In-line constant pressure pump

Hot or cold water circulation pump with in-line ports, suitable for installation directly on the pipework of on civil and industrial heating, air conditioning, refrigeration, and sanitary water plants. Particularly versatile thanks to the use of the MCE/C inverter, offering performance features capable of automatically adapting to the different needs of the system, keeping a consistent differential pressure.

Operating range:
from 2 to 67 m3/h with head up to 13,7 metres.
Pumped liquid: clean, free of solids and abrasives, non - viscous, nonaggressive, non-crystallised and chemically neutral, with properties similar to water. 
Maximum, glycol content 30% (for other glycol percentages
contact Technical Support).
Pumped liquid temperature range: from -15 °C to +120°C.
Maximum ambient temperature: +40°C
Maximum operating pressure: 10 bar (1000 kPa).
Standard flanges:
DN 40, DN 50, DN 65, DN 80 - PN 6/PN 10 (4 holes)
Flanges on request: DN 80 - PN 16 (8 holes)
Counter flanges on request: threaded DN 40, DN 50, DN 65 - PN 6

Standard single-phase voltage: 1x220-240 V / 50-60 Hz
Special version on request:
three-phase 3x400 V / 50 Hz or three-phase 3x460 V / 60 Hz
Standard three-phase voltage: 3x400 V / 50 Hz
Special version on request: 3x460 V / 60 Hz. 

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 (KLME-KLPE) and in the twin (DKLME-DKLPE) 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.
