APPLICATIONS

Solutions organized around the site.

Every installation starts with the liquid, the duty point and the operating environment—not simply a model number.

Municipal wastewater

Non-clogging sewage transfer

Submersible or dry-installed pumps selected around peak inflow, solids passage, wet-well geometry and automatic control.

  • WQ/QW non-clogging series
  • JYWQ automatic mixing series
  • WQK/DFQK cutting series
Chemical process

Corrosive liquid transfer

Material compatibility and containment drive the choice between diaphragm, magnetic-drive and lined centrifugal designs.

  • QBY/QBK diaphragm pumps
  • CQ/CQB magnetic pumps
  • PVDF and fluoroplastic options
Water supply

Deep-well and pressure boosting

Systems designed around dynamic water level, drawdown, delivery pressure, water quality and electrical supply.

  • SP stainless steel deep-well pumps
  • CDL/CDLF multistage pumps
  • Variable-frequency control
Mining & construction

Slurry and site dewatering

Wear-resistant wet ends, solids handling and portable installation for abrasive and sediment-laden water.

  • DFJ alloy slurry pumps
  • DFQN desilting pumps
  • High-lift submersible pumps
Energy & machinery

Lubrication and thermal circulation

Stable, low-pulsation flow for oil, heat-transfer media and machine lubrication duties.

  • ALLWEILER screw pumps
  • KSB hot-oil pumps
  • Gear pump packages
Drum handling

Safe transfer from containers

Portable barrel-pump systems selected for viscosity, chemical compatibility, motor type and required flow.

  • FTI drum and barrel pumps
  • Electric and pneumatic drives
  • Mixing and metering options
