Product Description:

Product Introduction:
     This pump integrates self-priming and non-jamming blowdown, which is unnecessary for mounting  the bottom valve and guiding the water like the general self-priming clear water pump and also can pump the filth containing big solid blocks and long fibers,sediment,waste ore, impurities,excrement and all engineering sewage.Therefore, it can alleviate the worker′s labor intensity completely and also is easy for use, move and installation with seldom maintenance and stable performance.

reliable performance
seldom needs maintenance

install easy

reducing workers′ labor intensity


be integrated with self-suction and drainage


doesn′t need to fix a foot valve or fill inducting water as common clean water self-suction pump


international standard


ow noise

Q:Fire pump room is required to set up water pump control room?
What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control
Q:Pump pumping small is what happened?
Multi pass is self-priming pump, right? Check that the water inlet pipe is connected. If there is a little leakage, the lift will not be high. If the submersible pump, impeller pump or screw pump, they do not have irrigation. If it starts small and then flows, it may be that the water in the well is not rising so fast, that is to say, the water is poor. This happens, too. If it starts small, which may be the well did not hit the good position. Suggest a little more. Is it used in your house? Still have other uses?. For home use. A bucket of water is enough.
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
Water pumps are generally centrifugal pumpsThe circulation pump depends on what kind of liquid it is circulatingGrease is generally gear pumps
Q:Yang Chengtai big, the pump power is too small, the water pump will be bad?
Related to water pump structure, when the pump head is higher than the rated pump head, the current will increase, the water discharged from the pump impeller, back to the inlet of water from between the impeller and the casing exceeds the rated value, if it is a high lift pump, clearance between the impeller and the casing is small, the water pump current increases with increasing lift, current too much faster than the rated value, the motor will burn; if it is a low lift pump design, when the clearance between the impeller and the casing of the strict requirements, and even some of the water pump, the outlet is blocked, the pump will not burn. The drinking water pump used on the table, generally used non-toxic latex diaphragm pump, the head is too much, will damage the diaphragm part, the motor because the circuit has protection, the motor is not easy to damage. Generally do not risk good, according to the actual situation, select the appropriate lift, suction pump.Yang Chengtai large! If the pump power is too small! The pump will break! But not necessarily bad, mainly determined by the pump structure.
Q:My fish tank pump is deep enough, it doesn't bubble up. Without oxygen supply, but it can filter. Does it damage the pump itself?
The easiest way is to pump a bottle of mineral water under the pump. It's too long to cut off some of it.Bottle to the end, the pump can beat oxygen on the line. A hole is under the bottle.
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
May not。Design is in accordance with the "two prepared" design, opened two units, has been able to meet the water supply requirements. And the electrical control parts are in accordance with the opening of two units, has been unable to meet the opening of 3 power distribution needs. The standby pump is only replaced when the running pump is out of order or needs downtime to maintain the water supply.
Q:Water pump maintenance what should be maintained?
1 by sound to determine whether the bearing is good. If the sound is abnormal, replace the bearing.2, check whether the impeller is worn, if worn, will affect the flow, lift, efficiency, need to be replaced.3, check whether the mechanical seal can continue to use, can not be used, need to be replaced4, check the oil tank is missing oil, such as lack of oil to the appropriate location.
Q:How to connect the household pump capacitor?
220V has two lines (lines 1, lines 2)There are two lines of capacitance (line 3, line 4)There are three lines on the motor (line 5, line 6, line 7)3 11 52 64 7That's plain enough. To change the turn, change any two of the 5, 6, 7, three lines
Q:What does the temperature range of the pump mean?
The range of temperature is less than 135 degrees Celsius, which means that the range of use shall not exceed 135 degrees celsius. Refers to the temperature of hot water, high pressure steam boiler inside the water temperature is more than 100 degrees Celsius, your pump is a high-pressure high temperature water pump, generally used for steam boiler or high temperature waterway system. For reference only.
Q:When the pump is connected in parallel, will the head and flow change?
Depends on how you do it.If you have a pump, the original network is the same, you add a pump, the result is the head and flow increases, the efficiency also changed, increase the number of head and flow, depending on the network characteristics, network characteristics such as steep increase, economy is also poor, which is not recommended. In fact, the actual flow of two pumps plus the actual lift equal, the problem is that the head, flow point of operation has changed.If it is new design, according to the required flow calculation of the required head, according to the head, half of the flow to select the pump, that is, two pumps flow volume, lift equal.
