Submersible Slurry Pump

MSP Submersible Slurry Pumps are designed to dewater the most abrasive sumps and ponds found in mining, Designed with high standard motors and cast high chrome wet-ends, these submersible slurry pumps have proven very reliable and an excellent alternative to the high maintenance vertical cantilever style pumps.

It mainly conveys media containing solid particles ( such as ore powder , ash , iron oxide scale , coal slime , mud sand and gravel , etc .) below 70°℃, suitable for mining , metallurgy , electric power , coal , river dredging , sand dredging and other industries .  Capacity range: 25-5500 m3/h, Head range :9-135m, Power range: 4-560kw.

Technical Features:

1. The pump shell and impeller are made of high chrome alloy material, the latest design of impeller, volute liner efficiency of more than 80%.

2. This pump adopts double mechanical seal design, one set of mechanical seal is installed in the oil chamber, another set contact with the transmission of medium liquid. Add cooling oil to the oil chamber to lubricate, cool and clean the mechanical seal, the service life is more than 30,000 hours.

3. The motor shell can be made of Q235 steel, which is better than ordinary cast iron to  improve the protection level. The fastening screw is made of 316 material to ensure the operating life of the motor, which is twice longer than ordinary material.

4. The fixed rotor of the motor is with higher electromagnetic efficiency, electromagnetic copper wire Q2T/180 is high temperature resistant copper wire.

5.The motor structure is redesigned and optimized, supported by new bearing structure, and the motor shaft is treated with 4Cr13 conditioning. The motor ' s operating life is greatly extended, which is more than 2 times of the traditional motor.

6.Electric control can be customized 380V-600V voltage range, 50-60Hz frequency. Monitoring and protection using PLC screen display can realize the pump group operation bearing temperature, sealing leakage, motor overheating and other problems.

7.The connection of cable and motor adopts secondary protection design to protect the motor.

8.The equipment can be fixed or moveable installation.

Advantanges:

1. The pump runs smoothly and freely , without jamming and stagnation.

2. After the assembly of the pump, the sealing device on one side of the pump was subjected to air pressure test, the test pressure was 3bar, and the test lasted for 5min without leakage.

3. The design service life of the mechanical seal is not less than 15000 hours, the service life of the bearing is not less than 50000 hours; The service life of the equipment is no less than 2 years.

4. All sealing parts of the pump are subjected to pressure test without leakage, the test pressure is 3bar, lasting 5min.

5.The pump nameplate is marked with obvious rotation direction.

6.Dynamic balance test of pump impeller and rotor, balance accuracy grade is G6.3.

7.When the pump is used at full head, the power curve is stable.

8.The pump runs continuously in the pumping medium and is allowed to start 15 times per hour without affecting the service life.
