BMT and BMS hs pump installation
The inlet and outlet pipes are fitted with clamp liners for Victaulic
couplings.
To ensure correct installation, follow this procedure.
Step Description
The turbine is
driven by the high-
pressure
concentrate from
1 the membrane.
Connect the high-
pressure outlet to
the turbine inlet of
the BMT pump.
Connect the BMT
2
pump inlet.
Connect the BMT
3 pump and the BMS
hs pump.
Connect the hose
(∅300) to the outlet
of the turbine
housing with a
strap.
Lead the hose to a
drain tank, drain
4 channel or a similar
drain.
Fit the end of the
hose above the
highest possible
water level in the
drain. The hose
must be supported.
The concentrate from the turbine must flow freely to a drain under
all operating conditions. The height above the water level in the
drain must be at least 300 mm. The tube from the turbine to the
drain must have the same diameter in its entire length. The drain
must be larger than the tube and open so that the concentrate, a
mixture of air and water (foam), can escape freely.

The concentrate outlet must be free under all
operating conditions. If an outlet pipe is connected to
the concentrate outlet, this pipe must have an air
outlet.
3.3.4 BMSX system
A BMSX system consists of a BMS hs pump as high-pressure
pump and a BMS hp pump as booster pump. The pressure
exchanger of BMSX is installed in order to recover energy from
the high-pressure concentrate.
