Cold War pulped by Landia’s cutter pump

Posted: Tuesday 11th April 2006

Millions of out-of-date water purification tablets that were stored during the Cold War in case of nuclear attack have been reduced to a pulp by a Landia MPTK cutter pump.

Faced with the task of safe and responsible disposal of over 15 million tablets, including masses of foil blister packaging, Staffordshire-based C.D.Bissell Engineering needed a highly durable pump that would not clog up.

By externally mounting the Landia MPTK on the side of a converted hopper, C.D.Bissell were able to load and process 110 boxes of tablets in a single batch, equating to 8,250 strips, 82,500 tablets. The cutter pump can actually handle much more volume than this, but batch sizes were restricted by health and safety requirements.

Benefiting from Landia’s exclusive external knife system, the 18.5kW cutter pump successfully kept its inlet opening free of the blister-pack and tablet impurities to produce the highly effective pulverisation required by this demanding application.

Tom Craggs, Design Engineer at C.D.Bissell Engineering, commented: “The MPTK has enabled us meet the stringent requirement laid down by our water company customer for the most effective disposal. This Landia cutter pump refuses to clog up, so we have no downtime or repairs to worry about”.

As an added asset management benefit to C.D.Bissell and the water company, the adaptability of the Landia MPTK means that it has also been utilised by the engineering business for a Mobile Rapid Heat Exchanger, designed by C.D.Bissell Engineering, where it is now chopping and pumping coarse sludge at around 403m at a head of approximately 11 metres.

With motors ranging from 0.55kW to 30kW, Landia’s MPTK has a specially-designed pump casing and impeller, and is also available in a high pressure version that is capable of pumping matter more than twice the distance of conventional equipment.
