Our Products

Two pump ranges built for the jobs nobody else wants. Both made in Kyabram, both built to last.

How We Measure Pump Sizes

When we talk about column length, we’re measuring from the bottom of the pump casing up to the high water level mark — that’s the point just below the top bearing housing.

To pick the right size, measure your pit from the bottom up to where you want the maximum liquid level to sit. The pump casing needs to stay submerged at all times, and the liquid should never rise above the high water mark on the column. If you’re between sizes, go with the longer one.

DUMAC Filter-Cut Pump
Liquid Waste Disposal

Filter-Cut

Our flagship pump, in continuous production since 1964. A proper cutting pump with built-in agitation — it chops through waste and keeps everything moving. We make them in two outlet sizes and column lengths from 2’6″ right up to 12′, plus a horizontal option for different setups.

Column lengths: 2’6″ to 12′ (0.76m – 3.66m) + Horizontal

Motor range: 1.5kW – 18.5kW

Outlet sizes: 1.5″ (40mm) & 2″ (50mm) BSP

Reading Our Model Numbers

Our model numbers aren’t random — they tell you exactly what you’re getting. Here’s how to read them:

Filter-Cut

Format: [Length Prefix][Outlet Size]

  • SA = Short (2’6″ / 0.76m)
  • BA = Basic (3′ / 0.91m)
  • MA = Medium (4′ / 1.22m)
  • LA = Long (5′ / 1.52m)
  • XLA = Extra Long (6′ / 1.83m)
  • 40 = 1.5″ outlet, 50 = 2″ outlet

So an MA50 is a Medium (4′) with a 2″ outlet.

Ruffy

Format: [Length Prefix][F = Flange][50]

  • SR = Short (2’6″ / 0.76m)
  • BR = Basic (3′ / 0.91m)
  • CR = (3’6″ / 1.07m)
  • MR = Medium (4′ / 1.22m)
  • LR = Long (5′ / 1.52m)
  • XLR = Extra Long (6′ / 1.83m)

So an LRF50 is a Long (5′), Flange mount, 2″ outlet.
