NSLH/V End Suction Centrifugal Monobloc Pump


DESMI NSLH/V end suction centrifugal monobloc pump

The design of the NSLH/V pumps is for medium/high flow capacities up to 6,600 US GPM & medium head up to 150mLC. The pump may be configured as vertical or horizontally. Both versions must be radially split, single stage centrifugal pump with connecting flanges according to international standards. The design of the pump needs to include mounting with electric motors having different international flange dimensions.

Material construction of the pump casings needs to be ductile cast iron GGG40 EN1561-GJL-400/DIN1693 for plain water, which shall be able to manage a working pressure of 16 bar (tested 1,5 x working pressure). For seawater applications, the pump construction of the casing shall be RG5 bronze EN1982 CC491K/DIN17656.

The pump casing shall be equipped with a NiAlBz EN1982 CC333G/DIN17656 replaceable sealing ring. Material of the shaft shall always be of high quality duplex stainless steel AISI329/1.4460.Contruction of the pump needs to be with no bearing in pumps in order to reduce service costs.

The pump needs to be fitted with dynamically balanced impellers acc. to ISO1940/1-1986 (E) G6.3 that incorporates advanced double-curved blades to ensure low NPSH-values and high efficiency resulting in lower energy consumption and therefore lower running costs.
The construction material of the impeller shall be NiAlBz EN1982 CC333G/DIN17656 (as standard) or duplex stainless steel AISI329/1.4460.

The seal type shall be a single acting, mechanical shaft seal, which seals off the liquid cavity at the motor shaft. The liquid temperature that the pump/seal can manage should at least be 250°F/121°C. For liquid temperature above 250°F/121°C, the seal needs to be balanced.
