Goulds Water Technology NPV and SHV Series pumps are vertically immersed, end-suction designed pumps for general liquid transfer service, machine tool coolant, parts washer, filtration, waste treatment and OEM applications. Liquid-end construction is all AISI 300 series stainless steel. These pumps are not designed for applications requiring ANSI, FDA or NSF ratings and are not recommended for use in highly abrasive services such as grinding. Impellers are available in enclosed and open configurations depending on the model. Enclosed impeller versions of the NPV are fitted with a diffuser for high efficiency and for negligible radial shaft loading. NPV units have NEMA 56J motors with C-face mounting and threaded shaft extensions. SHV units have NEMA standard JM frame motors.
