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!
