End suction centrifugal pump
ISW Series End Suction Pump with single-stage and single-suction pipeline are designed by technicians uniting domestic excellent waterpower model, adopting the specification data of IS model centrifugal pumps and the differences of temperature and media on the basis of Model ISG. The series of these pumps have high-effective, voice-saving and reliable performance.
Single stage End Suction Pumps Characteristics
1. The structure is horizontal with the same dimensions of inlet and outlet calibers in the same centerline; It can be installed in the pipeline as valve with compact, shapely, small area and low construction cost. It also can be used out of the door if it is installed with protective cover.
2. Impeller is installed on electrical machine's extended shaft with short axial dimensions and impact structure. Pumps are matched in reason with electrical machine's impellers. Radial and impeller load are well balanced during the process of transporting which makes sure it can go steadily with small vibration and voice-saving.
3. Axial seal adopts machinery sealing or the combination of machinery seal and titanium alloys sealing ring, medium-sized heat-resistant machinery seal and adopting horniness material, wearable seal in order to protract the using time of machinery seal.
4. In the part of installing and repairing, no need to tear down pipeline system. The rotor parts can be easily drew out if only taking down the pump nut.
5. Operating style can be decided by requirement on runoff and height.
6. According to the position of pipeline to decide to choose the installing method: Upright and square.
ISWB chemical centrifugal pump stainless of steel and explosion-protection applies to transport flammable chemical liquid.
1. Suction Pressure≤ 1.0 MPa, or the Max Working Pressure≤ 1.6 MPa, namely Suction Pressure uniting Height ≤ 1.6 MPa, Testing Static Pressure of pump is 2.5 MPa; Please give clear indication of system's working pressure. Please note it if the system's max working pressure is larger than 1.6 MPa
2. Working Temperature<40º C, relative humidity<95%.
3. The whole solid's volume of Medium should smaller than 0.1% of unit volume, granularity <0.2mm.
If the using media contain tiny solid, please indicate when ordering, or the suppliers can adopt wearable machinery seal.
1. Check the fasteners in the system loose or not, and interval channel is walled up by eyewinker or not in order to protect the pumps operate damage the impeller and casing.
2. The weight of the conduit should not on the pumps in order to prevent the pumps' distortion.
3. Make sure to screw down the holding down bolt to prevent the shock, influence the specification of the pump.
4. In order to make fix convenient and safe usage and valve sauces should installed in the pump pressure gauge on the door of the nearby to make sure the normal operation under the rated height and range of flow and to make pump's life span longer.
5. Pump's shaft is bolded, impeller should have no grating and launched instable.
6. Pump's installation of the rigid link in and soft link. (please see the linking style)
1. Maintenance during operating
(1) The inlet channel should be filled with liquid, prohibit the long-term operating in the condition of cavitations.
(2) Check the machine's electric current data regularly to make sure it doesn't exceed the rated current data.
(3) Be sure the machines are checked after long-time usage as mechanical wear may make the machine's voice bigger and concuss more fiercely. If it needed, the damageable parts or bearings can be replaced. The major repairing period of the machine should be one year.
