Friction lock design for adjustable pump head to allow for 360 deg rotation

Abstract

A method and apparatus are provided for coupling a pump head (1) and a motor housing (4) of a pump together so that a rotational positioning ring (2) of the pump head (1) frictionally engages a snap ring (5) of the motor housing (4) so as to allow for 360 DEG rotation of the pump head (1) in relation to the motor housing (4), where the orientation of the pump head (1) and the motor housing (4) are adjustable in relation to one another so as to allow an end user to set the orientation of the pump in any configuration. The positioning ring (2) has a plurality of members separated by slots for radially flexing when the rotational positioning ring (2) is axially coupled over the snap ring (5) of the motor housing (4). Each of the plurality of members has a rim so as to form a raised edge for frictionally engaging a corresponding raised edge of the snap ring (5) of the motor housing (4).

Description

technical field [0001] The present invention relates to a pump and more particularly to a method and device for coupling a pump head and a motor housing of a pump. Background technique [0002] During installation of a pump into certain equipment or installations, due to space constraints or possibly for some other reason, it may be desirable or may even be necessary to allow the pump head to be able to rotate relative to the pump housing in order to optimally fit the pump to a given device. For example, in order to install a known pump, typically the fittings or hose fittings of the pump head must be coupled to the appropriate hose of the equipment or device and one or more brackets of the motor housing must be secured. It is firmly fixed on some structure of the equipment or device, such as the housing or the corresponding bracket. However, existing pump designs typically require the screws to be removed in order to allow the pump head to rotate relative to the motor hou...

Problems solved by technology

However, in order to allow the pump head to rotate relative to the motor housing, existing pump designs often require the screws to be removed

In addition, most pump designs only allow two positions that are 180° apart from each other. In fact, if the pump head needs to be rotated, the installer can only rotate the pump head face down.

[0003] For this reason, current pump designs are limited to face-up or face-down orientations

Additionally, screw removal often requires tools to be available to the end user or installer and can lead to loss of components and the possibility of parts shifting during reassembly

Typically, most pumps are screw mounted to the motor or housing, which limits the amount of rotational movement they can achieve at one time
