Can I use a pump for Dirty water also for clean water applications?
If you need a pump to be used for clean and dirty water, then D-DW is suitable for both applications. This is due to the adaptable filter in 2 positions.
Model: D-DW COMBI
Can I use the pump with liquid containing gravel and stones?
The maximum particles dimension is refered to soft materials. Gravel may damage the hydraulic part of the pomp.
Model: D-DW COMBI; D-DWP
Where can I install the pump for gardening applications?
All surface pumps must be placed in a dry and clean space, not exposed to the rain and atmospheric agents.
Model: D-JET; D-BOOST; D-EBOOST; D-BOOSTi; D-MULTI; D-EMULTI
Can I place the pump in a non-airy space?
Yes, all Tallas pumps are designed with a water cooling engine. This means they can be placed in tiny and stuffy spaces.
Can I use the pump for drinking water applications?
Yes, all the surface pumps are suitable for drinking water applications. They are all ACS certifyed (French drinking water certification).
Model: D-JET; D-BOOST; D-EBOOST; D-BOOSTi; D-ECONCEPT; D-MULTI; D-EMULTI
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).
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.
Model: D-DW COMBI; D-CW; D-SUB; D-DWP
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.
Model: D-EBOOST; D-BOOSTi; D-BOOST; D-ECONCEPT; D-EMULTI; D-ESUB
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).
Can I connect a check valve to pumps for dirty water?
Check valves are not suitable for dirty water applications: they would be soon clog up by the dirty liquid.
Are Tallas pumps frost resistant?
No, pumps are not frost resistant and they need to be protected. Also, they are equipped with a discharge tap which allows the pump to be emptyed.
