Description
Pressure boosting system with non-self-priming stainless steel high-pressure multistage centrifugal pumps with speed-controlled motors.
-
Advantages
- Compact system with outstanding price/performance ratio due to MHIE series stainless steel high-pressure multistage centrifugal pumps with integrated air-cooled frequency converters
- Superproportionally large control range
- Integrated full motor protection with thermistor sensor (PTC)
- Automatic deactivation in the event of low water via the motor control electronics
- Maximum degree of control using the simple navigation and adjustment using rotary knob
- Tank with interconnecting pipework on a common base frame

Technical Features
Design
Pressure boosting system with 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 260 litre integrated breaktank with AB airgap, 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
- 260L WRAS approved GRP breaktank
- 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 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 switch

Construction
- Base frame: galvanised and provided with height-adjustable vibration absorbers for comprehensive insulation against structure-borne noise; other versions on request
- Tank: 260 litre GRP breaktank with AB airgap and WRAS approval
- Pipework: complete pipework made of brass and stainless steel, suitable for the connection of all piping materials used in building services; the pipework is dimensioned according to the overall hydraulic performance of the pressure boosting system
- Pumps: 1 pump from the MHIE 2.., 4.., 8.. series; adapted frequency converters on the pump motor enable continuous auto control for all pumps of these series; all pump components in contact with fluid are made of stainless steel
- Valves: each pump is fitted on the suction and pressure side with a shut-off valve with WRAS approval mark or annular shut-off valves and a pressure-side WRAS approved non-return valve
- Diaphragm pressure vessel: 8 l/PN 16 located on the discharge side with a butyl rubber diaphragm, completely safe in accordance with food safety laws; for testing and inspection purposes, with ball valve, with drain and throughflow fitting according to DIN 4807
- Pressure sensor: 4 to 20 mA, located on the discharge side for activating the central Comfort-Vario controller
- Pressure display: suction- and discharge-side pressure gauge (ø 63 mm)
