SPECK VU - VH - VZ Liquid Ring Vacuum Pumps

SPECK VU, VH, VZ Liquid Ring Vacuum Pumps:

Proven technology for a wide range of applications.

SPECK VU, VH, and VZ series liquid ring vacuum pumps provide suction and compression for various gases and vapors, utilizing natural cooling from the service liquid. This technology keeps operating temperatures low, enhances mechanical reliability, and ensures an excellent equipment service life.

The range is available in several configurations to precisely meet different vacuum level requirements:

VU Series : single-stage pumps designed for rough vacuum with minimum pressures between 120 and 150 mbar absolute.
VU-351 / VU-451 Series : single-stage versions equipped with valves to achieve high vacuum down to 33 mbar absolute.
VH Series : two-stage pumps without valves, offering high performance down to 33 mbar absolute.
VZ Series : low-noise, two-stage pumps, also available with magnetic coupling and connection dimensions identical to the VH series.

Variantes	Particularités
Construction simple étage	Technologie adaptée au vide grossier offrant une conception robuste, un fonctionnement fiable et une maintenance simplifiée.
Construction double étage	Permet d'atteindre un vide plus poussé, jusqu'à 33 mbar absolus, avec une excellente stabilité de fonctionnement.
Version avec clapets	Présente sur certaines pompes de la gamme afin d'améliorer les performances à basse pression et d'optimiser le niveau de vide obtenu.
Version sans clapets	Conception simple limitant le nombre de composants mécaniques et favorisant la fiabilité en fonctionnement continu.
Version avec accouplement magnétique	Disponible sur certaines pompes de la série VZ pour garantir une étanchéité renforcée et réduire les risques de fuite de fluide ou de gaz.
Exécutions en matériaux spécifiques	Différentes combinaisons de fonte, acier inoxydable ou matériaux non ferreux sont proposées afin de s'adapter aux caractéristiques des fluides véhiculés et aux environnements corrosifs.
