Introduction:HSP type chemical mixed flow pump is a type of pump between centrifugal pump and axial flow pump, which can economically and effectively transport high flow, low head, pure or containing certain particles, chemically neutral or corrosive liquids (strong corrosive liquids need to be specified). The pump has high performance and low energy consumption, with an average energy consumption throughout the entire functional range. It can be started under closed valve conditions without overloading the motor. The overcurrent section is large, not easy to block, the structure is tight, and the service life is long.
HSP type chemical mixed flow pump commonly uses 0Cr18Ni9, 1Cr18Ni9, 0Cr18Ni9Ti, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, 40Cr, Monel, 1Cr18Ni12Mo2Ti, Ti (titanium), 00Cr17Ni12Mo2Ti, Hastelloy B alloy, 0Cr25Ni20, F5 series alloy, 20 alloy steel, Made of materials such as 0Cr25Ni6Mo3Cu2Mn2Si, the shaft seal adopts a double end mechanical seal, and users can choose according to actual working conditions.

Explanation of pump model meaning:
Structural features:
Mixed flow pump is a type of "pull-out" structural pump, which does not require dismantling the pipeline connected to the pump body when inspecting and disassembling the impeller and shaft seal. Equipped with precision machined pump shafts, bearings lubricated with thin oil, and protective shaft sleeves in the packing box cover. The legs of the pump body can withstand any load from the pipeline and directly transmit it to the foundation. In this way, the rotor will not bend due to the load borne by the pump, ensuring the optimal service life of the bearings.
Due to the larger overcurrent area, it reduces blockage. The rotation direction of the pump, when viewed from the drive end, is clockwise. The power drive can be either an electric motor or an internal combustion engine. The pump device can be equipped with a complete air release device, which is beneficial for the exhaust of the suction pipeline.
Performance parameter table
Users should pay strict attention when using it
1、 Lubricating oil should be added to the bearing box, and the oil level should be controlled at the middle level of the oil window.
2、 Before driving, manually rotate the coupling to check for any jamming during installation. If there are any scratches or abnormalities, they should be eliminated.
3、 Before starting, connect the coolant flushing solution first. When stopping, stop the vehicle first and then turn off the coolant flushing solution.
4、 The cooling flushing fluid must be clean, non scaling soft water, so newly installed pipelines and storage tanks should be flushed clean. Prevent solid substances from entering the mechanical seal and affecting the sealing effect and service life. Water that is prone to scaling can block the cooling flushing fluid pathway. It will also affect the effectiveness and lifespan of the seal.
5、 The use of condensed water as a sealing flushing solution is ideal, with a temperature below 85 ℃.
6、 The pressure of the cooling flushing liquid is 0.1~0.3 MPa, and the flow rate is 0.63 m3/h. If the flow rate is too small, it will affect the service life of the seal.
Troubleshooting methods and ordering instructions
fault |
reason |
solution |
Export without displacement |
1. The pump is not filled with liquid 2. There is air intake in the suction pipeline 3. Installation height too high, input hot or easily vaporized medium 4. Turn back 5. Require the head to be greater than the head |
1. Recharge liquid 2. Repair the pipeline 3. Reduce the installation height of the pump 4. Change direction 5. Choose a new pump |
Insufficient traffic |
1. The bottom valve is too small 2. The suction pipeline is not deeply immersed in the liquid, and air is brought into the pump 3. The suction pipe diameter is too small and blocked by debris 4. The discharge pipe is too thin, and the pipeline loss is too small 5. Impeller wear |
1. Configure large bottom valve 2. Increase immersion depth 3. Replace the thick tube and remove any debris 4. Replace the discharge pipeline 5. Replace the impeller
|
High vibration noise |
1. The pump is not concentric with the motor shaft 2. Pump shaft bending 3. Loose impeller nut 4. There are debris entering the pump 5. Bearing damage |
1. Calibrate the pump and motor axis line 2. Remove the straightening or replace the shaft with a new one 3. Unload the pump and tighten the impeller nut 4. Unload the pump and remove debris 5. Replace bearings |
Bearing overheating |
1. Oil cup without oil 2. The pump shaft and motor shaft are not aligned |
1. Keep going 2. Two axis alignment |
