Grinding Unit: Model# 029
  • Manufacturer: Saniflo
  • Item SKU: 029
  • Finish: Gray
  • Collection: Sanicubic Classic
  • The Sanicubic Classic is a pre-assembled heavy-duty grinder pump that meets

    the demanding needs of commercial and residential sewage applications. The

    two-grinder system made of stainless steel liquefies solids into small particles

    prior to being passed through the 1-1/2" discharge. It is designed to handle

    multiple waste fixtures for applications such as residential single or group

    homes, commercial buildings, schools and many more.

    This new system consists of two 1-horsepower motors housed inside a compact but

    highly durable plastic enclosure. Each independently operating grinder has its

    own high-performance grinding system: a fast-rotating cutting blade to reduce

    solids in the wastewater stream from toilets, tubs and showers, sinks, washing

    machines, dishwashers, etc.

    The Sanicubic Classic operation is as simple as the installation. The effluent

    enters the pump through one of five different inlets - one on either side of the

    unit at the bottom and three along the top. The inlets can accommodate 1-1/2" or

    4" diameter pipes. As soon as the wastewater level reaches the trigger point,

    the pumping system activates. The effluent is then pumped out through 1-1/2"

    diameter rigid pipe connected on the top of the pump. Maximum pumping distances

    are 36 Ft vertically and/or 328 Ft horizontally.

    The inside of the Sanicubic Classic comprises of a couple of pressure switches

    and a circuit board assembly, which starts and stops the unit, and of a couple

    of motors, which drive the stainless steel cutting blades and the pump. Water

    and organic waste matter that enter the enclosure are reduced to slurry and are

    picked up by the impeller mounted beneath the motor.

    The two grinders inside the Sanicubic Classic are engineered to operate

    alternately. They each take turns handling the wastewater so that neither is

    more heavily used over time than the other. However, if either pump ceases to

    operate, the other pump will run full-time until servicing can eliminate the


    One of the many features of the Sanicubic Classic, is the smart-pump operation.

    A single pump is able to handle up to 50 gpm. If the incoming rate is higher

    than the discharge rate, the pump automatically signals the "overload" stage.

    This will activate the second pump and both pumps will operate simultaneously

    until the condition is alleviated. When both pumps are in operation, the

    discharge rate increases roughly 80%. In this event, a visual alarm LED on the

    unit will switch to red.

    The wastewater from other sanitary fixtures is discharged into the Sanicubic

    Classic via five 11/2-inch or 4" inlets, on either side of the housing and on the

    top of the enclosure. The internal discharge pipes come equipped with check

    valves that prevent back flow into the unit. Isolating valves (not supplied)

    must be installed on waste inlets and on the discharge pipe to ensure that any

    service/maintenance may be carried out safely.

    This unit has been designed with a 1-1/2" vent connection on the top of the

    enclosure. All plumbing codes require connection to a vent system. Please note

    that the vent system should be a two-way air vent. The use of mechanical vents,

    air admittance valves or similar devices are not permitted as these are

    considered one-way air vent systems.

    The Sanicubic Classic has been certified to American and Canadian Standards. US:

    CSA Certified & IAPMO (UPC) listed - ASME A112.3.4, CA: Macerating Standard CSA

Do you want to put a bathroom where conventional plumbing makes it difficult or even impossible? Then you need a Saniflo with its unique macerating system. Use that wasted space in the basement, under the stairs, even in a bedroom closet, without breaking the floor (or the bank). An extra bath, shower or powder room can fit in small spaces and increase the value of your house.
