For decades the proven sera delivery program has had an excellent reputation for its high-quality and long-lived products in the area of dosing units. With sera dosing pumps, we can dose nearly all flowing media, even with aggressive, abrasive, odorous, radioactive, inflammable, viscous or toxic properties – reliably and safely.
Solenoid diaphragm pumps
The solenoid diaphragm pumps of the 2 series are available with extensive (C204.1) control electronics. For special dosing problems and to meet nearly all of our customers‘ needs, we offer individual solutions, e.g.:
- Multi function valves
- Completely available with dosing kits («plug & dose»)
- Design with Profibus DP-Interface
Performance range from 0,4 l/h to 35 l/h, counter pressures up to max. 10 bar
Stepper motor pumps
The new sera dosing pump iSTEP combines an intelligent drive concept with the accuracy of a diaphragm pump.
It sets new standards in terms of reproducibility and reliability.
Performance range up to 50 l/h, counter pressures up to max. 10 bar
sera diaphragm pumps are leak-free oscillating displacement pumps designed for the dosing of volumes up to 1450 l/h.
Performance range from 0,4 l/h to 1450 l/h, counter pressures up to max. 10 bar
Piston diaphragm pumps
thenex offers sera piston diaphragm pumps that are leak-free oscillating displacement pumps. They are an ideal combination of the high supply pressure of a piston pump and the perfect leak-proof diaphragm pump.
Performance range from 7,5 l/h to 850 l/h, counter pressures up to max. 80 bar
thenex provides sera piston pumps which are versatilely applicable and despite its high pressure range extremely safe to operate. Due to low-wear components the maintenance of the piston pump is very low and therefore it convinces with accustomed quality and reliability.
Performance range from 8 l/h to 22 l/h, counter pressures up to 140 bar
Multi-layer diaphragm pumps
By using the multi-layer membrane, demanding safety dosing tasks can be realized.
Performance range from 11 l/h to 1200 l/h, counter pressures up to max. 20 bar
Standardized compact dosing systems
thenex offers sera Standardized Compact Dosing Systems which can be used everywhere; it is not a matter of highly complex and expensive dosing processes but only a controlled and precise quantity dosing of a liquid in one process or in a different medium. The completely modular design makes it possible with standardized components – like from a construction kit – to adapt the functions of the system to the individual dosing requirements.
Standardized polymer preparation unit sera PolyLine® is a series of easy, flexible, economical and efficient systems for the treatment of polymers.
- PolyLine® Flow
Polymer preparation station as a 3-chamber system.
Polymer preparation station as a pendulum system.
Polymer preparation station as a double-deck version.
Customized dosing systems
Individual dosing systems tailored to the customers’ needs.
Sodium hydroxide preparation system
thenex offers sera sodium hydroxide preparation systems, a cost-efficient system solution specifically aimed at industries with fluctuating, but large requirements of alkaline detergents or for countries where a continuous delivery is not secured.
KVV Dosing Systems
The KKV-Dosing system with automatic monitoring consists of single diaphragm pumps – made of high-quality materials and easy to maintain – combined with an automatic monitoring system.
Chlorine dioxide preparation and dosing units
Chlorine dioxide preparation and dosing units are dosing units for an efficient preparation and exact metering of 2% and 0,2% chlorine dioxide solutions.
Capacity up to 1.000 g ClO2/h at pressures up to 10 bar.
Air driven diaphragm pumps
Air driven diaphragm pumps are cost-effective, leakage free displacement pumps. They are driven by dry, non-lubricated compressed air.
Performance range from 5 l/h to 850 l/h, counter pressures up to max. 7 bar
FTi Centrifugal Pumps
thenex provides sera magnetically coupled centrifugal pumps for a wide range of applications.
