This Taco Series 1900, Model 1915-2P-PM pump is a close-coupled in-line pump with a 1-1/2" (40) mm suction and discharge. It has a 6.35" nominal impeller diameter and features NSF-61 certification, making it safe for use in drinking water systems. The casing and impeller are made of stainless steel, while the bracket has a stainless steel face plate and is cast iron. The first design pump has a stainless steel shaft without sleeve and uses ceramic seat seals with carbon rotor and EPT rubber. It can handle temperatures up to 250 Deg F. The pump is powered by a 7 1/2 HP motor that runs at 3450 RPM with premium efficiency, usable at 230/460/60/3 volts and at 208 volts. The motor part number is 1662-080, while DOE Info includes PEI = 0.87 , RPM = 3450 .
1900 Series Overview
1900 Series of close-coupled in-line pumps are manufactured by Taco Comfort Solutions, a global authority in designing and building heating and cooling systems since 1920. These pumps adhere to modern hydraulic performance and reliability benchmarks. The series incorporates five distinct models, with sizes spanning from 1-1/2" x 1-1/2" to 2" x 2". They offer a flow range from 10 to 250 GPM and can reach up to 160 feet of head capabilities.
These pumps are known for their compact, energy-efficient design, which allows for flexible installation in any part of the piping layout. They are self-supporting, eliminating the need for extra external support or strapping. They can be installed both horizontally or vertically.
1900 Series pumps are essentially maintenance-free, thanks to the motor's permanently sealed, grease-lubricated ball bearings. All models of the 1900 Series come equipped with standard ceramic seals, compatible with a wide range of application requirements.
