Why wet prime pumps are better in trash handling

Traditional engine drive trash pumps are ideal for pumping applications
in environments where supplying power for an electric pump is not practical.
Trash pumps come in two options – a wet prime pump where water is added to the
pump chamber to prime the unit, and a dry prime pump, which uses a vacuum pump
or compressor to assist with priming.

Simplicity is a major advantage in wet prime trash pumps; unlike dry
prime pumps, they don’t require complicated priming apparatus in the form of
complex compressors or vacuum pump systems. Conventional dry prime pumps use an
induction style system not designed for trash handling. Additionally, wet prime
trash pumps are easy to set up, use and maintain. With fewer moving parts, they
also deliver reliable performance.

“Dry prime pumps have the ability to ‘snore’. That means they will
automatically reprime as the water level varies,” said Aussie Pumps’ Product
Manager, Brad Farrugia. “However, for straightforward water transfer or
dewatering a flooded construction site, a simple wet prime pump is a more cost
effective option,” he said.

To transfer typical construction site water, industry experts recommend
heavy-duty trash pumps capable of handling silt and sand laden water without ‘choking’.
Australian Pump Industries offers a complete range of trash pumps from 2″-6″ in ‘Mine Boss’
configurations. These pumps come designed for tough work at construction sites.

Key features of Aussie’s Mine Boss range of trash pumps include super
heavy-duty 38mm fully galvanised frames with lifting bars and E-stops, battery
isolation, and optional bunded trays or even wheel kits; lifting bar at the
point of perfect balance designed into the frame to enable the unit to be moved
easily by crane or excavator on site where necessary; big open ‘non-clog’ style
impellers handling solids in suspension; ability to handle solids-laden liquids
such as flood water, slurry, and even effluent with solid concentrations up to
25% of the liquid volume; and flows of up to 6,000 lpm and heads as high as 47
metres.

The self-priming range offers a vertical lift of 7.6 metres with no
requirement for mechanical priming aids.

“A lot of contractors use dry prime pumps for site dewatering because they
don’t understand how simple the wet prime principle is,” said Farrugia.

Self-priming or wet prime pumps simply require the pump cavity to be
filled prior to starting for the first time. The pump will subsequently self-prime
as long as there is water above the impeller. An internal check valve ensures
the prime is held once the pump stops.

“Trash pumps have lower investment and maintenance costs compared to
vacuum primed pumps,” said Farrugia. Wet prime pumps can last 20-30 years with
regular maintenance.
