It's no secret that today's UK caravans are designed by idiots & assembled by chimpanzees on work experience courses!
There are so many simple things lacking in modern vans. We hope
to fill a few of the gaps!
Aquapump is a smart pump controller designed by ACTUAL caravan users. It's the kind of thing that should really be included when you buy a caravan.
Aquapump is a multi-purpose pump controller for caravans. It
uses a microcontroller to manage 12v pumps.
This might be your fresh water pump or your heating pump (for example).
It is designed to do four different things:
Caravan water pumps don't like running dry. They get hot &
Aquapump detects when your fresh water is running dry & disables the pump before it is damaged.
It's simply spliced into your existing pump wiring.
We've heard stories about certain heating pumps starting
up rather noisily...
Aquapump can kick your pump into action straight away or turn it on gradually, and quietly over a few seconds or minutes.
The rate is set by turning the knob on the board. Once again, it's simply spliced into your existing pump wiring.
Aquapump uses PWM (Pulse Width Modulation) to control motor/pump
speed. This might be useful if your heating pump is consistently
It probably doesn't need to run flat out all of the time so you can turn it down a little. Because PWM is intrininsically efficient this can also help your battery if you're not on EHU.
Aquapump can also be used to control the fan speed in blown air heating systems. It can also be used to control the brightness of lights
This product was originally designed for Aquawaste senior, a
bespoke design to pump waste water 100ft away & uphill!
You can make your own Aquawaste senior if you're technically inclined. In this mode Aquapump drives a pump sitting in a receiving vessel (probably a bucket) and waits for water.
When water is detected it starts work and empties the vessel, then switches itself off. Obviously you need a 12v submersible pump & a source of power. The original Aquawaste uses a separate SLA battery.
A none return valve is also required for uphill use.
The PCB is designed to fit a watertight enclosure. Details are
provided on the Aquawaste page.
