Patent number: 10808707Abstract: A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, the pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.Type: GrantFiled: August 2, 2018Date of Patent: October 20, 2020Assignee: Nuhn Industries Ltd.Inventor: Ian Nuhn

Patent number: 10788052Abstract: A fluid pump having at least two pump heads in series permits pumping fluid at both high pressure and high volumetric rate. Each pump head has at least two fluid conduits in fluid communication with a housing, the housing containing an impeller for drawing fluid through an inlet in the housing and moving the fluid through the fluid conduits. The at least two fluid conduits of one pump head combine fluid flow at the inlet of a neighboring pump head to provide a single flow of fluid through the inlet into the neighboring pump head. A drive structure passing through the inlets between two pump heads is configured to commonly drive the impellers in the housing of each pump head.Type: GrantFiled: March 24, 2017Date of Patent: September 29, 2020Assignee: Nuhn Industries Ltd.Inventor: Ian Nuhn

Patent number: 9488190Abstract: A pump for immersion in a fluid reservoir has an extensible body and a fluid conduit. The length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. The pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump has a bottom housing with a bottom inlet and at least two, preferably at least three, tangential fluid outlets that are upwardly angled towards the conduit. The outlets may be merged with the fluid conduit. An impeller within the housing is shaped to transfer fluid tangentially and upwardly within the housing to co-operate with the upward angle of the outlets. These features reduce fluid pressure loss and thereby increase fluid flow rate through the pump for a given input power.Type: GrantFiled: December 15, 2014Date of Patent: November 8, 2016Assignee: Nuhn Industries LimitedInventor: Ian Nuhn
