Description of the pumps
All pumps dealt with herein are single-stage, low-
pressure centrifugal pumps of monoblock design
driven by coupled motor. The mechanical seal is
maintenance-free. The pumps can be installed eit-
her pipe-supported in sufficiently anchored pipe-
work or base-mounted on a plinth.
Its capacity can be infinitely varied if used in con-
junction with the respective control gear (Wilo-CR-
System). This will enable an optimum adaptation of
pump performance to actual load demands and an
economical pump operation.
– IL: The pump housing is of the inline design with
suction and discharge connection axially in line
(Fig.1). All pump housings are designed with the
possibility of base mounting on a plinth. Pumps
with a power 5,5 kW and above to be based
mounted.
– DL: Two pumps heads mounted in a common
housing (double-pump), the pump housing is
being of inline design (Fig. 2). All pump housings
are designed with the possibility of base moun-
ting on a plinth. Pumps with a power 4 kW and
above to be based mounted.
When used in conjunction with an automatic va-
riable speed controller only the base-duty pump
is operated variably. The second pump remains
available for parallel operation to cover peak-
load demand and additionally, for standby duty
to take over under fault conditions.
– BL: Pump with cast iron spiral pump housing and
flangedimensions to DIN EN 733 (Fig.3). Pump
with mounted fixing brace up to motor power 4
kW, 5,5kW and above with foot-mounted motor.
