NEMO® SY in Bearing Block Design

NEMO® SY in Bearing Block Design With Free Shaft Extension

Used worldwide for demanding applications in every branch of industry

The NEMO® SY Progressing Cavity Pump is used for demanding applications in every industrial market worldwide. Bearing housing design with free input shaft pump can be run with any type of drive, such as servo motors, diesel motors or hydraulic drives. This pump can also handle high-pressure applications. Four rotor/stator geometries are available, to customize the pump for your application. The NEMO® SY is suitable for all industrial markets where low- to mid-viscosity and/or shear-sensitive, abrasive or adhesive substances must be safely and gently handled.

Features of the NEMO® SY Progressing Cavity Pump

  • continuous low-pulsation conveyance unaffected by fluctuations in pressure and viscosity
  • capacity in proportion to rotation speed with high metering precision over a wide speed range
  • high pressure capability without valves
  • mechanical seal is located at the front of the product flow, making flushing unnecessary in many applications.
  • easy stator replacement

The NEMO® SY Progressing Cavity Pump offers you:

  • conveying pressure up to 1000 psi
  • gentle product conveyance
  • pump connections in accordance with national and international standards, as well as in specially designed models
  • easy serviceability
