2. Pumps are almost fully manufactured of stainless steel.Most parts of the pumps are made of stainless steel. Even the piston is covered in stainless steel, which substantially extends its life duration.

3. Reduction of the pumps’s diameter to 49mm. his gives the possiblity to use the pump in a 2“ well (50,80mm) and provides therefore an innovative alternative to the 2“ hand pump

4.Improvement of the valve with high quality material. This results in a improved impermeability of the valve and extend the life duration.

5.Electronic control devices are inserted under the pump in a poured case made of stainless steel. No humidity problems for electric control devices anymore.

6. A foam filter is inserted serial.Therefore the pump can be used to impure water, because now the pump is protected against sand and other particles.

7.Improved handling for servicing and reparation. Through reduction of possible installation errors, the pump is more user-friendly than its predecessors.

8.More accessories. From now on silicone tube, main spring,non-resinous oil, foam filter, 3 mm and 8 mm hexagonal key are provided in the box.
