Product description

The SCE single stage API 610 is a single stage horizontal pump with enclosed impeller and seal chamber ready for API 682 mechanical seal. Ruhrpumpen has been a specialist on high efficiency centrifugal pumps with superior quality for a long time and as such Ruhrpumpen has a broad selection of overhung single stage centrifugal pumps.

RPs overhung pump product range complies to different industry standards such as API, ANSI, ISO and Hydraulic institute. SCE Single Stage Overhung Pump range covers for a horizontally mounted single stage centrifugal OH2 pump design according to API 610 oil and gas standard.

The volute is centre line mounted and with back pull out design for easy maintenance and replacement of impeller without dismounting the pump from pipeline if spacer shaft coupling is used.

Integrally cast end suction flange and centerline discharge flange are standard in 300# pressure class and available with 600# class flange if needed. The pumps can have single or double casing and can be offered with inducer for low NPSH operations to minimize the NPSHr value. SCE overhung pumps can reach the capacities up to 3200m3hr and head up to 480m. The pressure range of SCE single stage horizontal pump is up to 90 bar.

Bearing housing has increased stiffness for heavy duty applications, includes antifriction bearings (L10 lifetime even over API 610 requirement) and incorporates oil ring lubrication.

Shaft for API OH2 pumps are short and strong to ensure best L3/D4 stiffness ratio. SCE pumps are available in all material classes relevant for API 610 pumps. CRP process centrifugal pump is designed according to European standard ISO 2858 / 5199. CRP range of single stage centrifugal pump is available with ISO or ASME flanges, the pump is foot mounted and is a lighter version of SCE pump range.
