Waste Water From A Concrete Plant

Waste Water From A Concrete Plant


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.


Pump & Valve offered a Grundfos centrifugal pump with a custom innovative seal design that negated the dry running issue and the also the abrasion issue. As a result the pump has run for over 3 years without being touched.
