DESCRIPTION

The ALLWEILER three screw pumps are used to pump oils or other lubricating liquids, non-lubricating liquids, or liquids with poor lubricating properties.

The pumps are also characterized by very high efficiency and reliability. The liquid is moved continuously, without pulsation, turbulence, crushing or loss of lubrication. For overload protection a built-in-pressure relief valve is available (optional).

The three screws have special shapes that create sealed chambers, the contents of which are continuously moved in a axial direction from the suction side to the discharge (high pressure) side as the screws rotate.

Contactless and non-slip torque transfer greatly extends maintenance intervals and significantly increases the MTBF (Mean Time Between Failures).

Single-channel, self-priming, with low noise level and very well suited for use with variable speed drives (frequency converters).

A long service life due to hardened and ground screws and hydraulically driven idler spindles that are not subject to mechanical wear.

Low maintenance due to the internal bearing being lubricated by pumped liquid or external bearing grease lubricated.

Easy to maintain with a complete insert unit that is removable, therefore the pump casing remains in the piping.
