Embodiment Construction

[0023] Figures 1 to 4 A hose pump 10 according to an embodiment of the invention is shown, which can be used, for example, as a conveying device for paint application devices, commonly also referred to as motorized paint rollers, in order to convey especially thin liquid dispersion paints, latexes Paints, water-dilutable primers, lacquers, oils and water-based wood preservatives. The hose pump 10 comprises a pump housing 12 which receives a drive motor, not shown in detail, and a pump head 14 arranged on the pump housing, which has a deformation body 16 in the form of a pressure roller which can be driven by the drive motor and a pump hose 18 which is supported on the pump housing 12 and which is mechanically deformed by the deformation body 16 during operation of the hose pump in order to move the medium to be conveyed through the pump hose 18 . A suction line 22 on the one hand and a pressure line 24 on the other hand are fastened to the pump hose 18 via corresponding coup...

Abstract

A peristaltic (hose) pump (10) e.g. for paint comprises a pump housing (12) that receives a drive motor and a pump head (14) that is provided with a deformation body (16) capable of being driven by the driving motor and a pump hose (18) supported on the pump housing (12), wherein, the pump hose (18) is mechanically deformed by the deformation body (16) during operation of the hose pump, so that a medium is pumped through the hose. The pump head (14) is detachably fixed on the pump housing (12) via a fast locking mechanism (44) particularly capable of being manually operated, when the fast locking mechanism is transferred from an unlocking position to the locking position, gradually-increased pressure is loaded to the pump hose (18) via the deformation body (16).

Description

technical field [0001] The invention relates to a hose pump comprising a pump housing receiving a drive motor and a pump head having a deformable body drivable by the drive motor and a pump hose supported on the pump housing, wherein the pump During operation of the hose pump, the hose is mechanically deformed by the deformation body in order to move the medium to be conveyed through the pump hose. Background technique [0002] Such hose pumps are known in various designs from the prior art. They are particularly suitable for delivery of thin liquid dispersion paints, latex paints, water-reducible primers, lacquers, oils and water-based wood preservatives. Therefore, they are often installed in paint application devices called motorized paint rollers. Furthermore, hose pumps are advantageous due to their simple and cost-effective construction, their low maintenance effort and their uniform and relatively shock-free delivery properties. [0003] For long-lasting and troubl...
