Series PD-430 Progressing Cavity Pump
VQ-PD430
Positive displacement pump, flow 0.5 to 35 m³/h, pressure to 12 bar.
- FLOW
- 0.5 to 35 m³/h
- PRESSURE
- to 12 bar
- VISCOSITY
- 1 to 200,000 mPas
- TEMPERATURE
- -10 to +120 °C
Why it is specified
When the liquid is thick, shear-sensitive or full of solids, a centrifugal pump stops being a pump. These displace a fixed volume per revolution, so flow follows speed and viscosity barely matters.
Typical applications
- Dewatering and filter press feed
- Food and beverage transfer
- Polymer and adhesive feed
- Sludge and slurry transfer
- Viscous product dosing
Options and executions
- Double mechanical seal with flush
- Heating jacket on the pump head
- Pressure relief valve on the head
- Trolley or skid mounting
- Variable speed drive
