the PPC browser aka 'minibrowser' only renders certain types of devices, such as lights, thermo, etc. It doesnt render devices such as TV, Stereos, etc.
If your pump device isnt specified as one of the devices, it won't render, thus won't be visible.
If you have a Pump object in Premise Home, XBrowser will render a Pump icon in the UI. The Pump's control will be a simple toggle button labeled "Power". The attached image was rendered using the original Xbrowser module.... I could just use a light icon but prefer the pump icon.
