Grit Pump News & UpdatesEGGER Grit Pumps in the Field & Other Updates
In the old days, antiquated grit pump technologies were designed using a cup-style impeller which included a rim around the outside diameter or circumference of the impeller. This style impeller cannot be trimmed and requires use of v-belts to change the pump speed to adjust the discharge head pressure or flow.
Egger Turo Sludge Pumps are ideal for CAMBI’s Thermal Hydrolysis treatment of sludge and bio-degradable waste for wastewater treatment, food waste or co-digestion projects.
Problem: Non-clog pumps cannot pump fibrous wastewater rags without clogging. Solution Egger: 4 inch pump & below use Turo model “TA” fully recessed vortex impeller pump
(4 x 3 inch suction/discharge passes a full 3 inch non-compressible)
This Egger Turo Vortex pump type TV 71-80 H6 for grit is running since 27 years without failure at the sewage treatment plant in Mary Esther, a beach community neighboring Fort Walton Beach in Florida. High sand loading from the beach results in pumps that wear down...
In the mechanical pre-treatment of wastewater treatment plants, the grit removal pumps used on washers and classifiers are exposed to very harsh conditions.
Grit trap pumps with different material designs (hard chrome, ceramic coating, rubber coating, chrome-molybdenum chilled casting) compete in a comparative test under hard and real conditions to cope with the abrasive medium of a “grit / water mixture”.
