PUMP
The Dayliff DBE Booster is a compact water boosting unit for water supply in domestic
and commercial applications for single and two booster pump systems. The pump is
fitted with an integral variable speed controller that maintains pump output at
constant pressure (adjustable up to 5bar) with varying demand. The pump is compact
for simple installation, quiet with low operating noise level and of robust design for
long life. The speed controller maintains pump performance at maximum efficiency
thereby minimizing operating costs.
Particular features include:
• Booster output is adapted to demand by changing speed and number of
pumps in operation.
• Automatic pump alternation in multi-pump setup to ensure uniform operating
periods.
All hydraulic parts are made from AISI304 stainless steel, and the pump unit is
supplied with a 5-way connector, non-return valve and integrated pressure sensor.
For optimal operation, appropriately sized pressure tanks are required with 3L being
the minimum recommended size.
MOTOR
The pump is fitted with high efficiency IE4 Permanent Magnet variable speed motor
that incorporates thermal protection against motor overload and dry run protection
with auto-restart. The motor can be directly connected to the mains power supply
through appropriately sized FUSE or MCB.
