Sundyne HMP 7000 Overhung Impeller Integrally Geared Multi-Stage Pump

Heavy duty and extremely high pressure, the Sundyne API Style Integrally geared multi-stage pump

Sundyne integrally gear driven multi-stage pumps are utilized by process engineers to manufacture fertilizer, urea and PTA. These pumps are able to safely reach extremely high pressures and will run reliably for 5 years without an overhaul. Up to four overhung impeller pump stages are powered by a single gearbox and motor resulting in energy and space savings. Sundyne multi-stage pumps generally utilize only 25% of the space and require much less maintenance than between bearing pumps and generate extremely high pressures.

Unlike conventional multi-stage pumps, Sundyne computer tailored hydraulics place the B.E.P. (best efficiency point) at the rated point resulting in optimum efficiency.  An added benefit is reduced end-of-curve horsepower, allowing for smaller driver sizes resulting in energy savings.
