Ensure in delivery that:

- All pipes and fittings are adequately dimensioned to reduce pressure loss and to withstand the maximum operating pressure of the pump.

- A gate valve is fitted to regulate delivery flow.

- The suction pipe has not narrow bends and diameter variations.

- Anchorages and supports to prevent damages and possible breakage of delivery flange are properly secured.

Installation of T0, T0A pump series

Pump coupling must be performed only when tractor is off. Make sure that the tractor cannot be accidentally started acci-

dentally. All T0 and T0A pumps can be either mounted on permanent stations or on mobile trolley.

The cardan shaft should be connected with an alignment angle less than 10° (fig. 7). Suction and delivery pipes must be

correctly mounted and not subject to stress during pump operation. Also refer to paragraph 6.2.

In T0F and T0FA execution (fig. 8) these pumps are fitted for direct coupling to the p.t.o. of tractors. For installation proceed as fol-

lows:

- Lift the pump until the p.t.o. is aligned with the pump coupling; slightly rotate the coupling to meet the splines and push the pump towards the

p.t.o.

- Pull the coupling external ring towards the pump, overcoming the return spring resistance; now push the pump towards the p.t.o. to find the

foreseen coupling position.

- Release the ring back to its original position. Check that installation is made correctly by pushing the pump forward and backward: the pump

must remain firmly anchored to the p.t.o.

- The pump will result radially swinging on the p.t.o. Complete anchorage is made by hooking the two chains at the ends of the traverse anchor

bar fixed on pump support. Chains prevent the pump to rotate further to the p.t.o. motion.

- To grant a firm anchorage it is important to find suitable points/positions on the tractor where chains can be hooked. On the other hand, chains

shall be long enough to reach any anchorage point under or above the p.t.o.

- If anchorage points are under the p.t.o., the chain with the spring will be at the left of the pump. Of course, if anchorage points are above the

p.t.o., the chain with the spring will be at the right of the pump.

- Use the accessories supplied with the pump (elbow, connection and foot valve) to connect the pipes.

- Refer to paragraph 6.2.
