BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to pumps, and more particularly to pumps of the type typically used to form fountains in small outdoor ponds or the like.
2. Description of the Related Art
Prior art pumps have typically been of many shapes, primarily dictated by the shape of what is inside of the pump housing. Most of these prior art pumps tend to vibrate when they are placed on a surface above or below the water and this causes them to want to move from where they are placed or if they are plumbed into place, to cause the connections to loosen. Consequently there is a need for a pump which will overcome the aforementioned deficiencies of the prior art.
BRIEF SUMMARY OF THE INVENTION
The present invention relates to a pump for moving liquids having an elastomeric housing disposed around the pump. The housing has at least four sides which are primarily planar whereby the pump can be supported on the bottom of one of the flat sides by orienting the pump so that one of the primarily planar sides is down. This allows the pump to remain in such chosen orientation and the elastomeric housing, which is typically rubber, will substantially prevent vibration of the pump to be transmitted to the surroundings of the pump.
An object of the present invention is to provide an improved pump and combination pump housing.
Another object of the present invention is to provide an elastomeric housing for being disposed around a pump to allow the pump to be placed on one of at least four primarily planar sides whereby the pump can be supported on the bottom of a pool of water having a flat surface thereon by orienting said pump so that one of the primary planar sides is down.
A still further object of the present invention is to provide a rubber or elastomeric housing which will substantially prevent vibration of the pump to be transmitted to the surroundings of the pump.
Other objects, advantages, and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.
