摘要： There is disclosed a connector which is sometimes referred to as a pitless unit in industry for use in a pumping system including a pump, well casing, a discharge pipe to guide liquid horizontally away from the pump, and a drop pipe to guide the liquid up from the pump towards the discharge pipe. The connector acts to connect the drop pipe and discharge pipe in fluidic communication while allowing the pump there beneath to be accessed from the surface of the ground. The connector features an outer housing and internal spool which is locatable in the housing in a seated position. An interior surface of the housing and surfaces of the spool which collectively define a chamber through which the liquid flows, when the spool is in the seated position, are weld cladded with a metallic cladding material so as to resist corrosion and erosion of these wetted surfaces of the connector.

摘要： There is disclosed a connector which is sometimes referred to as a pitless unit in industry for use in a pumping system including a pump, well casing, a discharge pipe to guide liquid horizontally away from the pump, and a drop pipe to guide the liquid up from the pump towards the discharge pipe. The connector acts to connect the drop pipe and discharge pipe in fluidic communication while allowing the pump therebeneath to be accessed from the surface of the ground. The connector features an outer housing and internal spool which is locatable in the housing in a seated position. An interior surface of the housing and surfaces of the spool which collectively define a chamber through which the liquid flows, when the spool is in the seated position, are weld cladded with a metallic cladding material so as to resist corrosion and erosion of these wetted surfaces of the connector.
