Single stage, open impeller centrifugal pump with a mechanical seal and integral gearbox. It will pump most animal waste slurries except long fibrous material which must first be run through a chopper. The pump includes a stationary knife which will slice through materials that build up at the eye of the impeller. The pump is very aggressive with the material being pumped. The pump volute and impeller are made from spheroidal graphite (SG) iron which is twice as strong and four times tougher than regular iron. The input speeds are the same as the NT120S above.
Single stage, closed impeller, centrifugal pump with a mechanical seal and integral gearbox. The wide design
impeller is capable of passing up to a maximum 5/8" solid. Four gearbox ratios are available. Two are designed for
PTO pumps with input speeds of 540rpm or 1000rpm. The other two are made to run direct from an engine.
