Withdrawal device, useful for floating sludges, oils and fats in small sewage treatment plant, comprises pump with flexible pump inlet, suctioning element fixed vertically pivotable on hanging device with rigid pump outlet

摘要

Withdrawal device (1) comprises a pump (2) with a flexible pump inlet, where a suctioning element (10) is fixed vertically pivotable on a hanging device with a rigid pump outlet with a carrying handle and a variable locking element via a height-adjustable hinge of a height adjuster (7). A float is fixed vertically and horizontally at the suctioning element, where the float holds the suctioning element in a working position with respect to a water surface. At least two suction regulating openings (15) are introduced into a suction-platform of the suctioning element.

A float is fixed vertically and horizontally at the suctioning element, where the float holds the suctioning element in a working position with respect to a water surface. At least two suction regulating openings (15) are introduced into a suction-platform of the suctioning element. The sum of the cross-sections of the suction regulating openings are implemented smaller than the cross-section of a suction opening of the suctioning element.
