2010.10.01 - Product Improvement Notice

In an ongoing effort to improve our products, MTH will soon begin replacing electroless nickel plating with Teflon coating on T51 and T41 iron pump components. The Teflon coating has been selected for its corrosion resistance, reduced startup friction, and to some degree, improvement of abrasion and wear resistance. MTH has completed side-by-side testing of our pumps for performance and shelf life using today’s electroless nickel coating, as well as Teflon, hard chrome, black oxide, and natural (no coatings). Of those, we found that the best results came from the Teflon coating. The changeover should begin in the next couple of weeks and will continue over several months as existing stock is replaced. Please feel free to contact the factory for more information.

2010.07.29 - Product Update Announcement

MTH T Series Pumps have a new look!

Through years of production, our engineers have developed a new method of pouring our stainless steel castings on our T Series Pumps that allow for a more consistent casting. While this new look does not effect dimensions or performance, we felt it was our responsibility to let you know that we are committed to bring you the best possible products in the market.

At this Time, only T31 Series and T51 Series are utilizing this new casting and will be filtered in as our old stock is depleted.

T31 Current Design	T31 New Casting Design

Although performance and dimensions remain unchanged, there are major advantages to this casting change in the T51 Series. The flat area along the top of the new cover allows for top mounted suction or gas/liquid injection port options. The option of a top suction inlet instead of the front inlet makes the pump more universally adaptable for different installation configurations. The optional vent port on the top can be utilized as an air vent to ensure the pump is free of air prior to initial start-up, suction pressure readings, or gas injection.

2010.02.12 - New Product Announcement

For years, MTH has offered the 150/160/170 series regenerative turbine pumps in all of our available materials except the 170 family (a close relative to the 150/160). The 170 series has never been offered in stainless steel...

Until Now!!!

We are proud to offer the 170K model in single stage up to four stage configurations, as well as the low NPSH 270 inducer option.

We are pretty excited about this offering! If you look at the performance curve, you will see that the 170K can often be selected where a 170J or H may have been used (again, only the K will be available for the immediate future), so we are pleased with how this will fill a previous void for stainless steel pumps in the MTH lineup! The 174K (our largest model) can reach heads up to 1150 feet and produce capacities to 150 gallons per minute.
