Your advantages
Wilo-ISAR MODH1 1-3

Your advantages

  • High operational reliability, thanks to system with one, two or three horizontal multistage CH1-L pumps with stainless steel hydraulics
  • Easy installation and maintenance thanks to special, flexibly adjustable connections to manifolds
  • Easy commissioning and operation with the Easy Controller
  • Drinking water approval (ACS and KTW) for pumps with components made of stainless steel that come into contact with the fluid
Series description
Wilo-ISAR MODH1 2-3

Design

Pressure-boosting system with 1, 2 or 3 non-self-priming stainless steel high-pressure multistage centrifugal pumps switched in parallel

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).
  • Pumping 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 – 2 or 3 CH1-L pumps per system
  • Components that come in contact with the fluid are corrosion-resistant
  • Electrogalvanized base frame with height-adjustable vibration absorbers for insulation against structure-borne noise
  • Stop valve on every pump on the suction and pressure sides
  • Non-return valve, pressure side
  • Pressure sensor, on the discharge side
  • Pressure gauge optional, on the suction side
  • Pressure gauge, discharge side
  • Low-water cut-out switchgear, optional
  • EC-control with IP54 plastic housing, consisting of an internal power supply unit, microprocessor, analogue and digital input and output modules

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: electrogalvanized and provided with height-adjustable vibration 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
  • Pumps: 1 – 2 or 3 pumps of the CH1-L series 2.., 4.., 6.., 10.., 16.. switched in parallel; 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 pressure side with a stop valve or with annular shut-off valves and a pressure-side non-return valve
  • Diaphragm pressure vessel: 8 l/PN 10 located on the discharge side with a butyl rubber diaphragm, completely safe in accordance with food safety laws; for testing and inspection purposes, with a ball valve, as well as drain and throughflow fitting according to DIN 4807
  • Pressure sensor: 4 to 20 mA, on the discharge side for activating the central EC-controller
  • Pressure indication: Pressure gauge (ø 63 mm) on the discharge side; additional digital display of the discharge pressure in the alphanumeric display of the EC-controller
  • Controller: the system is standard-equipped with an EC-controller

Delivery state

  • Factory-mounted, ready for connection pressure-boosting system checked for functionality and impermeability
