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.
