Dosing Pumps
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
Diaphragm pumps
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
Piston Pumps
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
Dosing Systems
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.
Polymer Stations
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.
- PolyLine® Swing
Polymer preparation station as a pendulum system.
- PolyLine® Double
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.
Further Pumps
Feeding Pumps
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.
