Circulator for hot or cold water with in-line ports, suitable for installation directly on the pipes in civil and industrial heating air conditioning, refrigeration, and domestic water systems.
Extremely versatile thanks to the use of the MCE/C inverter, the circulator performance is such as to allow automatic adaptation to meet the various requirements of the system, while keeping pressure differentials unchanged.
Pump body and motor support in cast iron. PN 10 Flanged inlet and delivery mouths, fitted with threaded holes for pressure gauges. To facilitate interchangeability in existing installations, the pump is designed to accept PN 6 counterflanges. Impeller in technopolymer. Carbon/ceramic mechanical seal.
The pumps are available both in the single version (KLME-KLPE) and in the twin version (DKLME-DKLPE). An automatic clapet type valve is incorporated into the delivery mouth of the twin version in order to prevent water from recirculating while the unit is not working. In addition, a set of blank flanges is supplied for use when maintenance of one of the two motors is necessary.
The twin version makes it possible to alternate operation of the pumps when the back-up unit is requested, or simultaneous operation of the two pumps.
Four-pole totally enclosed asynchronous motor with fan cover cooling for versions KLME and DKLME and two pole motor for versions KLPE and DKLPE.
Rotor mounted on oversized greased sealed-for-life ball bearings to ensure silent running and long life.
Integral thermal and current overload protection.
