Standard flanges: DN 40, DN 50, DN 65, DN 80 - PN 6/PN 10 (4 holes).

Specification
  • Hot or cold water circulation pump with in-line ports, suitable for installation directly on the pipework of civil and industrial heating, air conditioning, refrigeration, and sanitary water systems.

    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 twin 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.

    CONSTRUCTION FEATURES OF THE MOTOR

    External ventilation cooling, closed, asynchronous type, with four poles for the KLM and DKLM versions, and two poles for the KLP and DKLP versions.

    Rotor running on permanently lubricated ball bearings, oversized to ensure low noise and durability.

    Standard built-in thermo-amperometric protection. Capacitor permanently fitted on single phase versions.

    For the protection of the three-phase motor, we recommend the use of remote overload cut-outs, in compliance with current local regulations.

    Construction according to CEI 2-3.

    Protection class: IP 55

    Insulation class: F

    Standard voltage: single-phase 220-240 V, 50 Hz - three-phase 230/400 V, 50 Hz

    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 in PN 10.

    welded DN 40, DN 50, DN 65, in PN 10/PN 16 (4 holes).

    welded DN 80 in PN 10/PN 16 (8 holes)

    Special executions on requests: alternative voltages and frequencies.
