Taco 1635dae20000000 In-line Cartridge Pump Less Motor

Product Description

The TACO 1635dae20000000 is an in-line cartridge pump from the 1600 Series, designed for closed-loop hydronic heating and cooling systems in commercial and light-industrial applications. It ships less motor, requiring the installer to supply the drive unit using the included 133-031 bracket. The casing, impeller, faceplate, and shaft are all stainless steel construction, while a cast iron bracket supports the rotating assembly. A 2-inch suction and 2-inch discharge configuration pairs with a 6.15-inch nominal impeller diameter. Maximum rated operating temperature is 250 degrees F. Licensed mechanical contractors and pipefitters install this pump in wet piping systems where long service intervals and straightforward maintenance are a priority.

The 1635dae20000000 is suited for in-line installation in hydronic heating, chilled water, and process fluid piping systems. Its rear pull-out design allows the motor and all rotating components to be removed for servicing without breaking the pipe connections. The replaceable bearing cartridge assembly isolates the ball bearings from system fluid temperatures, extending service life in high-temperature hydronic circuits. This pump is appropriate for both new construction and retrofit applications where a 2-inch in-line cartridge pump is specified.

Key Features

• Stainless steel casing, impeller, faceplate, and shaft for corrosion resistance in hydronic service
• Replaceable bearing cartridge assembly isolates ball bearings from system fluid temperatures
• Mechanical seal assembly: ceramic seat, carbon rotor, and EPT elastomers
• Rear pull-out design allows full motor and rotor removal without disturbing connected piping
• Ships less motor — installer supplies drive using the 133-031 bracket
• Rated for fluid temperatures up to 250 degrees F

Compatibility

Designed as an OEM-style in-line cartridge pump for hydronic systems requiring a 2-inch suction and 2-inch discharge configuration. Motor drive installation uses the 133-031 bracket supplied with the assembly.

Installation Notes

Installation should be performed by a licensed mechanical contractor or journeyman pipefitter in accordance with applicable local mechanical codes and ASME piping standards. Isolate and depressurize the system fully before removing or installing the pump assembly. Because this unit ships less motor, verify motor frame and coupling compatibility with the 133-031 bracket before starting installation. The rear pull-out feature allows servicing of rotating components without unbolting the pump flanges, but the system must still be shut down and drained to the pump elevation before service begins.
