Wilo-Isar MODH1-E-1

High-quality pressure-boosting system with a compact design

Your advantages
Wilo-Isar MODH1-E1

High-quality pressure-boosting system with a compact design

Integrated protection functions enable the Wilo-Isar MODH1E to provide reliable water supply for various applications at all times. The protection functions include overload protection, dry-running protection and low-water cut-out switchgear with automatic deactivation. ​

Furthermore, significant energy savings are achieved through pressure-loss-optimised hydraulics as well as optimal load adjustment. ​​

The colour display enables optimal operating convenience by displaying plain text.


Your advantages

  • Compact system with a multistage stainless steel high-pressure multistage centrifugal pump from the Medana CH3-LE series with integrated air-cooled frequency converters with a large control range ​
  • Efficiency class IE5 and variable differential pressure Δp-v enable high efficiency
  • Colour display with plain text, simple navigation and settings via rotary knob ensure easy installation and operation​
  • Integrated safety features like low-water cut-out switchgear (WMS) provide a high degree of operational reliability​
  • Quick integration into building automation via optional CIF module​
  • Components that come in contact with the fluid are suitable for drinking water applications.
Series description
Wilo-ISAR MODH1-E-1

Design

Pressure-boosting system with one non-self-priming stainless steel high-pressure multistage centrifugal pump

Application

  • Fully automatic water supply and pressure boosting in inlet mode, either from the public water supply network or from a tank, for domestic, commercial, industrial and municipal applications (e.g. residential, office, administration buildings, hotels, hospitals, trades, industry, water supply companies).
  • Pumps drinking water, process water, cooling water or other industrial water, which does not affect the materials used, neither chemically nor mechanically, and does not have any abrasive or long-fibre constituents.

Equipment/function

  • 1 Medana CH3-LE pump per system
  • Components that come in contact with the fluid are corrosion-resistant
  • Electrogalvanised base frame with height-adjustable oscillation absorbers for insulation against structure-borne noise
  • Stop valve on every pump on the suction and discharge sides
  • Non-return valve, on the discharge side
  • Pressure sensor, on the end pressure side
  • Pressure gauge optional, on the suction side
  • Pressure gauge, on the end pressure side
  • Low-water cut-out switchgear, optional
  • Control via integrated frequency converter

Materials

Single pump:

  • Impellers, stage chambers and pump housing made of stainless steel 1.4301/1.4404
  • Shaft of stainless steel 1.4404
  • EPDM gasket (EP851)/FKM (Viton)
  • Mechanical seal made of tungsten carbide/carbon
  • Bearing of tungsten carbide
  • Pump support foot made of aluminium

Construction

  • Base frame: electrogalvanised and with height-adjustable oscillation absorbers for comprehensive insulation against structure-borne noise; other versions on request
  • Pipework: complete pipework made of stainless steel, suitable for the connection of all piping materials used in building services; the pipework dimensions must correspond to the overall hydraulic performance of the pressure-boosting system.
  • Pump: One pump from the Medana CH3-LE series 2.., 4.., 6.., 10.., 16..; all pump components that come in contact with the fluid are made of 1.4301/1.4404 stainless steel.
  • Valves: each pump is equipped on the suction and discharge side with a stop valve or with annular shut-off valves and a discharge-side non-return valve.
  • Diaphragm pressure vessel: 8 l/PN 10 on the end pressure side with butyl rubber diaphragm, completely safe according to the food safety regulations; ball valve and drain and throughflow fitting according to DIN 4807 for test and inspection purposes
  • Pressure sensors: 4 to 20 mA, one each on the suction and end pressure sides for pressure control by the integrated frequency converter.
  • Pressure indication: Pressure gauge (ø 63 mm) on the end pressure side; additional digital display of the end pressure in the graphics display of the pump
  • Controller: the control of the system is realised by the frequency converters integrated in the pump

Scope of delivery
