The single stage centrifugal GNHW series pumps are designed according to the ISO/API standards and manufactured with OH1/OH2 construction features by SEP PUMP. These process pumps with their approved quality, they cover a wide hydraulic range and various classifications of the standards.
High performance characteristics, long operational life, spare parts suplly / delivery /interchangibilty makes them dependable for critical application fileds.
GNHW series pumps can be manufactured with various material combinations classified by API standards according to operational conditions and tender clausses.
For the sealing system, depending on the process conditions, single or double sided ISO 21049/API 682 John Crane mechanical seals are used.
The base construction is possible in two ways either bottom mounting (OH1) or mid horizantal axis mounting (OH2).
They are end suction, single stage, radial / mixed flow closed impeller rotadynamic pumps and generally used in horizantal positioning.
Thanks to their design features, it is possible to disassemble the bearing support + shaft + impeller without disassembling the pump body from base. Although in our production standard, elactic couplings are used, if necessary to provide easy disasseble/ assemble, "spacer type" elastic couplings can be used.
