#4. SANIPACK Macerating Pump

Note: the wall carrier and the toilet bowl are supplied by other manufacturers such as American Standard and Geberit. Ask for Product No. 111.335.00.1 which is the Wall Frame that is designed for our Sanipack unit. This frame can be used with wall-hung toilets from such manufacturers are Porcher, Duravit and American Standard.

Since the reservoir, the macerating pump and the pipes are hidden from view, this type of installation gives you the lean and clean look of a European bathroom or powder room.

The Sanipack is simplicity itself to install; there are just four connections:

• The macerating/pump is connected to the discharge pipe coming from the wall hung 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 Sanipack 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 Sanipack activates a micro switch 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 9 feet and/or 100 feet horizontally. Once the water is discharged and the water level in the container goes down, the micro switch deactivates the unit until the flush is activated again. A normal operating cycle for Sanipack takes about 15 - 18 seconds depending upon the discharge pipe run configuration; power consumption is therefore minimal.

In addition to the toilet waste, Sanipack will also discharge gray wastewater from a variety of other sanitary fixtures, such as: a hand basin, shower, a bidet and a urinal. When adding a shower, 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 Sanipack 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 Sanipack can be turned either to the left or to the right, depending on the discharge installation.

The Sanipack is designed to provide vertical pumping up to 9 feet as well as a horizontal discharge, therefore a simple flapper style check 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 Sanipack is connected to, uses much less water than a regular toilet, it uses 6 liters (1.6 USG) of water per flush.
