Slurry Vacuum Pump: Things You May Want to Know

Slurry pumps belong to the category of centrifugal pumps. Slurry pump refers to a kind of machine that increases the energy of solid and liquid mixed medium by means of centrifugal force.
Centrifugal pumps work by rotating the impeller to cause centrifugal motion of water. Before the pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and the water to rotate at a high speed. into the pressurized water line of the pump.
The basic structure of a centrifugal pump is composed of eight parts, namely: impeller, pump body, pump cover, water retaining ring, pump shaft, bearing, sealing ring, stuffing box, and axial force balance device.
1. The impeller is the core part of the centrifugal pump. It has a high speed and a large output force.
2. The pump body is also called the pump casing, which is the main body of the pump. It plays the role of supporting and fixing, and is connected with the bracket on which the bearing is installed.
3. The function of the pump shaft is to connect the motor with the coupling and transmit the torque of the motor to the impeller, so it is the main component for transmitting mechanical energy.
4. The sealing ring is also called the leakage reducing ring.
5. The stuffing box is mainly made of stuffing, so that the water flow in the pump does not flow to the outside and the outside air does not enter the pump. Always maintain a vacuum inside the pump! When the friction between the pump shaft and the packing generates heat, the water seal pipe is used to inject water into the water seal ring to cool the packing!
6. Axial force balance device. During the operation of the centrifugal pump, since the liquid enters the impeller under low pressure and flows out under high pressure, the pressure on both sides of the impeller is unequal, resulting in an axial thrust directed towards the inlet. It will cause axial movement of the rotor, resulting in wear and vibration, so an axial thrust bearing should be installed to balance the axial force.

Follow these three key instructions to determine the flow rate:


If the production process specifies minimum, normal, and maximum flow rates, use the maximum flow rate as the benchmark.
If only the normal flow rate is given, allocate a margin:


For high-flow, low-head pumps (ns > 100), allow a 5% margin.
For low-flow, high-head pumps (ns < 50), allow 10%.
For pumps with 50 ≤ ns ≤ 100, use a 5% margin. Increase to 10% for poor-quality pumps or harsh conditions.


Convert weight-based flow rates to volumetric flow rates if necessary.

Accurate flow rate determination improves operational efficiency.

Proper lubrication reduces friction, prevents corrosion, and extends bearing life. Methods include:
1. Drip Lubrication: For low/mid-speed bearings (<5 m/s). Adjust drip rate (3–8 sec/drop). Over-lubrication causes overheating.
2. Manual Lubrication: For light loads or intermittent use. Use filtered covers to prevent contamination.
3. Oil Ring Lubrication: For horizontal shafts (>50 mm diameter). Use one ring for width/diameter ratio <2.
4. Oil Bath Lubrication: Immerse bearings partially; oil level below the lowest roller center.
5. Circulating Oil: For high-speed bearings. Filtered oil cools and lubricates via a pump system.
6. Spray Lubrication: For high-speed/high-temperature bearings. Compressed air delivers oil mist while cooling.
Key Notes:
Maintain seal water pressure and adjust packing to prevent leaks.
Keep bearings clean; operating temp ≤ 65°C (max 75°C).
Ensure motor-pump alignment and inspect coupling elastomers regularly.
Monitor wear-prone parts and replace them promptly.
Choose lubrication methods based on speed, load, and environment to optimize pump performance and longevity.
