Invoices will be submitted to Johnathan Browning, Johnathan.Browning@usace.army.mil (304)-664-3229.

Pumps are horizontal end suction pumps mounted on baseplates. The end suction design enables the pump to be installed horizontally in traditional, end suction design piping where the pump has an axial suction port and a radial center line discharge port. This design allows “back pull-out” capability. This means the pump usually can be easily serviced without removing the volute from the pipe system.
