MTH All Bronze T31D-AB T21 1/2 HP 208-230/460V, 3 Phase, TEFC motor, Regenerative Turbine Pump. The T31 Series close-coupled represent the most economical, high performance alternative for low flow (1 to 9 GPM) applications involving moderate to high pressures (heads to 300 feet).
T31 impellers utilize balancing holes to promote hydraulic self-centering and to eliminate the need for external adjustment. The impeller exerts no thrust load on the bearings, thereby extending service life. Self-centering is equally effective whether mounted in the horizontal or vertical position. The T31 series regenerative turbine pumps meet low net positive suction head (NPSH) requirements without efficiency loss. Also known as jockey pump. Used on many chillers.
Applications: Flooded Suction,
Boiler Feed, Chemical, Coolant and High Pressure.
End Suction/Top Discharge: T31 Series pumps are compact to allow installation in small areas. The discharge can be rotated to 90 degrees, 180 degrees and 270 degrees positions to facilitate the most convenient installation.
Temperature: 250 degrees F
Construction: Buna elastomers, high temperature carbon seals and ceramic seats.
Connections: 3/4" FNPT inlet and outlet.
Motor: T31 Series pumps utilize custom manufactured D3 motors that incorporate a 304 stainless steel shaft and an upgraded heavy-duty bearing. All D3 motors are 2-pole,
50/60Hz rated and feature UL and CE marks for Worldwide use, totally enclosed fan cooled (TEFC).
Electrical: 1/2 HP, 3450 RPM, 208-230/460 Volt, 3 Phase, 60 Hz.
