1. General

The purpose of this manual is to provide the necessary information for the installation, use and mainte-
nance of the pumps.
The user should read this manual before using the pump.
Improper use could damage the pump and cause the forfeiture of the warranty coverage.
When asking our sales and after-sales services for technical information or spare parts, please indicate
the model identification and construction numbers found on the nameplate.
The following instructions and warnings refer to the standard model; for any variations or characteristics
of the special versions please refer to the sales contract.
For any instructions or situations not referred to in this manual or in the sales documentation, please con-
tact our sales service.

2. Preliminary inspection

After unpacking the pump make sure that no damage has occurred during shipping.
Should the pump be damaged, please inform our agent within 8 days from the delivery date.

3. Applications

chemical agents in many civil, agricultural and industrial applications. The EQ series electric pump can
also handle moderately aggressive liquids.
