Hayward R Series Mag-Drive Centrifugal Pumps

Seal-Less End-Suction Pumps for Aggressive Fluids & Corrosive Environments

Hayward R Series all-plastic, corrosion-resistant magnetic drive centrifugal pumps are designed for aggressive fluids and demanding industrial environments that attack metal. The thick-wall glass-reinforced polypropylene (GFPP) or carbon-reinforced ETFE pump body, combined with a seal-less magnetic drive, ensures process fluid never contacts metal and eliminates failures caused by rust or corrosion.

These end-suction pumps deliver a zero-emission, leak-proof design that removes the cost and downtime of mechanical seal replacements. Pump sizes range from 1/3 HP to 5 HP with flow rates from 5 to 140 GPM and heads up to 141 feet. A two-year warranty is standard.

Key Features

• Seal-less magnetic drive — leak-proof, zero-emission design

• Available in glass-reinforced polypropylene (GFPP) or carbon-reinforced ETFE
• Ceramic shaft with PTFE bushing
• Double-supported, non-cantilevered shaft
• Rifled impeller bushing dissipates heat
• Anti-air-lock mechanism
• Low-friction operation and reduced energy consumption
• Easy maintenance — no special tools required
• Exclusive two-year warranty
