Ruhrpumpen / Ruhrpumpen Group Industrial Pumps: API 610 Centrifugal and Reciprocating Units
Engineered centrifugal overhung and between bearings process pumps, API 674 plunger pumps, and vertical turbine units from Ruhrpumpen / Ruhrpumpen Group. Global engineering selection and industrial pumping equipment supply.
Overhung Centrifugal Process Pumps Ruhrpumpen SCE to API 610
Ruhrpumpen SCE series heavy-duty overhung pumps are engineered to API 610 (OH2) with centerline mounting. Delivering capacities up to 3200 m³/h and heads up to 480 m, they handle casing pressures up to 90 bar. The back pull-out design simplifies rotor servicing without piping removal.
- Series SCE, SPI, SPN, CPP, CPO
- Capacity up to 3200 m³/h, head 480 m
- Casing pressure ratings up to 90 bar
- Impellers, shafts, bearings for OH2
Horizontal Between Bearings Pumps Ruhrpumpen GP and HSM (BB1–BB5)
Ruhrpumpen GP, GPA, and HSM between bearings pumps comply with API 610 BB1 through BB5 standards. They generate pressures up to 300 bar and flows up to 6000 m³/h for pipelines and boiler feed duties. The dual-bearing design minimizes shaft deflection and seal wear.
- Series GP, GPA, HSM, JTN, ZM, A-Line
- Configurations API 610 BB1 to BB5
- Pressures up to 300 bar, flow 6000 m³/h
- Ring sections, wear rings, shaft sleeves
Vertical Turbine and Sump Pumps Ruhrpumpen VTP (VS1–VS6)
Ruhrpumpen VTP vertical turbine pumps and VSP sump pumps comply with API 610 (VS1 through VS6) specifications. Delivering flows up to 13,600 m³/h and setting depths to 100 m, they handle cooling and intake duties. Diffuser bowl stages ensure dependable hydraulic efficiency.
- Series VTP, VCT, DSV, DX, VSP, VAF
- Flow up to 13,600 m³/h, head up to 500 m
- Configurations API 610 VS1, VS2, VS4, VS6
- Diffuser bowls, line shafts, column pipes
Reciprocating Plunger Pumps API 674 RDP and Mag-Drive SCE-M
Ruhrpumpen RDP reciprocating plunger pumps meet API 674 in triplex and quintuplex configurations for pressures up to 1500 bar. Sealless magnetic drive pumps SCE-M meet API 685 for complete emission containment. Systems serve methanol injection and toxic fluid duties.
- Series RDP Triplex/Quintuplex, SCE-M, CRP-M
- Plunger pressures up to 1500 bar, API 674
- Sealless containment shroud, API 685
- Ceramic plungers, check valves, magnets
Technical Diagnostics and Overhaul of Ruhrpumpen Process Pumping Units
Field engineering services cover scheduled maintenance, instrumented vibration analysis, and mechanical condition monitoring for Ruhrpumpen / Ruhrpumpen Group pumps built to API 610 and ISO standards.
Experienced field engineers execute laser shaft alignment, hydrodynamic sleeve bearing clearance checks, dynamic rotor balancing, and overhaul of API 682 mechanical cartridge seals.
Prior to startup following scheduled overhauls, pump casings undergo full hydrostatic pressure testing, dynamic thermal alignment verification, and multichannel vibration spectral analysis across all bearing planes.
Service agreements and OEM parts supply schedules ensure reliable operation under continuous refinery duties.
Installation, Precision Alignment and Commissioning of SCE Overhung Pumps
Ruhrpumpen SCE centerline-supported overhung process pumps are installed on rigid fabricated or cast-iron baseplates secured with non-shrink epoxy grout.
Rigorous piping strain checks verify that external nozzle loads stay well below API 610 limits, using dial indicators during flange bolt torque sequence.
Commissioning procedures include rotational direction confirmation with uncoupled motors, bearing housing lubrication flushes, process liquid priming with complete air venting, and gradual throttling to the rated duty point with net positive suction head margin monitoring.
Inspection Guidelines for GP and HSM Between Bearings Multistage Pumps
Heavy-duty between bearings pumps of series GP and HSM operating in BB3 and BB4 configurations handle high-pressure boiler feed and hydrocarbon pipeline transport.
Inspection routines measure rotor axial float across balancing drums or thrust discs, diametral wear ring clearances, and tilt-pad thrust bearing pads.
Major overhauls involve complete casing disassembly, optical shaft runout verification, precision labyrinth seal replacement, and hydraulic stage testing. Rotor stack assembly tightening follows calibrated torque sequences to preserve dynamic balancing integrity.
Preventive Service for RDP Plunger Pumps and SCE-M Magnetic Couplings
Reciprocating plunger pumps of series RDP compliant with API 674 demand routine inspection of suction and discharge valve cartridges, plunger packing compression, and power-end lube oil viscosity.
Sealless magnetic drive pumps of series SCE-M to API 685 require containment shell inspection and ceramic silicon carbide sleeve bearing monitoring.
Air gap tolerances between inner and outer magnet rotors are inspected to prevent physical rubbing during transient thermal expansions. All maintenance procedures strictly adhere to ATEX and explosion-proof technical protocols.
