In-line pumps designed for conditioning, heating, water recirculation in the presence of solar thermal panels (solar collectors) and for the circulation of drinkable hot water in residential building service and commercial building service.
Twin version available (the version with D letter).
All the pumps are ACS certified.

CONSTRUCTION FEATURES OF THE PUMP
Flanged suction and delivery ports (PN 10) with threaded holes for control pressure gauges.
Compatible with PN 16 counter-flanges for replacing pumps in existing systems.
Pump body and motor support in cast iron.
The twin versions are equipped with a swing valve incorporated in the delivery port to avoid the recirculation of water in the not working unit.
The pumps are equipped with a blind flange in the event if the maintenance of one of the two motors is required.
Technopolymer impeller, silicon carbide/silicon carbide seal.

CONSTRUCTION FEATURES OF THE MOTOR
Two-pole air-cooled asynchronous motor for KLP versions, four-pole for KLM. Motor shaft in AISI 316 stainless steel mounted on ball bearings.
Single-phase version with capacitor and built-in thermo-amperometric protection.
The user is responsible for the protection of the three-phase version.
