wastewater pump

The T8A3S-B is the 2nd largest in the Gorman-Rupp range of “Super T Series” self-priming sewage and trash pumps. They are used extensively by heavy industry, food processing plants etc as wastewater pumps, and they are used municipally as sewage pumps at sewage pump stations or at sewage treatment plants. This pump’s industry leading reliability makes it the ideal choice for continuous, unattended, automatic operation. The ability to re-prime for a “self-priming” pump is also extremely important for unattended operation, and this pump is able to re-prime to 7.0m at its maximum speed of 1350rpm, and can even re-prime to 5.2m at a speed as low as 950rpm.

The ability to re-prime is necessary for industrial wastewater pumps or self priming sewage pumps because a solid can get caught in the non-return flap valve of the pump when the pump stops at the end of a cycle, exposing the suction line to atmosphere. If the pump cannot re-prime the line with just a partially filled casing, the pump is out of operation. The Gorman-Rupp Super T and Ultra V Series pumps are designed to re-prime under these severe conditions, every single time. These guaranteed re-priming lifts are published on each Gorman-Rupp Super T and Ultra V performance curve.

The T8A3S-B is able to handle solids in suspension very well, including spherical solids up to 76mm diameter and even stringy materials such as rags, gloves, feathers and plastic bags. It does this better than most solids handling pumps because of its unique self cleaning wear plate system. Also, because it can be mounted “high and dry” above the wet well, monitoring and maintenance of this pump is much easier for operators, and chokes are much easier to remove than for any other pump.

As an additional weapon against choking when an application involves the handling of heavy loads of stingy materials [such as “wet wipes” or large quantities of rags], Gorman-Rupp have developed the 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. The T8A3S-B when fitted with the “Eradicator™” it called a T8C60SC-B.

The T8A3S-B has 200mm suction and discharge ports and is capable of flows to 150 l/s and heads to 32m. The pump is available in a variety of materials of construction to enable the pump to tackle corrosive and/or abrasive applications. These materials include G-R hard iron [approx 400 Brinell] for abrasive applications, 316 stainless steel for corrosive applications and CD4MCu [duplex stainless steel] for corrosive and abrasive applications.

Gorman-Rupp Spare parts are stocked in large quantities by Hydro Innovations so that customer pumps can be up and running fast when repairs are needed.
