Practical insights – from pump selection to operation.

Select the correct circulation pump rather than oversizing it
Determine the flow rate and head accurately, avoid applying surcharges more than once, and check the operating point using the quick design tool, PumpSelector 6 or the replacement chart.

Adjusting a high-efficiency pump correctly
Proportional pressure, constant pressure or constant speed: which control mode is suitable for which heating, air-conditioning or domestic hot water circuit – and what the cost is of setting the Characteristic curve too high.

Draining construction sites and protecting them from flooding
Keeping excavation pits dry, lowering the water table, warding off flooding: the technical considerations for construction and wastewater pumps.
