Limited
Power Available
The
important thing to remember is that if you only have limited
power, you will only get a pump with limited capabilities and
lifespan – to get a high pressure or high flow-rate you
really need mains voltage. That being said there are a number
of pumps available to meet a variety of needs in 12v and 24v
(see Flojet 2130-700), some that come complete with crocodile clips for connecting
directly to a battery. Examples include small submersible pumps
for water or diesel transfer, boat bilges, small-scale irrigation
etc. Please note that the motors usually have a duty cycle of
around 20 minutes, and have a finite life depending on the number
of hours used. They can only be described as “light duty”
pumps.
There
are self-priming surface pumps (non-submersible) and bronze-bodied
peripheral pumps also available for other light duties such as
water transfer, pressure boosting and circulating. Again, as with
all low voltage pumps, they have a limited life span governed
by the hours usage they get.
We
can also supply 12v or 24v pumps for emptying drums, pumping
diesel into/out of lorries or earth-movers and even for removing
engine oil.
If
you have a choice, then we would suggest that you choose mains
(230v) as pumps tend to be more powerful, the motors don’t
mind being run for long periods and they certainly last longer
than low voltage ones.
One thing to note is that low voltage does not necessarily mean
low price !
If
you have a particular application that requires a pump, please
call us on
