PRODUCT OVERVIEW

 

 

The MULTISAN-PRO pump is designed for the disposal of sewage, water soluble toilet paper and waste water. It is 

not designed 

as a sanitary waste disposal unit or a kitchen waste macerator unit,

 although it will pump the effluent from the latter. 

Avoid 

dumping in toilet or WHB or Sink non-organic products such as condoms, sanitary pads, wet wipes, tampons, nappies, 
sand, stones, tar, cement, coarse paper, non-water-soluble paper towels, cardboard, plastic bags, fat, oil etc. These 
products will cause the unit to malfunction or jam. Any damage to pump or any other property or person due to such 
jam is not covered under warranty.  

 
This 

unit is a secondary system

, it is not 

intended for use as the only means of effluent disposal from a dwelling

, and there 

must be an 

alternative gravity flow system available to the users of this pump.

 For complete household or commercial duties 

refer to our Wallace Pumps Sanipower, Saniboy or Sanistar range of packaged pump stations. 

 

The WALLACE MULTISAN-PRO collects the gravity fed waste liquid into its collection tank. When a set water level is reached, 
the micro pressure switch inside the collection tank automatically activates the powerful quiet pump equipped with a cutter blade 
and an open impeller to deliver the effluent under pressure to the desired location through a 32 mm internal diameter pipe. 
Because of the small pipe size, the delivery can be run virtually anywhere and in any direction, 
 - 

Through 

walls, 

 

- Through ceiling spaces, 

 

- Under floors, 

 

- Around and over obstacles. 

 
The unit enables the installation of a variety of equipment where this was previously impossible due to economic constraints, 
physical limitations, or because there was no unit available with adequate performance. The MULTISAN-PRO has been developed 
to overcome these problems, including 
 

- Below sewer-line installations, 

 

- Where gravity fall is not possible, 

 

- Physical restrictions, e.g. concrete walls or concrete floors, 

 

- Where new pipes cannot be run under the floor, such as concrete floors, 

 

- Where large diameter 100 mm gravity lines are not appropriate for the location, 

 

- And many other situations. 

 
 
 
 

4.  APPLICATIONS

 

 

The MULTISAN-PRO collects and automatically pumps away toilet waste water from the following and many other typical 
applications: 
 

- Basement toilet and bathroom facilities 

 

 

- Secondary amenities in factories built on concrete floor slabs 

 

- Relocated bathrooms where gravity fall to existing sewer connections is not possible 

 

- Re-developed apartment blocks in inner cities 

 

- Master bedroom ensuites  

 

- Executive bathrooms 

 
In addition to the toilet pan (only one allowed per installation), you can connect one or a combination of the following additional 
fixtures or appliances: 
 

- Laundry tubs, 

 

- Domestic clothes washing machines, 

 

- Domestic sinks with or without waste disposal units, 

 

- Domestic dishwashing machines, 

 

- Bar facilities without high temp water discharging Glass washers or commercial dishwashers 

 

- Bath, shower, vanity, 

 
PROVIDED THAT  
- In a multi-storey construction, they are all located on the same floor level as the MULTISAN-PRO. 
- Maximum temperatures in the collection 

tank are 40

C continuous and 60

C intermittent

- No unwarranted items (listed under “Section 2 Product Overview”) are discharged into unit 
- The max flow of water discharged into the unit should not exceed 70 L/min

.

  

   For larger flows, contact Wallace Pumps for advice.
