Hot Water Recirculating Pump 110V with Timer 12.68 GPM 130W – 1" FNPT Flange

This hot water recirculating circulation pump is designed for continuous water circulation systems requiring stable flow and consistent temperature delivery. It operates on 110V power supply and is equipped with a built-in timer for scheduled operation control. The pump is suitable for both residential and light commercial applications where hot water circulation or pressure assistance is required. Model Number WW-Flange Timer Pump Flow Rate 12.68 Gallons Per Minute Material Type Cast Iron Power Source Corded Electric Voltage 110 Volts Color Red Maximum Lifting Height 288 Inches Product Dimensions 7.8"L x 5"W x 6"H Item Weight 6.9 Pounds Connection & Installation The pump uses a 1" FNPT flange connection design, which provides a stable mechanical joint for piping systems. Included installation accessories: 2 flange gaskets 4 mounting bolts This structure supports standard installation and allows for maintenance or disassembly when required. Timer Function The integrated timer allows users to set operating periods based on system requirements. It can be used to control circulation cycles, reducing unnecessary continuous operation and supporting scheduled hot water distribution in closed-loop systems. Construction & Materials Key internal and structural components include: Ceramic bearings for wear resistance PPO impeller for hydraulic stability Full copper coil motor for electrical conductivity and heat resistance Cast iron housing for structural durability These materials are selected for long-term operation in hot water circulation environments. Operating Characteristics The pump is designed for stable fluid movement in closed-loop systems. Supports continuous circulation under rated conditions Low vibration design during operation Suitable for systems requiring consistent flow delivery Application Scope This circulation pump can be used in the following systems: Residential hot water circulation systems Boiler systems Solar water heating systems Hydronic radiant floor heating systems Snow melting systems Central heating circulation loops Air conditioning water circulation systems General water pressurization and transfer systems Notes for Selection When selecting or installing the pump, system parameters such as pipe size, loop resistance, and required flow rate should be evaluated to ensure compatibility with the operating range.
