Inlet diameter: 50(mm)
2-2). General Description
ZX series self-priming centrifugal pump is a new modified centrifugal pump which is developed on the basis of absorbing domestic and overseas advanced technology of the same product and combining many years' design and manufacturing experience of our company.
It stands out the advantage of simple structure, convenient operation and maintenance, stable working, high efficiency, long life, good self-priming performance ect. It need not bottom valve in the pipeline. It just needs to have amount of liquid in pump for self-priming before starting pump. So it predigest pipeline system and improves working condition.
3). Application
3-1). It is used in environment protection, construction, fire protection, chemical industry, pharmacy, printing and dyestuff, brewage, electric power, electroplate, papermaking, washing for industry and mine, cool for device.
3-2). It can spray by turning water into little drop for farm, garden. Ect.
3-3). It is suitable for clear water, sea water and chemical medium with acid and alkali and mushy slurry(viscosity< 100 centipois, consistency for solid can not exceed 30% of total medium.
3-4). It can be used to transport slurry to compressor and filter with compressor and filter.
4). We warmly welcome customers all over the world come to us for high quality, best service and rock bottom price.

Q:Installation position of check valve for water pump
Check valves are generally installed at the pump outlet and exit control valve position. Self suction pump check valve installed in front of the pump, suction port better!Ordinary centrifugal pump check valve flange from the pump outlet flange is generally 300mm-500mm, its purpose is: when the pump is stopped, to prevent backflow of water to the pump body in the pipeline, resulting in the impeller reversal (generally positive rotation is more impeller impeller and shaft tight) that damage the impeller and pump head. Therefore, the height can not be too high, too high, there are too many water reflux, the consequences can be imagined.But there are self suction pumps, self suction pumps, check valves, flanges, pumps from the body, the outlet flange generally 1 meters to 1.5 meters.This is determined by the structure and working conditions of the self-priming pump. Self suction pump start, the pump is a gas at first, the main purpose is to exhaust the rotation of the impeller, will also play out some of the water, this time need to exhaust gas, water will need to return, if the valve is installed in the 300mm-500mm, then a lot of water can not return to the pump body (can also cause check valve is closed), effect of self suction pump work.Self suction pump check valve installed in the suction port of the pump better, this is not upstairs nine, brother said, must be installed in the export, this is wrong. Installed in the inlet of the purpose: it is time to stop the pump, there is generally no reversal of pump impeller, but to prevent the pipeline inside emptying (fluid inside the pipe can be in pipe) is beneficial to the self suction pump for a restart! Therefore, the self-priming pump check valve is best installed in the inlet pipe of the suction port.
Q:1.5 kW three-phase pump with 600 meters line, should match what big line?
1.5 kilowatts water pump distance 100 meters, with 2.5 square meters of electricity enough
Q:How to install circulating water pump for cooling tower?
This should be installed at the inlet of the cooling tower. The water at the outlet of the cooling tower is returned to the pool
Q:4--6 inch deep well pump head? How much per hour out of water?.
General agricultural pump 4-6 inches of lift at about 20 meters, the economic output of water is 140-200 cubic meters per hour
Q:Should the no-load power of the pump be equal to the rated power?
Manufacturers in order to make money, the nameplate marked "1200W", in fact, the maximum power of the motor, only 750W.
Q:What is the difference between a low pressure pump and a high pressure pump?
The specific speed of the high pressure pump is relatively smaller than the speed.Lift is not the same, the same flow, high pressure pump head high.Pump and shaft materials are not the same, high pressure pump raw material demand is higher, to be able to accept greater pressure and torque.The size is different, the pump body of high pressure pump is larger.Bearings can also be different, low pressure pumps are rolling bearings, and high pressure pump power, then some pumps are selected sliding bearings.The support method can also be different, the low-pressure pump is the pump foot support, but the high pressure pump can be the intermediate support.
Q:Relationship between pump voltage and lift?
In the case of power, W=F*S. That is, the work done per unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
Q:What are the conditions for the series and parallel connection of the pumps?
Parallel pumps: the pump is required to lift the same. This effect is to increase traffic.Pumps in series: requirements are similar to the flow of water pumps. This allows you to increase the total head and recommend adding small pressure tanks during the series connection.
Q:The problem of single phase pumps
The capacitor is broken. Change it.
Q:Pump head is too high what's the impact?
Measure the height of 50m, using 100m lift pump, the disadvantage is a waste of energy, such as the selection of 100m lift pump, flow of 10 cubic meters, motor power 5KW, with less than 5 0m lift pump, flow of 10 cubic meters, motor power 5KW, so that the lift ratio measurement height is greater than 10-20%, on the same pump motor power next, the pump head is larger, less water.If the height of 50m is measured, the pump with 100m lift head is used, but what is the influence of the flow rate on the pump or pipe?.
