Types of PCM pumps and their uses in industry applications

Progressive cavity pumps

Key features

A type of rotary volumetric pump, progressive cavity pumps feature a turning helical rotor which rotates within the helical stator. Turning the rotor into the stator, the honeycomb travels in a spiral motion along the axis of the pump transferring the product from the suction to the pump discharge. These pumps are pulsation-free and are equipped to handle higher pressure (a maximum of 24 bars), this makes them well-suited for steady flow industry jobs regardless of liquid viscosity.

Pump principle

Industry sector applications

PCPs are found in various industries, such as pulp and paper factories where they aid in the process of paper production. They are also prevalently used in mining and minerals processing plants, as well as chemicals treatment plants and waste water treatment facilities, where cake pumps are integral to the recovery of dewatered sludge and other highly viscos fluids.

Recommended uses

Available in a range of materials, this pump technology is suited to handle corrosive, abrasive and/or fragile fluids. Proficient at dispersing a wide viscosity of liquids, PCPs are suitable for a host of substances, including corrosive and fragile liquids holding solids, whilst avoiding any damage to the product. These waste-reducing pumps have also evolved to cater for a demand in environmentally friendly handling of industrial waste.

Advantages

  • Eco designed and low life cycle costs (LCC)
  • Simplified maintenance 
  • Flow rate is proportional to running speed
  • PCPs are reversible to suit your requirements

Performances

  • Pressure: up to 40 bars (standard pump)
  • Flowrate: from 3l/h to 250 m3/h
  • Particle sizes: up to 48 mm

Dosing pumps

Key features

Dosing pumps are small positive displacement pumps, designed for metering a wide range of liquids. Through the membrane connected to the piston, the reciprocating pump is able to fill and empty the pumphead successively thanks to an alternating movement. This technology is ideal for a precise dosing.

Pump principle

Industry sector applications

Dosing pumps are extremely flexible and have a variety of applications across different industries, including water treatment, industrial, manufacturing and mining. They can be used in extremely high temperatures, as well as for high pressure applications, which is why dosing pumps are often used to inject chemicals. Industry dosing pumps are available with additional options like foot valves and pulsations dampers making them ideal for metering an extensive range of products and substances across a host of sectors.

Recommended uses

Dosing pumps are adept at working with a spectrum of fluids (corrosive, abrasive, viscous), which makes them ideal for utilisation over a wide range of industries including the mining and minerals industry. Industry performance can be boosted with models boast silent operation and reduced mechanical and hydraulic shocks.

Advantages

  • Reliable metering
  • Easy to maintain
  • Able to accommodate dry running
  • Dosing pumps are extremely adaptable to your industry’s requirements

Performances

  • Pressure: up to 12 bars
  • Flowrate: from 0.5 l/h to 350 l/h per pumphead
  • Speed: 48 and 120 strokes / min
  • Accuracy: +/1 %

Peristaltic pumps

Key features

Sometimes known as hose pumps, peristaltic pumps are positive displacement pumps, a variety of rotary pump containing a collection of rollers that constrict as the hose turns. Peristaltic pumps have acquired their name from the peristaltic principle. This involves the turning and squeezing of a malleable elastomer hose which allows liquids to be transferred through the system. There are a number of options available when it comes to peristaltic pumps. These are available in high and low pressure options with the additional opportunity to choose between different flow rates like continual distribution or the disbursement of smaller quantities.

Pump principle

Industry sector applications

Peristaltic pumps are a notable and flexible pump which functions across a range of uses in the industry sector. Boasting the ability to handle even highly volatile substances, peristaltic pumps are adept at dosing and transferring in the chemicals and environment industries.

Recommended uses

Due to their versatility, peristaltic pumps appear in a variety of industrial applications and are equipped for use with harsh, corrosive and fragile liquids. These pumps can also handle solid particles, and are designed for use with sewage or chemicals like strong disinfectants and chlorine.

Advantages

  • No seal is needed to keep liquid within the tube so leakage is avoided
  • As only the hose comes into contact with the product, there is only one wearing part
  • Pump self-primes with no additional equipment required
  • Functions on dry run without risk of damage and is able to perform at different speed settings
  • Peristaltic pumps offer low LCC and simplified maintenance

Performances

  • Pressure: up to15 bars
  • Flowrate: from 10 l/h to 65 m3/h
  • Viscosity: 40 000 cPo
