CONSTRUCTION FEATURES OF THE PUMP
Pump body and motor support in cast iron. PN 10 flanged suction and delivery ports with threaded holes for control manometers. To make replacement in existing systems easier, the pump can
accept PN 6 counter flanges. Technopolymer impeller. Carbon/ceramic mechanical seal. The pumps are available both in the single (KLM-KLP) and in the twin (DKLM-DKLP) versions. For the single version a built in clapet valve in the delivery port is also included, to avoid water recirculation when the unit is idle. A blind flange is also supplied as a standard, to be used during maintenance of one of the two motors. The twin version gives the possibility of alternating the operation of the pumps when a backup unit is required, or to have the two pumps operating simultaneously.
