide shell — no eddy-current losses
- Capable of handling up to 30% gas content in the fluid

The GEKOBLOCK PM Series represents a cutting-edge solution for transferring aggressive, toxic, volatile, and low-boiling liquids in industries where leak prevention, chemical resistance, and operational safety are top priorities. These pumps operate using magnetically coupled drive systems, which eliminate the need for mechanical seals – the most common source of leakage in traditional centrifugal pumps. As a result, the GEKOBLOCK PM Series delivers hermetically sealed performance, making it ideal for critical processes in the chemical, pharmaceutical, semiconductor, and petrochemical industries.
Built with PTFE or PFA linings, ceramic shafts, and silicon carbide bearings, the pump head is designed to resist high corrosion, cavitation, and dry-run conditions. The side-channel design enables it to prime itself under challenging suction conditions and even operate with gas-laden liquids up to 30%, where conventional centrifugal pumps would fail.
Thanks to the modular, close-coupled design, GEKOBLOCK PM pumps are compact, easy to maintain, and adaptable to confined spaces. The pumps are available in several sizes and configurations, providing a range of flow rates and heads for high-pressure, low-flow dosing and metering tasks. This makes them especially suitable for transferring concentrated acids, solvents, cooling liquids, and aggressive cleaning agents at temperatures up to 150°C and pressures up to 16 bar.
Whether you need safe transfer of corrosive chemicals or high reliability in dosing applications, the GEKOBLOCK PM series is a powerful, efficient, and future-proof pumping solution.
