IV. General Design of a 1GA/2GA Pump

Design

The pump is a submersible, electric motor-driven product.

1. Impeller

The impeller has a cutter mounted at the inlet which grinds solids.

2. Shaft Seals

The pump has two mechanical face seals - one inner and one outer, with an intermediate
oil housing.

3. Shaft

The shaft is delivered with the rotor as an integral part. Shaft material: stainless steel.

4. Bearings

The support bearing of the rotor consists of a single-row ball bearing. The main bearing
of the rotor consists of a two-row angular contact ball bearing.

5. Oil Housing

The oil lubricates and cools the seals and acts as a buffer between the pump housing and
the electric motor.

6. Motor

Squirrel-cage 1-phase or 3-phase induction motor.
The motor can be started by direct on-line or star-delta starting.
The motor can be run continuously or intermittently with a maximum of 15 evenly
spaced starts per hour.
