|
High pressure from a compact footprint and efficient operation within its intended duty range.
|
Not ideal for large solids, highly viscous liquids, or applications with poor suction conditions.
|
| Vertical Multistage Pump |
Approximately 1–120 m³/h |
Approximately 30–300 m |
Water boosting, boiler circulation, industrial process systems, and water-treatment skids |
Commercial high-rise projects, factories, utilities, and desalination facilities |
Consider installation height, service clearance, NPSH available, pressure rating, seal selection, and duty-point efficiency.
|
Requires a stable foundation and suitable pipe support. Variable-frequency control may require additional commissioning and protection.
|
High pressure with a relatively small floor area and flexible stage configuration.
|
Installation and maintenance may be less convenient where ceiling height or service access is limited.
|
| Peripheral or Regenerative Pump |
Approximately 0.1–8 m³/h |
Approximately 20–120 m |
Small pressure-boosting systems, fuel transfer, dosing support, and clean-fluid equipment |
Light industrial equipment, laboratory systems, small commercial installations, and agriculture |
Select only for low-flow, relatively clean liquids and verify viscosity, temperature, pressure, and continuous-duty suitability.
|
Protect against dry running and excessive inlet restriction. The motor must match local voltage, frequency, and enclosure needs.
|
Compact design, relatively high pressure for its size, and suitability for small equipment packages.
|
Flow capacity is limited and efficiency may fall significantly outside the specified operating point.
|
| Progressive Cavity Pump |
Approximately 0.05–150 m³/h |
Approximately 10–240 m |
Sludge, viscous liquids, polymers, food products, wastewater, and shear-sensitive fluids |
Food processing, wastewater treatment, chemical processing, mining, and pulp-related industries |
Match rotor and stator materials to the liquid, assess viscosity and abrasiveness, and include dry-run protection.
|
Motor sizing must account for starting torque. Hygienic or hazardous-area requirements may require specialized construction.
|
Handles viscous, abrasive, and solids-bearing fluids with steady, low-pulsation flow.
|
Dry running can quickly damage the stator; elastomer selection is critical for temperature and chemical compatibility.

|
Use compatible wetted materials, leak protection, ventilation, and electrical isolation where chemicals are hazardous.
|
Accurate metering over a wide range and strong capability for pressurized dosing.
|
Pulsating flow may require a dampener; valves and diaphragms need periodic inspection and replacement.
