water pump

Abstract

The water pump, for garden ponds and aquaria, has a pump housing (1) with a water inflow (3) and outflow (4) and a diagonal powered impeller (5) with a conical covering disk (6). The water inflow and outflow are at right angles to each other. The leading edges (8) of the impeller paddles (9) are aligned at a diagonal, parallel to the water flow, forming a sealing gap (10) with the inner contour of the pump housing. The impeller is of an injection molded plastics with at least one metal ring.

Description

technical field [0001] The present invention relates to a water pump especially for use in garden ponds and aquatic life areas. Background technique [0002] In practice, pumps are common in this field, which have motor-driven radial impellers so that the water to be pumped is deflected by a deflection angle of 90°. The pump thus justifies the requirements in a corresponding arrangement, so that a deflection of approximately 90° must generally be carried out. Although such water pumps generate a relatively high delivery pressure, they have a relatively small delivery volume. If large delivery volumes are to be achieved with such pumps, the necessary power consumption is very high. Contents of the invention [0003] It is therefore the object of the present invention to provide a water pump with improved efficiency with regard to the delivery volume. [0004] The invention provides a water pump used in garden ponds and aquatic organisms areas, comprising a pump casing wi...
