Garden pumps: Informations
Garden pumps are versatile pumps for mobile use or stationary installation. They are ideally suited for pumping water out of wells, watercourses or cisterns, for instance to irrigate your garden.
Their range of application also includes the filling or emptying of ponds, basins or reservoir tanks. The further pressurised delivery of the fluid furthermore allows the operation of irrigation systems - for instance sprinklers - and an efficient flushing of terraces and sidewalks.

The hydraulic system, however, must be vented in any case at the time of installation. This is done by filling the pump housing with water. Depending on the suction height of the water, this process may have to be repeated several times until the suction hose is bled out, i.e. completely filled with water with no more air left inside. For this purpose, a check valve is to be installed, preferably at the end of the suction hose.
If, owing to the great suction height of the water, filling the pump housing should require more than just one filling cycle, we recommend to prime the suction hose with water during first operation, too. As soon as the suction hose and the pump are bled out, the system will work as desired.
Please make sure that during operation no air will re-penetrate into the system through leakages or as a result of the absence of water. This is frequently the cause of operational malfunction, and it may even lead to damage to the pump for reason of overheating caused by dry-running.
Suction height and delivery height / pump head
Delivery height / pump head: Height difference between the water surface and the point of water withdrawal. The max. delivery height is referred to as "pump head".
Example: If a pump takes in water in five metres depth to lift it 15 m upwards, the delivery height totals 20 metres.
