Through market research, Franklin Electric determined a large percentage of submersible nonclog pump sales went to industrial, commercial and municipal accounts. They used that information to develop the FPS NCX Series of non-clog pumps.

“In general, municipal applications tend to require hazardous location ratings for pumps,” says Kyle Johnson, product manager for Franklin Electric. “Franklin Electric saw this as a gap in their current product offerings that needed to be addressed.” 

Franklin Electric’s NCX Series stems from their NC Series, but adds a few upgrades to certify this series as explosion-proof by the CSA global safety and compliance organization. The idea was to upgrade components of the existing pumps and create a series for harsher industrial applications. 

“We strived to address as many aspects of the design as possible to meet common issues such as, heat, chemicals and abrasion, which can lead to premature failures,” Johnson says. “Implementing common construction upgrades helps ensure a reliable product across various applications.”

NCX pumps use Viton motor O-rings and a Class H motor insulation system to withstand high heat and provide chemical resistance. They also come standard with dual silicon carbide mechanical seals and a ductile iron impeller. Each pump is available in single or three-phase power options. Other specifications include a cast iron volute, seal chamber and housing around a continuous-duty pump, a 3- and 4-inch horizontal flange discharge and dual moisture-sensing probes. 

A key feature of NCX pumps brought over from the NC is the field-adjustable wear plate designed to simplify onsite maintenance. The wear plate provides adjustable clearance between the impeller and volute and eliminates the need and cost of replaceable wear rings. 

“This feature facilitates simplified, onsite maintenance allowing for a pump to be pulled, adjusted and reinstalled without needing to worry about having parts on hand or waiting for parts to arrive,” Johnson says. 866-271-2859;  www.franklinengineered.com
