General characteristics Brand: Lowara Code: GMD 20 RA/5HM06P15T Data sheet Meaning of the product code: GMD 20: Fixed speed group (three-phase) RA: With inlet side check valve 5HM06P15T: Electric pump code Number of electric pumps: 2 Nominal power expressed in kilowatts: 1.5 kW Rated power expressed in horse power: 2 hp Technical specifications for a single electric pump Other characteristics Booster set version: RA (for applications with air cushion autoclaves). Main components Main shut-off valves located on the suction and delivery sides of each pump, ball type with threaded connection. Check valve on the discharge side of each pump of the spring-loaded type with threaded connection. For applications with air-cushion autoclaves, they are mounted on the suction side and the group is provided with an air feeder connection for a G 1/2“ threaded hose (GMD20..RA series). AISI 304 stainless steel intake manifold with threaded ends. Threaded connection for water loading. Delivery manifold in AISI 304 stainless steel 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 unit. Various fittings in nickel-plated brass, galvanized steel or stainless steel depending on the version. Support base for pump unit and switchboard bracket in galvanized steel. Electrical control panel with IP54 degree of protection. Control panel Three-phase power supply electric panel, for the control and protection of, at most, two three-phase electric pumps, with sheet steel case and IP54 degree of protection. Main features: Main door lock switch, fuse holders and fuses, starting contactors and thermal protections such as magnetothermal motor protectors for protection of 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 for lack of water (ref.3), pump running (ref.4). - Buttons (ref.5) and LED for automatic / manual operation (ref.6). - Start, manual stop of pumps (one key for each pump) (ref.7). - Automatic cascade control of the pumps via two pressure switches (one per pump). - Jockey pump management by excluding cyclic inversion. - Cyclic inversion function (can be excluded). It allows the automatic exchange of the pumps at each start/stop cycle. - Automatic, manual or excluded operation selectors for each pump (inside board). To be used only in case of board failure to ensure pump operation. - Prepared 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 lack of water (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, inside the switchboard, of a relay card (optional) for relaunching signals for: pump 1, 2 running, manual mode, thermal alarm, water shortage alarm, line presence. Arrangement for connection of enable from external contact or pressure switch for maximum pressure protection.
