A large commercial laundry business in Sydney replaced their two aging
Gorman Rupp 14A20-B trash pumps with newer models from the same brand to ensure
continued service well into the future.
Installed in 1989, the two existing wastewater pumps had been operating
in a harsh environment, pumping used laundry water back to an internal
treatment plant. Since the business provided laundry services for a broad range
of customers from the healthcare, hospitality, food processing, manufacturing,
retail and workplace sectors, the Gorman Rupp units had to pump varying degrees
of wastewater, including suspended solids such as grit and cloth fibres.
Although the two existing pumps were still operating satisfactorily, it
was decided to replace them to ensure continued reliable service.
The decision to replace the old 14A20-B pumps with new Gorman Rupp 14A20-B
pumps was so that the pumps could be installed in the same footprint and would
line up perfectly with the existing piping arrangement.
Conventionally, newer models of older appliances don’t have the same
construction and are often less robust. Not so with Gorman Rupp pumps – the new
pump weighs exactly the same as it did 30 years ago, with the same quality iron
and steel used in its construction. The only improvements are the gasket and
seal materials as well as the bearings. Each and every Gorman-Rupp pump is
still tested at the factory prior to being shipped to the customer.
The new pumps were built onto bases with new motors by Hydro Innovations
at their Sydney factory, and the two pump sets were delivered and installed.
