Impeller:Cast iron HT200,or tin bronze,such as ZCuSn3Zn8Pb6Ni1

Pump bowl:Cast iron HT200,or stainless steel,such as 2Gr13.304

Pump shaft :Cold-drawn steel with chrome plating,or stainless steel 2Gr13(1050 thermal refining ,enhancent  torsional moment)

Motor Seal:Rubber O-ring seal,mechanical seal

Motor regulating sleeve:rubber


The deep well water pump unit is composed of the motor and pump together which is placed in the bore well by connecting the motor cable with the power supply which drives the impeller rotating.it is simple and small light-weight structure easy to maintain.it runs in a good condition and performs well.

This is new highly efficient machine and low cost for water supply.It can be used for drainage in mines,a city's water supply,clean water and irrigation and portable water and animals areas lacking water.

8.Structure feature

 pump:The pump is installed on the upper part of the pump units.It's centrifugal and has water lubricated bearing mounted with the motor shaft by a joint.

There is a check valve on top of the pump which could prevent rapaid inverse rotation from backword flow.The pump unit should be immersed below the dynamic water lever when in using.

motor:The motor is installed under the pump.

It is a water filled in hermatical structure.The stator windings are water-tight and PE insulating and multi-layers are covered with nylon.

The motor bearing is water-lubricated.The inner motor contains clean water to cool the water body and the bearing.

The rubber diaphgram adjusts the pressure change caused when temperature rises.

There is a sand resistance system in the upper part of the motor.
