The invention relates to a cleaning rotor () having a longitudinal axis (L), a base part (), which extends concentric to the longitudinal axis (L), a head part () and a strut element () that extends between the base part and the head part. Said strut element () extends in a helical manner about the longitudinal axis (L). The invention is characterized in that at least one supporting part () is placed between the base part () and the head part () while extending parallel to the longitudinal axis (L). The strut element () is supported on the supporting part () and is concave over its length.

Cleaning rotor

A liquid aspirator, in particular for liquids containing solids such as sludge, has a receptacle into which liquid can be sucked in by an aspirator motor through a vacuum connector and from which the liquid can drain through a drainage. The receptacle has at least two separate receiving chambers and a control that controls that the receiving chambers are filled alternatingly with liquid while the receiving chambers that are not being filled are drained. The receiving chambers are sealable relative to the vacuum side of the aspirator motor by main valves that are preferably mechanically connected.

Liquid aspirator

A sludge extractor with a receiving tank, on which a suction connection for a suction element, which draws in a sludge-containing liquid, and a discharge connection for discharge element, which discharges the sludge-containing liquid, are mounted, and with a motor for driving a suction device in such a way that a negative pressure is created in the receiving tank, which negative pressure keeps a vacuum valve on the discharge element closed, is characterized in that the negative pressure acting on the vacuum valve is lower than the pressure which acts on the vacuum valve as a result of the sludge-containing liquid when a predetermined fill level is reached by the sludge-containing liquid in the receiving tank.

The invention relates to a pool filter comprising a housing, which can be supported on a ground side on the base, a longitudinal axis and a transversal axis, and a water inlet, a channel outlet and a pool outlet which are embodied in the housing wall thereof. A flow path from the water inlet to the pool outlet is embodied in the housing on the filter in the filter system and a filter device is arranged in the flow path. The invention is characterised in that a pre-filtering unit is arranged in the flow path in front of the filter device.

Pool filter with a pre-filtering unit

A filter device with a UVC lamp for filtering fluids, with a lamp housing, which is installed in a flow of the fluid to be filtered and has a principal axis, is characterized by the fact that at least one cleaning element is arranged in contact with a fluid-side surface of the lamp housing and can rotate about an axis of rotation that coincides with the principal axis.

A filter device for filtering flowing liquids comprises a compressible filter medium in a vessel and a device by which the filter medium can be compressed by means of an actuation handle, so that impurities can be pressed out of the filter medium. In addition, the filter device contains a multipath regulator which can be adjusted for filtering, back-rinsing and clear-rinsing by means of three flow paths. It is also possible for the filter device to be outfitted exclusively with a multipath regulator or a compressing device.

A submersible electrical appliance includes a housing having a water-tight function chamber and at least one water-tight junction chamber, the housing having a bulkhead wall separating the function chamber from the junction chamber, and internal water-tight compression electrical fittings passing through the bulkhead and extending beween the function chamber and the junction chamber.

Submersible electrical appliance, especially a lamp

A pool filter with a housing having at least one opening for an inlet and at least one additional opening for an outlet, in which housing at least one filter pad in contact with its margins is arranged with both its sides freely accessible such that one side of the pad is connected to an inlet chamber and the other side of the pad to an outlet chamber, is configured for the purpose of easy adaptability to various filter capacity and fineness requirements and for easy handling and maintenance such that the housing includes a plurality of flatly stackable housing elements each with at least one filter pad which form terminal units and intermediate units of a pool filter set, the intermediate units being configured identical to one another and having next to the filter pad a bottom for separating the inlet chamber and outlet chamber of adjacent filter pads.
