Installation and operating instructions SIL, DIL, PBS
All the pumps described are single-stage low-pressure centrifugal
pumps in compact construction design with a coupled motor. The
mechanical seal is maintenance-free. The pumps can be installed
both directly as a pipe installation pump in a sufficiently anchored
pipe or placed on a foundation base. Installation options depend on
the size of the pump. In conjunction with a control device (e.g. Salm-
son-CC/SC-HVAC-System), performance of the pumps can also be
continuously controlled. This allows optimisation of the pump output
for the demands of the installation and economically efficient pump
operation.
Version SIL:
The pump housing has an in-line design, i.e. the flanges on the suc-
tion and pressure sides lie along a centre line (Fig. 8). All pump hous-
ings are provided with pump support feet. Installation on a foundation
base is recommended for rated powers of 5.5 kW and higher.
Version DIL:
Two pumps are arranged in a shared housing (double pump). The
pump housing has an in-line design (Fig. 9). All pump housings are
provided with pump support feet. Installation on a foundation base is
recommended for rated powers of 4 kW and higher.
The base-load pump is only operated in control operation in conjunc-
tion with a control device. The second pump is available to fulfil full
load operation requirements as an auxiliary peak load. Moreover, the
second pump can adopt the reserve function in the event of a fault.
NOTE:
Blind flanges, which allow the motor impeller unit to be replaced even
in double pump housing, are available (see chapter 5.4 "Accessories"
on page 36) for all pump types/frame sizes in the DIL series (Fig. 9 to
the right). A drive can therefore remain in operation while replacing
the motor impeller unit.
NOTE:
To ensure operational standby of the standby pump, operate the
standby pump every 24 h at least once a week.
Version PBS:
Spiral housing pump with flange dimensions in accordance with
DIN EN 733 (Fig. 10). Depending on the construction:
Up to 4 kW motor power: pedestal screwed onto the pump or cast
feet on the pump housing.
From 5.5 kW motor power: motors with cast or screwed on feet.
Version in design B: With cast feet on the pump housing.
