The Mechlion range of MLH, MLHI pumps are non-self-priming, horizontal, multistage, centrifugal pumps. Pump and motor are integrated in a compact and user-friendly design making the pumps suitable for installation in compact systems. The pump is fitted with a maintenance-free, mechanical shaft seal and through-going pump-motor shaft.

MLH: Complete hydraulics Chambers as well as all moving parts in contact with the pumped liquid are made of stainless steel. Discharge chamber, suction chamber and base plate are made of grey iron and CED coated for rust and corrosion prevention.

MLHI: Discharge chamber, suction chamber, base plate as well as all parts in contact with the pumped liquid are made of stainless steel. The motor is painted non-gloss black.

Features and Benefits

  • Compact and space saving design.
  • Very reliable and robust construction.
  • Highly energy efficient with IE2/IE3 class of motors.
  • Very low noise level.
  • Easy and simple installation.
  • Easy and minimum maintenance.
  • Suitable for drinking water.

Applications

The MLH and MLHI pumps are designed for small domestic and industrial systems.

  • Domestic
  • Liquid transfer and circulation of liquids within light industry and farming.
  • Pressure boosting.
  • Air-conditioning systems.
  • Specialized OEM equipment.

Pump

The MHM & MHMI series are non-self priming, horizontal multistage centrifugal.Pump is coupled with motor at the same shaft and mounted on a base-plate. The firendly design makes the pump suitable for installation in the small domestic or industrial water supply systems. The pump is fitted with a mechanical seal and through-going pump-motor shaft.

This discharge and suction chambers are made of cast iron. The other parts of pump in contact with the liquid are made of stainless steel.

MLHI: All parts of pump in contact with the liquid are made of stainless steel EPDM or Viton O-rings are available as standards.

Performance Range

Motor

The pump is fitted with a totally enclosed, fan-cooled, squirrel-cage motor.

  • Rated speed: 2850 rpm
  • Enclosure class: IP 54
  • Insulation class: F
  • Standard voltages: Single phase : 1 x 220-240 V, Three phase : 3 x 220-240/380-415 V

Operating Conditions

  • Liquid temperature range: 0°C to +90°C.
  • Max. ambient temperature: +55°C.

The maximum operating pressure depends on the temperature of the pumped liquid, see table

Max. operating pressure 10 kg/cm2 6 kg/cm2
MHM(I) 2,4 0deg C to + 40deg C +41deg C to + 90deg C
MHM(I) 8,12 0deg C to + 55deg C +56deg C to + 90deg C

Min.inlet pressure: According to the NPSH curve + a safety margin of 0.
Max.inlet pressure: Limited by the max. operating pressure.
