Downstream – NEMO® Transfer Pumps

No matter what the distance – NEMO® Transfer Pumps can handle it

General

Great distances must often be covered in order to reach ports or refineries. Pump systems that can maintain a high conveying pressure at the lowest possible pulsation are required for such applications. NETZSCH Progressing Cavity Pumps fulfill these requirements. NEMO® Pumps are produced in accordance with API 676 and shaft seals in accordance with API 682.

Features of NEMO® Transfer Pumps:

  • unsusceptible to sandy content in the pumped product
  • provide low-pulsation handling
  • provide high suction capability

NEMO® Transfer Pumps offer you:

  • low life cycle costs
  • high pressure stability
  • precision metering

Advantages of the NEMO® Transfer Pump

  • handles oil with high water content
  • operates dependably with high-viscosity oils
  • is designed for substances with high solid content
