LKH Prime
Para una mayor eficiencia de la bomba y un importante ahorro energético, elija la bomba autocebante Alfa Laval LKH Prime. Su diseño avanzado, con tecnología de bomba de tornillo de aire, facilita tanto las tareas de limpieza in situ (CIP) con aire arrastrado como el bombeo de fluidos de proceso. Esto reduce la inversión de capital. Al igual que la gama de bombas Alfa Laval LKH, la LKH Prime cumple con los requisitos más exigentes de las industrias alimentaria, láctea, de bebidas
La alta eficiencia de la bomba y el bajo nivel de ruido optimizan el vaciado de depósitos y las aplicaciones de retorno CIP
- Bajo riesgo de contaminación del proceso: diseño higiénico, materiales conformes con la FDA y elastómeros de compresión predefinidos de clase VI
- Mejora el rendimiento y la sostenibilidad: el uso de energía y productos de limpieza, junto con el diseño hidráulico, reduce los costes energéticos
- Máximo tiempo de actividad y menores costes de mantenimiento: diseño mecánico robusto y facilidad de mantenimiento gracias a las juntas modulares
- Menor inversión de capital: está diseñado para tareas de limpieza en proceso (CIP) en las que hay aire arrastrado, pero también puede bombear
- Funcionamiento silencioso en comparación con otras tecnologías, lo que garantiza un entorno de trabajo seguro para los operarios de la planta
La bomba autocebante Alfa Laval LKH Prime, que forma parte de la gama de bombas LKH, combina una avanzada tecnología de tornillo de aire con una geometría optimizada del impulsor y la carcasa para ofrecer un funcionamiento silencioso y fiable, una mayor eficiencia energética y una menor huella de carbono. Su calidad y rendimiento superiores mejoran la productividad operativa. Fabricado a partir de una barra maciza sin soldaduras para lograr un acabado liso, el tornillo de aire cumple con estrictas normas y requisitos higiénicos. La bomba autocebante cuenta con un sello mecánico sin sustancias lixiviables, diseñado para aplicaciones de retorno CIP que contienen una mezcla de aire/gas y líquido. La larga vida útil del sello y la ausencia de contaminación aumentan la productividad y el rendimiento.
How does the LKH Prime centrifugal pump work
Construction
Alfa Laval LKH Prime is a self-priming centrifugal pump based on air-screw technology. It offers excellent operational efficiency, reducing energy consumption. The pump achieves capacities of up to 110 m3/hr and pressures of up to 115 m head.
The self-priming pump shares many common components with the Alfa Laval LKH pump range including the impeller, which can be trimmed to optimize pump performance according to its application. Dedicated components include the airscrew, casing, re-circulation pipe and cover.
Operating principle
To understand how does a self-priming pump work, it's essential to know that it uses a combination of air and water to create a vacuum, allowing it to lift fluid from a lower level. On applications where the pumped media contains a mixture of air and liquid in the suction line, air-screw rotation causes the formation of a continuous liquid ring within the canister.
Due to the eccentric position of the canister relative to the air-screw, an air chamber forms between the liquid ring and the air-screw, as shown, which separates into air pockets between the air-screw vanes.
The continuous rotation of the air-screw forces air pockets through the canister into the suction stage of the impeller which are then pumped out via the discharge.
Liquid is returned from the discharge via the re-circulation pipe into the canister to ensure the liquid ring is maintained at all times.
When there is no air present, the canister and recirculation loop have no function and are fully filled with liquid. The liquid passes through the canister into the suction stage of the impeller, allowing the pump to act as a traditional centrifugal pump.
Self-priming pump configuration options
- Impeller with reduced diameter
- Motor with increased safety/flame proof motor
- Double mechanical shaft seal
- Product wetted surface finish Ra ≤ 0.8 µm
- Product wetted elastomers in EPDM, nitrile (NBR) or fluorinated rubber (FPM)
- Silicon carbide rotating seal ring
- ½” tri-clamp drain connections (two connections)
