Tornado rotary lobe pump for sludge conveyance
NETZSCH Pumpen & Systeme GmbH has developed the full service-in-place (FSIP) Tornado T2 rotary lobe pump designed for the various sludge conveyances in sewage treatment plants.
The Tornado T2’s FSIP design improves access for inspection, cleaning, service, and replacing parts. Simply removing the cover plate on the Tornado T2 allows quick and easy access to the pump chamber. The rotors can be removed and replaced easily and quickly because they are not bolted or keyed to the shafts inside the pump head. The rotors’ geometry allows their independent removal without the need for special tools.
Portable dewatering pump
The Allegro Sludge Pump has been designed for pumping standing water containing sand, solids, leaves or debris at a maximum of 50 gallons per minute. It is submersible to 39 feet with a continuous running water level to 3.5”. ½ hp motor. Allegro said it has created a portable with built in handle for easy transport and quick use.
The pump offers continuous operation at low water levels and extended dry runs without overheating the motor. This portable, submergible pump is excellent for manholes, vaults, construction sites, and all dewatering needs. The unit features a fire hose quick connect fitting. The Pump Discharge Hose is made from PVC with a collapsible design for compact storage and fire-hose quick-connect design 50’ x 2”.
Filter presses driven by compressed air
Andritz Separation has developed a product series of filter presses. The SP series is a so-called “air-over-oil” filter press driven exclusively by compressed air - a power connection is, therefore, not required.
With the new SP series, Andritz is primarily targeting the process and wastewater industries. Air-over-oil filter presses are used wherever there is no power connection available or possible in a process line. By deliberately dispensing with electrical equipment, the SP series is a further development of the filter presses designed for manual operation only.
The heart of the new press is the hydraulic unit operated by compressed air. Once supplied with air, the pneumatically driven high-pressure pump generates up to 400 bar hydraulic pressure.
