Small quantity mixers Espira 02

Espira 02 - Small quantity mixing pumps are magnetically coupled peripheral pumps designed for demanding mixing, dilution and homogenisation requirements in the laboratory, process development and small scale industries.


Essentially, Espira 02 - small mixers have the same constructive design as a peripheral pump with delivery channel, interrupter, the typical peripheral impeller with application-specific design of the peripheral delivery cells and the drive motor with magnetic coupling.

The pump head is additionally equipped with one or more fluid connections to enter 1-3 mixing components directly into the pump head.

During the rotation of the impeller there is a rapid pressure increase in the peripheral delivery cells, with a pressure equalization via the impeller and an intensive mixing with the fluid in the delivery channel. This characteristic impulse exchange for peripheral mixers is the basis for an intensive mixing and homogenisation process within the pump head and during the delivery process.

Espira 02 mixing pumps are therefore an effective and economical alternative to stirred tanks, rotor-stator mixers, injectors and static mixers for many processes. Their tolerance to solid or gas fractions also offers alternatives to microchannel-structured mixing units.

Espira small mixers are always manufactured by Fink Chem+Tec in magnetically coupled design. They are therefore hermetically sealed and meet the environmental requirements according to TA-Luft (technical instructions for keeping the air clean).

Material features:

Espira 02 - Peripheral wheel pumps are designed primarily for harsh operating conditions, aggressive fluid properties and high gas fractions in the fluid.

Various stainless steel, Hastelloy, ceramic and tungsten carbide (carbide) or PTFE linings are used for the pump housing. For static sealing O-rings made of FKM, FFKM (Kalrez) or high-temperature resistant seals are selected.

Fluid connections:

Depending on the application and integration of the pumps into the process, the fluid connections use stainless steel or PTFE / PFA cutting ring fittings, flange connections or high pressure fittings.

Operating conditions:

Espira E02 - small mixers can be used for simple mixing tasks during the production process and even for the most demanding chemical applications. They can be configured for process temperatures up to 450 ° C, system pressures up to 700 bar and atex-compliant Ex-designs.

They are used in research, process development, and small scale production for delivery, mixing, or diluting aggressive acids, alkalis, solvents, or mixing and emulsifying difficult-to-mix fluids, even under high pressure conditions and for high process temperatures.

With their tolerance to solid or gas fractions, mixing processes with μm-solid components or the mixing in of gases in liquids during the delivery process are also suitable.

Due to their hermetically sealed, magnetically coupled design, peripheral mixers ensure emission-free handling of aggressive fluids and environmentally hazardous substances and meet the requirements of TA-Luft (technical instructions for keeping the air clean).

Espira Lab

EspiraLab – Small-Mixers and Small-Reactors are based on the delivery principle of peripheral pumps with their intensive turbulence and mixing during the delivery process. The pump head is additionally equipped with one or more fluid connections to enter 1-3 mixing or reaction components directly into the pump head.

EspiraLab EL-02 Small-Mixers and Small-Reactors are particularly adapted to the conditions of laboratory application, process development or small scale production optimization.
They are designed in a compact housing and with integrated speed control. A separate frequency converter and its installation is not required. This saves time, space, installation effort and investment costs.
Operation can be carried out either directly via the illuminated touch panel on the pump or via external interface communication.

For external control, a 4-20 mA interface and a digital RS232 interface are available. The setup button on the user interface can be used to select between internal and external operation.
EspiraLab – Small-Mixers and -Reactors are therefore compact, speed-controllable and automation-capable system solutions for diverse mixing and reaction processes in the laboratory, in process development and for device applications.
