T series self-priming trash pump is the latest generation product base on US Gorman-rupp T series trash pump technology and craftwork. It is designed for economical & trouble-free operation in handling solid-laden liquids and slurries.

The self-priming centrifugal T Series is the standard for industrial and sewage applications. The heavy duty construction and easy-to-service design have made T Series pumps the standard in the industry. The combination of different sized pumps, impeller trims and speed variations ensure that the correct capacity pump will be matched to the exact requirements of your system, whether it"s a small sub-division or a large waste collection system. These pumps feature a large volute design that allows them to reprime automatically in a completely open system without the need for suction or discharge check valves - and they can do it with the pump casing only partially filled with liquid and a completely dry suction line.

Two-vane, semi-open, solids handling impeller handles up to 3" (76 mm) diameter solids, depending on pump model. Pump out vanes on impeller shroud reduce foreign material buildup behind impeller and reduce pressure on seal and bearings for extended pump life.

Removable cover plate provides quick and easy access to pump interior without disconnecting piping. Clogs can be removed and pump returned to service in minutes. Impeller, seal, wearplate and flap valve can also be accessed through cover plate opening for inspection or service.

T Series pumps feature replaceable wearplates which fasten to the cover plate and can easily be removed for inspection or service. No expensive castings to replace.

Removal of rotating assembly allows easy inspection of pump shaft or bearings without disturbing pump casing or piping. On most models, simply remove four bolts from the back of the pump and the rotating assembly slides out.
