I-1B series Centrifugal Slurry Pump for printing and dyeing



I-1B thick slurry pump overview


The I-1B series of thick slurry pumps are single screw type rotary pumps which utilize the rotation of the screw of the eccentric single helix in the double screw bushing so that the thick slurry is moved from the suction port to the discharge port along the spiral groove to achieve pump delivery Features



I-1B thick slurry pump structure material type


I-1B type: shell cast iron, transmission parts for the general steel, suitable for general neutral thick slurry transport.

I-1B type: transmission parts (spindle, screw and shaft) is made of stainless steel, suitable for general slightly acidic, alkaline slurry delivery.

Type I-1B: drive and angle of the slurry pump shell are made of stainless steel, suitable for food, pharmaceutical and corrosive slurry delivery.

Rubber bushings are generally wear-resistant rubber, food with rubber and oil-resistant rubber for the user to choose.

Transmission mode with a direct drive motor and pump shaft, the motor by the reducer and pump direct drive and motor by the triangular pulley and pump shaft drive for users to buy.

Equipped with the motor are generally closed, explosion-proof and electromagnetic speed control motor.



I-1B thick slurry pump use range

  1. Can transport high concentration and high viscosity (<10000PaS) and suspended particles containing particles.
  2. Transport flow stability, no overcurrent, pulsation and stirring, shear slurry phenomenon.
  3. The discharge pressure has nothing to do with the speed, low flow can also maintain a high discharge pressure.
  4. Flow rate is proportional to the speed, through the transmission mechanism or high-speed motor can achieve flow adjustment.
  5. Self-priming ability, the liquid flow from the direction of rotation of the pump to change, apply to the pipeline to be anti-positive flushing occasions.
  6. Smooth operation, vibration, noise.
  7. Simple structure, disassembly, easy maintenance.

Screw pump (thick pump) is a new type of liquid transport machinery, with a simple structure, safe and reliable work, easy maintenance and use, the liquid continuous uniform pressure stability and so on. I plant the production of thick slurry pump where the metal parts of contact materials are made of high-quality acid and stainless steel production, liner with non-toxic and tasteless rubber, the working temperature of up to 120 ℃, can be used for conveying food slurry and viscosity 10000 pound card A solution slurry containing a solid particle or a mass, and a corrosive medium of the suspension. Widely used in food, metallurgy, chemical, printing and dyeing, paper, ceramics and other industrial sectors.

Fault and exclusion


Malfunction reason Method of exclusion
1. Starting difficulties

1. The material is not filled with pump cavity. Friction resistance is large:

2. The packing gland is too tight and the friction torque between the shaft and the packing is too large.

1. With the pipe clamp to move the shaft pump shaft 3 ~ 6 turn:

2. Adjust the packing gland.


2. No liquid after starting

1. A large number of air inhalation:

2. The motor turns wrong:

3. Material viscosity is too large.

1. Check if the suction level is too low

2. Any two phases of the motor connected to the line:

3. dilute the liquid.


3. Pumps have greater vibration or noise

1. Motor and pump shaft are not concentric:

2. Pump inhalation of air or liquid mixed with a lot of air

1. Re-adjust the coaxiality:

2. Check the liquid level and try to remove the air from the inhalation solution..

4. During the operation, the flow rate drops significantly

1. Bushing wear.

2. Speed reduction:

3. Universal joint shaft or axis damage Transmission failure:

4. Inhalation of piping into the liquid depth is not enough. There is air into the pump

1. Replace the bushing. If necessary, change the screw:

2. Check the power and motor:

3. Shut down the maintenance. Replace the shaft I axis or around the axis:

4. Small inhalation height. It is used to remove the air in the feed.


5. Motor overload

1. Head over the pump too much:

2. Material viscosity is too large:

3. The voltage is too low.

1. Minimize piping head loss or replace high lift pump.

2. Diluent:

3. Check the cause. Increase the voltage to the specified value.


6. Shaft seal a lot of leakage

1. Gland too loose:

2. Filling:

3. Import and export position anti.

1. Adjust the gland:

2. Replace packing:

3. Take the middle flange as the suction port.



Installation Notes


According to the pump's total drawings and instructions provided by the installation of the size of the casting base and determine the location of the anchor bolts, under normal circumstances should not change the direction of imports. The base surface should be leveled using the level, until the foundation of the cement after the solidification of the pump installed on the basis. Coaxiality of motor shaft and pump shaft. The two axes are offset by no more than ± 0.2 mm. If the axis does not coincide, it will produce vibration to make the bearing heat, or even damage the pump.

Pump suction and discharge pipes should have their own and the bracket, generally do not allow the pump to withstand the weight of the pipeline, the pump can be installed in the tank can not install the end of the valve, but should be installed in the suction pipe control valve and filter device to Anti-debris inhalation pump. When the pump is installed above the liquid level position, it should be installed at the end of the suction pipe end valve, and the bottom valve throat area should be larger than 50% of the cross section of the suction pipe.

Before the installation of the pump must be completely removed from the pipeline debris, such as: welding slag, metal shavings, etc., so as to avoid the pump was inhalation caused by accident.



  1. Expect the necessary wrenches and tools.
  2. Check the base. Bearing and oil chamber without lubricants,
  3. Check that the hollow shaft and shaft seal are appropriate. The packing gland can not be pressed too tightly.
  4. Turn the jaws by hand or pipe clamp. Note that there is no foreign matter in the pump body noise and stuck phenomenon.If you should be cleared before driving
  5. Fill the pump chamber with the material. Do not run on the friction
  6. out of the gate valve
  7. Turn on the motor.


  1. Close the suction pipe valve.
  2. Close the drain valve.
  3. Stop the motor. When the pump is in the long-term stop operation, the pump chamber should be drained and rinsed with water or steam.


  1. Always check pump and motor bearing temperature rise. The maximum temperature should not exceed 75 ℃.
  2. Timely fill the lubricating oil to ensure good bearing lubrication.
  3. During operation, if abnormal noise or excessive vibration should be found immediately stop inspection.
  4. When the flow is significantly reduced, indicating that the rubber village has been worn. Should be replaced after the new village sets of operation.
