Pumps
Pump housing and impellers are constructed
from stainless steel and are designed for low
NPSH conditions to handle hot condensate
with the minimum of flooded suction. They
are directly coupled to TEFC motors having
class F insulation (class B temperature rise)
motor enclosure class IP55.
Pump fitting (fixed speed)
The motors and pumps are mounted under the
receiver and are each connected to suction
pipework incorporating isolation valves. Each
pump discharge is fitted with a non-return
valve suitable to connect to a PN16 flange.
Control
Receivers are fitted with Spirax Sarco Colima
Viscorol level indicators and SPDT switches
which provide duty/assist control. Included
is a control feature that alternates which
pump starts first. This ensures both pumps
will operate for the same duration over the
life of unit.
The control panel incorporates electrical
equipment suitable for 400 volt, 3 phase,
50 Hz, 4 wire supply. Control equipment is
installed in a pre-wired IP65 rated metal
enclosure. Connections for BMS interface
are provided to monitor pump run or tripped
condition.
