Thank you very much for choosing our products, and please read over the Operating Manual and
keep it properly before the installation and use.
Warning
• The Electric Pump must be grounded reliably before use, and shall be equipped with
an electrical leakage protection device;
• It's strictly prohibited to touch the Electric Pump during operation;
• It's strictly prohibited to run the Electric Pump without water;
• It's strictly prohibited to run the Electric Pump with the valve closed;
• For three phase-motors with integrated thermal protector shut down due to overload
or overheating, it is NOT allowed to re-connect the power until motor cooling for more
than 10 minutes.
Electric Submersible Deep Well Pumps(hereinafter referred to the “Electric Pump”) include
SG(m), SE(m), SS(m), QJD series. SG(m), SE(m), SS(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.
QJD series is dry-type Electric pump 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 dry-type asynchronous motor is at the bottom of the Electric pump; adopting single
–ended mechanical seal and double-ended mechanical 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.
Electric pump is with high head due to its multistage impellers structure, Which are widely
applied in irrigation, deep well water lifting, tower water delivery, urban construction, and water
supply to industrial and mining enterprises.
I. Product Introduction
II. Operating Conditions
The Electric Pump shall be able to operate continuously and normally in the following
operating conditions:
1. The temperature of the medium does not exceed 40°C;
2. The pH value of the medium is 6.5~8.5;
3. The mass ratio of the solid impurities contained is not more than 0.01% and the particle
size is not bigger than 0.2mm;
4. The submersible depth of the Electric Pump in the water is 5~70m, while that of a QJD
pump is 5~20m.
