Food Waste Pumps / High Solid Content / Viscosity Changes / Self-Priming

Upon completion of the anaerobic digestion process, the digestate and waste water is pumped from the tank by a lobe pump for further use as fertilizer. The final product of biogas is then filtered and processed further, ready to be fed into the national gas grid. By receiving outside waste from households, restaurants and local industry, the brewery can also charge per tonne at a rate lower than that of the Landfill Tax. Some of the gas is also tapped off and used for wagons that collect waste food.

Much of the process is self-wetting, and thus doesn’t need additional liquid to be added so that it can be processed efficiently because food waste has such high water content. Accuvon pumps are ideal for handling this type of material, which has the consistency of slurry, especially if it contains eggshells which can be very abrasive to pumps. Because of its high viscosity ,Accuvon lobe pump is suitable for sludge and slurry, paper pulp, effluent, mash and many other fluids which are viscous or have a high solid content

Viscosity changes

Resistant to clogging even when pumping fibred fluids and unaffected by viscosity changes, Accuvon lobe pumps is suitable for water treatment including thick sludge, thickened media, slurries, sewage and waste water. In food and beverage, it can handle diatomaceous earth, slurry, yeast, sugar, gelatine, hop, corn and malt, as well as agricultural waste such as chicken necks, bones, compost, biogas and pet food.

Because Accuvon’s technology can handle both viscous material and is tolerant to abrasive waste, even in where a product needs to be drawn from a tank, a Accuvon lobe pumps provides exceptional suction lift, so it can vacuum the dregs up and abrasion is not an issue. It can also run dry without damage.

Advantages of this Accuvon rotory lobe pumps

operating principle

• Self-priming, valveless, positive displacement pump

• Designed with two shafts with parallel axes

• The shafts move relatively to one another thanks to external timing gear

• The displacers (=rotors) roll off each other with minimum axial and radial clearance

• In every position, the rotors and casing close the suction chamber against the pressure chamber

• Gentle, low-pulsation pumping

• For viscous, solid, abrasive or shear-sensitive media

Accuvon's range of rotors –the Premium rotor

Premium profile– of biogas rotors

• Large sealing area

• Effective wiper edge

• Pressure-resistant

• Made of steel, stainless steel or plastic

axial and radial casing protection

To protect the pump casing from abrasive media and solids, we developed replaceable casing protection plates and liners several years ago.

The casing protection is replaced in a few steps, based on the MIP principle.

Easy maintenance– Maintenance in Place

• Reduced maintenance times and downtimes

• Maintenance at installation site by customer's in-house staff
