Product Description:

 Bare Shaft End Suction Centrifugal Water Pump for Firefighting

1.Bare Shaft End Suction Pump for Firefighting

End Suction Centrifugal Pump complies fully to the European Standard BS EN733 / DIN24255 of performance and dimensions. They are used for pumping clean water or liquids similar to water, achieving wide application on plants, mines, city water supplies, air-conditioning coolers, firefighting system and irrigation. Pumps of the same model have different performance levels basing on different diameter after impeller trimming. Overall the whole series, there are only four sizes of shaft and five of bearing housing. As long as their bearing housings are of the same size, different pumps can interchange chief parts such as shaft, shaft sleeve, shaft seal, impeller nut, etc.

End Suction Centrifugal Pump is also very easy to be installed and maintained. Back pull-out design, driven through flexible coupling, so that pump casing and motor can remain in position while other spare parts are removed.

Q:Metering pumps related matters
Rotate to stroke length 100% position. This allows the kit to rotate to the back of the drain hole and align the bottom of the pump. Adjust the hydraulic end and diaphragm to the proper position during the pump operation.The duration of the pulse may not be long enough for the reaction time. With respect to the standard pulse width 80msec, the flow monitor pulse width expansion can be activated, increasing the pulse width to 300msec. Activate the smart switch, remove the cover fixed circuit board, remove the jumper X-1. This activates the extended function and allows more time before the failure instructions.Metering pump installed from the exhaust pump head, the use of self suction liquid imbibition. Keep the suction line as short as possible.
Q:Troubleshooting of diaphragm pump
The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture
Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
The power of axial flow pump decreases with the increase of flow rate, and it is a steep curve, so the centrifugal pump starts with an open valve.
Q:Is the diaphragm pump and the drain pump one?
Therefore, the need to play a liquid discharge pump, if the medium is corrosive liquid, high viscosity, volatile, flammable, highly toxic liquid, you can choose diaphragm pump. Conversely, the general liquid, there is no special requirements, you can use the general centrifugal pump to reduce costs.
Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.
Q:What are the application areas of pumps?
Water pump has different uses, different transmission liquid medium, different flow, lift range, therefore, its structure form is not the same, the material is also different, summed up, can be roughly divided into:
Q:Advantages and disadvantages of canned pumps
The graphite bearing lubrication medium, make the operation less noise and manual, reduce maintenance costs; in recent years, bearing material added with silicon carbide SIC, super hard, life is better than that of graphite bearing.The vertical structure can be installed on the pipeline like a valve, the installation is convenient and quick, and the motor and the impeller can be drawn out only when the utility model is used, and the pipeline is not needed to be removed.The utility model can be installed and run with a shock absorber or a damping pad, so that the pump is less noisy at running time.
Q:How high can the pneumatic diaphragm pump be?
Pump made of polyvinylidene fluoride (PVDF) material two, the series of pneumatic diaphragm pump belongs to the fluorine plastic pneumatic diaphragm pump is also known as the corrosion products of pneumatic diaphragm pump, diaphragm liquid contact using PTFE material, using PVDF material produced by pneumatic diaphragm pump is mainly used in corrosive the pH, mainly used for chemical liquid conveying multiple solvent, corrosion resistance effect is very good. The series of fluorine plastic pneumatic diaphragm pump in high temperature less than 93.3 degrees.POM pump material also has good resistance to solvent and abrasion resistance, low friction resistance, moisture absorption is also low, the highest temperature of such pumps within 65.5 degreesPolytetrafluoroethylene (PTFE) membrane corrosion resistance is very good, in addition to liquid metal lithium, potassium fluoride, sodium fluoride, three chlorine, three fluoride high temperature oxygen, high flow rate, almost all of the chemical liquid transport (including concentrated nitric acid and aqua regia), PTFE material the maximum temperature to 176.6 degrees. However, for the diaphragm pump product as the diaphragm moves back and forth in work, we suggest that at a temperature of 120 degrees, the prerequisite is the pump body pump must be made of metal material and plastic material. The pump is the pump of PVDF material temperature is highest in less than 93.3 degrees.
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:Is the centrifugal pump large or small?
When the liquid is lowered at a certain temperature to the vapor pressure at this temperature, the liquid bubbles. The phenomenon of producing bubbles is called cavitation. When the bubbles are flowing to the high pressure, the volume of the bubbles is reduced so that they are destroyed. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse. The local pump is in operation if the over-current part (usually the impeller blade inlet somewhere later) for some reason, the absolute pressure of pumping the liquid was reduced to liquid vapor pressure temperature, liquid vaporization began there, produce a lot of steam bubble formation, when the liquid contains a lot of bubbles by forward high pressure impeller Zone, high pressure liquid around the bubbles in the bubble decreases drastically and rupture. Condensation in the bubble burst and the liquid particle at high speed to fill a hole in this moment has a very strong effect of water hammer and the impact of high frequency against the metal surface, the impact stress of hundreds to thousands of atmospheric pressure, impact frequency can be up to tens of thousands of times per second, serious breakdown when the wall thickness will be. The process of cavitation in a pump is caused by the bursting of bubbles and bubbles in the water pump and the destruction of the over-current components. Water pump cavitation, in addition to the over-current components will have a destructive effect, but also produce noise and vibration, and lead to the performance of the pump down, seriously when the pump will be interrupted liquid, can not work properly.
