Starting

7.1

Preliminary information before starting

The starting must be performed by qualified and skilled personnel. The protection must cover all rotating components. Ac-
tivate all security procedures and monitor the efficiency of the protections. Isolate the area within a radius of 2 metres and
avoid access to unauthorized persons.
Never run the pump without water; dry functioning, even brief, can destroy the hydraulic components.
7.2

Lubrication

The pumps described in this manual are supplied without lubricating oil and before starting it is necessary to proceed with oil fill-
ing. Refer to tab.1 for quantity and type of oil.
7.3

Starting of T, TK, MB pump series

- Carefully fill the pump body and the suction pipes checking that no air is trapped inside. If possible turn the shaft manually maneuvering the
coupling.
- Start the pump-motor unit with gate valve slightly open.
- With running pump gradually open the gate valve to obtain the desired operating performance.
- On pumps equipped with gland packing, make sure that the packing leaks approx. 20 to 60 drops per minute to allow adequate cooling and
shaft lubrication. If necessary, adjust the flow slowly and progressively loosening or tightening the packing nuts (this adjustment must
be performed with running pump). Be careful not to touch moving parts.
7.4

Starting of T0 pump series

- Carefully fill the pump body and the suction pipes checking that no air is trapped inside. If possible, turn the shaft manually maneuvering the
coupling.
- Start the pump-motor unit with gate valve slightly open.
- With running pump gradually open the gate valve to obtain the desired operating performance.
7.5

Starting of T0A pump series

- These pumps could be used even without footvalve. Anyway, the use of a grid (with max. 10 mm mesh) is recommended.
