It is a common experience that although many would expect that centrifugal slurry pumps would be suitable for most and slaughterhouse waste pumping applications, they fall short when used in the biogas industry. For biogas processing, it is necessary to pump the entire waste, including the bones because even the bones are a useful biogas source.
In fact, pumping slaughterhouse waste which includes all sorts of shapes, and sizes, of bones must be just about the most demanding requirement for any pump. Although, it may be similar to some types of food waste the added presence of sharp and hard bones makes the difference.
To ask a food industry type progressive cavity pump to do this work, or even a heavy-duty screw feeder, may at first appear viable.
But, operators seeking abattoir waste pumps should take care when buying, because wear rates due to the abrasiveness of bone can be a real concern and in the case study which follows it was not until a different pump entirely was specified and installed that a solution was found.
In this article, we provide a case study of a particular abattoir where VERDER Pumps solved a vexing abattoir waste pump blockage and wear problem.
Verder can also supply your food waste pump, to their competitive food waste pumps price list. They have a well-reviewed food waste pump for sale, and they also have food waste and slurry pumps for sale in Northern Ireland, Scotland and throughout the UK.

So, when the biogas industry process designer seeks to pump this material both into trucks for transport, and then subsequently from the truck at the biogas plant into the biogas digester, the pumps need to be extremely hard-wearing and blockage free.

SOLUTION TO MAKING BIOGAS THROUGH PUMPING SLAUGHTERHOUSE WASTE
A Danish biogas plant had frequent problems pumping waste of this kind because the waste contained large-sized bones.via www.verderliquids.com
Sometimes the percentage of solid matter increased up to 10-13 %.
Until now the abattoir company used a heavy duty screw feeder, which blocked regularly because of the bones.
Because the feeder was submerged in a large container, downtime was extensive to release the screw feeder again. In a later stage a progressing cavity pump tried to manage pumping this difficult mixture, but the stator suffered extreme wear due to the sharp edged bones.
The required flow had a capacity of 360-540 m3/h. The differential head is approximately 10–15 m. The pump is feeding a large-sized bone crusher.
A VerderHUS screw channel pump was offered for a test period to pump the slaughter waste from the tank to the bone crusher. The pump was not executed with a normal electric motor but was coupled with a hydraulic drive, supplied by the client. The hydraulic drive offers very high torque required in the technical specification (360-540m3/h). The pump speed could be adjusted quickly when needed.
The slaughterhouse waste is now being pumped by the submerged HUS screw channel pump to the homogenizing tank smoothly.
The VerderHUS screw centrifugal pump was tested successfully and offered the perfect solution. Four years after installation the pump runs fully submerged and does not block. The pump is even operating as a bone breaker!
The only two pump parts that have been replaced were an impeller and a suction casing. The company is very satisfied and has installed an extra pump for greater capacity.
