Circulation pump for hot or cold water with in-line connectors, suitable for direct installation to pipes in civil and industrial heating, conditioning, cooling and domestic water systems.
Particularly versatile thanks to the use of the HYDRODRIVER, it offers performance features that automatically adapt to the various system requirements whilst keeping differential pressures constant.
Pump body and motor support in cast iron. Flanged suction and delivery connections in PN 10 with threaded holes for control pressure gauges. To make it easy to apply to existing systems, the pump is compatible with counterflanges in PN 6. Technopolymer impeller. Mechanical seal in carbon/ceramic. The pumps are available in the single version (KLME-KLPE) and in the twin version (DKLMEDKLPE). In the twin version, a clapet valve is incorporated in the suction connection to prevent water from recirculating while the unit is not operating. A blind flange is also supplied standard if one of the two motors needs servicing. The twin version allows pump operation to be alternated if a back-up unit or simultaneous operation of the two pumps is required.
Closed, asynchronous motor with external ventilation, four poles for KLME and DKLME and two poles for KLPE and DKLPE. Rotor mounted on oversized maintenance-free greased ball bearings to ensure silent running and long life. Incorporated overload cut-out. Built to IEC 2-3 standards
