Global Service and Technical Support The Preferred Choice for Water Injection Pumps Water injection is one of the key technologies oil and gas producers rely on to increase recovery rates. Trends toward higher pressures and more corrosive and erosive fluids create significant pumping challenges. Operations require efficient pumps that can reliably perform under high pressures for extended periods. Flowserve offers several innovative pump designs to address the industry’s needs. From axially split, multistage (BB3) units to diffuser- or volute-type double case (BB5) models, Flowserve water...

DMX High-Pressure Between Bearings, Axially Split, Multistage Pump ISO 13709/API 610 (BB3) The Flowserve DMX pump is fully compliant with ISO 13709/API 610, latest edition. It is engineered and built for high-pressure, heavy-duty water injection applications. Boasting a comprehensive range of hydraulic coverage, the DMX permits precise selection to ensure the best hydraulic fit, operating efficiency and stability. This helps to minimize operating expenses and extend mean time between repair. Nozzles are integral with the lower half casing permitting disassembly of the pump without...

Hydraulically Balanced Performance The DMX is engineered to perform reliably at the required hydraulic capacity while mitigating thrust loads. With as many as 14 stages to produce the required hydraulic capacity, the pump’s opposed impeller mounting arrangement effectively balances axial thrust over a broad operating range. Its double volute casing ensures hydraulically generated radial thrust loads are offset. Shaft deflection and vibration are virtually eliminated, resulting in prolonged bearing and seal life. Robust Rotating Element Ball Radial and Ball Thrust The DMX’s robust rotating...

WCC High-Pressure, Medium-Duty Diffuser-Style Double-Case Pump ISO 13709/API 610 (BB5) The WCC is a multistage, diffuser-type barrel pump with a tandem impeller rotor and a single-diameter balance drum to compensate for residual axial thrust. The standard cartridge type construction facilitates rapid changeout with a spare to minimize lost production. When process requirements demand a fully compliant, ISO 13709/API 610 pump but also call for a flexible, cost-efficient solution, the WCC is the optimum choice. With its extensive list of options and metallurgical choices, it can fit almost...

Single-Diameter Balance Drum A single-diameter balance drum compensates for residual axial thrust produced by the tandem impeller arrangement. The drum is designed to be plain or serrated as appropriate for the application to reduce leakage and optimize reliability and efficiency. It is installed via an interference fit against a step in the shaft and located axially with a split ring. A flanged drum design is optional. Robust Bearing System The standard bearing system on the WCC pump consists of heavy-duty journal radial bearings and self-equalizing, tilting pad thrust bearings due to...

HSO and HDO High-Pressure, Heavy-Duty Volute-Style Double-Case Pumps ISO 13709/API 610 (BB5) Rated for the most severe water injection conditions, Flowserve HSO and HDO special purpose pumps are manufactured to the strictest design criteria, often exceeding ISO 13709/API 610 (BB5). These pumps feature opposed impellers and dual volute designs, resulting in nearly balanced axial hydraulic thrust over the full operating range of the pumps. Single-suction (HSO) or double-suction (HDO) first-stage impellers provide the flexibility to meet a variety of NPSH requirements. Operating Parameters •...

Sag Boring Prolongs Wear Ring Life Sag boring is applied to all volutes nine stages and higher. The bottom volute casing is bored in incremental steps towards the center. This design accommodates the static deflection of the rotating assembly caused by the weight of the shaft and impellers when the pump is not operating. During start-up the shaft will straighten and casing rings will slide upwards to maintain clearances. This process eliminates rubbing of wear rings commonly found with slender shaft and high numbers of stages. Robust Bearing System Sleeve journal radial bearings and tilting...

WIK and WIKO High-Pressure and Ultra High-Pressure, Heavy-Duty Diffuser-Style Double-Case Pumps The uncompromising engineering philosophy adopted by Flowserve engineers when designing the WIK and WIKO pumps resulted in diffuser-style pumps that are unmatched in the industry. Fully compliant with ISO 13709/API 610 (BB5), these special purpose diffuser pumps include superior rotor dynamics, unequaled mechanical design and proven records of experience in water injection service. Typical Operating Parameters • Flows to 4000 m3/h (17 610 US gpm) • Heads to 7000 m (23 000 ft) • Pressures –– WIK:...

Unique Low Specific Speed Impellers Precision cast low specific speed impellers are statically and dynamically balanced. Impellers are double keyed and positively secured against axial movement by split rings and a shrink-fit on a stepped shaft. Large eye single-suction or alternate double-suction, first-stage impellers are available depending on NPSH conditions. Impeller hubs have integral hardened wear surfaces. Single-Diameter Balance Drum The single-diameter balance drum compensates for the residual axial thrust produced by the tandem impeller arrangement. The sleeve is grooved against...
