What this pump handles

The Zoeller N153 is a submersible effluent pump built for sewage, septic and general liquid discharge. Its cast iron body and cast iron impeller are paired with a thermoplastic impeller for durability. The 1/2 HP motor draws 10.5A and is rated for continuous duty, making it suitable for demanding residential or light commercial waste‑water systems.

Check your electrical supply and piping

Verify that the circuit can deliver 10.5A at the required voltage before installation. Confirm the discharge pipe size matches the pump outlet and that the sump basin provides enough depth for full submersion. Ensure local codes permit this pump type for the intended effluent or sewage application.

Built‑in materials replace separate upgrades

The factory‑fitted cast iron housing and dual impeller design eliminate the need to source a separate heavy‑duty volute or corrosion‑resistant impeller. Continuous‑duty motor rating means no external thermal protection relay is required for normal operation. The desert beige finish is cosmetic only and does not affect performance.

Questions about this item

What comes with the Zoeller N153 and what must I buy separately?

The pump includes a cast iron body, a cast iron impeller and a thermoplastic impeller with a 1/2 HP motor rated at 10.5 A; discharge piping, check valve and electrical supply are not included.

Which version of the N153 should I choose for my septic system?

The N153 is offered in a single 1/2 HP, 10.5 A configuration, so there are no alternate capacities or voltages to select from.

What does the 10.5 A rating mean once the pump is installed?

The 10.5 A figure is the motor's running current draw, which determines the minimum circuit ampacity and breaker size required for the installation.
