HYDRAULIC CONNECTIONS
Check that the suction line does not exceed the maximum height of 1.5 m from the tank bottom.
Unscrew the pipe-wrench nut and remove the two protective caps from fittings (in the case a
pump head needs to be removed, it is recommended to reuse the protective caps, to prevent any
leakage from the pump body).
Note:
If the product to be dosed is sulfuric acid (10% max concentration), previously remove any
water from the pump and use polyethylene pipes.
All operations to tighten the pipe connections of the pumps must be done by hand, without using
any tools (e.g. pliers squeeze tube), to avoid damaging the hydraulic connections.
Warning!
Before performing any kind of operation on the pump, carefully read the HSDS
of the chemical to be dosed, in order to define the proper behaviors to be followed, and
the personal safety equipment to be worn.
Suction Line
(also see drawing)
1.
Unscrew the fixing nut of the connector located
on the bottom left side of the pump head and
marked in the figure with an incoming arrow.
2.
Cut the transparent PVC Crystal tube to the correct length.
3.
Insert the fixing nut on the tube.
4.
Mount the tube on the conic tube-holder of the suction
connector, pushing it until it reaches the stop collar.
5.
Fix the tube by screwing the fixing nut onto
the suction connector of the pump head.
6.
Locate the transparent PVC tube inside the tank
and/or the suction lance.
7. Unscrew the fixing nut of the foot filter.
8. Insert the fixing nut and the tube-wrench on the tube.
9. Mount the tube on the conic tube-holder of the foot filter
connector, pushing it until it reaches the stop collar.
10. Fix the tube by screwing the fixing nut onto the connector of the foot filter.
11. Screw the foot filter onto the suction lance (if used) and/or locate it in its working place.
Notes:
•
The foot filter must be located at a minimum distance of 5 cm from the tank bottom.
•
If a dense product is dosed, it is recommended to remove the small
inside filter from the foot valve, in order to facilitate the suction.
