    • No sheet metal parts to rust or corrode
    • All cast iron class 30 30000# tensile strength
    • Stainless steel screws, bolts, float rod, handle, guard and arm and seal assembly
    • Shaft seal – Carbon and ceramic rotary face seal, with stainless steel wetted parts
    • SAE 1117 carbon steel motor shaft (single seal models)
    • Upper and lower ball bearing running in bath of oil
    • Maximum temperature for sewage or dewatering: 130 °F (54 °C)
    • Oil-filled, hermetically-sealed, automatic reset thermal overload protected motor (1 Ph and auto 3 Ph)
    • All models available in 2” or 3” discharge
    • All models pass 2” (50 mm) spherical solids.
    • Automatic units available with float-operated, submersible mechanical switch**
    • Corrosion-resistant, powder coated epoxy finish
    • On point: 15-1/4” (38.7 cm)
    • Off point: 5-1/4” (13 cm)
    • Major width: 13-9/16” (34.4 cm) (single seal pumps)
    • Major height: 19-9/16” (49.7 cm) (single seal pumps)
    • Automatic or non-automatic with single seal
    • Non-automatic with double seals
    • 1 or 3 Ph motors available
    • See selection chart for specifications or specific models
    • 1 year limited warranty

    Models 282, 4282 double seal pumps (non-automatic only)

    • Protects motor from leaks
    • Improved bearing lubrication
    • Helps eliminate seal and bearing damage from dry runs
    • 416 stainless steel motor shaft
    • Major width: 13-9/16″ (34.4 cm)
    • Major height: 20-11/16″ (52.5 cm)

    Consult factory for special applications:

    • Three phase pumps are available in 200 V, 230 V, 460 V, or 575 V. 230 V three phase is available in automatic and non-automatic models.
    • Electrical alternators, for duplex systems, are available and supplied with a high water alarm, refer to FM0486.
    • Simplex Panel with high water alarm, refer to FM1596.
    • Variable level control switches are available for controlling 1 and 3 Ph systems
    • Double piggyback, variable level float switches are available for variable level long cycle controls
    • Longer cords are available in lengths of 25’ (8 m), 35’ (11 m) or 50’ (15 m)
    • Simplex and duplex basins are available
    • Refer to FM1922 and FM0806 for temperatures over 130 °F (54 °C)

    Notes
    The sizing of effluent systems normally requires variable level float(s) controls and properly sized basins to achieve required pumping cycles or dosing timers with non-automatic pumps.

    Reserve powered design.

    For unusual conditions a reserve safety factor is engineered into the design of every Zoeller® pump.

    * No UL Listing or CSA Certification for 200 V 1 Ph or Extra Duty (ED) pumps.

    ** Three phase automatic units available in single seal only.
