SANIPLUS - toilet and pump
The Saniplus is a
system that is used to install a complete bathroom up to 12 feet below the sewer
line, or even up to 150 feet away from a soil stack. The
Saniplus can handle up to four fixtures, toilet, hand basin, shower and bathtub.
The
Saniplus is simplicity itself to install; there are just four connections.
The
macerating/pump is connected to the spigot of a horizontal outlet toilet.
The toilet
tank is connected to the water supply.
The macerating/pump
is connected to the small diameter discharge pipe work.
The macerating/pump
is connected to the electrical supply.
The inside of
the Saniplus comprises of a pressure chamber, which starts and stops the
unit,
and the motor, which drives the stainless steel macerator
blades
and the pump.
When the flush
is activated, the water flowing into the Saniplus activates a microswitch
in the pressure chamber, which in turn starts
the motor.
The motor
is sealed for life in oil filled enclosure. A common spindle drives
the impeller and the macerator blades. The moving parts therefore are kept
to an absolute
minimum. Water and organic waste matter, enter the chamber and are
reduced
to slurry as the macerator blades rotate at 3600 RPM. The centrifugal
force causes
the reduced solids to be ejected through a grill into the container
where it is picked up by the impeller pump mounted beneath the motor. The
pump
operates
at 10 PSI and pumps the effluent upward to 12 feet and/or 150 feet
horizontally. Once the water is discharged and the water level in the container
goes
down, the microswitch deactivates the unit until the flush is activated
again.
A normal operating cycle for Saniplus takes about 15 - 18 seconds depending
upon the discharge
pipe run configuration; power consumption is therefore minimal.
In addition
to the toilet waste, Saniplus will also discharge gray wastewater from
a variety of other sanitary fixtures, such as: a hand
basin, a bath,
a bidet and a urinal. When adding a bathtub, a base will have to
be constructed, made
out of 2" x 6" on edge, to allow for the installation of
a P-trap and some gravity flow towards the pump unit.
The
wastewater from other sanitary fixtures is discharged into Saniplus via two
1 1/2-inch inlets, on either side of the housing. Either
one or both
inlets can
be used as required. The discharge elbow on top of the Saniplus
can be turned either to the left or to the right, depending on the discharge
installation.
The Saniplus automatically
adjust the input rate from other sanitary
fixtures, always giving priority to the discharge water of the
toilet. Inlet valves
operated by a simple float mechanism achieve this. For example,
if the bath is being emptied
and the toilet is flushed simultaneously, the inrush of water
from the toilet into the container slows down or stops the discharge
from other
fixtures
for a few seconds, until the waste from the toilet has been dealt
with. As the toilet
water is discharged and the level in the container goes down
the float valves open and the discharge from the other fixtures resumes.
The
Saniplus is designed to provide vertical pumping up to 12 feet as well as
a horizontal discharge, therefore a simple ball non-return
valve
is
incorporated. It has now become possible to install a complete
bathroom where previously
this
would have been impossible or where considerable capital equipment
and structural work would have been necessary.
The water closet
the Saniplus is connected to, uses much less water than a regular toilet,
it uses 6 liters (1.6 USG) of water
per
flush.
