Abstract: A cover for a sewer basin with a pump is provided with upper and lower members. The bowl-like lower member has a central cavity which may be closed in a water-tight fashion by placement of the upper member onto the lower member in a frictional fit. A flanged surface on the lower member allows it to be sealed in water-tight relationship over a maintenance entry into the basin. A control panel for the pump is mounted in the central cavity. Access may be had to the control panel without a need to open the basin, and access may be had to the basin interior without a need for opening the central cavity or the control panel housed therein.

Abstract: An integral, readily installed, universal pump assembly has an integral, liquid-tight outer housing for supporting within a single liquid-tight containment vessel an electric motor driven pump, and discharging liquid from a discharge outlet of the pump. The assembly includes at least one normal high and low liquid level sensing control pneumatic pressure operated electric switch supported within the housing for deriving on-off switching control signals for controlling normal on-off operation of the pump. At least one liquid level sensing diving bell is supported on the housing and has at least one lower open end exposed to the liquid in the collection tank for deriving varying pressure pneumatic liquid level indicating signals for application to the pressure operated switch for deriving the on-off control signal.
