With the Gardena 1730-20 preliminary filter, you protect your garden pump or booster pump against abrasive sand and debris. When drawing water from open ponds, wells, or rainwater barrels, this pre-filter captures impurities before they reach internal components. This prevents clogging, reduces downtime, and extends the operational lifespan of your pumping system. Built for a high flow rate of up to 6000 l/h, it connects directly between your suction hose and pump via the 1" male thread. Whenever maintenance is required, simply remove the washable filter insert, rinse it clean under running water, and reinstall it for reliable operation.
