NEMO C.Pro Dosing Pump

NEMO® C.Pro Dosing Pump:

Your Universally Applicable, Almost Maintenance-Free Pump Consisting of Six Main Parts

The NEMO® C.Pro dosing pump is a fully synthetic pump for the precise dosing of a great variety of chemicals in environmental technology and the chemical industry.

Its synthetic construction makes it perfectly suited for the gentle and low-pulsation conveyance and dosing of aggressive or non-aggressive chemicals. With only six main parts, the NEMO® C.Pro is particularly easy to service and economical. Features of the NEMO® C.Pro:

  • Universally applicable for many media - even acids and bases
  • Continuous low-pulsation conveyance unaffected by fluctuations in pressure and viscosity
  • Conveyance volume in proportion to rotation speed with high dosing precision over the entire rotational-speed range

The NEMO® C.Pro offers you:

  • Constant and nearly pulsation-free dosing
  • Dosing in proportion to rotation speed
  • Reversible direction of rotation and dosing
  • Large dosing range
  • Gentle product conveyance
  • Easy serviceability

Everything from a single supplier: For the most varied of applications in your processes, it is now possible to procure the NEMO® progressing cavity pumps together with the well-known NETZSCH TORNADO® industrial rotary lobe pumps. Take advantage of our decades of experience and know-how in the manufacturing of positive-displacement pumps.

NEMO® C.Pro Universal Dosing Pump

1. Rotating Unit
A jointless single-part rotating unit made of maintenance-free plastic. For conveying abrasive or non-lubricating media, the C.Pro can be equipped with a rotor chromed in high-grade steel.

2. Stator
The C.Pro Pump comes fitted as standard with an iFD-Stator®. The stator consists of a reusable stator housing with a polygonal profile and an elastomer stator core. Some advantages of this new technology include low breakaway torque, higher efficiency, increased operating life, simple and quick replacement, and hassle-free disposal.

3. Mechanical Seal and Housing
The crevice-free mechanical seal is positioned in the product flow, ensuring permanent flushing by the medium and preventing the sedimentation of solid materials. Comes standard with a fully encapsulated single-acting bi-directional rubber boot seal and anti-friction surfaces made of solid SiC.

4. Suction Housing
The housing is made of abrasion-proof, highly resistant polyurethane. The universal flange with nominal width DN20 PN16 to DIN and ¾" to ANSI B16,5 150 LBS makes installation and removal from the plant easy.

5. Stator and Discharge Housing
The connection is made of abrasion-proof, highly resistant polyurethane. Again the universal flange with nominal width DN20 PN16 to DIN and ¾" to ANSI B16,5 150 LBS allows easy installation and removal from the plant.

6. Drive
Comes standard with a speed-controlled 6-pole three-phase motor and frequency converter for control panel mounting. Optionally also available with 6-pole three-phase motor complete with cooling fan and integrated frequency converter for manual speed control via integrated potentiometer or control by a 4-20 mA/2-10V signal.

Performance Spectrum:

  • Flow rates from 0.5 to 1500 L/h
  • Pressures up to 15 bar
  • Temperature range from 0 °C to 40 °C
  • High dosing precision with deviation +/-1% 


The C.Pro offers you a comprehensive solution for dosing all types of chemicals in industry and environmental technology. There are countless applications in many industries where chemicals with very different properties require precise dosing. The C.Pro performs this function not only with very high precision, but also gently and under low pulsation. The NEMO® C.Pro progressing cavity pump has a wide spectrum of applications and is used primarily for substances with the following properties:

  • Products with or without solid particles
  • Low to medium viscosity (up to 20,000 mPas)
  • Thixotropic and dilatant
  • Shear-sensitive
  • Abrasive
  • Smearing or non-smearing
  • Aggressive (pH 0-14)
  • Adhesive

… such as natural and artificial polymers, anionic and cationic polyelectrolytes, iron and aluminum salt solutions (e.g. ferric chloride), lime water, water and wastewater samples, suspensions, organic and inorganic acids and bases, etc.
