6 Description of the product and accessories
6.1 General description
The system with its non-self-priming, vertically
(MV... or Helix V...) or horizontally (MH...) mounted
high-pressure multistage centrifugal pump is
supplied with all pipework installed as a compact
unit ready for connection. The only connections
that have to be made are for the inlet and pressure
pipes and the power mains connection. Systems
from series CO-1 (Fig. 1a and 1b) and COR-1
(Fig. 1d to 1f) are mounted on a steel base frame
with vibration absorbers. Systems from series
CO/T (Fig. 1e) are mounted on a plastic baseplate
together with a plastic break tank.
It may also be necessary to install accessories
ordered and supplied separately.
The systems CO-1 and COR-1 can be connected
to the water supply network either directly (dia-
gram in Fig. 7a) or indirectly (diagram in Fig. 7b).
When supplied with a self-priming pump (special
version), the system may only be connected to the
public water supply network indirectly (system
separation with a non-pressurised break tank).
You will find notes on the pump type used in the
attached installation and operating instructions
for the pump. The systems of type CO/T are pre-
pared for indirect connection to the public water
supply network by the integrated break tank with
level-dependent replenishment and system sepa-
ration.
