Taco 1635dae1l000000 Inline Pump 2 Inch Less Motor

Product Description

The TACO 1635dae1l000000 is a heavy-duty inline cartridge pump designed for commercial and industrial hydronic heating and cooling systems. This assembly ships without a motor and is configured to accept field-installed NEMA frame motors, giving installers flexibility in motor selection. The pump features a 2-inch suction port and a 2-inch discharge port, with a 6.15-inch nominal impeller diameter. The wetted components — casing, impeller, and face plate — are stainless steel construction. A cast iron bracket provides structural support. A mechanical seal assembly with a ceramic seat, carbon mating ring, and EPT elastomers allows operation up to 250 degrees F.

This pump is suited for in-line installation in closed-loop hydronic systems, including large residential and light commercial heating and cooling loops. The rear pull-out design is a key advantage in tight mechanical rooms: the motor and all rotating components can be removed for service without breaking the pipe connections. A replaceable bearing cartridge assembly with permanently sealed, grease-lubricated ball bearings and a stainless steel shaft simplifies scheduled maintenance. It fits into systems where a NEMA frame motor is already on hand or specified separately.

Compatibility

Designed as an OEM-style inline cartridge pump for hydronic systems requiring a TACO Series 1600 pump assembly with field-supplied NEMA frame motor.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor familiar with hydronic system piping and NEMA motor mounting requirements. Shut down and depressurize the hydronic system and isolate the pump with shutoff valves before any service work. Motor selection and wiring must comply with applicable NEC requirements and local mechanical codes. Confirm motor frame compatibility with the pump bracket before mounting.
