NEMO® C.Pro®

Universal Metering Pump

General

Universal Metering Pump

The NEMO® C.Pro® Metering Pump is a fully synthetic pump for the precise metering of a great variety of chemicals in environmental and chemical industries. Its synthetic construction makes it perfectly suited for the gentle and low-pulsation handling and metering of aggressive or non-aggressive chemicals.

With only six main parts, the NEMO® C.Pro® is economical and easy to service.

Features of the NEMO® C.Pro®

  • universally applicable for many types of media - even acids and bases
  • continuous low-pulsation handling unaffected by fluctuations in pressure and viscosity
  • capacity in proportion to rotation speed with precision metering over the entire speed range

The NEMO® C.Pro® offers you:

  • constant and nearly pulsation-free metering
  • metering in proportion to rotation speed
  • reversible direction
  • wide metering range
  • gentle product handling
  • easy serviceability

Technique

® C.Pro® Universal Metering Pump

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

2 Stator
The C.Pro® Pump comes 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 mechanical seal is positioned in the product flow, ensuring permanent flushing by the medium and preventing the sedimentation of solid materials. It 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" ANSI B16,5 150 LBS makes installation and removal.

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

6 Drive
Available drive options include an A-C gear motor, a 1200 rpm A-C motor with VFD controller or 600 rpm D-C motor with SCR controller.

The NEMO® C.Pro® offers you:

  • continuous and low-pulsation handling
  • metering in proportion to rotation speed
  • reversible direction of rotation and pumping
  • high suction and pressure capability
  • single-part rotating unit
  • mechanical seal in product flow
  • maintenance-free and serviceability
  • compact and economic design

Performance

  • flow rates from 0.02 to 265 gph / 0.1 to 1000 l/h
  • pressures up to 225 psi / 15 bar
  • temperature range from 0°F to 105°F / -17°C to 40°C
  • precision metering with deviation +/-1%

Applications

Dependable and efficient dosing – with the NEMO® CY C.Pro®

Dependable and efficient metering – with the NEMO® C.Pro®

The C.Pro® offers you a comprehensive solution for metering all types of chemicals in industry and environmental technology.

There are countless applications in many industries where chemicals with very different properties require precise metering. The C.Pro® performs this function not only with very high precision, but also gently and under low pulsation.

Wide Array of Applications
The NEMO® C.Pro® Progressing Cavity Pump is used primarily for products 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
  • sticky to dry
  • aggressive (pH 0 - 14)

… 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.

Additional Features:

  • maintenance-free and easy to service
  • compact and efficient

Wide Range of Capacities and Pressures

  • adjustable capacities from 0.02 to 265 gph
  • for differential pressures up to 225 psi
