Special features/product advantages
→ Compact system with outstanding price/performance ratio in compliance with the requirements of DIN 1988 → 2 – 4 horizontal MHI series full stainless steel high-pressure multistage centrifugal pumps switched in parallel → Easily adjustable and operationally reliable thanks to integrated ER 2 to ER 4 switchgears
Application
→ For fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems → Pumping of drinking water and process water, cooling water, fire water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities) or other types of industrial water that do not attack the materials either chemically or mechanically and do not contain abrasive or long-fibre constituents.
Equipment/function
→ 2-4 pumps per system → Components that come in contact with fluid are corrosion-resistant → Galvanized base frame with height-adjustable vibration damper for insulation against structure-borne noise → Pipework made of 1.4571 stainless steel → Gear-operated shut-off ball cock/annular shut-off valve on every pump, on the suction and pressure side → Non-return valve, pressure side → Diaphragm pressure vessel 8L, PN16, pressure side → Pressure sensor, on the discharge side → Optional pressure gauge (suction side) → Pressure gauge (discharge side) → Optional low-water cut-out switchgear
