Peripheral wheel pumps Flujo 01 in
application-specific design

Flujo F01 – Peripheral wheel pumps in special application-specific design have a comparable design and the same constructive characteristics as standard peripheral pumps. They are also magnetically coupled and hermetically sealed. However, material selection and pump head design are in special design adapted to the special delivery process.

Heatable 300 ° C:

Heatable peripheral pumps F01 are used if high process temperatures are required due to the process or if delivery processes with solidification-critical melts and the risk of crystallization are to be realized.

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 peripheral 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 head in the start-up phase of the process.

In specific cases, we ask for consultation.

High temperature design:

High temperature peripheral pumps Flujo 01 are specially designed for delivery processes with high process temperatures. They are always calculated and designed for the specific application.

In terms of design, the extremely different thermal expansion coefficients of the materials used and the temperature dependence of the drive magnets must be taken into account. Heatable pump heads, separately heatable bearing housings, decoupled and partly coolable drive lanterns, separate split pot rinses or even special operating modes make the design of these mixing pumps a very complex task.

In individual cases, peripheral wheel pumps can be designed for fluid temperatures up to 450 ° C.

Coolable pump heads:

Coolable Flujo 01 pumps are mainly used when process-related required fluid temperatures to keep constant or outgassing effects (and cavitations) are to be avoided during the mixing process.

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. The pump is designed in a double-gap pot design. This design is useful when pumping low boiling point fluids and at the same time limiting or avoiding heat buildup through the magnetic pump drive in the can.

Corrosion-resistant equipment:

Corrosion-resistant F01 peripheral pumps are used when pumping the most aggressive fluids requires maximum chemical resistance. For this purpose, the stainless steel housing of the peripheral pump and the flange connections are equipped with full PTFE inliners. The pump rotor and the split pot are also lined with PTFE or manufactured in a PTFE carbon version. The pump shaft consists of a SiC or WoC ceramic.

Process pressures 750 bar:

High pressure peripheral pumps Flujo 01are especially in demand for delivery processes with high system pressures. They are always calculated and designed for the specific application. Above all, the split pot must comply with the requirements of the Pressure Vessel Ordinance, are not allowed to restrict the transmission of the magnetic drive forces and keep the heat generation due to eddy current losses low.

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 pump. The pressure difference between pump input and output is based exclusively on the assigned characteristic of the mixing pump.

Multi-phase pump:

Flujo 01 multi-phase pumps utilize the ability of the peripheralpump principle to deliver high levels of gas in the fluid.
They are therefore particularly suitable for conveying low-boiling-point fluids, for discharge processes in distillation plants, for delivering liquids with dissolved gas fractions or liquid / gas mixtures.

In water / wastewater treatment, they are used as so-called multiphase pumps in fumigation flotation or denitrification.

With special impeller geometries gas fractions of up to 50% by volume can be conveyed in the fluid in individual cases.

Adapted speed control:

Speed-controlled Flujo peripheral pumps can be networked with external frequency converters for variable, speed-adapted delivery, or equipped with a frequency converter mounted on the drive motor.

The functionality of the frequency inverter can be used to control the start-up of the pump (soft start), the setting of the specific operating point, process-dependent flow rates or even energy-efficient operation.

Atex compliant design:

Atex-compliant Flujo 01 peripheral pumps are designed for use in Zone 1 and 2 potentially explosive atmospheres.

All pump-relevant components and the overall design of an explosion-proof pump are designed taking into account the respective Ex classification of the production facility according to Atex regulations. Ex-certified engines with required temperature monitoring are installed by market-leading engine suppliers.

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.

Inline peripheral pumps:

Flujo 01 - Inline peripheral impeller pumps are designed especially with dimensioning of the delivery channel with interrupter, the impeller and the flange connections so that they can be integrated "inline" into the conveying process. The flange connections of the in-line pump can be integrated into a vertical or horizontal piping installation.
