Kwikflo KUS Series undersink pump station features and specifications

Greywater Lifting for Commercial Fixtures

Where a sink, basin or appliance sits below the sewer line, the KUS collects the greywater in its tank and pumps it up to the drain. The stainless steel models are built for hygiene-sensitive settings – dental surgeries, laboratories, cafes and commercial kitchens – where a wipe-clean, corrosion-resistant tank matters.

Poly or Stainless, 40L or 80L

The KUSP40 uses a 40L polyethylene tank – the value option for lighter-duty greywater. The KUS40 and KUS80 step up to 304 stainless steel at 40L and 80L, adding capacity and a heavy-duty, hygienic build. All three are pre-plumbed with valves and pipework and require venting.

Sealed Against Odour

A vent and compressible gasket seal the tank so odour is contained – important for an undersink unit installed inside a cabinet in a food or clinical space. A high-level alarm can be added to warn of a rising level before it becomes a problem.

Features

  • Pre-assembled undersink pump station
  • 40L poly, or 40L / 80L 304 stainless steel
  • Submersible pump – vortex, high-head or drainage type
  • Maximum head 7 or 11m (pump-dependent)
  • PVC ball and non-return valves, barrel unions
  • PVC interconnecting pipework
  • Vent and compressible gasket for odour control
  • High-level alarm option
  • Requires venting
  • Heavy-duty stainless models
