APP Pumps manufacture the RS32EA and RS40EA automatic submersible pumps, designed specifically for shallow water control where space is limited. These compact submersible pumps are ideal for applications where water needs to be kept at a consistently low level, even where a traditional sump is not available.
Both the RS32EA and RS40EA are automatic submersible pumps, compact and ideal for use in narrow sumps or for draining basements. Shallow water level control is easy with the miniature float switch. The protected mechanism is housed carefully inside the chamber away from any obstructions.
If a sump is unavailable, which can be the case with preformed vessels, concrete channels or lift shafts, then the narrow operating range of the pump is ideal:
We are proud to offer a 2-year warranty on APP water pumps.

Each type of float switch has its advantages and is best suited for specific scenarios. The choice of float switch depends on factors such as the type of liquid, space constraints, required accuracy, and the pump's intended application.
Layflat hose is very affordable but can kink. Depending on your use, you may be better using a reinforced suction delivery hose for your needs.
Suction delivery hose is ideal for pumping up stairs or over obstacles.
Jonathan Martin explains the differences to help you choose which hose is best for your scenario.
With many pump specifications, you will often see a graph, with a curve or a series of curves depending on additional models, these are called pump curves. The pump curve describes the relationship between the flow rate, and the head of the pump.
The head shows how high pumps can pump vertically, with horizontal pumping, we normally use the rule of 10 metres distance will equate to 1 metre in vertical pumping. Always aim to use a pump towards the centre of the curve, as this is the optimal way to use a pump. Using a pump on either edge of the curve will put a lot of stress on the pump, which could cause it to wear out sooner.
