CMB Twin Booster Set by HAMSA Enviro Energy Solution

[The CM Twin Booster set consists of two identical Grundfos CM pumps connected in parallel and mounted on a common base frame and a control cabinet incorporating motor protection and controller.

A diaphragm tank must be included in the installation. Tank capacity can be decided based on the actual application and site requirement.

CM Twin booster set are supplied as complete, pre-assembled and tested system (without tank)]

Operation and functions

The pumps operate automatically according to system requirement by means of two pressure switches.

Function:

When a tap/valve is opened, water is drawn from the diaphragm tank (or bladder tank).

When the pressure drops to the first cut-in pressure, the first pump will start.

If the consumption is still rising and the pressure drops to the next cut-in pressure, the other pump will start.

When the water consumption falls, the discharge pressure rises to the first cut pressure and the controller will cut out one pump.

If the consumption is still falling, the second pump will finally fill the tank and then stop.

Grundfos controller CS 201 (single phase) or CS 200 (three phase) is used to control these pumps. Few of the

Features of the controller are as follows:

Automatically cascade control of the pumps by means of two pressure switches.

Automatic pump changeover at any start/stop cycle.

Pump and system monitoring functions:

Short-circuit protection by means of fuses.

Motor overload protection by means of thermal switch
built into the motor (lph only).

Dry running protection by means of an additional pressure switch or level switch (accessory).

Start and stop delays to prevent simultaneous
start/stopping of the two pumps (for CS 203 only).

Stop delay after reaching the respective cut-out pressure (for CS 203 only).
