2 Description of the equipment
2.1 General characteristics
The electric motor driven pump (Fig. 1) is made up of a cylindrical motor housing [3]
inside of which is located an electrical motor [B]. The upper support [40] is completely
water-tight, and contains the terminal box for connection to the electric motor; the
waterproofing is guaranteed by the cover and by a series of seals [D]. Inside the oil
chamber/casing [4] is located the group of mechanical seals [F] that prevents the water
from passing to the motor.
On the main shaft [2], inside the oil chamber/casing [4] there is a keyed impeller [1],
made in high chrome content anti-wear materials. A lower wear plate [7], made with
the same material, partially closes the impeller inlet. Inside the strainer protection [50]
houses an agitator [10] that rotates and stirs the mixture of solids in the water to be
pumped.
