Other characteristics

• Booster unit version: RA (for applications with air cushion autoclaves).

• Main shut-off valves located on the suction and delivery of each pump, of the ball type with threaded connection.
• Check valve on the discharge side of each spring-type pump with threaded connection.
• For applications with air cushion autoclaves, they are mounted on the suction side and the unit is equipped with an air feeder connection for G 1/2“ threaded flexible hose (GMD20..RA series).
• AISI 304 stainless steel intake manifold with threaded ends. Threaded connection for water loading.
• AISI 304 stainless steel delivery manifold with threaded ends. It has R1" threaded connections with relative caps for connecting any 24 or 20 liter membrane vessels.
• Pressure gauge and 2 pressure switches Pressure gauge and 2 control pressure switches located on the delivery side of the group.
• Fittings vary in nickel-plated brass, galvanized steel or stainless steel depending on the version.
• Support base for pump group and panel support bracket in galvanized steel.
• Electrical control panel with IP54 protection rating.

Control panel

Three-phase power electrical panel, for the control and protection of a maximum of two three-phase electric pumps, with sheet steel case and IP54 protection degree.

Main features:

• Main door lock switch, fuse holders and fuses, starting contactors and thermal protections such as circuit breakers to protect each motor.
• Standard power supply voltage: 3x400Vac +/-10%, 50/60Hz. On request non-standard voltages, 3x230ca +/-10%, 3x440ca +/-10%, 3x460ca +/-10%, 3x480ca +/-10%, 50/60Hz.
• Transformer for low voltage auxiliary circuit; auxiliary voltage 24Vac.
• Lowara SM20 digital control unit (see fig.2), which offers the following functions:

- Signaling LEDs: line presence (ref.1), thermal protection intervention (ref.2), level alarm due to lack of water (ref.3), pump running (ref.4).
- Buttons (ref.5) and LED indicating automatic/manual operation (ref.6).
- Manual starting and stopping of pumps (one button for each pump) (ref.7).
- Automatic cascade control of the pumps via two pressure switches (one per pump).
- Pilot pump management by excluding cyclic inversion.
- Cyclic inversion function (excludable). It allows the automatic exchange of pumps at each start/stop cycle.
- Manual or excluded automatic operation selectors for each pump (inside the board). To be used only in the event of board failure to ensure pump operation.
- Arranged for protection against lack of water alternatively between: float, minimum pressure switch, external contact or electrode probes with sensitivity adjustment.
- Adjustable delay timer for the intervention of the protection against water shortage (inside the board); adjustable between 0..30sec.
- Adjustable operation extension timer for each pump (inside the board); adjustable between 0..100sec.
- Prepared for the installation, within the panel, of a relay card (optional) to relay signals of: pump 1, 2 running, manual mode, thermal alarm, lack of water alarm, line presence.

• Predisposition for the connection of the enabling from external contact or the pressure switch for maximum pressure protection.
