Honourable mention, our smallest pump: Lowara Minibox

In contrast to the massive scale of the Calpeda NMS4, which can fill an Olympic-sized swimming pool in just over 5 hours, our smallest pump, the humble Lowara Minibox with the DOC 3 submersible pump is designed for more modest yet highly effective water management tasks.

With a flow rate of up to 230 litres per minute (L/min), which honestly is nothing to scoff at - the DOC 3 is ideal for handling domestic drainage needs, such as clearing small basements or utility rooms. T

o put this in perspective, while the Calpeda pump can quickly handle vast volumes of water, the DOC 3 would take around 7.5 days to fill an Olympic-sized pool. This stark difference in capacity highlights the DOC 3’s suitability for smaller, more targeted applications where precise, reliable water control is needed, rather than the large-scale industrial tasks managed by the NMS4.
