YSM ISO PROCESS PUMP
YSM DW is a wear-resistant single-stage pump platform for abrasive, viscous, fibrous and non-fibrous slurry duties where hydraulic design and materials must be reviewed together.
PRODUCT DATA
Series maximums support early screening. Final wear life and selection depend on actual liquid and solids conditions.
| Parameter | YSM DW series range |
|---|---|
| Capacity | Up to 7,000 m³/h |
| Head | Up to 110 m |
| Pressure | 16 / 25 bar |
| Temperature | Up to 180°C |
Confirm solids size, concentration, abrasiveness, viscosity, temperature, material, seal and exact installed interfaces before production.
YSM DW can be engineered for 100% replacement compatibility with corresponding verified AHLSTAR WPP/T configurations. Exact hydraulic, wear, material and dimensional interfaces are verified for the installed pump before production.
DW supports selected abrasive, viscous, fibrous and non-fibrous slurry duties. Final material and wear review follows actual solids and operating conditions.
Flow, head, speed, liquid, concentration, viscosity and solids.
Nozzles, flanges, centerline, footprint, rotation and coupling.
Material, seal, driver, drawings and inspection scope.
Send the installed model, duty point, materials and available drawings or photos.
Project support can include casting development, precision machining, hydraulic geometry review, material control, assembly, dimensional inspection and testing when specified.
Compare the DW platform with the AC general process pump and DN non-clogging pump before requesting a quote.

Abrasive service cannot be selected from capacity and head alone. The DW review also considers solids concentration, particle characteristics, liquid properties, temperature, materials, seal arrangement and the expected wear locations inside the pump.
For a replacement project, the installed WPP/T configuration is treated as engineering evidence. Hydraulic duty and wear-critical mechanical interfaces must be checked for the specific installation.
Concentration and suspended-solids loading can materially influence wear and hydraulic behavior.
Approximate particle size, hardness and shape should be supplied where known.
Viscosity, temperature and corrosiveness affect hydraulic and material decisions.
Continuous duty, variable duty and operation away from the intended duty point can affect wear and reliability.
| Hydraulic | Flow, head, speed and operating range |
|---|---|
| Slurry | Solids concentration, particle characteristics and fibers |
| Liquid | Temperature, viscosity and chemistry/corrosiveness |
| Materials | Existing and required wetted materials |
| Installation | Nozzles, flanges, centerline, footprint and rotation |
| Mechanical | Seal, shaft/coupling, driver and bearing data |
| Evidence | Model, nameplate, GA, sectional drawing and failed-part photos |
If the existing pump has repeated erosion, short component life or unexpected hydraulic loss, include failed-component photographs and operating history so the replacement review can focus on the actual failure mechanism.
Use the DW review route when abrasion and erosion are the dominant selection risk. Use AC for broader process duties and DN when clogging, fibers or solids passage are the primary concern.
