How long could a pump work without pumping water?

All pumps should NEVER work without liquid, otherwise they would be damaged. Electronic pumps are equipped with the anti dry-run function. Automatic pumps are equipped with sensors in order to prevent the dry-run (through out the floatswitch).

Model: All

What happen if I keep the floatswitch in vertical position?

If the floatswitch is blocked in vertical position the pump works in manual mode: it works until it is connected to the electrical plug. In this case the pump is used without any protection against the dry-run, so if there is no liquid, the pump will be damaged.


Can I use pumps to increase the pressure?

Pressurization pumps (pumps with tanks or pumps with electronic) may be used for increasing the water pressure. It is important to remind that the max operating pressure of pumps is 6 bar.


Can I use Tallas pumps in continous?

Tallas pumps have been developed neither for applications in continous or for applications with frequent starts/stops. Typical Tallas applications are those including 1 start/stop per day, with an expected lifetime of around 250’000 starts (depending on the liquid type).
