DescriptionModel Meaning
AWQS Series shredding submersible sewage pump is developed on the basis of fully studying domestic and foreign technologies and market demand of submersible sewage pump. It can shred sewage and fibers and discharge them automatically, which is provided with functions of super anti-jamming, anti-twisting and self cleaning, especially applicable for the working condition of long fibers. Based on the professional and reliable submersible motor and integrating the advanced shredding and blowdown technologies, AWQS series shredding submersible sewage pump has many advantages:
Saving investment and running costs:
Saving investment: Our shredding submersible sewage pump is featured by its original design, compact structure and small appearance. The motor’s allowable starting frequency within the unit hour has been increased substantially, which can reduce the sump’s designed capacity; therefore, more construction investment can be saved.
Efficient and energy-saving: Its hydraulic design for shredding and blow down, selected materials and high-quality casting and processing can meet the needs for shredding, blow down and efficiency at the same time.
Easy for maintenance:

The advanced self-coupling device makes underwater operation unnecessary when the pump lifts and drops, thus easy for maintenance, time-saving and labor-saving; it adopts the stainless steel bolts which can stay stainless for long easy for disassembly and assembly; the wearing plate’s axial dimensions can be adjustable to suit to the abrasion and reduce the frequency of maintenance; its dedicated electrical control cabinet can achieve such functions as automatic alarm, stop an keeping fault signals, which can improve the maintenance efficiency a lot.
Fewer and smaller spare parts: Fewer and smaller spare parts are needed due to those parts with the modular design like submersible motor and oil chamber plus the protection of self-cleaning wearing plate over the pump body, thus the pump operation is more economical.
Stable and reliable operation of pump
Brand-name bearing and heavy-duty design: The special hydraulic design and the precise balance working procedure can reduce the axial and radial forces substantially; the compact seal configuration makes the shaft extension shorter; plus, the oversize bearing ensures the pump’s long-term and stable operation.
Reliable operation of shaft: The gudgeon and bellows mechanical seals ensure that the pump shaft doesn’t contact the medium directly and avoid the abrasion and corrosion, so the system can operate for long.
Anti-jamming and anti-twisting: The impeller and the wearing plate with superhard materials form a pair of cutters to shred sewage and fibers and discharge them automatically, thus ensuring that the pump’s operation is anti-jamming and anti-twisting.
Safe and reliable submersible motor Advanced core technology: The casing’s protection class is IP68; the stator winding is resistant to a temperature as high as 145℃and the insulation class is F. Multiple detection with multiple protections: Its leak probe, floating switch and overheating protection element in its motor are all available for real-time detection as well as functions like alarm, stop and keeping fault signals, ensuring that no water enters into the motor.
Double seal with double protection: The mechanical seal adopts the rubber bellows structure to prevent sand and scale; the unique dynamic anti-sand design can extend the mechanical seal’s life longer; the mechanical seal adopts a world-famous brand with quality assurance; the serial configuration of double mechanical seals (relative to double end faces )
Can achieve the double protection really, ensuring the motor’s safety.

Q:A pump, the flow rate of 30T/H per hour, lift 30 meters, should be allocated more power motor?
Depends on how big your water pump is. How long is the pipe length?
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:The role of impeller in water pump
The impeller is driven by electric motor rotation, the middle impeller creates a vacuum to vacuum at the inflow of water will be (on the surface water is continuously sucked into the impeller), then the water through the high-speed rotation of the impeller of the water discharge, play a promoting role in water.
Q:How can I pump the motor insulation?
A submersible pump to shake the insulation, water pump distance more than 20 meters away from the cable distribution box is fixed, at this time to shake the insulation in the distance distribution box can only shake, disconnect the power cable is connected with the shake table, the ground end is connected with the electric box so that the pump shell shake shake, also must be reliable grounding to shake to now, the pump shell grounding not only in the water, it must be a wire connected with a shell or a wire will be immersed in water, this is right insulating shake,
Q:What is the influence of the speed of the pump motor on the pump?
Influence the parameters of pump flow and lift.
Q:What is the function of the pump?
Drainage or irrigation
Q:What are the quota items for the complete pump installation?
Pump installation / anchor bolt installation anchor bolt hole, fill oar vibration cushion installation
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:90kw pump star delta start, in the end to use the circuit breaker, AC contactor (Star contactor, angle contactor), what kind of thermal relay?
The star delta circuit you give belongs to the international standard starting mode, different from the old gb. The first said (the old national standard, is actually the domestic elders step-down manner, they are the main contactor) after shunt implementation of star triangle, so there will be a larger contactor, down economic calculation.And the new international standard (you give the circuit diagram) can be seen that the air switch to select the motor current to meet the given amount of surplus, 90kw motor rated current 175A, so choose 225A air switch can be. 1KM 2KM is the main operation of contactors, contactor, they each pay half the current line in triangle, so choose 110A (like never seen 100A) current, 3KM star, because of short-time current will not cause damage to the contact, a little lower 80A is not affected. Heat meter: if you don't use a transformer, you can choose JR36---160A.Some friends may feel small, in fact as long as you pay attention, you will find a lot of electrical equipment factory are doing this standard. In this way, both cost savings and service requirements are met.
Q:Horizontal pumps, vertical pumps, which kind of expensive?
Relatively speaking, the horizontal is expensive, because there is a horizontal chassis, if there is a large pump case, the best selection of horizontal, otherwise the weight of the motor to the pump body smashed!
