Flujo 01 - Multi-phase pumps are magnetically coupled peripheral pumps, designed for the delivery of fluids with a high gas content and for special applications of gas enrichment / mixing in liquids.
Due to the fluid dynamics a high degree of practical experience and know-how is linked for design of peripheral wheel pumps. The interaction of impeller, delivery channel and interrupter requires the targeted design of a multi-phase pump.
The impeller plays a crucial role in the design. The diameter, width, number and arrangement of the delivery cells must be determined precisely to the desired operating point. Impellers are designed with delivery cells on both sides up to the impeller hub. The targeted allocation of the delivery cells to the compensating drillings allows the delivery of fluids with a high gas content or a targeted gas entry.
Gas proportions up to 50% can be pumped with specially adapted pumps.
In water / wastewater treatment they are used as so-called multi-phase pumps in fumigation flotation or denitrification.
With special impeller geometries, gas proportions up to 50 vol% in the fluid can be deliverd in individual cases.
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.
Peripheral wheel pumps can be excellently controlled via a frequency converter in a wide range of delivery. For this reason, the use of a peripherally installed frequency converter is recommended in any case for reasons of practical handling and energy efficiency. In individual cases, integrated solutions can also be offered with a frequency converter installed on the pump.
