1.1 Pump Applications
The deep well electric pumps (hereinafter referred to as the “electric pumps”) include SA(m) series electric pumps. This
series of electric pumps are with high head due to its multistage impellers structure, which are widely used in irrigation,
deep well water lifting, tower water delivery, urban construction, and water supply to industrial and mining enterprises.
1.2 Pump Introduction
SA(m) series are oil-filled being composed of two parts i.e. pump body and motor. Pump body is with multistage centrifugal
impellers lying upper of the Electric pump, a single-phase or three-phase asynchronous motor is at the bottom of the
Electric pump; adopting single-ended mechanical seal as dynamic seal in the motor, and at the place of sealing of each
fixed spigot is an O-shaped rubber seal ring used as the static seal.
