Franklin Electric DB1 NPT Centrifugal Pump

The D-Series is a close-coupled centrifugal pump built around a heavy-duty cast iron body for durability in irrigation, commercial, construction, municipal, and light industrial service. Motors from 1/3 to 2 HP use 56C frames with a shaft coupling design for easy removal; larger models use JM frame motors with a shaft sleeve and O-ring arrangement that protects the shaft from damage.

This listing covers the DB1 hydraulic end with 1.5 x 1 NPT connections at 3600 RPM. Select horsepower, motor enclosure, and phase/voltage below — each combination is a distinct factory order number.

• Heavy-Duty Cast Iron Body — Cast iron construction throughout the volute for increased durability in continuous service.
• Silicon Brass Impeller — Enclosed impeller matched to the D-Series hydraulic family for efficient, stable performance.
• Easy Motor Removal — 56C frame motors (1/3–2 HP) use a shaft coupling design so the motor lifts off without disturbing the volute.
• Shaft Sleeve Protection — JM frame motors use a shaft sleeve and O-ring design for added protection against shaft damage.
• Mechanical Seal — Standard carbon/ceramic faces, nitrile elastomers, and 300 Series stainless components.
• ODP & TEFC Options — Single- or three-phase motors with open drip-proof or totally enclosed fan-cooled enclosures.
