  • 3 hp motor delivers strong grinding power
  • 230V AC three-phase supply suits commercial installations
  • Stainless steel body resists corrosion in wet environments
  • Ductile iron impeller handles solids without clogging
  • 57 gpm at 10 ft head moves high volumes efficiently

Heavy-Duty Grinder Pump for Demanding Drainage

The Dayton 11A343 is a 3 hp grinder pump built with a stainless steel body and ductile iron impeller for tough wastewater applications. It operates on 230V AC three-phase power drawing 9 A and includes a 16 ft power cord. The carbon, ceramic, and silicon carbide shaft seal is designed for durability in abrasive environments.

Upgrade from Lower-Capacity or Single-Phase Units

This pump delivers 57 gpm at 10 ft of head and maintains 38 gpm at 60 ft, outperforming smaller residential ejector pumps at higher lifts. The jump is worth it when moving solids-laden effluent over long runs or significant vertical rises where standard pumps lose pressure. No switch is included, allowing integration with existing or custom control panels.

Verify Electrical Supply and Control Requirements

Confirm your site provides 230V AC three-phase service at 60 Hz before ordering. You must supply a compatible pump control switch and electrical connection separately, as none are included. Ensure the discharge piping and basin dimensions match the pump's performance curve for the required head conditions.

Questions about this item

What discharge size does the Dayton 11A343 grinder pump need for mounting?

The pump has a 16 ft discharge head rating, so plan piping that matches that head pressure for proper fit.

How is the three-phase 230V AC motor wired during installation, and what step is often missed?

Connect the three-phase leads to a 230V AC supply with a compatible starter; the common miss is forgetting overload protection for the 9 A draw.

Which wear parts on the stainless-steel body and ductile-iron impeller will need replacement over time?

The carbon, ceramic and silicon-carbide shaft seal faces wear first; inspect them at each service interval and replace when leakage appears.
