Influencing factors of Submersible Agitator Sand Pump Price

Submersible agitator sand pump is a kind of slurry pump which can be installed on the land or sand dredger for sand and slurry pumping. Submersible agitator sand pump puts the electrical motor and mechanical pump on the same axis. It has the characteristics of high efficiency, abrasion resistant, automatic coupling and long life span, etc. Submersible agitator sand pump is suitable for conveying liquid with slurry, solid particles of gravel, cinders and tailing, etc.

Recently, there are two questions often asked by OCEAN Pump customers.

1. Under the same power, why the submersible agitator sand pump made  by OCEAN Pump has higher weight and price ?
2. With same specification, why customers don’t choose the submersible sand pump which looks more cost effective?

OCEAN Pump technical department selected two kinds of products from different places, also known as submersible agitator sand pump, by comparing them with OCEAN Pump sand pump machine, we can explain the customers’ questions in different aspects.

Here are the Influencing Factors of Submersible Agitator Sand Pump Price

1. There are Differences in Structure 
The design of the submersible agitator sand pump is based on the horizontal slurry pump and the large particle sand pump, with the same drawings of the over-flow components such as the pump impeller and pump case. Electric motor is low-speed and high-torque, considering of extreme conditions, electric motor is designed with higher protection and insulation grade. The submersible electric motor designed by OCEAN Pump has overload protection probe, water inlet probe and oil water probe to avoid the loss caused by electric motor failure.
The base of the submersible agitator sand pump which from the other supplier is submersible sewage pump, which is a common sewage pump. By using the electric motor of the submersible sewage pump and then replacing the overflow parts with ductile iron or high-chromium cast iron, the advantage of this pump is lighter and suitable for the extraction of sewage or a small amount of mud.
2.Different Volume and Weight  
Taking 22 kw submersible agitator sand pump for example, sand pump weight of OCEAN Pump is 660 kg and the dimension (L*W*H) is 1375*630*870 mm. The other two sand pumps are weighed and measured separately, one pump weighs 260 Kg with dimension (L*W*H) 1055*420*650 mm, the other weighs 280 kg and the dimension (L*W*H ) is 1100*480*550 mm. Only comparing the weight, Our Pump is two times than the others suppliers’.

What is the reason for the difference in weight and volume?
The main reason is that the number of poles on the motor is limited. The other manufacturers’ products are 4-pole motors with speed of 1450 r/min. The submersible agitator sand pump of the OCEAN Pump  is 6-pole motor with speed of 980 r/min. It is well known that the lower the number of poles of the motor, the lower the rotational speed, the larger weight and the greater the torque. For the sand pump, it is sure that the torque of the pump is as large as possible. The higher the torque, the more powerful the submersible agitator sand pump will be. Moreover, for the overflow components, the lower the rotation speed, the smaller the wear. However, the pump case and impeller are larger for the submersible sand pump with lower rotation speed, and it is heavier than the pump with high speed. The electric hoist needs to be bigger used for lifting .
3. Different Application Range
The submersible agitator sand pump produced by OCEAN Pump was originally called submersible slurry pump. It was mainly used to extract liquids containing solid particles such as slurry, cinder, tailing, etc. After modified the pump type by OCEAN Pump, the channel of the submersible slurry pump was widened. The jet-type submersible agitator sand pump and submersible agitator sand pump with side-agitators were designed, and the application range extends to the construction site such as sand pumping, dredging and environmental protection equipment.

The submersible agitator pump produced by the others suppliers can be used to extract mud, sewage or working conditions with low specific gravity of solid particles, or short-term sand pumping, but it is not suitable for the extraction of coarse sand or large granular solids. If it is used for sand pumping or dredging, it is prone to faults such as motor overload burnout or spindle breakage, which seriously affects the construction progress.
 4. The Difference in Life Span
Due to the different motor speed, the wear of the high-speed submersible agitator pump is much higher than that of the low-speed pump type under the same flow and head condition, which is equivalent to the solid-liquid mixture under the same unit volume, the impeller of submersible slurry pump produced by OCEAN Pump is only ground in one turn, and the high-speed product is ground twice. Even with the same type of pump, the wear will vary greatly. This is why the pump speed on the large cutter suction sand pump is only 200-300 rpm. The volume of cutter pump is very large, and some will be taller than a house. It is because of the high torque impeller. Under the premise of ensuring the flow and head, the speed should be reduced as much as possible to ensure the service life of the pump.
In summary, when selecting submersible agitator pump, the customer must not only check the flow and head of the pump, but also the structure of the pump, the weight and volume, and the applicable range, so that a suitable submersible slurry pump type can be selected.
