Product Description:


ASP1040 series flue gas desulphurization pumps are single stage single suction centrifugal pumps,which are applied for wet flue gas desulphurization equipment(FGD)in power plant,transmitting corrosive slurry for absorption tower circulation pump.They are characterized by large capacity,high efficiency,wear-resistance,compact structure,reliable running and low vibration,etc.The technical indexes reach the same kind product level home and aboard .The most important advantages are their excellent performances and easy maintenance.

Application Area

The products have been applied in limestone plaster wet desulphurization equipments.

Performance Range

Discharge diameter:DN=50~900 mm   

Capacity:Q=45~18500 m3/h

Head:H=16~105 m

Structural Characteristics

Flue gas desulphurization pump is single stage single suction centrifugal pump,which applies support structure.The material option has fully metal or natural rubber plus metal to meet different users’ requirements.

The pump has a better efficiency by using advanced hydraulic model and computational fluid dynamic software(CFD) to improve it.

End face seal is applied for impeller.Impellers can be optimally positioned by adjusting bearing assembly,which can enhance pump reliability and ensure that pump is highly efficient in operation.

Wet parts adopt different materials combination based on different work conditions to make pump manufacture and usage the most economic and reliable.

Pump can be disassembled form front and back,unnecessary to disassemble inlet and outlet pipelines,which is convenient for maintenance.

Thin oil lubrication is used on the bearings,which can improve the lubricating and cooling condition and also extend service life of bearings.

Seal can be selected according to different users and work conditions.There is assembly mechanical seal,packing seal,and auxiliary impeller with packing seal.In order to run reliably,wear-resistant corrosion-resistant metal rings are applied for seal rings in the case of assembly mechanical seal ,which can enhance seal ring capacities of anti-impact and heat dissipation and also can be washed down from inside or outside.

Platinum resistance is fitted on bearing for testing bearing temperature to avoid damage of bearing.

Q:How to maintain and repair the booster pump of pipeline pump?
Two 、 troubleshootingfaultReasonRemoval method1. water pump does not produce waterThe water injected into the water pump is not enough, the rotation direction is not right, and the impeller passage is blocked.Pump water into the pump, pass through the impeller runner, adjust the direction of rotation.2. pump flow is insufficientThe pump speed is too low, part of the blockage, the total lift pump is higher than the rated value, the damage to the impeller.Clean the water pump and pipe, replace the impeller, increase the pump shaft revolutions, adjust the outlet valve.3. lack of outlet pressureThere is air in the liquid, the speed is too low, the impeller is damaged and the outlet valve is open.Exclude liquid air, increase the pump speed, replace the impeller, adjust the small outlet valve.
Q:How many square cables does the submersible pump for 7.5KW need?
I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).
Q:What is the "variable" of a variable pump?
These two don't mean the same thing? That is, the pump outlet can be changed
Q:What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
Mechanical efficiency: the ratio of theoretical torque to actual torque of the pump.
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
When the vacuum pressure is called vaporization pressure, cavitation is more than the surplus energy of vaporization pressure at the unit weight of the liquid in the pump suction port of the unit, with mark. The absorption process is to NPSH delta H: pump suction fluid allows the vacuum pump installation height is the unit of rice.
Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
As the name suggests, centrifuges are machines that achieve centrifugal effects by centrifugal action. And you say the centrifugal pump is only specific, and the same as the pump
Q:How many pumps does the 80cm tank use?
Mainly look at the flow of the pump, all pumps have flow signs, such as 15L/HThe above is I at random, meaning that 15 litres per hour. You should calculate the volume of your cylinder, that is, the length of the tank, the width and the height of the water surface, the unit is cm. The result is 1000, which is the volume of your fish tank
Q:What is the function of the heating pump system for the water pump design?
As the feed water temperature is higher, before starting, if not enough to warm the pump, the pump body temperature is uneven, there is a hot, cool phenomenon. The upper part is inflated and the lower part is inflated"
Q:Fire hydrant pump button, under what circumstances do not need to install?
The installation of hydrant pump buttons depends on the type of water supply:(1) municipal water supply; (in this case, do not have to install)(2) there is a fire pump; (must be installed)
Q:The main factors affecting the performance of centrifugal pumps
Revolutions required to have. It has the following meanings: 1, similar to the geometry of centrifugal pump, everywhere efficiency at the top of the similar condition; centrifugal pump 2, than the number of different, its geometry must be different than the number; the same pump, its shape is similar, but does not rule out the shape similar situation. The following factors are related to specific speed. The specific speed of centrifugal pump has nothing to do with the nature of the conveying fluid, but has a close relationship with the shape of the impeller and the performance curve of the pump. The pump with high specific speed corresponds to the highest efficiency when the flow rate is large and the head is small
