Lochinvar L100304110 Flange Pump Assembly 1.25 in 0-10 Vdc

Product Description

The LOCHINVAR L100304110 is a 1.25-inch flange pump assembly designed for hydronic heating systems that require variable-speed pump control. It accepts a 0-10 VDC control signal, allowing the pump speed to be modulated by a boiler or building automation controller. This assembly is intended for integration into hot water heating systems where precise flow management is required. Installation is typically performed by licensed HVAC technicians or plumbing professionals familiar with hydronic system commissioning.

This pump assembly is suited for residential and light commercial hydronic applications where variable-speed, electronically controlled pumping is specified. The 1.25-inch flange connection simplifies integration into existing or new piping configurations. Systems requiring analog 0-10 VDC pump control signals will find this assembly compatible with a wide range of modern boiler controls and building management inputs.

Key Features

• 1.25-inch flange connection for straightforward piping integration
• 0-10 VDC input signal supports variable-speed pump operation
