D23AB High Head Dewatering Pump

Short description

An automatic submersible sump pump that switches itself on and off with a built in float, clearing clean and grey water carrying soft solids up to 1 mm. It is often used in the second chamber of a septic system to pump settled effluent out to the field. Drop it in and let it manage the water level for you.

Why we like it

This is the set and forget sump pump. The float runs it only when water rises and shuts it off when the level drops, so it looks after a chamber or sump without anyone watching it. We reach for it for septic effluent transfer and clean or grey water sumps, anywhere a pump needs to run unattended.

Where it fits

This pump suits clean and grey water sumps and septic systems, most often the second chamber of a septic tank where it pumps settled effluent out to the disposal field. It handles fine soft solids up to 1 mm, so it is for water that has already settled, not raw dirty water. For dirty water with larger soft solids, the vortex D15VA or D40VA are the right pumps. For house water pressure, use a house pump instead.

Common questions

What is the D23AB for?
Clean and grey water sumps, and septic systems. Most commonly it sits in the second chamber of a septic tank and pumps settled effluent out to the disposal field. The float runs it automatically.

Is it automatic?
Yes. The built in float starts the pump when water rises to the switch on point and stops it when the level drops. No manual switching and no risk of forgetting it.

What can it pump?
Clean and grey water carrying fine soft solids up to 1 mm. It is for water that has already settled, not raw sewage or dirty water with larger or hard solids.

How is it different from the D15VA and D40VA?
Those are vortex pumps for dirty water with larger soft solids, 20 mm on the D15VA and 35 mm on the D40VA. The D23AB is for clean and grey water with fine solids to 1 mm, like settled septic effluent. All three are automatic, so choose by how dirty the water is.

What should we watch out for at install?
Keep the pump clear of the very bottom so it does not clog on settled silt, and check the float has room to swing. Do not run it dry. For the full rundown, follow our install guide.

What is the warranty in NZ?
Davey warrants this pump for 2 years. If something goes wrong, come to us first and we will do the legwork with Davey on your behalf. Davey are usually accommodating, but warranty cover is at their discretion and they may ask for photos of the install before approving a claim. The cleaner the install, the easier the claim.

Brochure

The Davey General Purpose Vortex Sump Pump range is designed for applications where reliability and blockage resistance are critical.

Using a semi vortex, open impeller centrifugal design, these pumps are able to pass soft solids in suspension while keeping debris away from the impeller. This significantly reduces the likelihood of pump or pipework blockages compared to standard centrifugal sump pumps.

Select models feature a recirculation port that keeps soft solids agitated within the sump, improving pumping performance in effluent and grey water applications. Double mechanical shaft seals in an oil bath provide excellent motor protection and long service life, with additional sand slinger seals offering further protection in abrasive environments.

The pump construction includes corrosion resistant 304 stainless steel motor shells, shafts, strainers, and fasteners, combined with a durable painted finish. Automatic resetting thermal overload protection is fitted to safeguard the motor during overload or blockage conditions.

These pumps are well suited to permanent installations and Davey recommends the use of slide rail kits for easy removal and servicing.

Key Features

  • Vortex open impeller design for improved solids handling
  • Less susceptible to blockages than standard sump pumps
  • Suitable for grey water and soft solids
  • Stainless steel shaft, motor shell, and fasteners
  • Thermal overload motor protection
  • Automatic and manual model options
  • Designed for commercial and domestic sump applications
