A Gorman-Rupp VS3A60-B self-priming wastewater pump from Hydro Innovations was installed at a massive beef processing operation in Ipswich,
overcoming the priming and reliability issues of the existing pump.
The largest beef processing plant in the southern hemisphere, the JBS
Australian Dinmore facility uses numerous and varied pumps for their operation.
Some time ago, their end suction centrifugal pump installed in a cattle yard
run-off application had begun giving reliability problems. The large suspended
solids in the fluid being pumped led to choking issues with the pump. Since it
relied on a foot valve to keep the suction line primed, any solid caught in the
foot valve would cause the pump to lose prime.
The application was quite complicated since the pump was delivering 20
litres per second (l/s) at a pressure of 800kPa and was on a suction lift in
excess of 5 metres.
Following a site inspection and a hydraulic analysis of the system,
Hydro Innovations recommended their Gorman-Rupp VS3A60-B, the only two stage
self priming solids handling centrifugal pump on the market. Featuring a cast
iron construction, the pump has a large inspection cover to allow access to
pump internals for inspection and/or service.
Key advantages of Gorman-Rupp VS3A60-B self priming wastewater pumps
include ability to handle spherical solids up to 63mm in diameter, resolving
potential choking issues; internal clearance adjustments accomplished in
minutes, allowing operators to keep the pump at peak operating efficiency for
the life of the asset; and excellent priming and re-priming capabilities
ensuring the pump won’t lose its prime even if solids get caught in the system.
The VS3A60-B is part of a family of Gorman-Rupp high performance, high
head self priming wastewater pumps that can deliver flows from 10 l/s through
to 120 l/s, and heads to 95 metres. All the pumps in the range have replaceable
self-cleaning wear plates to efficiently handle stringy materials such as rags
and gloves, and they can operate on suction lifts up to 7.6 metres. Being self
priming pumps, they are safer to maintain than submersible pumps because
operators do not have to work over water or with cranes or heavy swinging
Since its installation six years ago, the Gorman-Rupp pump has been
operating at the Ipswich beef processing plant with minimal operator
