Gorman-Rupp’s T2A61-B is the smallest of their “T Series” range of wastewater pumps and is a cast iron self-priming pump (centrifugal) equipped with a 316 stainless steel impeller, seal plate and wear plate and a 17-4 PH stainless steel shaft for applications where wastewater is corrosive. They are also suitable with pumping raw sewage because of their solids handling capacity, their excellent NPSHr characteristics and their re-priming capability. They are also available in various other materials of construction, including hardened iron (approx 400 Brinell) internals for abrasive applications, and CD4MCu (duplex stainless steel) for applications where the wastewater is both corrosive and abrasive.
The T2A61-B is an excellent solids handling pump, being able to handle spherical solids up to 38mm in diameter, and because of its self cleaning wear plate system, is able to handle stringy materials such as rags, gloves and plastic bags. The pumps are mounted “high and dry” above the wet well, giving operators easy access to the pumps, and they have a large removable cover plate which makes maintenance and removal of any blockages much simpler than that of submersible pumps.
The pump has 50mm suction and discharge ports and is capable of flowing to 12 l/s and heads to 32m. This self-priming pump can operate on suction lifts to 7.6m, and is capable of re-priming from 7.3m with a completely dry suction line and only a half casing full of water, making it ideal for continuous, unattended automatic operation.
