Pump & Valve were approached by a customer with an application of packaging honey on a plastic jar packaging line. The pump needed to draw from several different tanks, having a suction line up to 6 metres long and the discharge being into the packaging line in the room next door, that fills honey jars varying in size.
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!
