YZW Series Self-Suction Centrifugal Water Pump
YZW Series Self-Suction Centrifugal Water Pump
Water Pump for Stone Cutting and Processing Equipment
Water is an important part of stone processing. Cutting blades need continuous cooling during operation, and many stone machines use water to control dust and carry away stone slurry.
The YZW series is a self-suction centrifugal pump used for these water supply and circulation requirements. It is available in single-inlet and double-inlet configurations, with 15kW and 22kW motor options.
This type of pump is mainly used with stone processing equipment and can be installed with a water tank and 4-inch water pipes according to the factory's water system.
YZW Water Pump Models
The YZW series includes the YZW-425 and YZW-620 configurations. The pump shown below can be supplied in different arrangements depending on the required water flow and installation method.

Construction and Working Features
The YZW pump uses a self-suction centrifugal structure. A water storage tank can be installed with the pump, allowing the pump and the factory water system to work together.
The pump uses a double-seal structure around the sealing area. An oil cup is also provided for lubrication and cooling of the relevant components during operation.
For installations requiring more water, the double-inlet version uses two 4-inch water connections. The choice between the single-inlet and double-inlet arrangement depends on the water demand of the connected machines.
Available YZW-425 Specifications
The following figures are the available specifications for the YZW-425 configurations.
| Configuration | Water Connection | Flow Rate | Head | Motor Power |
|---|---|---|---|---|
| YZW-425 Single Inlet | Ø100 mm | 120 m³/h | 25 m | 15 kW |
| YZW-425 Single Inlet | Ø100 mm | 150 m³/h | 25 m | 22 kW |
| YZW-425 Double Inlet | Ø100 × 2 | 150 m³/h | 20 m | 15 kW |
| YZW-425 Double Inlet | Ø100 × 2 | 180 m³/h | 20 m | 22 kW |
Note: The figures above are reference specifications. Actual water flow can be affected by pipe length, pipe arrangement, water source and installation conditions.
Use with Stone Processing Machinery
In a stone factory, the water pump is normally connected to the plant water system rather than to one machine alone. Water can be supplied to several processing machines through the factory's pipe network.
Typical applications include water supply for:
- Bridge cutting machines
- Block cutting machines
- Stone slab cutting machines
- Grinding and polishing machines
- Other water-cooled stone processing equipment
The required pump capacity depends on how many machines are running at the same time and how much water each machine needs.
Water Supply and Circulation
A typical installation consists of a water source or collection tank, the YZW pump, water pipes and the connected stone machines. In plants where process water is collected after cutting, the same system can also be arranged for water circulation.
The actual pipe arrangement is determined by the factory layout. The distance between the pump and machines, the number of machines and the height difference in the pipeline all affect the pump selection.
For this reason, the pump should not be selected by motor power alone. Flow rate, head and pipeline conditions should be considered together.
Single-Inlet or Double-Inlet Water Pump?
The main difference between the two configurations is the water inlet arrangement and the resulting flow capacity.
The single-inlet version has one Ø100 mm water connection. It can be used where the water requirement of the processing system is within the capacity of the single-inlet model.
The double-inlet version has two Ø100 mm water connections. It is used where a larger water flow is required. Based on the listed YZW-425 specifications, the double-inlet configuration reaches up to 180 m³/h with the 22kW motor.
The suitable configuration should be determined from the actual water consumption and pipe layout of the stone factory.
Installation Examples
The YZW pump can be installed with different pipe arrangements. The following configurations are shown in the installation examples:
- YZW-22 with 4-inch double-inlet pipes
- YZW-15 with 4-inch single-inlet pipes
- YZW-15 with 4-inch double-inlet pipes
- YZW-15 with 4-inch single-inlet pipes
Before installation, check the water source, suction pipe, discharge pipe, pipe diameter and installation position. The pipeline should also be arranged to avoid unnecessary bends and restrictions that may affect water flow.
Points to Check During Operation
For a water pump working continuously in a stone factory, regular inspection of the water system is useful. Stone slurry and other particles should not be allowed to accumulate in the pipes or affect the water inlet.
- Check the water pipe connections for leakage.
- Keep the water inlet and suction pipe free from blockage.
- Check the pump lubrication condition during regular maintenance.
- Pay attention to unusual noise or vibration during operation.
- Check the motor and electrical supply before starting the pump.
Water Pump for Stone Factories in Africa
Stone processing is carried out in many African markets, including marble and granite processing plants. In these factories, water supply is part of the daily operation of cutting and processing equipment.
When selecting a water pump for a stone factory in Africa, the local electrical supply should be confirmed together with the required water flow and pump head. The distance from the water source to the processing area is also important when determining the pipeline arrangement.
The YZW series can be considered for stone processing plants that require a self-suction centrifugal pump with 4-inch water connections and different flow configurations.
Information Required for Pump Selection
If the pump is being selected for a new stone factory or an existing production line, the following information is useful:
- Number and type of stone machines
- Estimated total water consumption
- Distance between the water source and machines
- Required water lifting height
- Existing pipe diameter
- Available electrical power supply
With these details, the pump configuration can be checked against the actual installation instead of selecting a model based only on motor power.
Questions About the YZW Water Pump
What is the YZW pump mainly used for?
The YZW series is mainly used for water extraction and circulation in stone processing factories and other applications that require a centrifugal water pump.
What motor powers are available?
