Type Description:
Take AT250QJR80-210/7 as an example
AT: brand name
250: minimum well outer diameter that can apply to (mm)
Q: submersible
J: for well use
R: hot water
80: flow capacity (m3/h)
210: head (m); 7: impellers
Application:
AT250QJR series submersible pump for hot water is suitable for enterprises and public institutions such as bath center, district heat supply, power generation, underground hot water lifting. Different specifications and types provided for different wells. This pump is low noise, high efficiency and energy saving.
Technical Parameter:
Maximum outer diameter: 234mm. Outlet diameter: DN125
Outlet connection type: 8 bolts M14×60 threaded studs. Center distance:180mm.
In order to install easily, we particularly have equipped with a matching flange (outer diameter: 178mm, inter diameter: DN125 and thickness: 16mm) consistent to the outlet.
Medium range:
1. Water temperature range: +5℃--+105℃
2. Solid content (mass ratio): ≤0.01%
3. PH: 6.5-8.5
4. H2S content: ≤1.5mg/L
5. Cl- content: ≤400mg/L
6. The full set must be submerged into water completely in vertical position and the model must be matched with the well diameter.
Motor Parameter:
The length of extended cable: 3m. If you want to lengthen the extended cable, please phone us in advance. The submersible motor is lubricated by clean water. It must be filled with clean water, or its service life will be lessen. If you forget filling, the motor will be broken.
Motor protection level: IPX8
Electromagnetic wire material: high temperature resistant and water proof.
Power Source:
Rated voltage: 380v (±5％) Frequency: 50Hz(±1％).
If you need special voltage or frequency, please inform us in advance.
Materials:
Impeller: Cast iron HT200, or tin bronze, such as ZCuSn3Zn8Pb6Ni1
Pump bowl: Cast iron HT200, or stainless steel, such as 2Cr13.304
Pump shaft: Cold-drawn steel with chrome plating, or stainless steel 2Cr13(1050℃thermal refining, enhancen torsional moment)
Motor Seal: Rubber O-ring seal, mechanical seal
Motor regulating sleeve: rubber
Advantages:
1. Easy installation
2. Low noise, high temperature resistance, long service life.
3. Fully operating in water avoiding entering air.
Supplys:
AT250QJR series submersible pump for hot water (including the body and motor), 1 flange matching with outlet, 8 bolts M14×60, or equipped with related outlet (in order to install convenient for customer)1 maintenance instruction, 1 conformity certificate, 1 packing list, wooden external packing.
Color:
Regular color(without requirement): phthalocyanine blue (chlorinated rubber paint) suitable for machines working in non-aggressive water.
Anticorrosion Coating:
If the pump is used in corrosive high temperature environment:
1. Material such as stainless steel, tin bronze can be changed.
2. Brushing anticorrosion coating to prolong the service life if corroded not badly.
Friendly reminder:
For the customers’ convenience and our products’ quality, all the related products are manufactured by ourselves. The products detailed information are as follows:
a. All kinds of lifting pipes including high-frequency welded pipes (dia.25mm-500mm); Connection type: flange connection, screw connection and clamp connection. They are made accurately by machine tools.
b. Pipe clamp: the length is 50mm-500mm (we can produce the other different spans according to your requirements).
c. Wellhead devices: return flow wellhead instruments (applied to ground source heat pump), general pump seat (we have innovated and designed this kind of pump seat by replacing the original iron castings with steel plate welding; the cable lead-in hole has also been improved by substituting the U hole for middle lead-in hole, thus making more convenient for the customers.)
d. Desander: avoiding blocking and polluting by sand in water. And it contributes to long service life.
e. Related products: submersible cable, starting cabinet, frequency conversion cabinet, transformer, electric generating set, etc.
f. According to the conditions on the spot, we also supply the design proposals about pipe network, tank and installation.
