Hayward D Series Vertical Seal-Less Immersible Pumps

D1 & DD1 Chemical Transfer Tote & Tank Pumps

The Hayward D1 and DD1 vertical centrifugal pumps are enhanced replacements for the earlier SS1 series tote pumps. These 1/8 HP seal-less immersible pumps are designed for reliable transfer and circulation of aggressive fluids from tanks and totes in industrial applications.

A heavy-duty TEFC motor with a ½-inch diameter extended stainless steel shaft and four precision-machined mounting pads provides stable, trouble-free performance. Precision-molded, dynamically balanced semi-open impellers use a unique tandem design that allows the pump to operate against a closed discharge valve without damage.

Key Features

• Available in CPVC, natural polypropylene, or PVDF for optimum chemical resistance
• Seal-less design — no seals to leak or replace
• PTFE fume barrier protects motor and bearings
• FPM elastomers standard (EPDM optional)
• No metal in contact with the fluid being pumped
• Virtually maintenance-free continuous-duty operation
• Non-overloading TEFC motors, epoxy painted
• Integral flange on pump body
• Optional inlet screens and in-tank filtration
