Recommended services
Design
Pressure boosting system with 2 to 3 parallel-switched, non-self-priming stainless steel high-pressure multistage centrifugal pumps with speed-controlled motors
Application
Fully automatic water supply and pressure boosting in inlet mode from a tank, for domestic, commercial, industrial and municipal applications (e.g. residential, office, administration buildings, hotels, hospitals, trades, industry, water supply companies). Standby pump included in accordance with DIN 1988 and DIN EN 806.
Approved fluids are generally waters which do not attack the materials used, neither chemically nor mechanically, and do not contain any abrasive or long-fiber constituents like:
- Drinking water (check drinking water approvals in materials section)
- Cooling water
- Process water
- Firefighting water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities)
Equipment/function
- 2-3 pumps per system
- Infinitely variable control mode through the use of pumps with integrated frequency converters
- Components that come in contact with fluid are corrosion-resistant
- Galvanized base frame with height-adjustable vibration damper for insulation against structure-borne noise
- Shut-off valve at each pump, on the suction and pressure sides
- Non-return valve, pressure side
- Diaphragm pressure vessel 8 l, PN16, pressure side
- Pressure sensor, on the discharge side
- Pressure gauge, discharge side
- Low-water cut-out switchgear standard
