Centrifugal pumps according to API 610, API 685 (magnetic drive) latest editions.
All pump types according to API 610 designations available.
Pump type OH1: Single stage horizontal pump
Foot-mounted, single-stage overhung pumps type OH1.
Pump type OH2 (Ruhrpumpen SCE API Process Pump): Single stage horizontal pump
Centreline-mounted, single-stage overhung pumps pump type OH2, with bearing housing to absorb all forces imposed upon the pump shaft and maintain rotor position during operation. These pumps are mounted on a baseplate and are flexibly coupled to their drivers.
Pump type OH3 (Ruhrpumpen SPI Vertical In-Line Pump)
Vertical, in-line, single-stage overhung pumps with separate bearing brackets pump type OH3. These pumps have a bearing housing integral with the pump to absorb all pump loads. The driver is usually mounted on a support integral to the pump. The pumps and their drivers are flexibly coupled.
Pump type OH4 (IVP Vertical In-Line Pump)
Rigidly coupled, vertical, in-line, single-stage overhung pumps type OH4. Rigidly coupled pumps have their shaft rigidly coupled to the driver shaft.
Pump type OH5 (Ruhrpumpen SPN Vertical In-Line Pump)
Close-coupled, vertical, in-line, single-stage overhung pumps OH5. Close-coupled pumps have their impellers mounted directly on the driver shaft.
Pump type OH6 (Sundyne)
High-speed, integral, gear-driven, single-stage overhung pumps, type OH6. These pumps have a speed-increasing gearbox integral with the pump. The impeller is mounted directly to the gearbox output shaft. There is no coupling between the gearbox and pump; however, the gearbox is flexibly coupled to its driver. The pumps may be oriented vertically or horizontally.
Pump type BB1 (Ruhrpumpen ZW Horizontal Split Case Pump, ZMS Horizontal Split Case Pump): BB range
Axially split, one- and two-stage, between-bearings pumps type BB1.
Pump type BB2 (Ruhrpumpen RON Horizontal Process Pump, HVN Horizontal Double Suction Pump, J Line Horizontal Radially Split Pump): BB range
Radially split, one- and two-stage, between-bearings pumps type BB2.
Pump type BB3 (Ruhrpumpen HSM Multi-Stage Split Case Pump): BB range
Axially split, multistage, between-bearings pumps type BB3.
Pump type BB4 (Ruhrpumpen GP Ring-Section Type Pump): BB range
Single-casing, radially split, multistage, between-bearings pumps, type BB4. These pumps are also called ring-section pumps, segmental-ring pumps, or tie-rod pumps.
Pump type BB5 (Ruhrpumpen A-Line Barrel Pumps): BB range
Double-casing, radially split, multistage, between-bearings pumps (barrel pumps), type BB5.

Pump type VS3 (Ruhrpumpen VCT Vertical Circulating Pumps, VAF [PMR, POV, PV, PVD, VPO]): VS range
Wet pit, vertically suspended, single-casing axial-flow pumps with discharge through the column, type VS3.
Pump type VS4 (Ruhrpumpen VSP Chem Sump Pump): VS range
Vertically suspended, single-casing, volute, line-shaft-driven sump pumps type VS4.
Pump type VS5 (Ruhrpumpen VSP Chem Sump Pump): VS range
Vertically suspended, cantilever sump pumps, type VS5.
Pump type VS6 (Ruhrpumpen VLT Vertical Process Pump): VS range
