Overview

Compact system with optimal price-performance ratio thanks to the use of MHIE series stainless steel high-pressure centrifugal pumps with integrated air-cooled frequency converters
Extremely wide control range
Integrated full motor protection with thermal sensor (PTC)
Integrated dry run detection with automatic switch-off in the event of absence of water by controlling the motor electronics
ACS, KTW, WRAS approval for potable water on all components in contact with pumped fluid (EPDM)

Type

Pressure booster set with 2-3 parallel-coupled, normally aspirated stainless steel high-pressure multistage centrifugal pumps with integrated frequency converters

Application

Fully automatic water supply and pressure boosting from mains water supply or receiving tank for private, commercial, industrial and municipal applications (e.g. domestic, commercial and office buildings, hotels, hospitals, industrial facilities, water supply companies).

Materials

Single pump:

Impellers, sections, pump casing made of stainless steel 1.4301/1.4404
Stainless steel shaft 1.4404
EPDM (EP851)/FKM (Viton) seals
Tungsten carbide/graphite sliding mechanical seal
Bearings made of tungsten carbide
Pump support made of aluminum

Description/construction

Support frame: galvanized, with height-adjustable anti-vibration mounts, providing good isolation of casing noise. Other models available on request.
Pipe trains: complete stainless steel trains, suitable for the connection of all kinds of pipe materials used in building services equipment, designed in accordance with the total hydraulic capacity of the pressure booster unit.
Pumps: 2 to 3 pumps of the MHIE 2, 4, 8 and 16 series connected in parallel are used; frequency converters mounted on the pump motor enable infinitely variable regulation for each pump of these series. All pump parts in contact with the pumped liquid are made of stainless steel 1.4301/1.4404
Fittings: Every pump is equipped on the suction and delivery side with a ball check valve with DVGW approval mark or with globe valves and on the delivery side with a non-return valve with DVGW approval mark.
Diaphragm pressure vessel 8 l/PN 10, arranged on the discharge side, with a butyl rubber diaphragm in accordance with food safety laws; equipped with a shut-off ball valve for inspection and testing purposes, with a drainage system and flow fittings according to DIN 4807
Pressure sensor: 4 to 20 mA, arranged on the discharge side for controlling the central ECe controller
Pressure display: Pressure gauge ø 63 mm on the inlet and outlet pressure sides; additional digital indication of the outlet pressure on the alphanumeric LCD display of the ECe controller
Controller: The unit is equipped with an ECe controller as standard
