Product Description:


Horizontal, radially split, single-stage volute casing pump in back                                                          pull-out design to ISO 2858, with zero-leakage hydrodynamic shaft seal,                                                         with radial single-entry impeller. Applications: handling aggressive                                                            fluids in the chemical, petrochemical and food industries, in refineries, paint shops, heavy oil and coal upgrading plants.    
Particularly suitable for applications where double-acting mechanical                                                        seals cannot be used because there is no appropriate barrier fluid, and                                                         if no flushing liquid is available to feed the gland packing or if the flushing liquid must not mix with the fluid pumped.

Q:What are the main performance parameters of hydraulic pumps?
Main performance parameters of hydraulic pump:1. Hydraulic pump pressureHydraulic pump operating pressure is the pump (or motor) in actual work output (or input) oil pressure, determined by the external load.Rated pressure refers to the maximum pressure under continuous running in accordance with the test standards under normal working conditions. The size of the pump is limited by the service life, and the service life of the pump (or motor) will be shorter than the design life if it exceeds the rated pressure. When the work pressure is greater than the rated pressure, it is called overload.
Q:What is the pumping property of concrete?
Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.
Q:Double floor sewage pump circuit diagram of a small problem
Q 2, SA and SS are select switches, and different positions indicate the same difference between the two nodes. SA hits the left position 13, 14 to connect, hits to the right position 21, 22 to connect. SS hit the middle position, 5 and 6 turn on, 7 and 8 turn on; hit the right position; 1 and 2 turn on; 11 and 12 turn on; hit the left seat; 9 and 10 turn on; 3, 4 turn on.
Q:Fire pump and shower pump flow head selection, high resolution.
3, larger than 25000, the minimum water consumption of indoor fire hydrant is 20L/s4, the minimum water consumption is the flow of a fire hydrant.
Q:How does the centrifugal pump pump and cut the pump?
Check the motor, pump and fasteners in good condition; whether the lubricant is added or not;Disc dynamic coupling, whether or not stuck phenomenon;Open the inlet valve, remove the gas in the pump or pump the gas out of the pump;
Q:How many millimeters is the diameter of the water outlet of the four inch pump?
Here is a 4 inch inch, not rural, 1 inches =25.4 mm, 4 inches is approximately 100mm, with DN100 pipeline.
Q:How should the water pump be installed?
(8) check the suitability of the foundation and whether the size of the foundation corresponds to the size of the pump.(9) find the position of positive pump and motor, pump set and anchor bolt and the inlet and outlet flanges, to ensure that the flange torque of the pump conforms to the standard. Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition. It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
Q:What is the Rhodes pump?
Work principle editorRoots-type pump is a vacuum pump without internal compression, usually compression ratio is very low, so high and medium vacuum pumps need pre pump.A vacuum pump for pumping air by pumping a gas by the simultaneous rotation of a pair of lobed rotors in a pump cavity and a reverse rotation.Roots vacuum pump is a mechanical vacuum pump with a pair of synchronous and high-speed rotating sole shaped rotors. The pump can not be drawn out separately. The front stage needs to be equipped with an oil seal and a water ring, etc. it can be discharged directly into the atmosphere.
Q:What is the name of the day pump and ground pump? Specific introduction
Day pumpDay pump is called "day pump", the main reason is that it can deliver concrete to a certain height, make up for other concrete pump transportation shortage. Compared with other concrete pumps, the pump has its own boom, and the concrete can be transported without the use of artificial cloth. It is very convenient for use. At present, China's longest boom pump is 101 meters, which means that 101 meters under the floor can be completed with the help of day pump concrete delivery. In addition, the pump is equipped with a chassis, so compared with the ground pump, it can walk independently, moving very convenient, you can quickly move from one site to another location.
Q:Rules for operation of centrifugal pumps
5, before you stop, you should gradually close the outlet valve, then turn off the power supply.6, with the check valve line, in ensuring the check valve intact, without closing the outlet valve, check the pump cavity, no air can be directly switched on.
