Produkteinführung

This largest selected DN50 build uses a 2.2 kW three-phase motor and extended 240-class impeller. It supports higher-resistance chilled-water networks or multiple cleanroom coils while keeping the same nominal connection size as the two lower-head models.

Key Features

Greatest selected head

The 240-class hydraulic addresses long branches, multiple coils or greater control-valve resistance.

Larger motor frame

The 2.2 kW drive provides the input required by the extended impeller at higher duty points.

Variable network response

Speed control can reduce head and energy when fewer cleanroom coils call for flow.

Technische Parameter

Applications

Higher-resistance chilled-water networks, multiple cleanroom AHU coils, process cooling branches and medium central distribution loops.

Solutions for Your Application

The coil network requires more head than the 1.1 kW pump can deliver.Use the 240-class hydraulic only after confirming the design flow and full branch pressure loss.

High available head may cause noise and control-valve erosion at low load.Apply variable-speed differential-pressure control and balance the branches at commissioned flow.

Verfügbare Optionen

Integrated drive, pressure transducer, duty/standby controls, isolation, check valve, flexible connectors and condition monitoring are available.
