Enquire About This Product

Description

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.
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.

Technical Features

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
Control via integrated frequency converter

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
