Product Introduction

The three-pump package widens the manifold to DN100 and uses 5.5 kW motors on a 1170 x 1430 mm base. A third hydraulic provides staged capacity and a broader redundancy strategy for medium condenser-water or clean utility circulation.

Key Features

Three-stage capacity

The controller can add pumps as flow demand rises rather than forcing one unit across the entire operating range.

Flexible redundancy

The third pump can supply standby capacity or share duty depending on the verified peak load.

Wider common header

DN100 manifolding matches the greater combined flow and reduces package connection velocity.

Applications

Medium condenser-water systems, clean utility distribution, process cooling loops and controlled manufacturing plant rooms.

Solutions for Your Application

Two pumps cannot cover peak demand and preserve a standby unit at the same time.Use the three-pump set and allocate duty, assist and standby roles through the controller.

Combined flow exceeds a compact DN80 header's practical velocity.Use the DN100 manifold and verify connection pressure loss at the scheduled total flow.

Available Options

Stainless headers, pressure vessels, differential-pressure control, isolation and check valves, power options, alarms and remote communication are available.
