Goulds Pump 1SVR90 1SV Repair Stack

The Goulds 1SVR90 is a Repair Stack for the 9-stage 1SV e-SV Series Vertical Multistage Centrifugal Pump, 9 stages: 9 impellers in 2+7, 1 intermediate bearing, 7 plain diffusers, 1 with bushing, 1 initial stage, 1 final diffuser. To simplify maintenance, Goulds makes a complete repair stack assembly for quick and efficient installation and repair. This repair stack replaces the whole impeller and diffuser stack of a 9-stage 1SV e-SV with a factory-built stack: 9 stages: 9 impellers in 2+7, 1 intermediate bearing, 7 plain diffusers, 1 with bushing, 1 initial stage, 1 final diffuser. It is the same stack in every frame and every connection configuration of the 9-stage 1SV. It fits the 9-stage 1SV liquid ends 1SV9FA30, 1SV9FA40, 1SV9GA30, 1SV9GA40, 1SV9NA30, 1SV9NA40, 1SV9TA30 and 1SV9TA40. The picture is representative of the e-SV series and is not a photograph of this exact model; the number of stages, the connection type and the motor vary by model.
