MTH All Bronze Regenerative Turbine Pump 1/2 HP
208-230/460V 3 Phase, TEFC# T31D-AB T21

Description

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.
