Espira 02 - Peripheral mixers in special application-specific design have a comparable design and the same constructive characteristics as standard peripheral mixers. They are also magnetically coupled and hermetically sealed. However, material selection and pump head design are in special design adapted to the special mixing process.
In a simple design the pump head has a heating chamber, to which a heat transfer circuit with a thermostat or a superheated steam is connected.
In an expanded version, in addition to the heating of the pump head, the heating of the split pot is included in the heat transfer circuit. In this case, the mixing pump is designed in a double split pot design, especially when low melting point fluids in the flow-reduced split pot region carry the risk of crystallization.
In special process-related requirements, the pump head can also be electrically heated to maintain a required process temperature or for a necessary preheating of the pump mixing head in the start-up phase of the process.
In specific cases, we ask for consultation.
In individual cases, peripheral mixers can be designed for fluid temperatures up to 450 ° C.
In a simple design the pump head has a cooling chamber, to which a coolant transfer circuit with a cryostat or a cold water circuit is connected.
In an expanded version, in addition to the cooling of the pump head, the cooling of the split pot is included in the coolant transfer circuit. In this case, the pump is carried out in a double-gap pot design, especially when low boiling point fluids are to be mixed, exothermic mixing operations result in additional heat generation, and at the same time heat generation through the magnetic drive in the split pot region is to be limited or avoided.
In individual cases, peripheral mixers can be designed for system pressures up to 750 bar.
The pressure build-up between pump input and output, means the so-called dp, is independent of the system pressure of the mixer. The pressure difference between pump input and output is based exclusively on the assigned characteristic of the mixing pump.
They are therefore particularly suitable for simultaneously mixing fluids and gases during the delivery process and for mixing gases in finely dispersed form in a liquid.
With special impeller geometries, gas fractions up to 50% by volume can be mixed into the fluid and transported along in individual cases.
Please note that as a special pump manufacturer, we can not provide Atex certification on our pumps. However, we provide Atex compliance with the delivery of each pump.
Frequency converters are usually outsourced from the hazardous location. If a solution with a permanently installed frequency converter is required in individual cases, we ask for consultation in order to be able to solve your application precisely.
