SKU CH-YDKE-KH08A

Handles elevator sump duties with a 1/2 HP motor at 230 V and an oil-probe sensor, moving 55 gpm at 10 ft head and reaching 37 ft maximum head

  • Delivers 55 gpm at 10 ft head for strong basement drainage
  • Maintains 39 gpm at 20 ft head for reliable mid-range lift
  • Provides 18 gpm at 30 ft head to handle taller discharge runs
  • Oil-probe sensor activates at 6 1/4 in for automatic water detection
  • Cast-iron body with carbon-ceramic seal resists wear in elevator sump pits

Elevator Sump Pump 1/2 HP 230V

The Liberty Pumps ELV280HV is a 1/2 HP elevator sump pump rated for 230V AC at 60 Hz. It uses an oil probe sensor with integral electrical connection for automatic level control. The cast iron body and polypropylene impeller suit commercial elevator pits that require reliable liquid removal.

Replaces manual or float-switched units

The oil probe sensor eliminates mechanical floats that can hang up in debris, making the jump worthwhile when pit fouling causes nuisance trips. Variable off-point adjustment lets the installer match the pump cycle to the specific pit geometry and inflow rate.

Limited by 37 ft maximum head

At 30 ft of head the flow drops to 18.0 gpm, and the pump reaches its shut-off at 37.0 ft, so it cannot serve high-rise elevator shafts with greater static lift. The 14 in minimum pit diameter and water depth also rule out smaller sump basins.

Questions about this item

What is the minimum sump pit diameter required for the ELV280HV pump?

The pump requires a minimum sump pit diameter of 14 inches and a minimum water depth of 14 inches for proper operation.

How is the oil probe sensor connected electrically on this elevator sump pump?

The switch electrical connection is integral to the pump body, so the sensor wiring is built in and does not require a separate external connection.

What materials are used in the shaft seal that will eventually need replacement?

The shaft seal uses carbon, ceramic, and nitrile rubber components that will wear over time and require periodic replacement.
