6. Product introduction
6.1 Product description
The pumps are submersible booster pumps for
pumping clean water. The pumps are especially
suitable for rainwater applications and small private
wells.
The pumps are available in two main versions:
•
with integrated inlet strainer with 1 mm mesh
•
with side inlet which includes a flexible inlet hose
with floating inlet strainer with 1 mm mesh.
Both versions are available with or without float
switch. The float switch can be used for automatic
operation or dry-running protection of the pump.
SB pumps must be connected to an external
controller. We recommend a Grundfos Pressure
Manager: net.grundfos.com/qr/i/97506325
The SBA pump is a complete submersible booster
pump. The pump has a built-in control unit,
eliminating the need for a controller.
The pump has built-in protection against
overheating.
6.2 SBA functions
The built-in control unit incorporates dry-running
protection that automatically stops the pump in case
of dry running.
The dry-running protection functions differently
during priming and operation.
6.2.1 Dry running during priming
If the control unit does not detect any pressure and
flow within 5 minutes after it has been connected to a
power supply and the pump has started, the dry-
running function is activated and the pump stops.
6.2.2 Dry running during operation
If the control unit does not detect any pressure and
flow within 40 seconds during normal operation, the
dry-running function is activated and the pumps
stops.
6.2.3 Resetting of dry-running alarm
If a dry-running alarm has been activated, you can
restart the pump manually by switching off the power
supply, wait for 2 minutes and reconnecting power. If
the control unit does not detect any pressure and
flow within 40 seconds after restarting, the dry-
running alarm is reactivated.
6.3 Pumped liquids
Mains water and rainwater.
Thin, clean, non-aggressive and non-explosive
liquids, not containing solid particles or fibres that
may attack the pump mechanically or chemically.
Do not lift the product by the power supply
cable. Lift the product by means of a rope.
