LMI RANGE: MAXIMUM ADAPTABILITY

The LMI range's electronically-controlled electromagnetic pumps are light and reliable. With more than 8,000 possible configurations, these pumps are covering various applications and processes.
LMI pumps are designed for use with the simplest as well as the most complex processes by means of their control interface, which uses a 4-20 mA signal or a physico-chemical controller. With their corrosion-resistant plastic housing and mechanical diaphragm liquid end, they form an accurate, rugged dosing solution that has been tried and tested over many years.
 

TYPICAL APPLICATIONS

  • Municipal water treatment at wastewater treatment or potabilisation plants: Coagulation/flocculation (injection of ferric chloride, aluminium sulphate, WAC, etc.), slurry treatment (injection of polymers), pH regulation (injection of acids and alkalis), etc.
  • Communal water treatment: Boiler water treatment (injection of disinfectant, film former, etc.), swimming pool water treatment (chlorine injection), rainwater marking (dye injection), chlorination (sodium hypochlorite injection), etc.
  • Industrial water treatment: Boiler water treatment (injection of biocide, scale inhibitor, corrosion inhibitor, etc.), industrial waste treatment (injection of acids and alkalis, etc.), process water treatment (food process water treatment for CIP, etc.)
  • Animal husbandry: treatment or post-weaning nursery (injection of drugs, vitamins in the drinking water)
  • Spa/Steam rooms: Injection of aromatic essential oils, perfumes, etc.
  • Other industries: Applications with low discharge pressures and precision dosing such as container filling

ADVANTAGES

  • Reliable and rugged
  • Fully compatible with most chemicals
  • Liquid ends for high viscosity (HV)
  • Accurate even at very low flow rates from 0 to 10 l/h
  • Flow rate adjustable from 1 to 1,000 ensures that process requirements are accurately met
  • Highly adaptable
  • Versatile programmable models
  • External control pulse multiplication and division for series AA9, B9 and C9
  • Microprocessor control of functions for series AA9, B9 and C9
  • Reduced maintenance: electromagnetic control requires no lubrication or cleaning
  • Proportional dosing
  • Protected electronics
  • Small footprint

TECHNICAL CARACTERISTICS

LMI pumps are available in 6 series with 5 different control modes, enabling you to find the model that meets your exact requirements.

5 control modes

Mode 0: Economical dosing
Flow rate variation from 20 to 100%
Stroke frequency fixed, stroke length manually adjustable
This is the simplest electromagnetic pump in the LMI range

Mode 1: Adjustable dosing
Flow rate variation from 1 to 100%
Stroke frequency and stroke length manually adjustable
This operating mode allows for a larger flow range

Mode 5: Proportional dosing
There are two usage options for this version:

  • - Stroke frequency and stroke length manually adjustable
  • - Adjustment controlled by a dry contact originating from a water meter or pulse generator

Pump stroke frequency varies automatically in relation to the emitter signal
Optional low level safety device to prevent loss of priming

Mode 7: Automated dosing
2 options:

  • Stroke frequency and stroke length manually adjustable
  • Pump stroke frequency varies automatically with the main flow rate. Control via dry contact or open collector originating from a water meter or pulse generator

Optional adapters MICROPACE® - multiply, divide, convertor 4-20mA, can be used to adapt the pump to different control modes
Optional low level safety device to prevent loss of priming
Electronically adjustable power control (Series B and C)

Mode 9: Microprocessor programmed dosing
Manually adjustable stroke length and frequency from 1 to 6,000 strokes per hour
Remote start/stop, proportional pulse control, integrated multiplier and divider, configurable 4-20 mA signal control, pulse copying, alarm display
Optional low level alarm and self-monitoring flow system
Electronically adjustable power control

4 materials of liquid ends are available

PVC:
This is the most economical material and is suitable for a wide range notably in the field of water treatment and agriculture

Acrylic:
This material has good compatibility with chlorine and fluorinated products. Thanks to its transparent nature, air bubbles and deposits can be seen and eliminated.

PVDF:
Suitable for use with concentrated acids and bases and oxidants

These standard liquid ends are supplemented by a range of special liquid ends allowing for the dosing of viscous products (polymers, silicon... up to 10,000 cP), stainless steel liquid ends for pressurised processes, PP liquid ends…
