Individually designed to meet your needs

Progressive cavity pump | biogas and industry

“From application to product”

Our progressive cavity pumps are high-quality products, which are manufactured for a wide range of applications. In order to be able to offer you the right pump, the material composition of the progressive cavity pump is individually designed according to the existing medium.

Progressive cavity pumps N series

Foot motor with bearing housing

N120 | N140

Features

The progressive cavity pumps of the N series are high-quality and very robust pumps, which are characterized by the following features:

  • Large dimensioned suction casing
  • Up to 5 suction ports possible
  • Generously dimensioned bearing bracket
  • Drive shaft with coupling
  • Use of a foot motor for easy installation
  • Mounting on a stable base frame

Progressive cavity pumps NF series

Motor flanged

N80 | N100

Features

The NF progressing cavity pump is a compact and cost-effective pump which is easy to install and does not require a separate base frame. For flow rates of up to 30 m³/h, this series is a good alternative to the N series. In this design, the gear motor is screwed directly to the progressive cavity via a flange.

Characteristics

  • Short compact design
  • 3 – 24 bar
  • 4 – 360 m³/h
  • Rotors: Hollow rotors or solid rotors in steel / stainless steel (V2A/V4A) and hardened – depending on application
  • Different joint designs, adapted to the type of application
  • Oil chamber seal housing with mechanical seals
  • Stators in various elastomers (NBR, EPDM, PTFE, PU, CSM) – alternatively: retightenable for longer service life
  • Disassembly/assembly possible without special tools

Pumpable media

  • Maize
  • Grass silage
  • Food scraps
  • Fruit waste
  • Liquid manure
  • Waste water
  • Emulsions
  • Sludge
  • Fruit mash
  • Paints
  • Varnishes

Stators

For all applications where elastomer stators can be used, an adjustable stator is available, which significantly increases economic efficiency.

The stator can be continuously adjusted over a wide range when the pump performance decreases; this extends the service life of the stator by a factor of 4 to 6. The special design of the adjustable stator ensures a radially uniform contact pressure and full tightness.
