Profile: MTH Pumps is a commercial and industrial pump manufacturer serving a wide variety of markets and industries including boiler feed, condensate return, chillers/temperature controllers, water services, refrigeration, petroleum, as well as many chemical process applications. We develop a wide variety of mechanically sealed regenerative turbine, centrifugal, and other pumping products. Centrifugals feature stainless steel impellers and adjustment screws to fine tune, and occasionally renew performance. The stainless steel C series centrifugals are used as low pressure water boosters for small low-rise condominium complexes, where the high pressure of a turbine isn't necessary.
