MTH T31 Series Regenerative Turbine Pumps

The T31 Series close-coupled regenerative turbine pumps represent the most economical, high performance alternative for low flow (1/2 to 9 GPM) applications involving moderate to high pressures (heads to 400 feet). By combining the latest concepts in hydraulic turbine pump design with precision computer controlled manufacturing, the T31 Series pumps deliver high efficiency pumping operation, even at low NPSH. Maintenance costs are kept to a minimum by combining an easily serviceable design with the use of high quality components to provide long life.

Features:

Self Adjusting Impeller 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. Mechanical Seals All bronze fitted pumps have Buna rubber, high temperature carbon and ceramic seats, while Stainless Steel pumps feature Viton rubber and ceramic seats. Optional seats and materials are available. 300 PSI Case Working Pressure Rigid structure is designed for maximum casing strength. Water Flinger A water flinger provides added protection to ball bearings in the event of seal leakage. 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. Simple Construction T31 Series pumps contain only three major components, allowing for easy service. Best Efficiency New pump designs optimize efficiency for each size. Non-Cavitating T31 Series pumps may be operated under adverse inlet conditions without audible or measurable cavitation. Low NPSH New inlet design provides superior fluid handling ability with low head inlet conditions. 100% Tested Every pump is fully tested to verify performance prior to shipment. Volatile Fluid Handling The turbine impeller handles vapors up to 20% by volume, minimizing the possibility of vapor lock. "O"Ring Gaskets "O"ring gaskets are used throughout the T31 Series pumps to assure positive sealing. Standard Motors Extended Reliability Motors Custom manufactured D3 motors feature a 304 stainless steel shaft and heavy duty ball bearing for extended life. Single phase ODP and 3 phase TEFC enclosures are standard, as well as a two-pole, 50Hz/60Hz ratings, and feature UL and CE marks for Worldwide use.
