APPLICATION 4: MULTI-PURPOSE PUMP
The unique and robust design of the EBP®allows the pump to be used in a number of different applications as
to those described above. The EBP®is a centrifugal pump with an impeller driven by an electronically
commutated motor. This totally removes the problem of brush wear encountered on conventional motors with
their mechanical commutation systems. The design ensures a hermetic seal between the pump and the
electronic motor without the need for a shaft seal. Through the elimination of the mechanical commutator the
durability of the pump is only practically limited by the mechanical life of the rotor bearings. In addition the
noise emissions are reduced by the small amount of moving parts. The pump has an axially orientated inlet and
perpendicular outlet.
The EBP®in fact may be used in all situations that require a water flow-rate of up to 15L/min and where a
positive-head is available. Such applications may include:
♦Go-Kart Water Pump – The EBP®may replace an existing non-pumped thermosiphon circulation system or
compliment the existing system. This is on the condition the system requires 15 L/min or less flow rate.
♦Camping/Caravan/Recreation- the EBP®could be used in a variety of arrangements where pumping is
necessary: outdoor showers, sinks, toilets, taps etc.
♦Marine – The EBP®may be used to compliment the existing water pump on inboard motors similar to the
automotive needs described earlier, increased cooling and the prevention of heat soak after engine shut
down.
Warning: The EBP®is only splash resistant, therefore to achieve life specification and preserve warranty at
no point should the EBP®be fully submerged.
♦Solar Heating – The EBP®may be used to circulate water through 12V solar hot water systems.
♦Irrigation – The EBP®may be used to pump water through irrigation systems, which require water flow of
less than 15L/min.
Other situations not described above may be suitable for the EBP®. The technical specifications for the EBP®as
well as the performance curve of the EBP®have been detailed below to help with any decisions on other
applications. Advice is available from Davies, Craig and we would very much appreciate feedback on your
experiences.

These installation instructions will suit most situations but there are many conditions of engine design,
environment, and the kind of motoring involved, which may call for other arrangements not described
here. Advice is available from Davies, Craig and we would very much appreciate your feedback.
