Type description:
Take AT400QR350-45/1 as an example
AT: brand name
400: minimum well inner diameter that can apply to (mm).
The pump outer diameter can be neglect when pumping high temperature pool water
Q: submersible
R: hot water
350: flow capacity (m3/h)
45: head (m) 1: impeller
Application:
AT400QR series submersible pump for high temperature pool water is suitable for enterprises and public institutions hot water circulating, steel cooling water heat dissipation, the discharge, disposal and using of industry hot waste water, bath center, district heat supply, This pump is low noise, high efficiency and energy saving.
Technical Parameter:
Max. outer diameter: 360mm; Outlet diameter: DN250
Outlet connection parameter: M16×75, bolts center distance:325mm.
In order to install easily, we particularly have equipped with a matching flange (outer diameter: 360mm, inter diameter: DN250, thickness:20mm) consistent to the outlet.
Medium range:
1. Water temperature range: +5--+105
2. Allowable diameter of Solid in hot water: ≤1mm
3. Solid content (mass ratio): ≤0.01%
4. PH: 6.5-8.5
5. H2S content: ≤1.5mg/L
6. Cl- content: ≤400mg/L
7. The full set must be completely submerged into water in vertical position. While it will be inferior to the vertical form incling 45, horizontal use will lessen half of its service life.
Motor Parameter:
The length of extended cable: 2.5m. If you want to lengthen the extended cable, please inform 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(1050thermal 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.
4. Replacing the emergency pump quickly when the pump breaks down in harsh environment such as high temperature water tank or pool, or somewhere that are inconvenient for man to maintain.
5. Portable design with its small size and light weight. so you needn’t install bay bolt.
Supplys:
AT400QR series submersible pump for high temperature pool water (including the body and motor), 1 flange matching with outlet, M 16×75, 1 maintenance instruction, 1 conformity certificate, 1 packing list, wood external packing.
Color:
Regular color(without requirement): phthalocyanine blue chlorinated rubber paint suitable for machines working in non-aggressive water.
Corrosion-inhibiting Coating:
If the pump is used in corrosive high temperature environment:
1. Material such as stainless steel, tin bronze can be changed.
2. Brushing corrosion-inhibiting coating to prolong the service life if corroded not badly.(so it can work in the water environment of 10% sodium hydroxide or 10% sulfuric acid)
Friendly reminder:
For the customers’ convenience and our products’ quality, all the related products are manufactured by ourselves. The products detail 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.
