Gorman-Rupp T3A71S-B Self Priming Wastewater Pump

Gorman-Rupp’s T3A71S-B is a “hardened fitted” self-priming, solids handling trash pump, so it is used for abrasive applications. This means that the impeller, seal plate and wear plate are fabricated from hardened iron or steel, to a hardness of approximately 400 on the Brinell scale. For extremely abrasive applications, the casing can also be supplied in hardened iron and the impeller can be supplied in high chrome (with a Brinell hardness of approximately 650).

The T3A71S-B is ideal as an industrial wastewater pump where abrasive particles are present in the wastewater, and they are also heavily used as grit pumps at the sewage treatment plants by Councils and Water Authorities around Australia. This pump’s excellent NPSHr characteristics and re-priming capability make it the ideal choice for continuous unattended automatic operation. The ability to re-prime for a “self-priming” pump is paramount for unattended operation, particularly at the likes of sewage pumping stations.

The T3A71S-B is also an excellent solids handling pump, being able to handle spherical solids up to 63mm in diameter, and because of its self cleaning wear plate system, it is able to handle stringy materials such as rags, gloves and plastic bags. This self priming pump is mounted “high and dry” above the wet well, making it easy for operators to access for maintenance and removal of any blockages.

When an application involves the handling of heavy loads of stingy materials such as “wet wipes”, the T3A71S-B can be converted to a T3C71SC-B, which means the pump is fitted with Gorman-Rupp’s new “Eradicator™” Solids Management System. The Eradicator™ system features an aggressive self-cleaning wear-plate incorporating a number of notches and grooves, as well as a patent pending lacerating tooth that helps break up stringy materials, scrape them off the impeller vanes and pass them through the pump – all without impacting performance or interrupting service. A special cover plate with the system includes a patented lightweight inspection cover that can easily be removed if necessary to inspect pump internals.

System benefits include improved operational efficiency, increased uptime, reduced maintenance costs, lower life cycle costs and easier access to the impeller. Operators will also find that the lighter cover-plate is easier and safer to work with.

Eradicator-equipped pumps do not require expensive chopper blades that need periodic replacement, but rely on passing large solids and stringy materials straight through the pump.

The T3A71S-B (self priming wastewater pump) has 80mm suction and discharge ports and is capable of flows to 25 l/s and heads to 32m. The pump can operate on suction lifts to 7.6m, and are available in other materials of construction, such as 316ss for corrosive applications and CD4MCu (duplex stainless steel) for corrosive and abrasive applications.
