Pump & Valve were asked to look at an application to divert waste water from a dairy factory past a failing drain that could not be repaired. The application was made especially difficult as the customer had already installed a 5m deep below ground tank with a very small opening – far too small for a conventional submersible pump.
A large concrete products manufacturing site in Auckland were having issues with the pumps pumping waste water from their settlement pond. Mechanical seals would fail regularly from being dry run and – if the dry running did not wreck them – the fine cement particles in the waste water would. Typical mean time between services was 6 months or less.
A waste water treatment plant had been using Bredel pumps for pumping sludge around the plant. The hose life that they were getting from the Bredel hoses varied between 1,000,000 – 3,000,000 revolutions. This life was less than ideal and – as the operator put it – they always failed on a weekend or a Friday night!
A client approached Pump & Valve with a requirement to pump the steak and gravy filling for a well-known pie brand. The filling was for their premium pies so the pump had to be able to pass larger than normal pieces of steak (2cm³ – 3cm³) without damage. The steak and gravy filling had to be pumped directly out of the cooker so not only was the mixture hot but the steak was very tender and pulled apart very easily.
