Page M- MTH PUMPS M L Series Multistage Regenerative Turbine Pumps Capacities to 4 GPM Heads to Feet Single or Multi-stage Units (up to stages) Vertical Close Coupled Horizontal Close Coupled Horizontal Flexible Coupled M L SERIES PUMPS Vertical base mount and horizontal pedestal mounted multi-stage regenerative turbine pumps represent the most economical high performance alternative for low flow ( to 8 GPM) applications involving moderate to high pressures (heads to feet). By combining the latest concepts in hydraulic turbine pump design with precision computer controlled manufacturing, M Series pumps deliver high efficiency operation even at low NPSH. Costs are controlled by efficient manufacturing processes, use of standard motors, and highly optimized pump designs. Maintenance costs are kept to a minimum by combining an easily serviceable design with the use of high quality components to provide long life. Water Passage Design MTH masters one of the most critical design considerations of regenerative turbine pumps - the shaping of water passageways to achieve maximum capacity and pressure while minimizing horsepower requirements. By optimizing water passageway cross-sectional profiles for each impeller, MTH improves both efficiency and pressure in the M Series, and exceeds the standards realized by previous techniques. Impeller Profile One of the most notable improvements in regenerative turbine pump technology, incorporated in M Series pumps, involves the ability to determine the optimum impeller width and blade length. These factors have a significant effect on the required horsepower versus pressure curve for regenerative turbine pumps. By optimizing these for each pump, peak efficiency is improved and off peak horsepower requirements are reduced as well. Impeller Blades After the most favorable impeller profile has been determined for a particular water passageway crosssection, MTH calculates the number of blades needed to maximize the performance of that pump. The blade design in M Series pumps increases both efficiency and design pressure without incurring the manufacturing difficulties associated with producing contoured blade impellers. State-of-the-art computer controlled machines simplify manufacturing of the various MTH impellers utilized in the M Series. The result is a high performance pump providing efficiency characteristics exceeding those of much more expensive units. NPSH Requirements M Series regenerative turbine pumps meet low net positive suction head (NPSH) requirements without efficiency loss. This is achieved by keeping the inlet fluid velocity low and then gently accelerating to passageway velocities. Special ramps are responsible for this gentle fluid entry into the impeller blades and account for the high inlet efficiency of the M Series pumps. Copyright 8 MTH Tool Company, Inc. Dated January 8
Page M- MTH PUMPS M L Series Multistage Regenerative Turbine Pumps M L SERIES PUMPS Low NPSH Requirements L Series regenerative turbine pumps have exceptionally low NPSH requirements, making them ideally suited for applications where very little inlet head is available. STANDARD MATERIALS This reduced NPSHR provided by the L Series is obtained by using a first stage centrifugal style impeller with inlet flow paths shaped to maintain a constant fluid velocity. This reduces entry losses to the impeller as well as maintaining efficiency.
