Wilo-Isar MODH1-E3
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. The multi-leader management ensures a high degree of operational reliability.
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

Design
Pressure-boosting system with two or three 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).
- 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
- 2 or 3 Medana CH3-LE pumps 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
- Multi-leader control via integrated frequency converters

Construction
- Base frame: electrogalvanised and 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: 2 or 3 pumps of the Medana CH3-LE- series 2.., 4.., 6.., 10.., 16.. connected 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 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, two 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 readout of the end pressure on the graphics display of the leader pump.
- Controller: the system is controlled by the frequency converters integrated in the pump.
