Abstract
A pump assembly is disclosed. The pump assembly including an outer casing having a first end, an opposing second end, and a cavity therein; a discharge tube positioned in the cavity and exiting the first end of the outer casing; a check valve positioned in the cavity and operably connected to the discharge tube by a coupling; and a multi-float control assembly positioned in the cavity, the multi float control assembly including a bottom float check valve operably connected to the discharge tube by the coupling and an upper float check valve connected to a vent exiting the first end of the outer casing.
Claims8
A multi-float assembly for a well pump, comprising:
- a discharge tube for being positioned in a cavity of a well pump housing, the tube having first and second ends;
- a pump head connected to the first end of the discharge tube;
- a coupling connected to the second end of the discharge tube;
- a bottom float check valve operably connected to the discharge tube by the coupling;
- and
- an upper float check valve connected to a vent opening of the pump head, wherein the bottom float check valve and the upper float check valve each include a housing having a plurality of apertures formed through a wall of the housing.
A pump assembly, comprising:
- an outer casing having a first end, an opposing second end, and a cavity therein;
- a discharge tube positioned in the cavity and exiting the first end of the outer casing;
- a check valve positioned in the cavity and operably connected to the discharge tube by a coupling;
- a multi-float control assembly positioned in the cavity, the multi float control assembly including a bottom float check valve operably connected to the discharge tube by the coupling and an upper float check valve connected to a vent exiting the first end of the outer casing;
- and
- a multi-function valve connected to the first end of the pump, the multi-function valve includes
- a housing having an internal bore therein;
- a spool valve positioned in the internal bore, the spool valve configured to seal and direct a flow of compressed air and exhaust;
- a spring operably connected to the spool valve, the spring biasing the spool valve in a normally open exhausting position;
- and
- a check valve positioned in the internal bore at an anterior end of the spool valve, the check valve preventing contaminates from flowing through a compressed air exit of the spool valve.
A pump assembly, comprising:
- an outer casing having a first end, an opposing second end, and a cavity therein;
- a pump head disposed at the first end of the casing;
- a discharge tube positioned in the cavity, the discharge tube having first and second ends, the first end being connected to the pump head;
- a coupling connected to the second end of the discharge tube;
- a check valve positioned in the cavity and operably connected to the discharge tube by the coupling;
- and
- a bottom float check valve operably connected to the discharge tube by the coupling;
- and
- an upper float check valve connected to a vent opening of the pump head, wherein the bottom float check valve and the upper float check valve each include a housing having a plurality of apertures formed through a wall of the housing.
