Borger – Rotary Lobe Pumps & Grinders

Borger Rotary Lobe Pumps are positive displacement pump conveying the conveyance of low to high, viscous and abrasive materials. to and from thickeners, belt presses, centrifuges, rotary presses, digesters , air entrained fluids, DAF, and industrial slurries. They handle thick solids greater than 2% up to 2000 gpm and pressures up t0 150 PSI. Rotary lobe pumps can run dry and are capable of self-priming. The rotation of the pair of lobes increases suction chamber pressure and creates a vacuum on the priming side of the pump drawing liquid into the pump chamber.

Suitable for Run Dry conditions.
Small Footprint
Pumps froth, DAF or air entrained fluids/sludges
Self Priming
Wearing parts replaced (seals, lobes and wear plates) without removing attached piping.
Front wear plates reversible for extended use.
Applications
Wastewater: Transfer to/from Thickeners, Belt Filter Presses, Screw Presses, Centrifuges, Digesters, RAS/WAS
Biodiesel slime
Pesticides – handles crystals and high temperatures
Sodium Sulphate:
Amine recycling plant where amine sulfate delivered is processed in a rectification system. Caustic soda reacts with the sulfuric acid contained in the amine sulfate forming sodium sulfate.
Slaughterhouse: Animal Blood – handles with ear tags
Bentonite – horizontal flushing bore rigs
Natural Latex
Adhesives – tile and parquet
Hydrogen peroxide, Tristyrylphenol, Fatty acid methyl ester, Melt
Cosmetics, Soap, Detergents, Vegetable/animal fats, Glycerine residues, Viscose fiber, Soapstock
BLUEline Pump Series
BLUEline series of pump is ideal for transferring sludge to and from thickeners, belt presses, centrifuges, rotary presses and digesters.

Maintain in Place
The pump is designed so wear components can be replaced through the quick-release cover of the pump
All maintenance work can be done without removing the pump from the suction or discharge piping or the drive system.

Optimized Rotor to Maximize Efficiency – Replaceable lobe tips
Rotors available in variety of configurations and materials.
Popular among operators/maintenance staff are lobes with replaceable rubber tips. If pump wears, replace the tips versus entire lobe.
Lobes can be retrofitted to optimize performance in existing pumps.
See video below on ease of replace lobe tips in-situ:

Key Features

Mechanical Seal Replacement
Borger has replaceable stationary and rotating seal faces that can be economically replaced without replacing the entire seal components. See the following video to illustrate the ease of seal replacement:

ONIXLine Rotary Lobe Pump
The ONIXline rotary lobe pumps were developed by means of the most advanced flow simulation technology and experience in rotary lobe pump construction for Industrial applications. The pump stands for gentle, practically pulsation-free pumping with maximized efficiency. The large sealing chamber makes the use of different sealing systems possible.

Multicrusher
Grinder/Chopper upto 1,400 usgpm that reliably chops coarse material such as sludges, fibers, wood pieces, plastics, membranes, textiles and many more and ensures that downstream machines and pumps operate smoothly. The Multicrusher homogenizes the medium thereby facilitating the pumping process.

Quick release cover – Access to all wetted parts
Axial casing protection
Cutting blades
Shaft seals – no removing from suction or discharge pipes or drive motor
Casin
Quench with seal leak monitoring
Bearing frame

Multichopper
Multichopper is a perforated disk chopper with a central perforated disk and high performance blades for using with liquid containing coarse solids. The multiple blade cutters can be adjusted from the outside. A special technology is used to continuously keep the knifehead with the axial fixed knifes pressed towards the shearplate which can be used from both sides.

The Multichopper is available in two models. The Multichopper plus is equipped with a debris collector, whereas the Multichopper pure is designed so that there is almost no space in which any parts in the medium can be stored.

Both models come in different sizes with throughput volumes of up to 1,760 usgpm.

Belt Dryer -Andritz

Andritz – Belt Drying System – provides highly desired Class A Biosolids in a highly marketable sludge pellet / granual. The process granulates the dewatered sludge in a mixer with product that has already been dried. The moist granulate produced here is distributed evenly over the belt in the dryer by a specially designed feed module. The even layer of material on the belt creates optimum conditions for even distribution of the drying air. This, in turn, is necessary for even heating and drying of the sewage sludge. The layer of material on the belt forms a
filter medium for the air flowing onto the granulate layer from above and thus prevents entrainment of dust. The low temperature of the drying gases (< 150°C) and the low dust content in the system facilitate safe operation. The dried material is not exposed to mechanical stress during drying and is pre-cooled before the dryer discharge. The technology – simple, convincing, and successful.

The belt dryer is particularly attractive economically because it uses waste heat with a low temperature.

Highly product quality of different sludges qualities due to variable back feeding.
Modular structure and simple design.
High availability.
Combination of tried-and-tested components from ANDRITZ SEPARATION sludge drying technologies.
More than 30 reference plants drying around 800,000 tons of dewatered sludge per year.
Installations include St. Joseph, Missouri and Cape Girardeau, Missouri.
Case Study – Cape Girardeau
Cape Girardeau constructed a new greenfield wastewater treatment plant in 2014 to meet new discharge limits and to overcome challenges with the original plant prone to flooding and sinkholes. Below are highlights of the project with a Water & Wastewater Digest Article, Optimum Biosolids Solution in April 2013.
