Product Introduction

This smallest DN50 pump uses a 0.75 kW motor and compact 150-class hydraulic for laboratory AHU coils and low-resistance branches. The inline format fits directly between matched flanges while the 16 bar working-pressure class supports common closed chilled-water systems.

Key Features

Small branch duty

The compact impeller and motor match a local coil circuit rather than a high-resistance distribution main.

Inline installation

Suction and discharge share the same pipe axis, reducing base and elbow requirements.

Closed-loop pressure rating

A 16 bar maximum working-pressure class fits many commercial chilled-water networks.

Applications

Small cleanroom chilled-water branches, laboratory AHU coils, terminal cooling circuits and local process heat exchangers.

Solutions for Your Application

An oversized high-head pump wastes energy and makes coil-valve control unstable.Select the 0.75 kW 150-class hydraulic at the verified branch flow and pressure loss.

Pipe strain can damage a compact inline pump.Support adjacent piping independently and align the DN50 flanges before tightening.

Available Options

Variable-speed drive, differential-pressure sensor, isolation valves, check valve, flexible connectors, insulation shell and monitoring contacts are available.
