ALM | ALP | In-Line Electric DAB Pumps

IN-LINE ELECTRIC PUMPS FOR HEATING, AIR CONDITIONING, REFRIGERATION, SOLAR, AND SANITARY SYSTEMS - SINGLE, THREADED Pumped liquid temperature range: from -15 °C to +120 °C - Maximum ambient temperature: +40 --°C APPLICATIONS
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
Cast iron pump body and motor support for ALM 500 and ALP 2000, bronze for ALM 200 and ALP 800.
1” 1/2 M-GAS suction and delivery ports for ALM 200 and ALP 800, and 2” M-GAS for ALM 500 and ALP 2000. Technopolymer impeller.
Carbon/ceramic mechanical seal.
CONSTRUCTION FEATURES OF THE MOTOR
External ventilation cooling, closed, asynchronous type, with four poles for the ALM version, and two poles for the ALP version.
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.
