Introduction de produit

This smallest factory set mounts two 4 kW vertical multistage pumps on a roughly 1150 x 1110 x 907 mm base. The DN80 manifold and twin-pump layout provide compact duty/assist or duty/standby circulation for clean-water condenser and utility loops.

Key Features

Twin-pump flexibility

Two hydraulics permit lead-lag operation, assisted peak flow or standby coverage according to the control sequence.

Compact factory skid

Pumps, manifold and controls are arranged on the smallest selected base for rapid utility connection.

Variable-speed pressure control

Drive control adjusts pump output as system demand changes instead of relying only on throttling.

Applications

Small redundant condenser-water circulation, clean utility loops, process cooling and compact plant-room pumping systems.

Solutions for Your Application

One small utility pump creates a complete circulation outage during service.Use the second pump as standby or share duty between both units according to the required resilience.

A custom field-built pump assembly consumes plant-room time and space.Use the compact factory manifold and base as a coordinated packaged connection point.

Options disponibles

Pressure sensors, isolation and non-return valves, expansion interface, stainless manifold, remote alarms, duty rotation and building-control communication can be selected.
