Series 7100 Heavy Duty Wastewater Pumps

Job-Matched to Suit Your Needs!

Morris has teamed the NC, EC and MF Lines into the 7100 Series of Heavy Duty Wastewater Pumps to meet the requirements of today's municipal and industrial applications. Each line is designed for a different head range. If the pump application requires heads in the 100 to 200 ft plus TDH range, the NC line is the selection. The EC line is a group of medium head pumps that delivers flows between a 60 to a 120 foot range. The MF line is the best choice for high capacity/low head conditions covering from as low as 15 feet to over 65 ft.

These three lines are designed to be job matched to your specific needs. It is possible to have a pump from all three lines meet the same duty point. This flexibility allows selection and specification based on pump speed, efficiency, specific speed, driver size, wear, equipment life or cost.

This wide choice of sizes, configurations and materials of construction - coupled with a choice of three pump types designed for different, but overlapping, head ranges - means you can specify a Morris pump that will deliver superior performance yet still provide a cost effectiveness and operation life second to none.

A Morris professional will assist you in providing a comprehensive solution for today's wastewater equipment applications. The standard material selection for wastewater is cast gray iron due to its low cost and characteristic strength and durability. If mild corrosion or abrasion protection is required, a 3% nickel iron is suggested. While incrementally more expensive than standard grey iron, benefits in wear resistance and uniformity of castings make 3% nickel iron a logical choice for many wastewater applications. For high head/high pressure or heavy shock load applications Morris offers optional ductile iron construction for increased strength and overall toughness.

Exotic materials are a Morris specialty. Morris pumps are available in various grades of stainless steel and special metallurgies such as CD4MCu ("Duplex" stainless steel), High-Chrome Iron, Ni-Hard, Bronze, or other unique metals to meet your most demanding corrosive or abrasive applications.
